Srs light came on .dealer said it is due to problem with airbag control and was a serious safety problem.I was then told it would cost me $975.00 plus tax to have it repaired. The car has less than 56000 miles .I would think the auto maker should be responsible for this type of safety problem.
My vehicle has had the air suspension fail 3 times and been replaced along with the pump according to a safety bulletin. It has just failed again and is going into the shop again now with no warranty. The air shocks were just replaced in nov 2010 and 10,000 miles later they again are leaking and failing.
