NHTSA complaint #11115671, filed 2018-08, 2,990 miles“Passenger tail light kept getting moisture in it causing it to stop working. Local Dealer,GM,Chevrolet and 3rd party show sold out or discontinued. I have a vehicle I am paying for that I can't drive or risk getting a ticket or rear ended everytime I go to work. Item is on backorder with no date for deliveries to start.”
NHTSA complaint #11592277, filed 2024-06“My drivers side quarter panel taillight has stopped working due to moisture in the light (no visible breakage on light), this was in January. This part is on continuous backorder with no ETA of coming back in stock. The light is an LED and therefore cannot replace just the bulb. I travel for work and drive through large cities and have no left turn signal or brake light which is extremally dangerous.”
NHTSA complaint #11587638, filed 2024-05“Rear taillight has moisture inside which can cause an electrical shortage. Upon Google search, there are tons of other 2018 Traverses with the same issue. I contacted the dealership about a GM service bulletin about the same issue but they stated we would have to pay out of pocket for this issue.”
NHTSA complaint #11487516, filed 2022-10“The tail light is collecting moisture out of nowhere. Went to the dealer to get the item looked at, was told that it was not covered under the warranty. The price to repair will be almost 1300 to replace, this is crazy. GM needs to do something about this. The moisture in the light is a potential for all the electrical wires to burnout.”
