Air bags
232 reports28 crashes1 fire2 related recalls
“For the last 2 years, the car willl come up saying airbag system issues. There airbag sensor under the passenger side seat will randomly throw a code for the erorr and then turn off. It does not have to be a bump, move the seat, Just goes off. We have had it professionally scanned and it is always the same sensor with the issue. We noticed certian models had recalls but our was not on the list for some reason even though it fits all the other models with same issue. The cost to get it repaired and a chevy dealer is astromical. There are too many dates to count of the light and sesnor error.”
