Long-Term Test: 2007 Chevrolet Silverado

Introduction

    0 Ratings
    Deciding to add a 2007 Chevrolet Silverado to our long-term test fleet was a no-brainer. It's been one of the best-selling vehicles in the country for decades and it was fully redesigned for 2007.

    Figuring out which Silverado was a little more difficult. There's a nearly endless list of body styles, engines and suspension configurations, not to mention several interior and trim options. We decided to look for a midgrade truck with a popular body style and typical features.

    This led us to the four-door crew cab as it's the fastest-growing segment of the full-size truck category. With four full-size doors, crew cabs are as family-friendly as your average sedan and they offer plenty of interior cargo room when no one is sitting in back. Although Chevrolet offers three different bed lengths, all crew cabs get the shortest bed which measures 5 feet, 3 inches long to keep it garageable.

    At that point, it was time to decide on an engine and suspension setup. GM's 5.3-liter V8 is the standard engine in crew cabs along with a four-speed automatic transmission. Although the vast majority of Silverados will have the 5.3-liter, we decided to upgrade to the top-of-the-line 367-horsepower 6.0-liter V8 for one simple reason — the Toyota Tundra.

    On sale in February, the next-generation 2007 Toyota Tundra promises a tow rating over 10,000 pounds and a six-speed automatic transmission for its 5.7-liter V8. Since we plan on adding one to the fleet, we figured it was only fair to equip our Silverado with the most competitive setup available.

    So along with the 6.0-liter V8 we would also need the heavy-duty tow package which gives the Chevrolet a tow-rating of 10,500 pounds. In addition to a more robust suspension, heavy-duty axle and 4.10 gears, the NHT package also adds a locking rear differential and four-wheel disc brakes. Although the locking diff would most likely provide all the traction we would need, we also decided to add four-wheel drive to give our truck maximum capability.

    Once we had our specs in mind it was time to find a truck. At the time, Silverados were just beginning to hit dealers so there weren't many on the ground. Before we made any calls, we headed to gmbuypower.com. It's one of the better manufacturer sites since it allows you to search the inventory lists of multiple dealers in your area. And once you find a vehicle you're interested in, you can actually bring up the window sticker to see exactly how it's equipped.

    There weren't many Silverados with the 6.0-liter engine around and even fewer with the heavy-duty tow package. We sent out a few e-mails to some Internet sales managers to see if they might have better luck finding the truck we wanted. We got a few calls from salesmen who said the trucks wouldn't be available until the spring and others who said we could order one from them right away if we came down. Yeah, thanks but no thanks.

    Finally we received an e-mail from a Frank Zicker (sorry, not sure which dealership) who had a better handle on the process. He had looked through his inventory system and found a truck equipped very close to what we wanted. It wasn't going to his dealership, but he went ahead and called the one where it was headed. About two hours after our initial contact, Frank e-mailed us back and said the dealer was willing to sell us the truck for $950 over invoice if we were interested.

    Despite the fact the truck had a few options we could have done without, we responded right away given the good deal being offered. Frank then put us in touch with Tim Connell, the sales manager at Connell Chevrolet in Costa Mesa, California. He confirmed he had the truck and agreed to the price Frank had quoted us. Turns out he was hoping to move a certain amount of trucks that weekend and the opportunity to sell our particular Silverado the next day worked for him as well as it worked for us. And just in case you're wondering, Tim didn't know he was dealing with Edmunds until he saw the name on the check the next day.

    Since then, we have put over 1,000 miles on our new Chevrolet Silverado. Initial impressions have been good as it was more than comfortable on a 600-mile round-trip to Las Vegas. To read our full rundown, you can check the full road test with all the details. And of course, like all our long-termers, the Silverado will get daily updates in our long-term blog.

    Summing Up

    Inside Line spent the past 20 months with the volume seller of GM's truck line, the 2007 Chevrolet Silverado 1500. This full-size pickup represents the latest generation of the Silverado, and its combination of comfort, convenience and function found a fan base among us, even though we've developed a bias for the Toyota Tundra in this category. But even the die-hard supporters of the Chevy truck were left questioning their loyalty when the Silverado's transmission gave out.

    Why We Bought It
    Our decision to add a 2007 Chevrolet Silverado to the long-term fleet was an obvious one. Though it looks only slightly different, this hardware has been comprehensively revised, a newsworthy event in its own right. We bought a half-ton example for a few reasons. First, the Silverado 1500 is the most popular version of Chevy's truck line, the model that most Americans can relate to. And frankly, this truck is plenty capable for our needs; we're not the kind of people who need an atomic reactor to microwave some popcorn.

