I have a 2015 Chevrolet Sonic. Every time I've been into the Chevrolet service center to have the oil changed, the Chevrolet service center underinflates my tires. The Chevrolet manufacturer calls for 38 psi in all four tires. The Chevrolet service center sets the psi in all four tires at 35 psi. Now, I'm questioning all oil and lube service centers. Are they also underinflating tires? this happened last about 7 months ago. I've used three different service centers since I"ve owned the car. Service centers in wichita, ks; Oklahoma city, ok; gulfport, ms.

On the morning of April 07 2016 my son was driving my wife to work on highway when they heard a loud pop, made his way through traffic to side of road. His 2015 Chevy Sonic which we bought for him last August 2015 with about 12,000 miles on it had a blown rear passenger hanook tire. He contact our local dealer about the issue. And was told "you have no warranty coverage in our system", he tried to tell them, but was rudely told "well if your parents had purchased or has a tire warranty we could help you". well that's a lie GM cover tires under their 3yr/30,000 mile warranty program I have submitted pictures of the tires, which I took earlier this morning when I got home. I want the tire replaced the dealer is not standing by their own warranty program and per my son was not to concerned when he told them the issue nor offered professional service
