I custom ordered my 2015 ZO6. Had back right passenger leaking air. I just left a Discount Tire to find out I’m fourth Corvette customer with CRACK in wheel they have got in last two weeks alone!!! Can someone please direct me who to contact? The Dealer to no surprise was no help whatsoever. Thanks early.

 

Even when the cars were covered by the B2B warranty cracked wheels were considered road damage. You've had your car for at least 6 years without an issue so it would be hard to claim a manufacturing defect. You are far past the warranty and the car is out of production. You are on your own.

Thank you for reply Bill. I had heard of a class action filed on basis of how Corvette (this is my third special ordered Corvette) owners drive and enjoy one or two weekend days a month, and time is showing these wheels were not what we paid for, although some time has passed due to the low mileage Corvettes this is occurring on…I’m just at 25K miles. Also heard other GM’s are doing same, such as Camaro.

 

My back right tire is leaking, I just put air in it. Currently don’t want to know that the wheel is cracked. Maybe this winter I’ll investigate more.

 

It won’t be hard for them to find.

 

Also know that you can’t get the same stamped ZO6 wheel you paid for when you purchased or ordered new. This is the difference when you look at them abs I’m sure the material is different, but unsure at this point.

See how the “ZO6” stamp is in completely different location.

 

Which ones are the originals? Mine has the stamp on the lip like in your 2nd picture.

 

The wheels are fragile and crack prone. There is a class action suit that has been ongoing for years. Your options are to buy another wheel and wait for another one to crack or buy forged wheels.

 

Do you have a link to the class-action suit?

 

Sorry to hear of your misfortune. Unfortunately this is one of the most widely discussed topics in the C7 section. It's an extremely common issue on Z06/GS models. I had 4k miles on my 17 Z06 vert and all 4 wheels were bent. Had them straightened and they were bent again by 6k. Straightened all 4 again. Then ponied up the cash and invested in forged wheels. 11k and no more problems.

 

I came from the 6th gen Camaro platform, it is rare to ever head of a cracked rim on the 2016+ Camaro platform and most of the time when we did hear of them it was from someone hitting something in or on the roadway. As Bill commented, you will be on your own. GM will not cover the wheels, even when under the B2B GM wouldnt cover the wheels. The class action suit even if it continues on is years away from being resolved and even then there is no promise us Z06 owners will get anything from the outcome of the class action suit.

 

Camaro wheels are not as wide and the suspension is softer than the Z or GS, have yet to hear of any of them cracking without a pothole or curb being involved. The combo of wide wheels and runflat tires with very stiff suspension is what likely causes the issues. That is why GM doesn't warranty the wheels with the bumper to bumper and the dealer will sell you a wheel/tire warranty for $1k or less to cover road hazard on the tires and any damage to the wheels. That's the proper solution if you want to replace the wheels with the same cast wheels they put on the car from the factory. Or pony up $4-5k for forged wheels and don't worry about it. I'd imagine the price for the car would be 5-7k higher if it came with forged wheels so I'm not sure the "wheels are not what we paid for" - I think they are exactly what we paid for to keep costs down.

 

Thank you for the reply, it definitely provides a different view. I will tell you I was tell when I special ordered ZO6 abs it came it that the wheels were around $2K a piece. Further research will show why and also note as I said you “can’t” replace the original stamped. ZO6 factory installed wheel with the original. Why? I don’t know yet, but I know the GM parts dealer told me the wheel I got to replace it with is the “only” wheel they can get as the original is not available. Why is best question because the replacement wheel has ZO6 not stamped in same place abs I am certain since the wheel was $500, it is nowhere close to same wheel as what came out on it in production. I accept responsibility for not getting extended warranty coverage, but again with the price paid for ZO6, being the premiere sports car sold by GM, you would also expect them to stand behind their product a bit since these wheels are failing with under 30K miles on them. So if they don’t address it will affect future purchases and success for their business. Or maybe the car will remain successful and Corvette fans will order with NO wheels abs purchase aftermarket ones with company doing better in that area. I hope we can all agree you can’t create too much more of an unsafe situation than putting wheels on a 650HP supercharges sports car which split open within first 30K miles on normal driving conditions (non track, no racing).

Yes, so you have link to info on class action suit? What brand wheels did you go with abs where did you get them?

 

The original which came on ZO6 from factory is in first picture…the only GM replacement they have for it is one in second picture which has ZO6 stamp more on the side of rim and more viewable like whitewall rim on side of tire.

 

My understanding is that GM went from using forged wheels on the C6 to cast wheels on the C7.

My opinion is that on the widebody cars this is an issue because the wider rim has a longer fulcrum to the load face. Long enough that flexing takes place resulting in cracks.

I'd suspect It's almost a guarantee on a widebody C7 that the wheels will gain runout and be out of true. Many owners never even realize it as the vibrations can be minor.

A buddy of mine just noticed his wheels to be out of round on his 19 Z06. He had the car up on his quick jacks and started the engine and put it in gear so the rear tires would spin in the air. Both his rear rims have noticeable runout in them.

 

So many such threads here, failed law-suits, etc., etc., etc. Go to the general C7 section and there is always a tread on the front page there, now with over a thousand posts. An "Advanced search" across the C7 sections will yield a gazillion faulty wide-body wheel threads. The only "answer" is quality, after-market, fully-forged replacements; consider it part of the price of admission. Btw, one poster showed using his faulty wheels for nice coffee-table bases.

 

Thank you for the info…it definitely makes sense. It seems like they would want to replace what has proven and is proving to be very unsafe.
