Brake Light problems of the 2017 GMC Yukon

Driver side rear brake light isn't working anymore. 46k miles on a 2017 GMC Yukon.

Brake lights work intermittently. Very dangerous! passenger side brake light, stopped working completely, then came back on.

Intermittent failure of one brake light while moving. Vehicle has only 38000 miles. This appears to be a common complaint (judging by car forums). I understand GMC makes an improved version of this assembly. Given the potential safety issue, this should be a recall.

Both brake lights stopped working at the same time. There is no fuse. Online reports show many people with the same very dangerous, huge safety issue of their brake lights failing. The car 3 years 2 months old.

Passenger brake light is intermittent. Clearly issue with the internal assembly.

Tail and brake light no longer working.

My drivers side brake lights rarely come on. If I hit a bump they come on for a second.

Intermittently defective tail / brake light. Led circuit breaks. Known issue. Dealer wants $800 to fix. .

Rear passenger led brake light failure. Dealer said this is a known failure item so much so that parts are on backorder nation wide.

Drivers side led brake light does not function. Vehicle has 52,000 miles. Known defect yet GMC does not offer repair. Requires $800 light assembly replacement.

Back passenger side brake lighting went out. Originally it would work sometimes and not work others. Not it never works. . . Dealer said earlier years were covered by recall but not 2017. Very expensive to replace and ive had the car 2 years. Crazy.

The GMC Yukon models in all trims, have faulty led strips that cause the brake lights to fail on the left, and right brake light assembly. The frustrating part is it works intermittently, and when it's off a slight tap will momentarily bring it back on for the duration of the jolt. This leads me to believe that it's faulty connection inside the seals brake light assembly. There are thousands of complaints online on owner forums of GMC Yukon's . This is known as the new year models 18-19 are not having the same issue.

Tl the contact owns a 2017 GMC Yukon xl. The contact stated that the brake lights failed to illuminate intermittently. The contact took the vehicle to marvin k brown auto center (located at 1441 camino del rio s, san diego, CA, 619-272-6867) where it was diagnosed that the brake lights needed to be replaced. However, due to the commonality of the failure, the parts were on backorder. The vehicle was not repaired. The manufacturer was not notified. The approximate failure mileage was 64,000.

Right tail/brake light has intermediate problem. Advised dealership, they hit the light with hand and it flashed. GMC is aware that this is a problem. No detection from any of the sensors advising there is a problem with the tail/brake light. This is obviously an issue with GMC Yukons wherein there is a broken wire in the light itself and it is a full unit that cost approximately $650. 00. Prince dealership did not even advise that there is a recall on my vehicle at the time of checking the tail/brake light was warranted.

Drivers side led brake light strip inop. Dealer says its 650 per side plus labor to replace. GMC is aware of issue but will not stand behind there product. They also lie and say it's the first they have heard of this type of failure. This is a safety concern and customer is liable for a ticket that may result from faulty gm parts.

Brake lights are going out without notice.

The led rear brake lights are consistently failing on thousands of these vehicles. Dealer told me they are on back order and are unavailable as they can't keep up with demand. Without a fix, how can I safely drive the car? I have one out, if the other goes out, what is the solution?.

Pulled over by police for malfunctioning lhr brake light. Entire rear lamp assembly must be replaced since it is an integrated circuit board with led lamps. $700 plus installation. Several victims on-line discussion forums.
