Long-Term Test: 2005 Chevy Cobalt LT

Introduction

    0 Ratings
    After 10 long years, Chevrolet finally replaced its aging Cavalier economy sedan, and its replacement, the all-new 2005 Chevrolet Cobalt, just may be real competition for imports like the Toyota Corolla and Honda Civic.

    Built on an all-new platform, the Cobalt is a very likable sedan, with a wide range of engines and trim levels to choose from. Plus it looks about 50 gazillion times better than the Cavalier ever did. But that new car smell can wear off pretty quickly if the vehicle isn't done right from top to bottom, so we decided to give the Cobalt the most thorough kind of test possible — a year in our garage.

    Twelve months in the supercharged SS coupe would have been nice, but we decided to take a more practical approach and ordered up a top-of-the-line Cobalt sedan in LT trim with the naturally aspirated 2.2-liter, four-cylinder engine.

    We figured it would be easy to find the Cobalt in the Los Angeles area, but a quick check of gmbuypower.com indicated that our search might take longer than expected. We wanted the LT in the Blue Granite Metallic Gray and we had to have XM radio. Even though we were flexible on all other things these "must-have" features meant going beyond Southern California.

    A Cobalt in our preferred color with XM radio, a power sunroof and a rear spoiler was located at Fairway Chevrolet in Las Vegas, Nevada, so we placed a call to GM BuyPower Manager Kevin Hopkins. He was no stranger to well-prepared Internet shoppers. He looked up the car we wanted to make sure it was still on the lot and was able to give us an out-the-door price within minutes. He then faxed over a deal sheet with all the information so we could examine it further. This proved to be helpful as we learned the Cobalt we wanted had tinted windows and VIN etching that cost extra. He eventually knocked the price down since we didn't really want the VIN etching, which is the practice of carving the car's identification number into the windshield glass for theft recovery reasons. The tinted windows, however, weren't a problem.

    Since this was during GM's much heralded employee discount sale, he sold us the car at a price actually below the employee discount number. Plus we got a $500 rebate. The sticker price, with the employee discount was $20,100. Our price was just $17,922.28.

    After finalizing the sale over the phone we drove the 275 miles to Las Vegas to collect our new wheels. Picking up the car was a breeze but we did run into a few annoyances registering an out-of-state vehicle back in California. Among other things, we were forced to get a smog test which set us back $50. We eventually got the right paperwork handled and the car was registered without any further problems.

    Going with the LT trim scored us slick-looking 16-inch wheels and a nice-looking interior with a standard four-speed automatic transmission, leather seats and a CD player with seven speakers. The darker window tinting also looks good with the Blue Granite paint. Although we could do without the rear spoiler, the Cobalt's look impressed many members of the staff, including Senior Editor Ed Hellwig who wrote, "I didn't think the Cobalt was particularly good-looking in pictures, but our long-termer looks pretty good in person, especially for less than $20,000."

    Our initial driving impressions have been good. The standard 145-hp four-cylinder gets the Cobalt up to speed quickly enough although it can be a bit rough at higher engine speeds. We would have liked to have seen a five-speed automatic in the Cobalt to give it a competitive edge over the competition, but we'll admit the four-speed works well. Mileage has also been a little disappointing, we're averaging just under 25 mpg.

    Commuting in the Cobalt has revealed a few more of its strengths and weaknesses. Light steering and strong acceleration make it well suited to urban driving. The XM radio we held out for is another big plus that makes the commutes a little less monotonous and we have to say we've yet to find a defect or have a mechanical issue. On the downside, the cupholder placement isn't ideal and the seats don't stay comfortable for very long.

    Of course, for less than $20K we weren't expecting a luxury car. Then again, there's a new Civic on the block now and the Mazda 3 is an economy sedan we rarely get tired of driving. If the Cobalt really can hang with the imports the LT sedan has another 11 months to prove it.

    Road Test

    January 2006

    Our little Chevy Cobalt is growing up. It's reached 5,000 miles of hard-earned experience as an Edmunds.com test car.

