Tl*the contact owns a 2007 chevrolet silverado lt. The contact stated the throttle would stick anytime he attempted to release the pedal. The vehicle slows down very slowly. The engine continues to run at 800-100 RPM's until the brake is applied to stop the vehicle. The consumer also stated while stopped at a traffic light or a stop sign, the engine would occasionally speed up to approximately 1800 RPM's. The consumer also stated a new engine was installed on april 11, 2001 due to a faulty oil pump. The throttle body and engine control module were replaced twice, the hbac control module, oil deflector, purge valve and canister, maf sensor, wiring harness, speed sensor, co2 sensor, 175 amp fuse box, transmission control module and under hood wiring were all replaced. An engineer from general motors has worked on this vehicle at all three dealerships and has not been able to repair the problem. The manufacturer was contacted and they offered little assistance. The failure mileage was 46,000. Updated 06/22/11 updated 07/08/11 *bf updated 3/8/12
I am getting a noticeable vibration in the drive train at about 45 MPH. It finally subsides at around 55 MPH. I have had the oil level checked in the transmission and the rear end oil checked. All is ok in those areas. Contacted a local chevrolet dealer and explained the situation on the phone and I was told that is was normal for that make, model and drive train. Also had the underside of the vehicle checked to see if there was anything loose that might cause the problem especially the exhaust system and all is ok. Never had this problem before. Just started. Chevrolet won't bother with it.
On 10/18/2010 returning home from vacation, my right front wheel assembly suffered severe internal failure. The dealer in south carolina repaired my vehicle, and covered the expense of the replacement part and labor under the powertrain warranty. They also had to replace the front brake pads and resurfaced the rotors which were damaged to the severe internal failure of the wheel hub assembly. I can understand the malfunction of the part, it happens. But, on 12/17/2010 the left front wheel assembly suffered internal failure, again the dealer covered the expense of the replacement part and labor under the powertrain warranty. I believe their must be a problem for both front wheel hub assemblies to fail, I only have under 30,000 miles on the vehicle. Thank you.
2007 chevrolet silverado pickup truck. Consumer would like gm to buy back truck because of design flaws and suspected lemon *tgw the consumer stated onstar activated and stated the vehicle had been in an accident. The consumer called onstar to tell them that the vehicle had not been in an accident. The operator asked the consumer were there any lights on the dash. The consumer stated the air bag light was on. The operator attempted to instruct the consumer on how to reset the light, and stated if it didn't clear within two days to call back. When the consumer put the gear into drive and started to go forward, there was a tremendous explosion, dust filled the truck and onstar came on saying the vehicle had been in an accident. They vehicle was towed to the dealership. A week later, the consumer received a call from the dealership stating the explosion was caused by a poor design in the galleys in the floor, they went from the center of the truck to the drivers side door under a rubber mate. One of the galleys went through a rubber grommet which allowed water to leak into a compartment storing very high pressure compact cylinders for the air bag and seat belts. The water caused corrosion on the high pressure cylinders and caused the explosion. Also, the tailgate latch would not latch properly. The dealer found the pivots had seized. On cold starts, the transmission would hesitate and then a loud bang was heard. The dealer found a valve body bolt broken.
Chevy silverado 2007, the transmission jerks when stopped at a light. As if someone has bumped you from behind. It takes several seconds (5-20) for it to occur. This is the same problem I read by another member. My "07" silverado does the same thing. This problem started at about 20,000 miles. Truck has been to the shop 3 times, 1st they lubed the axle, 2nd they replaced the driveshaft yoke, 3rd time 1 week later they couldn't duplicate the problem . So now the problem still exist. I will be taking it back to see what`s next.
Thump after coming to a stop. After about 24,000 miles. I started feeling a light thump from the rear, as if someone bumped me from behind. Over the next few weeks it became very noticeable, so I took it to the dealer for investigation. The 1st time, they said the rear-end had the wrong lube in it & they replaced it. This seem to work for the next several weeks. Then the thump returned lightly at 1st & gradually worsened to a major thump. I returned it to the dealer & this second repair was that the lubed the rear-end & replaced the yoke on the driveshaft. This repair worked for about a week & I started feeling the light thump again. I took it back in again, left it all day & they apparently drove it around the parking lot & couldn't duplicate the problem. One of the service managers rode with me, around the parking lot & the problem wouldn't show up. It has since worsened again & I will take it back in once the problem gets a little worse.

Tl*the contact owns a 2007 chevrolet silverado. While driving 30-35 MPH, the speed does not increase on the vehicle, even when the accelerator pedal is depressed to the floor. This is a safety hazard when driving on the freeway. The vehicle was taken to the dealer, but nothing was repaired. The manufacturer acknowledged the failure, but stated that the vehicle was supposed to perform in that manner. The current mileage was 2,800 and failure mileage was 73.
Hesitation on acceleration. While merging onto an interstate highway pressed the accelerator to rapidly increase speed but the vehicle hesitated causing me to have to continue down the shoulder and actually stop to avoid a stalled vehicle on the shoulder. I have taken my vehicle to two different dealers to investigate the hesitation on acceleration both have stated that this is normal operation for the 2007 chevrolet silverado. Although I didn't have an accident with this particular incident I have noticed this hesitation during normal day to day driving. This is a safety issue.
