2015 Chevrolet Impala

The manufacturer patented Stabilitrak system continues to fail on my vehicle. Initial ODI 114406439. Dealership charged $1,7832.15 to replace transmission control module (TMC) on 11/5/21. On 12/22/21 vehicle indicated the exact issue (Service Stabilitrak), took vehicle to same dealership, awaiting response. The car is not drivable when "Service Stabilitrak" is indicated as engine power is substantially reduced. GM technical service bulletin PIC5992A seems to apply to my issue. However, Chevrolet and the dealership says it does not apply, but continue to charge for engine light analysis and unnecessary, expensive repairs. Your assistance would be greatly appreciated. Vehicle is once again inoperable (3/4/22) due to this issue (service stabilitrak). Consumer stated almost $3,000 was spent with no resolution. Consumer stated vehicle fixed with used parts from a junk yard— new parts were not available.

While driving at 70MPH on I10 in MS I experienced loss of power steering in heavy traffic. I received a notification on the dashboard of a problem, but it was difficult to maintain control of the vehicle and maneuver to the right lane to exit. The car was difficult to drive but I managed to pull into a large gas station and shut it down and ask for directions to a Chevy dealer. The Power steering returned when I restarted the vehicle and a Chevy dealer was several miles away, but the dealership personnel advised me to continue the trip since I reset the system, but could not tell me if it would reoccur. I drove another 250 miles to get home and did not have another incident. But after checking online forums I notice other such issues and this is quite dangerous at high speed and heavy traffic.

The stabilitrak system GM installed on my vehicle repeatedly indicates a "service" notification. Once this occurs, my vehicle loses power and the ability to shift into any driving mode. This issue began around 60,000, I currently have 77,500+ on my vehicle. GM issued a technical service bulletin (PIC5992A) for my vehicle, however, denies it's the issue and will only attempt a repair from a computer code, which they continue to fail to replicate. The occurrence of this issue is especially worrisome on any interstate highway. ODI 11406439

Around the first of October I was headed home with my family. As we were merging over to exit lanes to get on the ramp to exit the freeway the power steering failure light came on and simultaneously all my power steering was gone. I literally lost control control of my car. I was in the midst of turning when the car swerved and at 70 MPH it was very dangerous situation. My wife and I had just switched driving places several miles back. She panicked and said she couldn't imagine what she would have done if that had happened to her. She also swore to never drive that car again. I don't know how many times this has happened to others but I can say with all honesty this is a very serious problem. There wasn't an accident but I did cause everyone near me on the road to swerve and brake suddenly to avoid colliding with my vehicle. As of today the car hasn't been repaired and I haven't relayed this to the dealership. That being said even if they were for some miraculous divine reason to repair it for free the danger of this occurring again is still there. This feature is dangerous and I pray something is done about it.

WHEN I PUT MY CAR IN PARK IT ROLLS BACK LIKE IT'S A MANUAL IT DOES IT ALSO WHEN I AM IN REVERSE AND GO TO DRIVE. ALSO WHILE DRIVING MY GEAR SHIFT IF SOMEONE TOUCHES IT OR HITS IT WILL GO FROM DRIVE TO NEUTRAL WORRIED IT WILL GO TO PARK OR SOMETHING DANGEROUS ABOUT TWO YEARS THE VEHICLE ITS DONE THIS THE DEALERSHIP SAID NORMAL AND IT IS NOT.

I HAD THIS REPAIRED ONCE BEFORE AND NOW IT IS DOING IT AGAIN. THE STABILITY AND TRACTION LIGHT ARE ON AND ACCESS BRAKE SYSTEM LIGHTS AND TPMS LIGHTS ARE ON. IT MAKES A GRINDING CRUNCHING DRAGGING NOISE WHEN TURN THE WHEEL. SOMETIMES SO BAD ON THE DRAG LIKE ITS RUBBING AGAINST SOMETHING IT ALMOST STOPS THE VEHICLE. AS FAR AS SAFETY RISKS YES THE DRAGGING CRUNCHING SOUND STOPS THE VEHICLE AND IF TURNING IT SORT OF STALLS YOU, NO TRACTION OR STABILITY.THE WARNING LIGHTS REAPPEARED ABOUT A MONTH AGO. PEP BOYS COULDN'T GET THE TPMS SYSTEM TO WORK AFTER REPLACING TIRES BACK IN 2020 IN FEB.

Blind side collision monitor is not functioning properly due to faulty design which allows moisture to get into cabin where the monitor is installed. Causing the collision feature not to function properly and "service side collision" msg to show on the dashboard. I had this issue before and had it repaired by the dealer on 03/2019. The problem has since returned. But this time it's caused the functions on the dashboard ( gas, h/c and speed meters, digital monitor screen etc) to stop working where I can't tell if I have gas or my driving speed or anything associated with the dashboard info system, it blacks out. And now the alert light on the door mirrors continuously stay on even when there's no car on the side of my vehicle and even when the car is turned off. I took it back to the dealership and have been told that the collision monitor sensors AGAIN need to be replaced.

My left hand (front bank) catalytic converter near the cylinder head fell off yesterday at the mounting flange. It landed in/on my fan. I went online to find a replacement part and found GM service bulletin PIP5419a & b first issued in 2016.. That bulletin explains a known "defect" with the weld. The catalytic converter pipe cracks at the mounting weld. the TSB was issued for all Impalas from 2014-2016, all VINS all transmissions, all 3.6l RPO LFX engines. It says that GM is working on a solution for this concern. Why isn't there a recall on this defect? The file I've attached is not from my car but from the TSB. It's very similar to what my cars catalytic converter looks like.
