Rim corrosion resulting in loss of air pressure. The inner portion of the rim is corroding causing the tires to loose pressure. Depending on the amount of corrosion this could lead to a catastrophic failure at some point due to sudden loss of pressure. I took my vehicle to a tire shop thinking there was a puncture causing it to loose pressure. The manager explained to me that the pressure loss was due to corrosion of the alloy rim and that it is common with Chevrolet vehicles with factory alloy rims. The only solution to the problem is to have the rims possibly refurbished or replaced.

The car was slowly making right hand turn when we heard a loud noise and stopped the car Once we got out, we saw that right wheel was completely torn out. We have videos and pictures. If it would happened on the higher speed, we would be dead. The car shop told us that they never seen anything like that in the past. Per their report, upper control arm broke off then the rest followed: lower control arm, ball joint, outer tie rod, poss inner tie rod, sway bar link, abs sensor connector. Consumer also learned from dealer that certain parts do not exist anymore and new ones are available.
