2016 GMC Yukon Owner Comments

problem #6

Yukon SLT V8

  • Automatic transmission
  • 10,437 miles


I have a 2016 Yukon SLT with 10,437 miles. Right brake light doesn’t work, per dealer not covered under the bumper to bumper warranty. They said they would fix for $800.00 really. Did some research and found out they know their lights are faulty. Should have been covered under the bumper to bumper. Fixed it myself for $450.00 because you cannot just replace the brake light itself unless your an electrical guru. So the dealer wanted to charge $800.00 for a unit which I am sure cost them a lot less then $450.00 and charge me $350.00 for labor for a 5 minute fix really.

Yukon SLT 5.4L V8

  • Automatic transmission
  • 80,000 miles

The right tail light went out and it cost $700.00, but because I have an extended warranty it cost me 250.00.

Yukon XL SLE V8

  • Automatic transmission
  • 35,000 miles

This is a known problem with the 2015-2018 Yukon's and quite frankly any GM vehicle with LED taillights.

It is NOT a wiring problem like some people have mentioned here.

It is a defect inside of the tail light therefore a MANUFACTURING DEFECT with how the LED's and circuit board are soldered.

The soldering is poor quality resulting in small cracks in the soldered connections which then leads to a taillight that only works intermittently and eventually stops working completely.

There is a repair process available from private businesses that you can find online using google or Ebay They have the means and experience to open the taillight housing, repair it, then seal the taillight housing back together air tight. After the repair the taillight is once again functional and air tight so water cannot enter the taillight housing.

Average cost is that I have seen is $140 per light. You will need to remove the taillight yourself, pack it then ship it to the business for repair. They usually cover the shipping charge to send it back to you. Most places advertise a 1-2 turn around time.

GM has played dumb to this defect and the dealers have been instructed to play along as well

The ONLY way to get this problem turned into a class action is for a law firm to get involved and the only way that happens is when Yukon owners start making phone calls.

These lamps are a sealed unit and were never designed to be repaired.

Unlike conventional taillights where you could buy and replace the burnt out bulb yourself for under $10 these taillights are designed so that the dealer profits when you have to buy the entire taillight for $700-800.

Except for the reverse bulb socket, the 2015-2018 GMC Yukon tail light is a sealed unit. There are (5) screws on the back side of the lamp, but they only hold the internal cosmetic hardware. Removing the (5) screws will not allow the lamp to be opened. Any attempt to open the unit by trying to separate the front half from the back half will most likely result in cracking the front clear plastic. DO NOT ATTEMPT.

I had to replace the transmission on the Yukon 2 months after I bought it (was covered) and it still runs rough between gears (auto) but, now the brake lights are out (except at top of tailgate) and it appears to be an electrical or computer issue. I have been told it will be expensive to fix. Waiting on the final quote. Pretty pissed off to read about other 2016 Yukon light complaints as well.

  • Automatic transmission
  • 35,500 miles

It is upsetting that as I research online on how to fix this problem. I find that there are many GMC Yukons that have had this issue. Why is there not a recall on these defective taillights that many seem to be having. I of course went to the dealer and was told I was past my 36 warranty. I purchased an extended warranty and low and behold, taillights are not covered. Ugh!!

  • Automatic transmission
  • 56,000 miles

This car only has 58K miles right now and is a 2016. Never been in an accident! Why would the entire LED light be out? Then I started to notice other Yukons on the street with similar issues. The owners would say people tell them its out and then when they take it in, it is not. Well it's a failing led light…what the heck?!! A man in the parking lot told me that my light was out and I told him i know. It goes off and on. He proceeded to tell me that his daughter had same problem with her Yukon and had to have it replaced at nearly $900!!! Why in the heck is GMC not fixing this as this is obvious a design MANUFACTURING issue, so why am I PAYING FOR IT! This is a $70K friggin truck!!!!
