2019 Chevrolet Corvette Complaints

WHEELS — Filed 08/20/2024

Well known and documented failure of 2015-2019 Corvette ZO6 and Grand Sport wheels cracking prematurely due to poor manufacturing process. General Motors/Chevrolet has already publicly admitted liability to avoid court cases already filed. They agreed to offer extended warranty to owners of affected vehicles in 2024, offering full replacement cost of defective wheels. They assigned a company, Analytics Consulting LLC of [XXX] , to administer the claim process. I received my claim form in July of 2024. I filled out and supplied all required documentation on August 20, 2024, they later acknowledged receipt August 22, 2024. All claim forms were required to be sent by January 25, 2025. They informed me by phone call that they would not begin processing claims until March 1, 2025. All through the Summer of 2025, after several phone calls, that no information would be released as to the completion of processed claims until all claims had been completed. No time line given or offered. To date there has been no other information or updates on when the claims will be paid. I have filed a claim with the State of Georgia Attorney Generals office, they were unable to help. I have gone to the local ABC news station where they did a story on the issue, no resolution. This is a national issue for all owners of the affected vehicles. There have been many articles and videos published regarding the issue. Analytics Consulting is holding those with a legitimate claim hostage. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Two of the wheels of my 2019 Corvette have cracked. GMC has turned this issue over to Analytics Consulting LLC to reimburse those owners that have had a problem with cracked wheels. I submitted a claim for one of the wheels, in July of 2025 and have yet to hear from them. In the mean time I had another wheel crack but I can not claim that one because it's beyond the date they set. I contacted GMC and their response was they couldn't do anything for me. My point in this whole matter is that I've had two wheels crack but I still have two that might crack. GMC admits to defective wheels and yet there was never a recall. They are playing Russian roulette with Corvette wheels that are on the road daily. I've had costly repair bills for wheels that were defective when GMC put them on my car. These wheels could crack at any point while I'm driving or God forbid when my wife is driving. She doesn't want to ride in the car anymore because she feels it's unsafe. I can't sell it because I would have to affirm that these wheels might crack. Who would buy my car? The value of my dream car has plummeted. I'd like reimbursed for the two I've already paid for and all four wheels replaced with wheels that have been tested and new ones that are proven to be safe. Is it too much to ask GMC to build safe cars? They say it is important to them that the customer satisfaction and safety is utmost. I'm asking them to live up to that so I need your help to see that they do.

The contact owns a 2019 Chevrolet Corvette. The contact stated that while driving approximately 40 MPH, the accelerator pedal was depressed, and the vehicle shook and shuddered abnormally. The contact stated that the failure had been constant since purchasing the vehicle. There were no warning lights illuminated. The contact believed that the shudder was due to the high-performance engine. The contact had not taken the vehicle to the dealer to be diagnosed. The contact stated that during an alignment at a dealer, the service technician informed the contact that the shudder was a known failure caused by the transmission fluid, causing the torque converter to shudder whenever the accelerator pedal was depressed. The technician provided the contact information on TSB: 19-NA-018. The contact stated that the vehicle had not been diagnosed by the service technician using a diagnostic machine. The manufacturer was informed of the failure and referred the contact to the NHTSA Hotline for assistance. The failure mileage was approximately 30,000.

A 2019 Corvette with 3,400 miles began to demonstrate a transmission torque converter shutter. This became rapidly and progressively worse causing driving to resemble being on a washboard road surface. The servicing dealer was familiar with the problem with this transmission and did resolve the issue with an expensive transmission fluid flush and exchange.

GM has a well known issue with the transmission fluid used in assembly on a range of cars and dates which include my 2019 Corvette. The fluid used fails/ is defective. The process to fix the issue is to flush the fluid out and put in a different fluid. In the case of my Corvette, it actually requires a very expensive triple flush to ensure all of the original Dexron fluid has been removed and is replaced my Mobil fluid. The process is explained in an 18 page service bulletin 18-NA-355. This bulletin states that if a customer comes in complaining of shake/shudder during acceleration between 25 to 80mph or when the trans is not actively shaking, then there is no need to further diagnose. Just follow the procedure in the service bulletin. In other words, there is no need to investigate further because we already know what the problem is which is the defective Dexron fluid. This was my exact experience with the shake/shudder and the triple flush completely fixed the issue. My vehicle has 17k miles on it so this was no a normal maintenance issue nor would you expect a full flush of transmission fluid at 17k or really at any point. Perhaps adding some fluid at some point would be reasonable. Having to completely remove all traces of the assembly line fluid with a completely different fluid clearly indicates a defect in the original Dexron. The service bulletin clearly indicates GM knows that the Dexron is defective. A final note, a quick web search of this issue will bring up pages of threads of people who have experienced this exact issue. Please hold GM responsible for their error. Thanks