    Love was in the air as Senior Editor Erin Riches drove the Cobalt from Santa Monica to the Little Chapel of the West in Las Vegas and back, approximately 300 miles in each direction starting. Nope, she didn't elope, but she did chauffeur her father and his fiancée to their wedding in our Chevy sedan.

    She found the Cobalt to be a capable long-distance cruiser. Good midrange torque from the 2.2-liter engine and quick downshifts from the four-speed automatic transmission give it excellent passing capability. Only on steeper uphill grades did she wish for more power.

    The engine is also fairly smooth at higher rpm, but has quite a thirst. Fuel mileage has been all over the map, ranging from 16.8 mpg for a tank sipped in the city to over 32 mpg out in the open spaces of the interstate. Our average overall is just over 25 mpg.

    Despite the Cobalt's nonindependent rear suspension, its ride is smooth and refined. It's also nicely balanced through high-speed turns, though we suspect our sedan's 16-inch Pirelli tires help a lot in this regard.

    It's the interior of the Cobalt that garners most of the complaints from our staff. Erin notes that the Cobalt's backseat is one of the most uncomfortable in the economy sedan class. However, when the newlyweds climbed in back to be chauffeured to the chapel, they were too blissful to have any complaints.

    A base trim Chevrolet Cobalt finished 6th in our recent seven-car economy sedan comparison test partly due to its shoddy interior, and our loaded long-termer reinforces the results. Although the Cobalt is more likable with power windows and mirrors, a front-seat center armrest and a Pioneer stereo, it suffers from the same problems our test car did — hard plastic interior materials, inconsistent build quality and limited storage. Add in the cupholders that are incapable of keeping a cup of coffee secure and the Cobalt's interior isn't going to win any hearts over from its Honda Civic and Mazda 3 competition.

    The Cobalt's interior is nicely insulated from road and engine noise, but leaky rear window seals allow wind to howl in at speeds above 50 mph. On a road trip from Santa Monica to Northern California our Senior Photography Editor Scott Jacobs said there was so much wind noise coming from the rear windows he thought one was open.

    Of course, the interior isn't all bad. We found some surprisingly thoughtful features in our Cobalt, such as full illumination of all steering wheel buttons, window buttons, power lock button and power mirror adjustment. The consensus was that the Cobalt is a distinct improvement over its Cavalier predecessor.

    So far, problems with our test car have been limited to a squeaky brake pedal, which Jacobs took care of with a little shot of WD-40. So far it has fixed the problem.

    With GM's recent across-the-board price cuts, the newer 2006 Chevrolet Cobalt will be available for under $13K. Hey, GM, can we get a price adjustment? Department stores do it all the time. Well, it was just a thought.

    Road Test

    April 2006

    It might surprise some readers to learn that an Edmunds.com editor turned down the use of a 2005 Land Rover LR3 and instead opted to take the 2005 Chevrolet Cobalt LT on a family trip to Yosemite National Park.

    Yes, the LR3 drives magnificently and has gobs of space into which you can throw everything you could ever want to take along with you. But there is one little problem: It gets only an average of 15 miles per gallon and requires premium gasoline. The Cobalt, on the other hand, averaged 31.4 miles per gallon of regular fuel for the 672-mile trip.

    Before we go into greater detail, we should answer a number of questions that are, no doubt, rising to the top of your mind. Questions like: "But wasn't it ridiculously cramped?" Or, "Wasn't it a gutless wonder?" Or even: "What if you wanted to go off-roading?"

    True, when Americans go into the wilderness they want to take everything from home along with them. The other vehicles we saw at Yosemite were lugging all manner of conveniences and machinery: bikes, coolers, lawn chairs, tents, sleeping bags, video games, DVD players and on and on. It would have been impossible to take all this in the Cobalt. But Senior Consumer Advice Editor Philip Reed took what he needed for himself, his wife and their 15-year-old son.

