I have a defective wheel, it cracked. there was no impact, i have pictures and videos of the wheel spinning on a balancer to prove this. this is a problem that has become more common since wheel manufacturing went to china. gm is weaseling out of the warranty, no big deal. the danger is that i was informed that gm welds low pressure cast wheels to fulfill warranty claims. which the dealership had done to this wheel without my knowledge, again no big deal i already replaced the wheel and certainly wouldn't put that wheel back on my car. in my professional opinion this is dangerous. especially on a heavy car that is made to run on a track at 150 mph plus. a crack is caused by impurities in the alloy. if the alloy has impurities they usually aren't isolated to one specific spot. this crack actually grew from the lip into the barrel of the wheel in a couple days time, another way you can tell it wasn't caused by impact and that the impurities are most likely in several parts of the wheel. i really don't care about the warranty issue, i just don't want to hear about someone being killed from an issue like this because i neglected to report it. if you want that wheel for inspection or testing i can send it to you. there was no damage to my vehicle. i'm only able to send one photo. i have more and a video.
I was driving during rush hour at 70mph when my axle shaft abruptly disconnected from the car. it was shaking violently, and i was unable to accelerate. i was only able to coast through three lanes of traffic to get the car off the road. i almost died when the person behind me almost drove through me when the shaft disconnected and the car suddenly slowed without the brake lights going off.