    We had already completed a full test of the 2007 Silverado and conducted a comparison of the Chevy with its new-for-2007 peers, the Toyota Tundra and Nissan Titan. The logical next step was a long-term test.

    The impending arrival of the all-new 2007 Toyota Tundra in our long-term fleet provided further incentive for the addition of a Silverado. The presence of both trucks side-by-side in our fleet would offer an opportunity for an endless array of comparisons between the two pickups.

    It also turns out that grandma still needed her old furniture moved to storage (there's always someone in every extended family that has a weekend chore only a pickup can accomplish). So with these things in mind, we bought a 2007 Chevrolet Silverado 1500 and the long-term test began.

    Durability
    We quickly confirmed that the Silverado's 367-horsepower, 6.0-liter Vortec Max V8 offered plenty of power. But this truck didn't seem to have the proper hardware to get power to the ground. Though we knew GM was on the verge of integrating a six-speed automatic into its line of trucks, the Silverado was available only with a four-speed automatic. So we ordered up the four-speed, having no idea the price we would pay for this choice.

    One cost was power delivery. Karl Brauer, editor in chief of Edmunds.com, wrote on the long-term blog pages, "There are two elements here. First is the sluggish response of the cylinder deactivation that inhibits throttle response. Jump on the throttle and there's a brief but annoying delay as the engine switches from fuel-miser mode to power mode. Then you combine that with an unimpressive four-speed automatic and you find the V8 is no longer as rewarding as the horsepower specs suggest. We wish the six-speed auto was available."

    We opted for the crew cab half-ton version of the 2007 Chevrolet Silverado, which didn't so much affect how this truck drove down the road as it did the functional versatility of the package. Lead Senior Editor Ed Hellwig noted when asked to help a friend move, "No problem, I assured him, although I didn't really know whether or not the short 5.5-foot bed would handle the mattress set... .Everything fit fine as long as we kept the tailgate down, which of course required plenty of straps and tie-downs to make sure the mattress didn't slide out on the highway. Made me question the whole crew cab choice, as the 5.5-footer is the longest bed you can get with the 1500 four-door."

    Inside the Silverado's cabin, Chevrolet gets it right on the whole. We were able to overlook the annoying choice of specifying buttons rather than dials for the air-conditioning controls. And we overlooked the tendency for its comfortable cloth seats to collect lint like a wool sweater.

    This truck's interior is built with functionality in mind, as a truck should be. The rear seats fold up to expose a flat, unobstructed load floor. This leaves a sizable amount of interior cargo space when there are no rear occupants. Seems simple, but the Tundra gets it wrong by comparison. Lift the rear seats in our long-term Toyota and the floor is cluttered with a floor jack and an optional subwoofer. It's little details like this that go a long way in a vehicle that is built for function.

    A full test of the 2007 GMC Sierra with the six-speed transmission showed us that GM knows how to build a strong transmission for this truck. But when the aforementioned four-speed in our Silverado fell on its own sword in the middle of traffic that Sunday morning, we lost all confidence in the Chevy.

    Over a period of several weeks we had noticed a hard 1-2 shift while the transmission was cold. Once it warmed up, the shift action smoothed out. There were no signs of impending doom, so when we took the Silverado to Santa Monica Chevrolet-Buick for routine service, we asked the service personnel to look over the transmission.

    After two days we called for an update. We were told the 3-4 clutch was losing hydraulic pressure and the piston was replaced under warranty. The technicians also reconditioned the transmission. When we reminded our trusty service advisor that the problem was with the 1-2 shift and off-neutral gear engagement, he assured us this was the proper fix. We picked up the truck and two miles later a hard 1-2 shift served as proof that the original issue remained.

    We brought it back a few days later and were told by Santa Monica Chevrolet-Buick, "There is no problem. That is just how the truck shifts." Days later the problem came to a head with Senior Photographer Scott Jacobs at the wheel. Jacobs' voice was shaky on the phone. "The Silverado is parked at the office. The transmission locked up on me during a 2-3 shift. It screeched and lurched to a stop on Wilshire Boulevard. Drive doesn't work. Third doesn't work. Second doesn't work. First and reverse sort of work. The office was only a couple of blocks away so I was able to limp it back. An hour later and I'd have been on the Interstate 5 freeway headed to the Dodgers game. That was lucky."

