Rear rim has cracked, have gotten repaired twice and cracked again. Car also has a vibration as if other rims on my car are bent or cracked. I currently do not drive the car very far because I'm afraid of getting strained somewhere. I have replaced the cracked rim with another rim from a rim shop that sales replica wheels

Both rear wheels cracked and I had to spend more money to replace them

I had to replace two wheels because they were cracking and the air leaks out.

Bent and cracked right rear wheel. All other wheels are out-of-round. Happened under normal driving conditions. Dealer wouldn't cover under manufacturer warranty. Stated it was normal wear and tear, but offered to sell me a tire and wheel protection package to cover future damage for $2500. I replace all four wheels with GM 2013 Corvette zr-1 wheels. I retained the defective wheels in my garage.

While driving the car, I continued to notice a vibration. It varied with speed and at times would be worse than at other times. This is known as a "beat frequency". I finally became very concerned, raised the car and found both passenger side rims to be bent. I had only had the car for 6 months. It came from a hendrick dealership. It is more than apparent this is another cover up by GM. I have a 2012 Kia forte that is driven on the same exact roads. It cost $12, ooo and has never bent a wheel. The Corvette Z06 msrp was $105,000. I had to purchase another set of wheels. GM is not capable of producing a car that is engineered correctly.

Purchased my 2017 grand sport in December 2019. It had about 5,000 miles on it. I not ever hit any road defects of note in any of these cases. I had to replace my first wheel within the 1st months (was leaking air from a crack in the wheel). A couple months after that I took my car in to get new tires and was informed that two more wheels had cracks in them. I had them welded. In July, I was losing air in another wheel and found it had a crack and had to have the wheel replaced. I only drive in tour mode (softer suspension) and even paid to get a suspension software update from GM in the summer to supposedly soften the ride after reading of others having this issue, it did not help to stop the issues. I have been driving in the same areas for over twenty years, had multiple other sports cars and never had any other damaged wheel besides this car. It is clear that the stock wheels are not strong enough for this heavy wide body car and they need forged wheels that I can't afford. To recap, I have about 10,000 miles on the car now and over the approx. 5,000 miles that I have drove it, there have been 4 wheels that had cracks on the inner side of the wheels, with no tire or other damage visible.

Soon after buying the car in May 2018, had to replace 3 of the 4 rims for being bent. I didn't hit any potholes or anything. Had to pay out of pocket because GM would not warranty the rims. On Sep 26,2020; one of the replaced rims (mentioned above) cracked and started leaking (left rear). All I do is normal driving and do not hit pot holes etc. There is obviously a defect in these rims. The car only has 45K miles and I've replaced 4 rims due to a defect that the manufacturer will not cover.

- Jamestown, TN, USA

When driving the car vibrated. I took the car to the local Chevy dealer to get the wheels balanced and was told two of the wheels could not be balanced because they were bent. In spite of my 3yr, 36K mile bumper to bumper warranty (which was in force) I was told Chevy would not cover the cost of repairs.

The contact owns a 2017 Chevrolet Corvette. The contact stated that the driver's side rear wheel, part number: 84073058, fractured under normal driving condition due to the manufacturer design. The contact stated that the driver's side rear tire became deflated. The vehicle was taken to a tire shop and the contact was informed that the driver's side rear wheel was fractured. The vehicle was not repaired. The vehicle was later taken to bellamy strickland Chevrolet Buick GMC (145 industrial blvd, mcdonough, ga 30253), and the contact was informed that the wheel needed to be replaced. The contact mentioned that the repair was not covered under warranty. The manufacturer was made aware of the failure and provided a case number. The failure mileage was approximately 22,600.

Right rear wheel has cracked, and will need to be replaced. I took car in to my local tire store because I though I might have picked up a nail, as the car was reporting low pressure in that tire. Tire store unmounted the wheel and showed me two cracks from inside edge of the rim towards center. Apx 2" each. No visible damage to tire or wheel indictive of a pot hole or other impact. I drove the car to take my girfriend out to dinner the night before and she also stated I didn't hit anything. Based on many many reports of similar failures on Corvette forums and pending class action lawsuits, I believe the wheels were defective when new. Because I have three other wheels which may have the same issue, I will have to purchase aftermarket wheels and hope they are a more robust design.

The car was stationary when I got a low pressure warning that my right rear tire had low tire pressure. I went to the corner gas station and got air. Then drove to my local tire repair to get the tire repaired. They removed the tire and wheel from the car and discovered the wheel was cracked in 2 places. I went to a wheel repair shop and he told me that he would not repair a wheel with 2 cracks. I knew this was a problem for grand sports since I have a friend who had the same problem with less than 1000 miles on his 2019 grand sport. I have all so read on the Corvette forums that many people are having this same problem with either cracked or bent wheels. I do not understand why General Motors is backing their wheels with their warranty. I have driven Corvettes since 1977 exclusively and never had a wheel problem. The vehicle was still within the 3 year warranty, but GM rejected the claim and refused any kind of compensation for the design defect of Corvette C7 wheels. I have since purchased a new wheel but I am worried that this problem may happen again with different consequences. My opinion is that these wheels are not designed for the vehicle.

