This "poll" has limited worth unless you add the tire pressure you maintain and mode you most often drive in. A recent thread talked about bent rims but the car was being run at 38psi!
With that said Hawaii roads are horrendous. 3600 miles at 30 psi in mainly Touring mode with no known problems, yet!
So many factors for possible damage.Is their simply a bad batch? Probably not.Their is thousands sold we may never know the ratio of good and bad.
Ohh,Your car and rim type would be Useful.
I still think lateral forces on the hub are part of the equation and not potholes or bumps in the road.....
Yes Sir sounds logical.Looking at the design of the rims the barrel's are very deep.The Hub with the support of the spokes,not spokes i'll call webbing are on the outer most part of the rim.
If the hub was more centered obviously they would be less (lateral) flexing.The suspension with tire width for traction limits you to this design.If more centered with these size tires you would be way outside wheel wells.
The materials used can't handle what they are designed to Handle.Sez the Armchair Engineer
Wondering if the bent wheels are happening when in Sport or Track, MSRC?
Last thing the Chev. dealership rep warned me of before leaving the Chev. store with my new 2017 FE2, 19" - 20" wheels, Stingray with MSRC; "If you drive on the streets/highways in MSRC Track mode, you're going to bend the rims/wheels."
.Needless to say, I don't run in Track MSRC whatsoever. There's no real point in driving legal speed limits in Track mode on public streets and
highways anyway.

Mine bent in tour mode... 30psi, normal driving and no major 'big bang'. These Grand Sport wheels are crap (probably just insulted crap).
Correct Z51-style wheels have not changed since 14 MY intro and were always 19/20s. You're thinking of the 18MY, when 18/19s were dropped as the standard base car size. I can't remember ever seeing a bent Z51 wheel report on this forum, which is not to say it hasn't happened. It's just very rare, and my theory is that the Z51 wheels spokes are much thicker.
I've been a tuned to bent rim reports for over a year
+ now. The GSes, and ZO6es, are the reporting rim benders. Knock on wood. ......

That is just Horse ****.You know and most know their is such a thing is Defective Manufacturing.A bad batch,a defective part.These low miles bends are a GM $UCK UP!
Just Awe full and not fair or right

100% with you bud, and am fighting them all the way.

Suggestion (if you're handling this yourself)...Contact folks like Motorweek, Vette magazine, etc and ask them to look into this "widespread" problem. An article about it certainly would help with PR pressure

Squeaky wheel (pun intended) and all that
heck yeah haha!
Ken, great idea... This has gone on long enough and is not an anomaly or something that can be hid behind 'field data'...

I would imagine the last thing GM wants (especially now with the plant closings and layouts) is bad PR. HOWEVER it might be a double-edged sword in that it might be hard to pull together public support for people buying a $60K+ car....

Yeah, but now that Honda Minivans are $50k, 60 doesn't sound so nuts!
Seriously, I saw with my own eyes a Honda minivan at the dealership that was just a hair under $50k!!! WOW.
That was the end of our wheel troubles . . . for about 4000 miles, by which point all four wheels were bent. All. Four. So we shoveled another $580 to our new best friend, the wheel-repair guy. That, finally, was our last instance of bent wheels on the Grand Sport. In all, we spent $4098 on wheel repair and replacement—seven repairs and three replacements, for an average failure rate of once every 4000 miles.

To the extent that I've followed this, it seems to be predominately with the Z06 & GS, assuming the wider width wheels. Coupled with mag ride. I *think* the Stingrays that have had this are all/mostly mag rides.
2014 base coupe with chrome stock wheels. When I bought new tires at 20K miles the right front passenger wheel was bent about 1/2 inch side to side. Wasn't giving me any problems so I decided to put the new tire on anyway. Now with 32K miles no further problems, no vibration or unusual tire wear.
15,500 on the clock no issues to date, West Virginia roads are the pits along the dot white line you gotta be careful when passing and then getting back to the right lane.....
