All four rims are bent and cracked. This is true for almost all 2015 to 2019 grand sport and Z06 Corvette's. there are multiple class action lawsuits filed against GMC as of today's date. The rims are defective and GMC knows they are. But refuses to fix them. I paid over 50,000 cash for my 2019 grand sport, and it sits in the garage with 2 flat tires. Don't want to drive it at of fear something may happen. I have spoken with GMC several times, they refuse to help. Can you please help me?
Upon receiving my 2019 grand sport from the dealer by trucking company, all 4 wheels were warped/bent. I realized this when I went to drive it for the first time and around 50 mph the car started to shimmy/shake. I took it to my local Chevrolet dealer and they put it up on the rack and showed me all 4 wheels where spinning warped. I have videos of all 4 wheels.
In less than two years, this vehicle has had two cracked rims and four bent rims. In researching the issue online, I have found that this is a major problem, primarily for 2014-2019 Corvette grand sport and Z06 owners have with the aluminum-alloy wheels. A cracked wheel poses a safety risk as it could puncture a tire while driving. GM has done nothing to stand by their product, although these cars have a bumper to bumper warranty. There are class action suits that have been filed. There has been no specific incident that attribute to my rims having these problems. It is not an everday car for me and I seldom drive it.
The car is 2 years old and only has 4,900 miles. The left rear wheel has 2 small cracks. The rim was not damaged by any road conditions. The rim will no longer hold air and is structurally unsound. The car is driven to car shows and Sunday drives, it is not abused.

Both rear wheels on my 2019 Corvette grand sport are cracked. One wheel had a crack repaired at around 24,000 miles before I purchased it in January 2020. In August 2020 at about 28,500 miles, one rear tire started losing pressure. Upon inspection, the wheel was found to be cracked in two places. It cracked at the same spot where it was repaired and at a different location. The other rear wheel was holding air, but was found to be cracked as well. That wheel was never repaired before. There was no accident and no pot holes or road hazards hit to create these cracks. I drive the same well maintained roads that I drove my 2006 Corvette on for 120,000 miles without it ever cracking a wheel. Both rear wheels cracked in the 4,500 miles that I have driven the car. This represents a safety hazard. As of today, I was informed that Chevrolet only offers the same cast aluminum wheel that hundreds of others have also reported cracking or bending as a replacement.
My 2019 Corvette grand sport has had issues with the rims from day one. Currently there is les than 10,000 miles. Each rim has bent & now we have a cracked rim (about 1 1/2 inch long). The first time this happened we had only drive the car about 500 & was told we had 2 bent rims. This happened the following year and again this year. But this time we have a 1 1/2 inch crack on the rim. When we discuss this with the dealership we were told that GM would not cover any costs related to the rims. These cast rims are very weak, which could cause a life threating accident. Thankfully, it hasn't happened to us. But I have now spent almost $1000 to fix them. Since this will occur every year that I drive it. I most likely will have to buy new rims at a cost of about $1,250 per rim. Considering the cost of any Corvette you would think that GM would either cover the cost to replace. Or would have provided forged rims for a vehicle of this type as part of the Corvette. I would think that GM would have considered the safety feature on a performance vehicle and provided a much stronger rim.
My 2019 Corvette was purchased on September 20, 2018. I drove home thinking I wouldn't have any repair or replacement problems for some time on this new car. A few days later, as I'm reading the owner's manual, there are about four or five places in this thick manual that says my tires are "summer only" tires, and that it could be hazardous to drive on these tire in cold or wet weather. Well, summer ended only about 2-3 days after I purchased the car, so I immediately felt unsafe driving on the summer only tires. I went to my tire store and bought a set of all-weather tires. See uploaded photo 0973. I think it is unreasonable for all new Corvettes to only come with summer only tires! none of the dealers I negotiated with for this car would deliver my car with all season tires! later, related to my complaint number 11364386 pertaining to Corvette rim deficiencies, I had to prematurely replace each of the four new all season tires, one by one, due to rim problems causing tire irregularities where the tires meets the rims. There was lots of tread left, but damage to each of these tires where they contacted the out of round rims.
I began having rim problems shortly after purchasing my 2019 Corvette in September 2018. The car had a vibration and my tire store showed me how one of the wheels was out of round, so I ordered a new rim. See uploaded photo 0948. My next problem with vibration occurred with three of the rims being out of round, so I took it to a wheel repair shop to have them straightened. See uploaded photo 0949. Later on, vibration cropped up again, and I had one of those three wheel again straightened, plus welded in two places to repair air leaking cracks in the rim, so the rim would hold air. See uploaded photo 0950. Still later, that rim began leaking air again, so I had the tire shop again straighten and weld the leaking crack. See uploaded photo 0969. Still later, another rim would not hold any air pressure for longer than about four hours, so again that rim went to the repair shop to be welded. See uploaded photo 0972. In summary, it seems likely these Corvette rims, which come with low profile tires, are subject to loads which a casting cannot absorb when rolling over potholes, speedbumps, and other road anomalies. With a normal profile tire, this would unlikely to be a problem, but with low profile tires, the rims are only two inches from any road anomaly. Therefore, the Corvette rims should probably be manufactured using a forging process, rather than a casting process. Or, the Corvettes should be designed to use normal profile tires instead of low profile tires.
