2011 Chevrolet Impala Problems

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?

Brake assist, traction control, stablitrack, and ABS lights continually coming on. When breaking while making a turn the breaks slip or give and then suddenly grab hold causing a grinding sound. Car wobbles while these lights are on causing a noticeable change in stability and control.

Service stabilitrak warning, followed by reduced engine power, then car starts jerking.

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.

"TAKATA RECALL" VEHICLE INVOLVED IN A REAR END COLLISION, WAS PUSHED INTO ONCOMING TRAFFIC AND HIT HEAD ON. AIR BAG NEVER DEPLOYED ADDITIONALLY THE BACK OF DRIVERS SEAT COLLAPSED INTO THE REAR SEAT

WELL I HAVE NOT TO MANY COMPLAINTS AS I DO MY OWN MAINTENANCE BUT SINCE I PURCHASED THE CAR USED AT 32000 MILES AT 83000 DRIVER SEAT HEATER UNION AND NOW AT 114764 MILES SERVICE AIR BAGS LIGHT IS ON DISPLAY AND LIGHT IS ILLUMINATED AT ALL TIMES.

Today, 6-12-2022, driving on US Highway 80 at 65 mph headed toward Phenix City, AL from Columbus, GA, the the engine shuddered, then the "Stabilitrack Service Light" came on, along with the check engine light, and a message for "reduced engine power." Then, the engine suddenly cut out as I was going uphill between the Riverchase Exit and the Summerville Exit. Luckily, I was driving and not my wife. I was able to glide the car back to the right shoulder of the road under ZERO power, and shut the ignition down. Cars were passing me at 65-75 mph, and I was very fortunate not to have caused an accident. After sitting there for about 5 minutes in 96 degree heat and my wife freaking out in the passenger seat, I restarted the car and eased it to the Summerville Exit, and slowly drove home, about another 6 miles. We were damn lucky not to have been hit by another car, as this happened on a what is essentially a freeway. After researching this , it seems this is a common problem being reported on this Model, the Chevy Impala. I'm sure Chevrolet knows about this...the company should be forced to recall this car model and fix it before folks start getting killed due to total engine failure...especially at a high speed like I was driving.

I NOTICED MY REAR DEFROST HAS QUITE WORKING. I FIGURED IT WAS A FUSE SO I WASN'T TO WORRIED ABOUT IT. WE'VE HAD A LOT OF SNOW RECENTLY AND FIGURED I BETTER CHECK MY FUSES. THE RELAY IS WORKING THAT IS LOCATED UNDER THE HOOD. WE TRACED TO WIRING THROUGH THE FIRE WALL AND DOWN TO WHERE IT COMES INTO THE VEHICLE (DOWN BY YOUR FEET). THERE IS A WIRING THERE AND ONCE WE DISCONNECTED IT WE NOTICED IT IS BURNT VERY BAD. WHERE THE TWO PIECES CONNECT TOGETHER IS MELTED AND IS BLACK. THIS COULD HAVE BEEN EXTREMELY BAD IF IT WOULD HAVE CAUGHT FIRE.

THE REAR DEFOGGER ON MY VEHICLE STOPPED WORKING. INVESTIGATION LEAD TO A VIDEO ON THE INTERNET SHOWING A MELTED CONNECTOR ON THE PASSENGER SIDE FUSE BOX. FOLLOWING THE STEPS IN THE VIDEO I FOUND THE EXACT SAME BURNED UP CONNECTOR UNDER THE CARPET OF MY VEHICLE. PHOTOS INCLUDED. THE CONNECTOR WAS CLEARLY NOT DESIGNED TO HANDLE THE CURRENT THE FUSE WAS ALLOWING TO FLOW THROUGH. THIS IS A FIRE RISK AS WELL AS AN INCONVENIENCE AS NOW MY REAR DEFOGGER IS INOPERATIVE. I NEVER SMELLED THE BURNING PART BUT LOST CLEARING ABILITY ABOUT THREE WEEKS AGO WHEN DRIVING IN COLD WEATHER.
