problem #4

Jun 052019


  • 55,000 miles
The rear passenger light assembly has failed. No lights within the housing are currently working. The unsafe condition exists when the vehicle is in motion, as it has no running lights, brake lights or turn signals. This appears to be a very common problem for Yukon's of this year, which are still fairly new.

Driving from prescott, AZ to phoenix, AZ with my husband and 3 year old son. We were heading East on sr-69 when we were pulled over. We were informed that our passenger side brake light was non-operational. After inspection it was found that turn signal and hazard lights worked but not break. A repair order was issued. We took it to the GMC dealership and was told the whole tail/brake light housing, wire, and potentially the fuse needed replaced and that it would cost $700. We were also told by the dealership that a they have had several GMC Yukon owners come in with the same issue and that it was a part malfunction that may or may not be covered by out warranty.