Left rear tire leaking air. Pressure would fall from 32psi to 14psi in only two days. Tire repair shop reported good tire, but noted 3 cracks on inside rim of wheel at tire bead. Chevrolet dealership noted cracks and submitted for warranty work which was denied. Only 16706 miles on 19 month old car.
Dangerous vibration as driving and braking at 6000 miles. After dealer claimed it was brakes, pads and my bad driving, replaced both. Didn't fix the problem and it even got much worse over the next 6000 miles. I took it to another dealer for help and found that I have 2 warped wheels. Bought wheel and tire protection plan at the time of purchuse but they wouldn't cover the wheels as the damage wasn't from road hassards or driving. But GM won't cover as they say it is driving and road damage. GM knows of the wheel flaws from other complaints but won't stand by their product.
3 bend rims were observed with no apparent reason. Brand new vehicle with less than 8000 miles, driven on good highways only. It seems to me a low quality materials used on the rims, very unsafe and unpleasant for a $76000 dollar car.
The contact owns a 2019 Chevrolet Corvette. The contact stated that the passenger's side rear tire was leaking air. The contact took the vehicle to a tire shop where he was informed that the rear passenger's side wheel was cracked and needed to be replaced. The contact had the wheel replaced out of pocket. The contact then took the vehicle to medved Chevrolet (11001 w interstate 70 frontage rd N, wheat ridge, co 80033) where they inspected the vehicle and made a request to the manufacturer to have the vehicle covered under warranty. The dealer then notified the contact that the manufacturer refused to cover the failure under warranty. The vehicle was repaired. The failure mileage was approximately 7,000.
I bought a new 2019 Corvette grand sport, after driving it a short time I noticed a vibration. I had the tires and wheels checked out and was told all 4 of my wheels were bent and I needed new wheels. I bought after market wheels because I had heard about the the problem of wheels coming out bent from the manufacturer, and General Motors was not honoring the bumper to bumper warranty on the wheels.
On two different occasions I have had cracked wheel rims on my 2019 Corvette. Both times I was driving at 65mph and a vibration occurred and almost lost control of the car. I went directly to the Chevy dealership and both times they told me there is no defect on the rims and they refused to replace them. Someone will be seriously injured and possibly die. Chevy needs to replace these faulty rims.unacceptable!!! I'm hoping ntsb will address this problem before someone is seriously hurt.
I first noticed something was off with my 2019 Corvette grand sport when it began to vibrate, shimmy, and shutter when I would drive above 30 mph. Later that same day my car began to have a slow leak in the rear driver side tire, I figured I caught a nail or something from the road. I inspected the tread area of the tire and did not see any visible markings that could cause a leak. I inspected my wheels within the inside wheel well and noticed a crack in the back driver side rim. I took my car to a nearby General Motors dealer and was told that this would not be covered under warranty and would have to pay for a rear rim. My car is barely driven, relatively new, with low miles and I did not recall hitting anything in the road nor have any road/curb rash to any of my wheels. Recently, I searched online and saw an article posted in a Corvette forum that Corvette Z06 and grand sport owners filed a class action lawsuit against General Motors for defective wheels that are prone to deform and crack, without any impact damage. Like other Corvette owners I was told that I was responsible for the replacement of the rim and had no choice but to replace it with another factory rim or purchase a set of comparable aftermarket rims at ~$6K. These rims are a huge safety concern as they could puncture the tires, cause additional air leaks, and possible tire blowouts. General Motors should be held accountable to replace these defective rims as they are putting their customers in huge risk of possible injury or death to the owners as well as other motorists on the road.
At 9212 miles, my low tire pressure indicator came on. I took the vehicle to northwest tire, bismarck, nd. They removed the wheel and found that the rim was cracked. The vehicle is still under factory warranty, on 9-29-2020, I took it to the kupper Chevrolet, mandan nd. They inspected the vehicle, found no damage. Other than the cracked wheel. They called General Motors for a warranty repair, which GM declined.
Vibration started a few months ago that felt like wheels out of balance. Had read about issues with bent and/or cracked wheels on grand sports. Brought car to the dealer, and also a tire company. Both determined 3 of 4 wheels were visibly bent when rotated on the balancing machine (I could see it as well). The fourth was not perfect, but better. The car is used on regular roads, never on a track, and at most has only encountered rough road patches. Car only has 4,500 miles on it.
Routine inspection during service revealed that the left rear wheel had developed a crack at the bead on the inboard edge. No other damage or defect was noted on the wheel at that time. The wheels were removed from service and replaced with aftermarket for safety.
Right rear wheel cracked in two places. Noticed air leak in August 2020. Occurred during normal driving. No recollection of any impact sufficient to crack wheel. Inspection revealed cracks across inner rim of wheel. Replaced all four wheels as precaution since issue apparently prevalent across entire C7 Corvette model line.
