For the past few years I keep getting code P2138. I have spent several thousand dollars trying to get my truck fixed. I have replaced the accelerator pedal at least 3 times. Replaced the throttle body. Did a complete rewire. Replaced the ECM and still the dealership can-€™t figure it out. Every time I leave I-€™m hopeful the problem is resolved but then a month or two later I will be driving and then my truck will lose engine power. Someone is going to get killed because of this if they haven-€™t already. Extremely frustrated.

At about 90,000 miles the cruise control stopped working and when it is warm outside the passenger's side door electrical lock will not work. It tries to push lock to unlock position, but only pushes it half way. I have read a lot about these concerns on this model vehicle. Is this 2 recalls? it should be. This is not a cheap fix.

I was driving my 2009 Chevrolet Silverado one morning on my way to school(luckily I wasn't to far from home when the incident occurred) when the vehicle lost power and the dash showed the check engine light, service stabilititrak, and service traction control. When the incident occurred I was in the middle of the road when my vehicle began to decelerate and eventually was not able to go past 45 mph. I pulled over and my vehicle and parked, shut off the engine, and then started it back up only to show the same icons on the dash. After turning around and slowly returning to my house I shut the vehicle off and had to take my wife's car to work. Under other circumstances this could have gone extremely bad and an accident may have occurred. This seems to be a common trend on the internet and forums and needs to be addressed by GM!

Was just leaving funeral and started vehicle then service traction control, service stabilitrak, traction control off, stabilitrak off, loss of control noticed displayed. Tried to drive but experienced bucking and drastic power loss. Took to dealer who said failure was due to faulty throttle position sensor - a problem he indicated was recurring for that vehicle. Luckily he serviced under vehicle warranty. But disappointing to see at less than 40,000 miles.

While pulling onto I83 I pushed down on the gas pedal to quickly accelerate to merge. The pedal became stuck on the floor mat sticking it in the down position causing the truck to rapidly accelerate after I left my foot off the gas pedal. I had to use my feet to pull the floor mat back towards the seat to release the gas pedal. This has happened several times over the last few years, most recently November 20, 2012.

I was at 60 to 65 mph on an interstate and the truck powered the motor down. The electronic stability control module light came on and the service engine light. I was able to get off at the last safe exit for quite a way. Onstar recommended not driving it to the dealer. The dealer did the diagnostic and at 28000 miles told me it was the throttle body assembly. It took 5 days to get a "new" one.( aprox 1/26/11) on aprox 12/15/11 an almost identical thing happened, mileage 50,000. Out of warranty I took it to a local shop. Their computer test concluded a throttle body assembly malfunction. $450 to repair. Call the dealer " no that is under warranty" dealer concluded that it "just needed cleaned". prior to service (I rely on this truck for work, I can not get a ride, I can not ride a bus) I was able to "reset " the stabilitrack ( the button would not turn it off) by pulling 4 fuses under the hood fuse block. But boy when it had enough the truck would power the motor down and within 15 seconds the truck would die right where it was. 5 mph, or 15 mph no power nothing, brakes, steering gone.

I have a 2009 Chevrolet Silverado 1500. The cruise control does not slow down the vehicle on grades or ever small slopes. The vehicle free rolls as fast as you will let it in over drive, 3rd gear, 1st or 2nd. There is no engine breaking at all. GM says this is proper operation for the vehicle, and there is no software or mechanical fix for this problem. I have a 2004 of the same model and it works perfectly, with very effective speed control. This is very unsafe, and actually in my opinion cannot be considered to be cruise control at all. My dealership told me this is an ongoing complaint, that GM will not acknowledge as a definite defect in design. The same day my vehicle was being examined, the local police had one of their trucks of the same model year in the shop with the same complaint. I have not had an accident, but cannot use this option on the vehicle, I can only ride my breaks down slopes to slow the vehicle down.
