The gm/gmc trucks with abs are unsafe and dangerous to the drivers and other pedestrians and vehicles on all roads. The Abs module light comes on and the brake warning light after driving normally and occasionally on its own and after a bump in the road. The abs system is unavailable/disabled when the light is on, the abs system has stopped and the light turned on when applying the brakes hard to avoid other vehicles and other actions such as steering away to avoid an accident arenecessary. While doing research on this problem I discovered that many gm/gmc pickup trucks have this problem with abs failure and the only sure repair being to replace the abs/ebcm module, there are codes stored for the abs system showing it has failed and stopped working. This problem is so large that an aftermarket industry has grown to address this issue providing rebuilt modules. I worked for a chevrolet dealership for 19 years and am an ase master technician and tested my own silverado and have had to replace my abs module, at my own cost as nearly all other owners, to ensure that I and my wife will be safe while driving. Please make the manufacturers responsible and liable for repairs/replacement so that the truck owners and others sharing the roads stay safe and alive.

The exterior of the wheel well separated from the interior cylinder of the wheel well. The issue appears that the wheel well (usually one piece) has cracked/separated into two pieces, likely due to rust. The car was parked at a store and made a loud popping sound, which could be heard from inside the store. The popping sound came from the loud separation of these pieces as shown in the attached images. This separation was powerful enough to bend and distort the entire exterior of the wheel/hub cap. The vehicle required a tow. This issue could have been a lot worse if the car was driving while the incident occurred. Upon inspection, the other wheel wells are likely to have the same thing occur due to similar appearance. For further details please see file number 529550.
