My truck should be featured in the newest installment of The Exorcist!! About once a week the airbag warning light goes on and turns on and off periodically while the truck is on but that isn't it. The seat starts moving by itself, sunroof won't work, RPM needle starts bouncing all over, check engine light comes on, headlights flicker, "service park assist" comes on, YOU NAME IT! The truck drives fine but when this occurs it makes me nervous to say the least. Took it to my mechanic he thinks its one of the vehicle's BUS's thats screwed up or a relay. Took it to Jeep and they have had my truck for two days and STILL can't figure out what is wrong with it!! Any thoughts?