    Packing the night before, Phil was doubtful he would be able to get the growing number of bags and packs into the compact four-door. He even began to reconsider his decision to turn down the LR3. But the next morning, the trunk swallowed their three suitcases, three backpacks and an assortment of hampers, grocery bags and a cooking stove.

    Driving to Yosemite from their home in Long Beach, the Reeds took turns riding in the backseat and found it acceptable. The only annoyance was the wind noise whistling through poorly installed weather stripping around the right rear door. Curious to see what kind of fuel economy could be achieved, the cruise control was set for 70 mph and they grew used to seeing assorted vehicles flying past them.

    The valley floor of Yosemite is at 4,000 feet elevation so it was a long climb from Fresno to the park. The Cobalt downshifted frequently on steep grades (albeit reluctantly) but the 2.2-liter, 145-horsepower engine proved more than adequate. On steep descents, when engine braking was necessary, the automatic's gear selector was a bit inconvenient to operate; Phil said that he would have preferred a sport shift feature for quicker changes.

    The real advantages of the Cobalt were its size and maneuverability. While the steering feel is a bit numb, once they got acclimated to it the twisting mountain roads became a romp. Very little body roll was detected at moderate speeds and the Cobalt felt confident and composed on a variety of terrain. Once inside the park, the small car proved easy to park and our editor allowed a degree of smugness to filter into his knowing smile as he witnessed larger vehicles contributing to the congestion of the park and increased emissions in the crystal blue skies.

    Now comes the best part. Being a real tightwad, Phil created a comparison of the fuel consumption of the two vehicles, the Cobalt and the LR3. The Cobalt used 21.4 gallons of gas, costing only $66.34 at $3.10 per gallon of regular unleaded. The LR3 has been averaging 14.9 mpg and to cover that distance burning premium unleaded would have used 45.1 gallons, which at $3.30 per gallon would have cost $148.83. The Cobalt, also a much cheaper car to buy, saved 23.7 gallons of fossil fuel and $82.49 (which the Reeds happily squandered on knickknacks in the park's gift shops).

    Finally, here is a list of things, both good and bad, that Phil noted after spending four days in the Cobalt.

    Pros:
    • The sunroof made for easy viewing of mountaintops and waterfalls.
    • Steering-wheel-mounted controls were easy to use — a luxury feature.
    • The sound system provided excellent quality and the CD changer was convenient.

    Cons:
    • The trunk opening is tight, making loading more difficult.
    • Climate control knobs feel cheap and sloppy.
    • No grab handles were available anywhere for passengers or driver.
    • There is no pull-down handle in the trunk.

    In other news, the Cobalt had an oil change and tire rotation performed at Albertson Chevrolet, in Culver City, California. We did have to wonder why it cost so much ($30 for a tire rotation and $45.72 for an oil change) but the service advisor was friendly and the work was performed quickly and efficiently.

    Our Cobalt now has over 8,000 miles on it and has performed reliably and economically. In an era of rising gas prices, this vehicle might be an attractive option, even for small families.

    Current Odometer: 8,323
    Best Fuel Economy: 32.6 mpg
    Worst Fuel Economy: 19.9 mpg
    Average Fuel Economy (over the life of the vehicle): 25.9 mpg

    Problems: None.

    Why We Bought It
    Chevrolet has never really had anything that could challenge the standouts of the economy-car class, the Honda Civic and Toyota Corolla. When Chevrolet finally replaced the aging Cavalier with the 2005 Cobalt, our hopes soared. Now Chevy's import fighter had a more powerful engine, sharper styling and a promise of improved build and materials quality. Naturally, we were curious enough to put one into our long-term fleet.

    We spec'd out a loaded 2005 Chevrolet Cobalt LT sedan. With leather seats, a moonroof, upgraded audio with XM radio and a rear spoiler, it listed for $20,100. With the employee discount and rebates we got it for $17,822.

    Would this be it — the vehicle that would finally make our staff proclaim, "Hey, everyone, GM finally has a real competitor in this class"? Maybe.... Maybe not.... A year in our long-term fleet would give us an answer.

