3 Tail Light Switch problem of the 2015 GMC Sierra 1500

Failure Date: 01/04/2019

The bulbs in the tail lights corrode in place due to excess road grime (salt, sand, etc. ) being splashed up on them. This causes them to burn out prematurely and removal is impossible due to the corrosion of the bulb into the socket. This results in having to replace the entire wiring harness. According to my local GMC dealership (west herr), this is a common problem that gm isn't covering. So, I had to pay for a new wiring harness out of pocket in order to replace one of the tail light bulbs.

4 Tail Light Switch problem of the 2006 GMC Sierra 1500

Failure Date: 11/18/2014

I have had to replace the tail light lenses several times because the tab that secures the lenses to the vehicle breaks and the result is lights just hanging on the truck by the electrical cords. I have the same problem involving my other vehicles in the past made by GMC namely a second family GMC sierra that was made in the year 2004, and a Chevrolet silverado. The electrical lighting on the dashboard has been malfunctioning for a long time. I noticed the malfunction during the first year I bought the truck. I have had to replace electrical switch in the air conditioning/heating the mechanic told me that the wiring is heating up and causing the short to the switch. The new switch has shorted out just like he said it would. I have a notification that my airbag needs servicing. There has been no accident involved to cause this issue. I bought this vehicle new and have been the primary driver since 2006 when I bought the vehicle.

6 Tail Light Switch problem of the 2006 GMC Sierra 1500

Failure Date: 10/15/2010

Rear tail light assembly (both) connection tabs which hold assembly in place fail for no reason allowing light assemble to fall out. Have replaced the rear tail light assemblies three times. First light assembly fell out at 8 months age (approx 20,000 miles), returned to dealer they advised assembly must have been damaged no warranty repair. Replaced both with after-market assemblies, 18 months later rear light assembly connection tabs failed. Replaced with dealer supplied parts (approx 75,000 miles). Now about 18 months later rear light assembly is failing again (109,000 miles). Possible cause is that plastic tabs do not secure light assemble in place, allowing normal use and vibration to cause connection tab to fail.
