“I purchased a used 1998 olds Bravada. It has been an ok car except. The heater/air conditioner doesn't work properly. My dealer says you have to switch it back and forth from heat to cool in the dash somewhere (my question was, what is the thermostat button for then???). Also, the transmission or motor at 3000 rpms cuts out bad and jumps and could cause an accident if you are in the passing zone when this happens. Also, the dimmer switch doesn't work anymore. The windshield wipers do and the signals do but not the dimmer??”

NHTSA complaint #10186511, filed 2007-03, 35 miles

“Dear sir or madam, I am the owner of a 1998 Oldsmobile Bravada with a 4.3l vortec engine. Upon having my vehicle inspected, the mechanic at the dealership told me that my oil cooler lines were leaking, and that I needed to have them fixed ($433). I asked him about this problem, and was told that it was an inherent problem with GM's -- the lines may eventually fail and cause engine seizure. I wanted to do some price checking and find out just how widespread this problem was. …”

“Transmission problems, windshield wipers not working, headlights not working, awd problems, cooling system problems, fuel pump, control arm & ball joint problems are just some of the major safety issues on 96-99 GM blazers, Bravada's, & jimmys. These problems should really be looked into and recalled. Most problems starting right after warranty expired. Can't believe GM is getting away with this. Transmission went bad at 71000 miles and dealer says that they know there was a defect with the transmissions also problem (code 1870) but they will not cover the repair.”
