I recently (Christmas Eve) had the Service Suspension warning come on, very intermittently (twice). It morphed into a slightly larger issue a few days later when the traction control kicked in; my radio and gauges shut off and then came back on and the power locks opened and shut - this happened two or three times. Then today my 17 year old went to fill up the Sub for his mother and the vehicle went crazy with the power locks going up and down, the gauges/instruments losing power and then getting the power back over and over and over, including the radio and the rear view mirror temp/direction gauge. This happened all the way to the gas station and back. My daughter filmed the issue with her iphone and it is too large to attach but I will email it it if anyone is interested. If you have any ideas or can help, I sure would appreciate it.

Thanks-TK

 

I would check the ground connections as well as all other battery connections..

 

I will check them, thanks!

I'm sorry you experienced this issue with your vehicle. I agree with "in2pro", this may be due to a connection issue. There may be possible chafed, damaged, pinched, open or shorted wiring. This is just a suggestion and is not meant as a diagnosis.

I encourage you to consult with a certified technician for an inspection.

Please keep us posted.
