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
