The electronic power steering intermittently fails while driving, especially during or after wet conditions. Without warning, the steering wheel becomes extremely stiff and difficult to turn, and a “Service Power Steering” message appears. The failure occurs at any speed and lasts about 1–3 minutes before returning to normal. This has happened multiple times under similar conditions. This creates a serious safety risk because it occurs at highway or city speeds without warning, making the vehicle difficult to control and increasing the risk of a crash. No prior warning is given before the failure other than the dashboard message at the time of the incident. Cause is UNKNOWN. There are numerous reports from other drivers describing similar symptoms, suggesting a potential widespread defect in the electronic power steering system or related components.

The stabilitrak notification appeared on my dashboard while driving on the highway, which immediately caused the car to slow down. It was a hazard as I had to maneuver over 4 lanes on a highway at high speed to move to safety. This issue has occurred three times and is currently on the fourth as the vehicle is at the Chevrolet dealer. It is going on three weeks on my fourth return in 6 months with no current feedback. I have taken the vehicle to the dealer each time for this exact issue which has occurred every 6 months after the initial repair, my vehicle was there for approximately three months as they stated I needed to replace the transmission. Six months from that date the issue occurred again and it was replaced as it was under warrant. The third time I had to pay for the repair as the dealer stated some sensors needed to be replaced. Now six months later again, it is at the dealer and I am waiting for the response. Each time this issue occurred, I was traveling at high speeds which almost resulted in accidents that I somehow managed to avoid. There were no other warning signs that this issue was going to occur. It just happens spontaneously. I have seen several complaints about this issue with Chevrolet made by mother customers going back as far as 2012 to no resolution but thousands of dollars spent with no real solution/answers.

While driving this vehicle, the Traction Control will turn off along with the Stabiltrack function. The transmission will drop into "limp" mode and function on a "basic" level. This causes the vehicle to loose power and become very sluggish to control or operate. A code for "loss of TCM communication" to be found in the computer via the ADL. To remove the code and restore communication to the Transmission Control Module, I have to remove and reinsert the wire coupling connection wire harness at the TCM. The TCM will now communicate with the ECM. This is a recurring problem solved by this action.

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.

A FEW DAYS AGO, I WAS DRIVING ALONG THE HIGHWAY AT APPROX 55MPH AND DECIDED TO CHANGE LANES AND I NEARLY RAN INTO A VEHICLE THAT WAS PASSING ME AT THE TIME. THIS NEAR MISS OCCURRED BECAUSE MY VEHICLE BLIND SIDE DETECTION SYSTEM WAS INOPERABLE. MY MECHANIC TOLD ME THAT THE SYSTEM SENSORS AND WIRE HARNESSES NEEDED TO BE REPLACED AND THAT THIS WAS A DESIGN DEFECT IN GM'S SIDE DETECTION SYSTEM IN THAT IT WASN'T ADEQUATELY PROTECTED FROM NORMAL MOISTURE DAMAGE. SINCE THIS IS SUCH AN INHERENT AND SERIOUS SAFETY HAZARD, THE MANUFACTURER SHOULD BE HELD RESPONSIBLE AND FORCED TO ISSUE A RECALL TO REPAIR THIS DEFECT. THANK YOU FOR YOUR ATTENTION TO THIS MATTER, [XXX] VEHICLE OWNER INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

WHILE DRIVING, SIDE DETECTION ERROR. ALL GAUGES STARTED JUMPING AROUND AND NOT WORKING. AFTER SHUT OFF CAR AND TRIED TO RESTART, IT WOULDN'T TURN OVER. CHECKED AND BATTERY WAS OK BUT IGNITION WAS ACTING LIKE NO POWER. TOW TRUCK TO THE DEALER. DEALER SAID IT WAS A KNOWN ISSUE AND THEY WOULD REPAIR FOR FREE. THAT WAS 6 WEEKS AGO AND IT IS STILL SITTING AT DEALER BECAUSE THE PART IS ON BACK ORDER. CHEVROLET WILL NOT COVER THE COST OF A RENTAL VEHICLE. I HAVE TALKED TO 4 DIFFERENT PEOPLE (I HAVE KEPT ESCALATING) OVER A 3 WEEK PERIOD - HOWEVER WITH NO RESOLUTION. AFTER MY LAST REQUEST FOR ESCALATION, THEY SAID I WOULD GET A CALL BACK IN 3-5 DAYS. THAT WAS 2 WEEKS AGO AND I'VE NEVER RECEIVED A CALL BACK. DEALERSHIP IS UNABLE TO PROVIDE AN ESTIMATE OF WHEN THE PART WILL BE AVAILABLE.

OCCASIONALLY THE DASH AND RADIO GO ALL BLACK, GETTING NO POWER. WHEN OPENING OR CLOSING SUNROOF, IT WILL STOP IN THE MIDDLE. IT EITHER STOPS COMPLETELY OR WILL STOP AND GO IN OPPOSITE DIRECTION AS THE BUTTON PUSHED. WHEN STEPPING ON THE BRAKE TO PUSH START, THE BRAKE GETS SUPER HARD AND THE DASH PANEL WILL SAY, 'PRESS BRAKE TO START.' I AM PRESSING THE BRAKE! MOST RECENTLY, 'SIDE DETECTION' IS DISPLAYING ON DASH PANEL AND BLIND SPOT LIGHTS ARE NOT LIGHTING UP ON MIRRORS. I'VE READ A NUMBER OF SIMILAR ISSUES ONLINE WITH THE SAME YEAR. I HAD THIS CAR BACK 7X FOR WATER GETTING IN THE TRUNK. IT LAYS WHERE THE SPARE TIRE IS AND THE CARPET ABOVE IS NEVER WET. EVERY-TIME THE DEALERSHIP SAID IT WAS SOMETHING DIFFERENT. OH AND IT STILL IS GETTING WATER IN THE TRUNK. DEALERSHIP SAID THEY DON'T KNOW WHAT ELSE TO DO! JUST YESTERDAY I WAS STOPED AT A RED LIGHT AND IT SOUNDED AND FELT LIKE THE CAR WAS GOING TO SHUT DOWN. THEN IT GAINED POWER JUST AS FAST. MY CAR ONLY HAS 27,000 MILES AND A LOT OF PROBLEMS.

THE OBJECT SENSOR MODULES THAT CONTROL SAFETY FEATURES LIKE BLIND SPOT ALERTS AND GAP ALERTS HAVE FAILED CREATING MORE PROBLEMS FOR MY VEHICLE. THIS IS A MAJOR SAFETY CONCERN AND SHOULD BE RECALLED BY CHEVY. MY DEALERSHIP SAID THAT MY EXTENDED WARRANTY WILL NOT COVER THIS ISSUE EVEN THOUGH IT IS ULTIMATELY AN ELECTRICAL PROBLEM AND NOTHING I DID CREATED THIS MAJOR ISSUE. THIS ISSUE OCCURRED WHILE I WAS DRIVING AND IMMEDIATELY HAD AN EFFECT ON MY DRIVING CONDITION.
