What owners report
Short excerpts of recent complaints, with personal details removed. Full reports are on NHTSA.gov.
Vehicle taillights failed to function when lights come on at night. I became aware of this when another motorist stopped beside me to tell me. Fuse and lightbulbs work when tested.
Air bag light comes on making it unclear if occupants are protected or if air bag will just go off on its own. Problem is wires in back door jamb become fatigued and break causing failure of air bags. Vehicle is also considered an inspection failure as well in massachusetts.
I've tried to have a garage repair/fix my heater/fan motor three times to no avail. Heater works on high only...and not on any other speeds.
