Three problems related to gasoline engine have been reported for the 1999 GMC Jimmy. The most recently reported issues are listed below.
Vehicle cotinously cuts out, causing slow but costly accident.
After reaching normal temp. , engine will die at random speeds. And requires complete powering down before will restart. This has almost caused many accedents.
Date given is the first incident. Engine quits for no apparent reason. It has happened at different speeds and different weather conditions. Dealer cannot find reason. Contacted gm and they just called the dealer. I am fearful that it will happen on the freeway and will cause an accident and someone will get hurt. Dealer says there is nothing they can do because they can't find the reason and they can't replace parts they don't think are broken.
