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.

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.

My quarter panel taillight has stopped working due to moisture in the light (no visible breakage on light). This part is on continuous backorder with no ETA of coming back in stock. Dealer has ordered part but will not give a loaner car. GM acknowledged backorder but will not give rental reimbursement. I have three children I am to put in this car that does not have a left turn signal or brake light. I feel unsafe driving this car as I may be rear ended but everyone I talk to says they can't do anything. What am I to do.

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.

The right rear quarter panel stop turn signal light started to retain moisture then the turn signal and stop light stopped working all together. the light is an LED and therefore cannot replace just the bulb. I am having no luck finding the correct replacement as any search turns up a part discontinued by Chevrolet.

Both the driver and passenger side rear turning signals accumulate condensation (if conditions permit, liquid water). When the automatic lights are engaged the rear turning signal will blink rapidly (as if the bulb was out). This problem does not occur when the day-time running lights are on. Estimated repair costs are $600 per light, as the entire housing must be replaced rather than just replacing the bulbs when they wear out.

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.

The right rear outside signal light assembly is defective. Shoddy workmanship allowed moisture into the assembly shorting out the LED lighting. The signal, including 4-emergency light stopped functioning. The entire assembly must be replaced. There is not simply a light bulb to change. The replacement cost of over $500 will cause people to not change the assembly thus prolonging the operation of the vehicle in an unsafe manner.

Led tail lamp burned internally. There are no fuses in for any of these lamps in the owners manual. Dealership blamed the non functional light on water damage without having even investigated what was wrong. Chevy's own TSB states moisture normal(01-08-42-001L). I personally removed the lamp after the dealer asked over $900 to replace it, stating moisture damaged it. The dealer never inspected it. It's electronics are burnt!
