CHEVROLET Complaints

The vehicle suffers from severe, unresolvable electrical failures causing recurring loss of propulsion, shifting lockouts ("No Driving Conditions" / stuck in Park), complete exterior lighting failures, and loss of communication with the Restraints Control Module (RCM) and airbag impact sensors. The primary failure involves short circuits, open circuits, poor terminal contact, and thermal damage with melted, charred wiring and exposed copper in the main harness[cite: 6]. On May 25, 2026, OnStar telematics issued a critical red alert for the Regenerative Braking System[cite: 7]. All damaged components and diagnostic reports are available for inspection upon request[cite: 6, 7]. Safety risks include sudden loss of propulsion at highway speeds, total headlight and tail light loss during night driving, and potential non-deployment or malfunction of airbag restraint systems during a collision. The issues have been repeatedly reproduced and confirmed by an authorized dealership through 7 repair attempts between Sept 2024 and Apr 2025. Diagnostic steps included opening GM TAC Case 9-13634782861, consulting GM engineers, and testing 33 ground points. On Oct 28, 2024, the dealer and an insurance adjuster officially confirmed the failures are covered under GM warranty and unrelated to any accident[cite: 8]. Symptoms first appeared on Sept 10, 2024 (at 5,144 miles) with a "Waiting initialization to shift" message, blown Fuse 58, and loss of power to the ECM. Warning signs prior to subsequent failures included "Service Trans" warnings, "Reduced Propulsion" alerts, dim headlights, Check Engine Lights, SRS/Airbag warning lights, and total shifting lockouts after hitting road bumps. Despite replacing Fuse 58 (multiple times), Fuse 64, IP Fuse 7, the underhood fuse block, ECM connector terminals, headlamp assemblies, the RCM module, and multiple airbag impact sensors, the underlying electrical instability remains unresolved.

On start-up, intermittently the center display freezes, the HVAC system defaults to 76 degrees with the a/c and defrost stuck on with the blower on high. No driver input possible through the center display. Condition may clear by itself or not even through several shut downs. Numerous DTC's set. Always a CEL. For me, 2x dealer (repairs). They reprogram controllers. Condition not corrected. Possible HMI and/or HVAC controller hardware problem. Dealer doesn't know how to fix. Casual internet search indicates many identical complaints. Concern is, HVAC control is a basic function that should function correctly. Driving in the winter with no heat and a fogged windshield is a safety issue. GM is aware of the problem and has no fix.

So while I was driving my car going 60 on the highway it seemed to be having electrical issues all the lights on my dash popped on then popped off and only a few lights actually stayed on I can't remember exactly but the check engine and my abs stayed on and then on my screen it read to me warning power steering fault my headlights were dimming on and off like my car was going to die, so I had to pull over for my safety and other drivers safety, so after I pulled over safely I shut my car completely off and waited about 5 minutes and turned it back on when it turned back on the only light that popped on my dash was the check engine light, but the check engine light had actually been on the dash for a while after I replaced the 21 fuses that were missing that I didn't know were missing when I purchased the vehicle as is from a dealership the only thing that made me decide to check my fuses was because my check engine light was popping on and off and would stay off for a while then come back on a code reader said it was something to do with my turbo that code it was just very odd and the car was shifting weird 3 or 4 months after the purchase date XXX also after I put all the fuses back in a ton of codes popped up others safety and mine were at risk as I didn't really have control of my vehicle when it was doing that and it started breaking itself when I wasn't even hitting the break it was like jolting it's self and stopping slightly. I took my car to AAMCO Total car Care for a free diagnostic test, and then I had recently took my car to a Chevy dealership in Nampa Idaho off garrity boulevard because online it had told me there was recalls for my car and that recall was exactly what I was thinking had started off as the original problem originally leading into the other problems I got told to bring my car in then the fed me information saying pretty much it was a bust and that specific Malibu has no recall I think they just didn't want to work on it

LT275 65 R18 123/120 R DOT 1 BE BP AT 21 My daughter has pictures of the tires, all four tires (all bought at the same time) 05/6/23 from Discount Tire, are splitting along the side wall, originating at the tread line, we have talked with Discount tire, there are 40,000 miles approximately on the tires. They have been appropriately rotated and balanced. There have been no repairs of the tires. This is noted to be a defect, not normal wear and tear of the tire, per Discount Tire. They have offered 423.00 credit to purchase new, and have come back with 50% off new tires. Since this is a defect, verse actual wear and tear I do not believe that is appropriate. 75-100% of the replacement value. The tires should reasonably last between 5-6 years. The defect increases the risk of a blow out on any one or several of the tires. Discount Tire in Lubbock has confirmed that there is an issue, but I am not happy with their resolution.

Power steering goes out while driving in towns or on hiways.frequently comes back on while parked for a few hours or days. Unpredictable while driving.dangerous.

The Vehicle had a the BECM fail at 64,000 miles. This is a known issue that GM still refuses to recall, and is refusing to warranty

Transmission body throttle and TCM had to be replaced a year after purchase because of failing shifts, reverse failed to work completely.

My chevy tahoe vibrates when i drive and the dealership can not find the reason why it does that.

I am submitting this report regarding my 2021 Chevrolet Trailblazer because it has been experiencing the "Shift to Park" issue described in the GM bulletin 19-NA-206. Even when the vehicle is shifted into Park, it intermittently displays a "Shift to Park" message and does not recognize that the transmission is in Park. This issue has been ongoing and has not resolved despite normal use of the vehicle. It is frustrating to deal with on a regular basis, and it appears to be the same condition addressed by GM in Technical Service Bulletin 19-NA-206 that is available to view on the NHTSA website. I believe the NHTSA should push General Motors to issue a recall for this problem rather than relying on a Technical Service Bulletin. The issue appears to affect many GM vehicles, and owners should not have to bear the burden of repeated repairs or diagnosis for a known defect. I respectfully request that the NHTSA investigate this issue further and require GM to provide a permanent remedy through a recall.

My car was in Clarksburg Crown, Mitsubishi, and a lot that had no monitoring, and it was a sticker saying the car was not ready to be sold, and I still went with it trusting the crown Mitsubishi Car associate however there are fuses added to my car weather from them or from car auto tunes in Morgantown I’m not sure but my car has the ability to run without my foot on the gas or things happening to my to my acceleration
