tas several members have complained here of poor, thin material in the seats and and doors. And have had theirs fixed under warranty. Take it to the Dealer and tell them it needs to be fixed. If you cant get them or gM to foot the bill (stance is everything my friend, get tough) here is a copy paste I did for another member......
GM uses the BBB to arbitrate unresolvable issues and by agreement has to go by the BBB'* decision. Here is their National number 800.955.5100 for arbitration hearing request forms. So if GM doesnt want to be cooperative try them. You dont qualify for the Buy Back Policy after 2 years/ 24,000 miles (whichever comes first) but if Your posturing * adamant enough, You may get them to throw ya a extended warranty. If all else fails, try these guys http://www.autosafety.org/lawyersandexperts.php
..... and good luck. You can also help yourself and others by writing Washinton and telling them your problems, find your States Senators and Representatives and e-mail them at www.house.gov/writerep/
