C7 Lou

I noticed there were a number of posts about cracked Z06 wheels. I just had it happen to me and it looks similar to many of the other pictures posted on site. Many of the dealers covered this under warranty but Herb Chambers in Danvers is not![/I][/B] Does anyone have a suggestion on who I can talk to about this?

Its disturbing as there is no visible damage to the wheel otherwise and I'm worried about it happening to the other wheels. Thanks for your help.

If you are still under the B2B warranty I think it requires a little more discussion with the dealer. No evidence of damage from an outside force means the wheel should be covered. The warranty is supposed to cover design and manufacturing defects and a wheel that cracks without hitting something definitely falls into one or the other of those two areas.

2015 C7 ZO6 Wheel Cracking Relating to other ZO6 owners post with what appears to be the identical wheel style as my C7 ZO6 has.
In order to see if my wheels are cracked?Does the tire have to be dismounted to see if the wheel has a crack in it?
Does the tire lose air pressure?
What should I look for when the tires are still mounted on the rims? Is there a consistent area on the wheels that show where the wheel is cracked?
Rt. Front, Lt. Front, Lt. Rear or Rt. Rear?
I appreciate your feedback,

I ordered my C7 ZO6 with the identical Wheels that were an upgrade option. Of all of the stated cracked wheels, are they the same style with same design & powder coated black paint?
I know I will get some **** responses to my next question. But, What should I look for to determine if mine are or ever will be cracked? I say this as there must be a consistent area, such as the front or rear wheels? Left or right?
Does the tire pressure go down due to the crack?
Thanks for the topic!

My Grandsport wheel cracked. Does not look like GM will be replacing. Sad part is my previous 35k 2015 1LE came with forged wheels. My 74k sports car came with cheap cast wheels!

I can see why those were disallowed (rb185). Looks like scraping of the tire and wheel to me. The dealer must have thought the same. Sorry, about that, though!

And, a note on forged/cast strength... early C5 Z06 wheels were reported as forged in the US and they broke. I never saw a report of breakage with the later ones that looked, at least casually, identical and were cast in Italy. So, if all this is accurate, there is more to strength than manufacturing method.

They are not scraped. That's he goo from breaking the bead. The tire shop stopped as soon as they saw the crack and I did not clean it. I did not scape the inside of my rim. I've never been off road. Regardless, I can't blame GM for not wanting to replace, as they don't know how I've driven. I tried just in case, as I know I have not put a wheel wrong.

Owners with cracked wheels should report it to NHTSA as a safety issue. Maybe if they get enough of complaints they will force GM to do something

I think he's talking about the OP. His wheel looks scraped.

My rear driver side wheel is currently at the shop. Had a leak (losing about 10lbs a day), then it was discovered to be a cracked rim. No photo yet but I'll update this post after taking pics. Only 13,000 on the car, NEVER even tracked - certainly no hard impacts either. Total BS!

I would really push it with the service manager, and escalate it with GM. I agree this is nonsense.

It just came out of the water tank so it's dirty but NO damage whatsoever

Hairline crack, bubbling from expelled water.

Now I gotta go look, but mine is under wraps for the winter. I remember being able to buy wheel insurance at M.Benz on new deliveries, about $ 600. for life. A great deal if you just screw one up on a curb,
a $ 1,100. bill for ONE wheel. I asked to buy insurance in Sept. when I took delivery of my '17 GS SpEd. #663, not available.
This thread is about a GM problem/issue, but, if we could get wheel insurance we'd get a new wheel right away and let the Insurance Co. deal with GM.

I just had my first wheel crack at 23k miles. Never tracked or driven in race mode. Never hit any big bumps or potholes either. Car is still in garage but dealer wants me to have it towed in. I'm not comfortable bringing it in if they aren't going to cover it. Just submitted a complaint with NHTSA. Anyone have a class action suit open yet? I've owned 3 different Corvettes, (C6 Z06, C7 Z06), a CTS-V, and a ZL1 Camaro and never had this happen. Wondering if I need to lawyer up or let the dealership fight it.

2016 Z06/07 - I lost tire pressure today and pulled the wheel to see if I had a nail. I have 14,000 miles and have never tracked or abused the wheels. It has two one inch cracks about 14 inches apart in the rear drivers side wheel. Both on the inside edge and go in about 1 inch. Will call the dealer tomorrow and see what they say. It is exactly what these posts and several other threads are showing. Bad thing is...i don't know how to prevent it from happening again as I have no idea why it happened. Has to be a weakness in the metal of some sort that causes stress cracks. One crack is letting about 10 lbs per day out the other is not leaking air.

Simply put this issues is well documented with cheap cast wheels made in china or mexico depending which batch you have. Mate that with a powerful machine like the vette and some run flat tires and you have a recipe for failure. OEM wheels cannot handle the forces and loads on this beast and is another reason many of our customers have ditched their cracked whees and turned to Forgeline, HRE and other high end forged wheels which not only are lots stronger but lots lighter as well.

If we can assist anyone with new wheels that wont crack please call/text 440-915-6166 and we will set you up

My C7R didnt leave the showroom with the stock wheels.

Why didn't you buy GM wheel insurance when you bought it?
There are 2 types. Cosmetic & Repair/Replace. The cosmetic coverage only covers repairs to cosmetic damage. The other covers damaged wheel replacement.
BTW, if mine crack, I'll probably go forged anyway.

Landru

Precisely why C7 wheel insurance isn't offered.
Those in the know well understand there're problems. Production. Manufacture. Whatever.
Actuaries say C7 WI is a real $ loser for them, not to be touched w/ a barge pole.
Look how GM themselves treat owners w/ legit claims re (obviously) poorly manufactured wheels.
GM can't even SELL the risk in an insurance-hungry market.
So B2B be damned, given the slightest wiggle room and owners find themselves on their own dime.

Above suggestion re lodging a complaint w/ NTSB is spot-on, only solution towards possibly rectifying this nonsense.
Either that or buy quality aftermarket wheels, which seems many have towards permanently solving this.
Choose your poison.

The GM Tire and Wheel Protection with Cosmetic coverage will only repair Alloy wheels. If they need replacing, it is not covered - specifically stated in the contract. I bought the Tire & Wheel with Cosmetic protection; however, I am canceling based on the numerous reported bent/damaged wheels on GS and Z06s. I already placed an order for forged wheels from CW4L to get what I thought I was buying the GM Protection for.....peace of mind. Will cancel the contract as soon as my new forged wheels arrive!
