| I have had a recurring problem with my new 2012 chevrolet silverado 1500 lt (5.3 liter engine) going into reduced engine power mode which also results in the disabling of stability control and traction control. this is a dangerous condition in that it results in a loss of power while operating the vehicle upon the roadway. an authorized repair facility has replaced the number one and two throttle sensors, the accelerator pedal assembly, the throttle body, the alternator, the computer, and a large ground wire behind the dash. a gm engineer was flown in and now the repair center is replacing the engine wiring harness. the vehicle (which was purchased less than three months ago) has been out of service for approximately 30 days. in researching this matter i have found that chevy has had an ongoing problem with this in various vehicles in its product line since 2003. although several service bulletins have been produced there does not seem to be a consensus regarding the cause of this problem. all of the parts associated with trouble codes c0242, p2127, and p2138 have been replaced without result. this condition could result in the affected vehicles being rearended, or, because of the loss of stability and traction control, result in a roll over. this needs to be addressed immediately. | |||

| There is a very high pitch noise the is emitted from behind the dash. this noise is distracting to the point that my wife can not ride in the truck let alone drive it. i have taken the truck to the dealer and was told by the service department that general motors is aware of this noise and it is acceptable. | |||

| Safety concern- potential trailering accident!!! it appears that chevrolet/gm has changed the wiring in their vehicles so that electric trailer brake controllers no longer illuminate the trailer brake lights when the electric brake controller is operated independently from the vehicle brakes. all brake lights work fine when the foot brake is applied but no brake lights illuminate when the controller overide is applied to operate the trailer brakes independently. there are times when trailering that one only wishes to use the trailer brakes to settle down swaying or on long down hill grades. 2012 vehicles are not wired so that brake lights also work off the controller overide switch. i have been towing for over 26 years and brake lights have always worked both on the foot brake and controller overide brake switch. this is a potential accident waitng to happen. if one applies the trailer brakes alone with no brake lights illuminating, this could cause another vehicle to slam into the back of the trailer and tow vehicle causing a crash. chevrolet states they cannot connect the trailer controllers to operate the brake lights as it would back feed power into the electronics of the vehicle voiding any warranty on the vehicle. trailer brakes lights only work as connected to the vehicle wiring when stepping on the foot brake. | |||