    How It Drove
    Like many mainstream GM vehicles, the Cobalt's chief strength is its strong yet economical powertrain. The 145-horsepower engine is among the most beefy in its class. And although the automatic transmission is a four- and not five-speed unit, the well-spaced gears and quick response make the most of the engine's potential.

    Time and again, the positive logbook quotes centered on the Cobalt's performance. On a trip from L.A. to Las Vegas, Senior Content Editor Erin Riches found the Cobalt to be a capable long-distance cruiser. She noted, "Good midrange torque from the 2.2-liter engine and quick downshifts from the four-speed automatic transmission give it excellent passing capability."

    While on a family trip to Yosemite National Park, Senior Consumer Advice Editor Philip Reed found the little Chevy willing and able to serve his needs. Initially, Phil was concerned about the comfort and luggage capacity of the Cobalt. But during the 672-mile round-trip, the rear seat's comfort was judged acceptable — not luxurious, but not a literal pain in the butt, either. Trunk capacity was not an issue, as the 13.9-cubic-foot hold swallowed "our three suitcases, three backpacks and an assortment of hampers, grocery bags and a cooking stove." Phil did fault the Cobalt for having a tight trunk opening, which made loading more difficult, and no pull-down handle in the trunk lid.

    Facing various ascents, the Cobalt made a good showing. Although downshifts were frequent, the 2.2-liter four was up to the task of maintaining a 70-mph pace while fully laden with passengers and cargo. Phil was also pleased with the fuel-efficiency, as the Cobalt averaged 31.4 mpg for the completed trip. That's impressively close to the 32 mpg highway estimate displayed on the window sticker.

    Although the Cobalt's handling performance isn't going to cause Mazda 3 engineers any sleepless nights, it managed a curvy road better than we expected. Phil noted on his trip: "While the steering feel is a bit numb, once I got used to it the twisting mountain roads became a romp. Very little body roll was detected at moderate speeds and the Cobalt felt confident and composed on a variety of terrain."

    But while in interstate slog mode, the Cobalt suffered from a split personality. Although the well-insulated cabin kept road and engine noise well muted, our car suffered from excessive wind noise. Leaky rear window seals made their presence known at speeds over 50 mph, when wind howl would kick in. Senior Photo Editor Scott Jacobs said there was so much wind noise coming from the rear windows he thought one was open. Late in its tour of duty with us, the Cobalt's sunroof also developed a leak when it wouldn't close properly. We had the latter problem fixed, but the vocal rear window seals were not deemed faulty by the dealership.

    Inside the Cabin
    The interior of the Cobalt seemed to garner the most complaints from our staff. One editor noted that the Cobalt's backseat is one of the most uncomfortable in the economy sedan class. Another editor said the climate-control knobs feel cheap and sloppy and was amazed that there were no grab handles available for passengers or driver. A front-seat center armrest and a Pioneer stereo are nice features, but the Cobalt suffers from an abundance of hard plastic interior materials, inconsistent build quality and limited storage. Add in cupholders that are incapable of keeping a cup of coffee secure and the Cobalt's interior isn't going to win any hearts over from its direct competitors, the Honda Civic and Mazda 3.

    Of course, the interior isn't all bad. We found some surprisingly thoughtful features in our Cobalt, such as full illumination of all steering wheel buttons, window buttons, power lock button and power mirror adjustment. The consensus was that the Cobalt is a distinct improvement over its Cavalier predecessor.

    Summing Up
    We had hoped the 2005 Chevrolet Cobalt LT would challenge the imports that dominate this small-car segment. It is a pretty nice little car, but after a year and 17,000 miles behind the Cobalt's wheel, we don't think Honda, Mazda or Toyota have anything to worry about.

    Surprisingly, the faults seemed to stem from poor follow-through and lackluster design. The powertrain was often praised. And even the fuel economy was above average. But in the build quality and touch and feel departments — those areas right in front of your nose every day — it was a disappointment.

    Do good ideas cost more? Foreign carmakers have proved that intelligent design and follow-through on every level are possible. We hope that, while this GM product is a modest step in the right direction, next time it can go all the way.

