“Front passenger seat belt locks up and you are sometimes unable to use it. This had been happening more and more. At first you could keep moving it back and forth and it would immediately come loose but as time goes by, it is getting harder to get the seat belt to come loose.”
NHTSA complaint #10349565, filed 2010-08, 79,000 miles“The passengers side seat belt locked up and would not come out at all rendering it completely useless. We took the car to a chevy dealer as we were told that because the seat belt is a safety issue it should be covered, however we were told it is not covered and given an estimate of almost $300 to repair it.”
