Most Recent Complaints
After getting into my parked car and starting it, the Stabilitrak warning message came on my display. This is the 2nd tike that this occurred. The first time it occured, my mechanic diagnosed it as a failed throttle body, which I replaced myself, (easy removal/installation). Now, a couple of months later, it occurred again. After doing some online research, it seems as though the position sensor on the accelerator pedal may be at fault. A lot, if not most cars today have a "fly-by-wire" system which replaces cables and such with sensors and motors. So, the accelerator, (gas), pedal controls the movement of the butterfly valve on the throttle body by sending a signal to the motor. I'm going to replace that... about $140 or so. I saw a YouTube video and the removal/installation is fairly easy. A lot of people are having this issue; maybe a recall is needed?

i own a 2011 chevy impala 4 door that has a very serious engine issue. I was on my way home and suddenly the service stability trac, and check engine light came on, then the message center displayed reduced engine power and low oil pressure then the engine shut off. I tried to restart the vehicle and it would not restart. I got it towed to a parking lot where it sat over night then it would restart but only for a few minutes. Once I got a scanner hooked up it had a p0642 code lost 5 volt reference circuit 1 and a cam sensor code I worked on this vehicle for two days and still have not found the issue. this vehicle needs a recall since this is a recurring issue with a few different model years of this vehicle and its always the same issue word for word, check engine light comes on, service stability trac, reduced engine power and low oil pressure lights come on the same p0642 lost 5 volt reference circuit 1. This is a very dangerous situation when going down the road and you lose engine power, steering and braking power. GM needs to correct this issue too many people have had this same issue.