    Changes to the Chevy Cobalt LT Since 2005
    2006: A new 171-hp SS trim level, which is available on the Cobalt coupe and sedan. Because this would cause confusion with last year's 205-hp supercharged SS coupe, that trim level is now called SS Supercharged. The remaining trim levels are also renamed: The base trim is now the LS, the former LS is now the LT and the previous LT sedan is now the LTZ.

    2007: A few new audio systems and wheel styles debut; a three-spoke steering wheel replaces the former four-spoker and GM's remote vehicle start feature joins the options list.

    Ups and Downs
    Ups: Affordable, strong acceleration, smooth and quiet ride, solid brakes, good crash test scores, high fuel mileage.

    Downs: Cheap interior plastics, cramped backseat, dire lack of interior storage, mediocre fit and finish.

    The Bottom Line: An agreeable little car that is a step up from the Cavalier it replaces. However, it doesn't measure up to the competition.

    Recalls and Problem History
    Recalls: Exterior lighting. The bulb shield can loosen or break because of vibration. If this occurred on a headlamp installed in a vehicle, oncoming drivers may notice additional glare, increasing the risk of a crash.

    Problem History:

    1. Squeaky brake pedal, fixed using lubricant.


    2. Stuck sunroof. The dealer repaired it under warranty but it broke again later.

    Dealer Service Reviews
    Albertson Chevrolet, Culver City, California

    April 2006

    The Cobalt had an oil change and tire rotation performed at 7,419 miles. We did have to wonder why it cost so much ($30 for a tire rotation and $45.72 for an oil change for a grand total of $75.72) but the service advisor was friendly and the work was performed quickly and efficiently.

    Santa Monica Auto Group, Santa Monica, California

    July 2006

    With 14,274 miles on the Cobalt we took it in for an oil change and tire rotation, which cost $62.66. We also asked the service advisor to repair the sunroof, which would not open past a certain point. The sunroof was repaired but later malfunctioned again.

    What Consumers Say
    "I have a 2005 base Cobalt that just turned over 40K. I am on my way back to the dealer for the sixth time for the same problem. The last time I was out of warranty and they goodwilled it for me. That was 3 weeks ago and now it is going back in today for the same thing. It starts out as a problem with what I think would be the transmission. The car takes forever to get up to speed (have to fan the accelerator) to get there and then when it shifts, it shifts so hard that it throws me back into the seat. The last 2 times they said that they were on the phone with the tech guys in Detroit and they told them to replace the ignition switch. Also let me point out that from day one I have had a problem getting my key out of the ignition. I have to play with the shifter to get the key out. Well yesterday the key stuck and I cannot get it out; the shifter will not lock. I have contacted my state about the lemon law and have been told that since it is an '05 I am out of luck."Bill Sully, October 2006

    "The more I look at the Cobalts, the more I like them. Especially the Coupe SS. As you can see I've been a loyal GM lover for a long time. Is my decision a normal one or am I going crazy? What kind of car is really the Cobalt? Good or bad?" — gosloup, October 2006

    "I have an '06 Cobalt LT2 5-speed. No problems with the car at all. Just do the normal 3K oil change. Nothing better than a Chevy!" — chevyguy, October 2006

    "I have a 2005 Cobalt with NO options and have put 21,000 miles on the car. We have had NO problems whatsoever and average 35 mpg on the highway and around 30 mpg combined. Mechanically, I have had NO work done on the car except oil changes each 3K and new tires at 20K. I could not be happier with the performance and reliability of this car. I am in no way related to GM or anyone that works for GM by the way." — nyguy1, July 2006

    "I own a 2006 Cobalt. From the day I bought it I have had nothing but problems and now 8 months later I am having even more problems. And with all these problems the dealership is telling me I got a good deal and a good car. I warn anyone who is interested in buying a Cobalt to seriously consider something else. I wouldn't wish this on my worst enemy." — cobalt bc, July 2006

    Edmunds purchased this vehicle for the purposes of evaluation.