Driving on regular road with no pot hole the right rear started to leak to find out after two days found out after the wheel was removed to see if it was the tire to find out the rim cracked with 7200 miles, them a month the left wheel started to loose air to find out the left rim with 2 cracks. With 7215 miles. No refund or assistance from the Chevy dealer. Thank goodness I had purchased tire insurance. There must be a defect in the cheap chinese steel. While I was in the tire repair shop, 3 others Corvettes with the same problems. One vet had the rim welded 3 times before he purchased a new set. GM should have this on recall or high safety concerns

- Staten Island, NY, USA

Had a constant slow leak for the past 7-8 months, finally took it in because I am planning a cross country drive and found out the passenger side rear wheel is cracked.

- Hermosa Beach, CA, USA

2017 Corvette with 6800 miles on it and the left wheel is bent causing a vibration when the car is moving. Discount tire said wheel could not be repaired. Left front wheel no bent.

- Petersburg, IN, USA

Normal driving caused major/minor cracks in 2 rims with moderate loss of air pressure over course of only a few miles requiring immediate exit from highway to address unsafe condition of car. Mileage of only 18693 on the car as of 6/11/2020. No coverage per GM even under new car 3 year/36000 mile warranty or the extended warranty we purchased. Cost to me of $1501.30. Pictures of cracks available as are the actual rims (tire service said they'd never seen anything like it in 40 years). Lawsuits pending against GM currently (class action). When they debuted the 2017 grand sport model on a 40000 mile test run they had a total of 10 cracked or bent rims due to poor rim construction. I fear that I'll lose a rim, puncture a tire and have an accident.

My wheels have developed cracks under normal use within 2000 miles of new. These leaks have resulted in air loss.

- Essex Junction, VT, USA

Both rear wheels have cracks from the inner edge to the tire bead area. Both rear wheels are leaking air at over 4 psi per week as verified by bubble testing of the cracks and tire pressure measurements. Both rear wheels and tires are in excellent condition with no damage of any kind from impacts. Rear tire tread at 12,000 miles is still safe, but close to wear out limits. My tire shop cannot install new rear tires on the cracked wheels. Martin Chevrolet in torrance ca reduced their diagnostic fee to $90 for taking photos and processing a warranty claim with GM. The vehicle was still within the 3 year warranty, but GM rejected the claim and refused any kind of compensation for the design defect of Corvette C7 wheels. GM support representative registered my case number 9-5956196745 and suggested that I have the wheels welded or buy two new wheels at my expense. The vehicle has been parked since 14 May 2020 due to risk of loss of air to rear tires. No other assistance was offered by GM or the dealer that sold me the vehicle, penske Chevrolet. The three year warranty was in effect but was not honored. One or more class action lawsuits are pending for this issue.

The passenger rear tire kept going flat and the leak could not be found. A tire service center eventually found 2 cracks on the inside lip of the wheel that extended inwards 1.5" into the barrel area of the wheel which caused the leak. This could lead to a wheel catastrophic failure. The shop manager said this is a common issue with this vehicle. The car was taken to a Chevrolet dealership for a warranty claim. The shop foreman filed the claim but GM denied it. The foreman also indicated this is a common problem. I purchased a new wheel and kept the old one. The white marks in the pictures are just a way to highlight the cracks. There are no indications of impacts that could have caused this issue.

I purchase the car as a one owner used. At the time of pick up the message on the dash read low rr tire. The service dept took the car for inspection. The tech came back and said he didn't see a problem. He stated he filled the tire and reflashed the computer as precaution. After a 5 hour trip home with the car in an enclosed trailer, I immediately put the car in heated storage for the balance of the winter. I didn't think much about the tire situation. When I brought the car out this spring the dash message said flat rr tire. I took the car to a reputable tire shop to see if there might be something in it. He called about an hour later telling me there were 2 cracks in the rear of the wheel. After checking on the Corvette forum I see where this is an ongoing problem especially with the grand sport. I am afraid to take the car out especially with family members. It appears that this is going to continue to happen and I feel I should be compensated. An after market set of quality wheels can cost $5000 or more and I don't feel I should be responsible for this. I don't only blame GM but also the selling dealer as I believe they knew of this problem. So as of now I have a useless $80 K car the car was purchased at bradley hubler chev. In franklin, Indiana. I purchased the car 2/17/20. It was already fractured.