    GM Roadside Assistance came to our rescue, towing the Silverado from the office to the local Santa Monica dealership. We called to confirm the status of the vehicle later that afternoon. The advisor was surprisingly frank with his diagnosis. "We've had a rash of these lately...with the input housing busting as the mileage gets up there. It should be ready by end of day tomorrow." The forward sprag was replaced, the transmission again reconditioned and keys to the Silverado were back in our hands the next day.

    Good news was that all gears worked again. The bad news was that the transmission didn't shift any smoother after this repair than before. We later learned there was an open technical service bulletin from Chevrolet about this issue. It made us wonder, if the dealer had already noted a "rash" of these transmission failures, why hadn't the sprag been replaced to begin with?

    Meanwhile, body damage was kept to a minimum during the Silverado's year-and-a-half of service in our fleet. A caved-in quarter panel was repaired for about $400 and took two days. A large crack in the windshield led to a new windshield for another $230.

    Dealer service for routine maintenance ranged from $35 for a basic oil change to $70 for the additional tire rotation and assortment of inspections. These prices remained surprisingly consistent regardless of dealership location.

    Performance and Fuel Economy
    Agility is not what the 2007 Chevrolet Silverado is about. Trucks are built for towing, hauling and general versatility. Nonetheless, we sent this Chevy through our usual battery of speed tests.

    Acceleration from zero to 60 mph required 7.2 seconds and the quarter-mile fell in 15.5 seconds at 88.1 mph. By comparison, our long-term Tundra posted a 0-60-mph time of 6.9 seconds and a quarter-mile of 15.1 seconds at 93 mph. In this test, the Silverado's V8 and four-speed automatic was significantly outmatched by the Toyota's 5.7-liter V8 and six-speed.

    When it came time to stop from 60 mph, the Silverado needed 139 feet. This was exactly 1 foot shorter than our long-term Tundra. Chief Road Test Editor Chris Walton commented, "The ABS is refined with little kickback once activated. But there does not appear to be a brake-assist program, as one 95 percent application of the brakes did not activate ABS fully."

    The 0.71g of lateral force generated by the Silverado is nearly identical to that achieved by the Tundra, while the Silverado's 57-mph speed through the slalom is slightly slower than the Toyota's 58.2 mph.

    Best Fuel Economy: 17.7 mpg
    Worst Fuel Economy: 6.8 mpg
    Average Fuel Economy: 13.2 mpg

    Retained Value
    We sold the Silverado during the fuel-price hysteria of summer 2008, so our first approaches to Chevy dealers for a trade-in were turned down flat, because nobody wanted a truck. The only takers resided at the nearby Carmax outlet, which offered us $15,000, which included some money off the top for a touch-up of some minor cosmetic issues on each quarter panel. But circumstance required us to take this paltry offer and get the truck off our corporate books.

    Had we been able to wait out the oil drama a few more months, the value of the our 2007 Chevrolet Silverado 1500 4WD Crew Cab would have climbed back to its current Edmunds TMV® price of $23,291. This would represent a loss of $19,806 from our original purchase price of $43,097, equal to a depreciation of roughly 46 percent. In comparison, our 2007 Toyota Tundra lost 38 percent of its value after nearly 26,000 miles because of the same fuel-conscious anti-truck market.

    True Market Value at service end: $23,291
    What it sold for: $15,000
    Depreciation: $19,806 or 46 percent of original paid price
    Final Odometer Reading: 32,080

    Summing Up
    Chevrolet does not disappoint when it comes to the new-generation Silverado 1500 pickup. When it comes to pure function, this Chevy is a strong contender in the half-ton pickup segment, and sales figures support its success with consumers. We had loaded ours up with all the trimmings, including a powerful 6.0-liter V8, four-wheel drive with a locking rear differential, a 4.10:1 final-drive ratio and heavy-duty tow package worthy of a 10,500-pound rating. The Silverado handled everything we could throw its way without breaking a sweat. It's clear that this truck had been created to slay the mighty Tundra.

    But rather than earn the praise it deserved from its functional excellence and day-to-day comfort and convenience, the Silverado left the ranks of our long-term fleet in shame. The question mark of reliability raised by the failure of its four-speed transmission ended its chances of winning any popularity contest with us. There comes a point when all warranties expire, and we didn't want to be stuck with the Silverado's keys in our pocket when it did.

    Still want a 2007 Chevrolet Silverado? Get the six-speed automatic. We can't speak to its longevity since we only tested one for two weeks. But we can speak to the unreliability of the four-speed.
