Corvette rear wheel was losing air so inspected tires and found no holes. Went to Corvette forum to learn this is a known problem on Z06 and grand sports. Seems GM has a problem with cracking. My crack is exactly what the forum members have. Hairline crack in the rim on the non-hub side. This is a safety issue as the rim could come apart at speed and cause a serious accident. I have no other damage to the wheel and have not had any curb damage. I baby this car and the same crack that many others have experienced appear.

Factory wheels cracked from normal driving on the inner lip, tire mechanic advised he's seen many of these on the Z06 wheels and it's a known problem however GM won't cover the defective wheels under warranty. The cracked wheel causes a slow leak end eventually can break if gone undetected resulting in a loss of control of the vehicle.

On or about September 11, 2018 I noticed my right front tire was low on air. I took it to les schwab tire and they repaired a leak from a screw. A couple of days later I noticed the tire was still going low I took it back and they informed me that it had a cracked wheel. I purchased a new wheel from Chevrolet and had less schwab install it for me. I just recently 2/22/2019 put new tires on the car and the dealership noted the brand new wheel I put on the right rear has cracks in it now as well as the left rear wheel which is losing air. These wheels are expensive I believe they retail for $800 each at the dealer and are defective and dangerous. Most of our miles are highway miles driving between san jose California and elk grove California between my offices.

We have had to repair then replace 2 rear cracked rims in the 1.5 years we have owned this vehicle. The first one was 3 months after purchasing it and the second one was in January 2019. After noticing both times that first the left tire was losing air a hairline crack was noticed on the inside of the rim. We had it repaired and it did not last so for safety reasons we needed to replace it. The same thing happened with the right side in late 2018. It was again suggested we repair it, then again the repair did not hold and we needed to replace.

Four rear wheels have cracked leaking air and have no external damage from road hazards. Two were replaced under the new car warranty and two were replaced under GM's purchased extended warranty. The first one, right rear, cracked on 11/19/16 with 18,843 miles on the car. The second one, left rear, cracked on 8/23/17 with 24,332 miles on the car. The third one, left rear, cracked on 8/14/18 with 34,854 miles on the car. The fourth one, right rear, cracked on 10/17/18 with 39,501 miles on the car. Calling the GM hot line I was told to contact my GM service department in regards to this issue. They told me the the wheel was designed to crack to protect the rear suspension !!! this is a huge safety issue. What would happen if that crack lead to a wheel failure at speed? I have all my GM service statements to back these facts up. GM needs to correct the problem!

The contact owns a 2016 Chevrolet Corvette. The contact stated that there was a failure concerning the rear oem factory rims. The contact stated that the metal was not structurally sound and there were cracks in the rear passenger side wheel. The failure led to low tire pressure. The dealer (george matick Chevrolet, 14001 telegraph rd, redford charter twp, mi 48239, (313) 531-7100) replaced the oem factory rim. The dealer also mentioned that they received several complaints for the same model, but various years, concerning the oem rear rims cracking and the low tire pressure. The manufacturer was notified of the failure. The failure mileage was not available.

My 2016 Corvette started having high frequency vibrations in steering wheel and interior panels with under 7900 miles of service. I complained to the dealership service department about the problem and found front wheels to be bent and could not balance the wheels properly. The dealership advised me to take my Corvette to another dealership that had better equipment than them. The second dealership inspected my Corvette and informed me that all four wheels are bent and cannot balance them properly. Neither dealership will replace the wheels under warranty. Thus far, GM as well, will not replace wheels under warranty. I attest that I have not driven my Corvette abnormally nor have hit obstructions or pot holes. I have never driven my Corvette on rough, gravel or dirt roads. I do believe this is a very serious safety problem that Chevrolet and GM should address before someone has a terrible accident because of these wheels!
