Owner Complaints (4)
Your vehicle's rear window defroster caught fire and began smoking while the car was warming up after a remote start. The fire self-extinguished, but about 45 seconds later your driver's side rear window shattered from the heat. This is a known defect related to a thermal event in the defroster unit. The fix will likely involve replacing the rear window defroster assembly and possibly the rear window glass.

While idling with the rear window defroster on, you noticed smoke coming from the rear window, which then shattered without warning. You disconnected the defroster fuse to stop the problem and drove home safely. The defroster repair may involve replacing the rear window heating element or wiring that overheated, or installing a new rear window with an updated defroster system.

Your fuel gauge is intermittent and unreliable — sometimes it doesn't display at all when you start driving, may take several miles to activate, or quits unexpectedly while driving. The problem started around 40,000 miles and gets worse after the truck sits for a few days. The gauge works fine sometimes, but you can't predict when it will fail. This likely involves testing or replacing the fuel gauge sender unit or its electrical connections.
