2020 Gmc Yukon problems
The Chevrolet Tahoe, and its badge-engineered GMC Yukon counterpart, are full-size SUVs and other trucks from General Motors, offered since 1994 and 1991, respectively. Since 1982, Chevrolet and GMC sold two different-sized SUVs under their "Blazer" and "Jimmy" nameplates, by introducing the smaller S-10 Blazer and GMC S-15 Jimmy for the 1983 model year, below the full-size Blazer and Jimmy models. This situation lasted into the early 1990s. GMC first rebadged the full-size Jimmy as the "Yukon" in 1991. Chevrolet however waited until 1994, when they rebadged the redesigned mid-size S-10 Blazer the "new Blazer," while renaming the full-size Blazer as the "Tahoe." The name Tahoe refers to the rugged and scenic area surrounding Lake Tahoe in the western United States, and was originally used as a trim level on S-10 models. The name Yukon refers to the Yukon territory of northern Canada.
For the 1995 model year, the Tahoe and Yukon gained a new, longer four-door model, slotting in size between the two-door models and the longer-wheelbase Chevrolet/GMC Suburbans.
The Tahoe is sold in North America, parts of Asia such as the Philippines, and the Middle East, plus other countries including Bolivia, Chile, Peru, Colombia, Ecuador, and Angola as a left-hand-drive vehicle. The Yukon is only sold in North America and the Middle East.
The Chevrolet Tahoe and GMC Yukon are part of General Motors' full-size SUV family and are differentiated from the similar Chevrolet Suburban and GMC Yukon XL primarily by the length of the passenger and cargo area behind the C-pillar. An upscale trim GMC Denali sub-model joined the Yukon lineup as the top-of-the-line trim for the 1999 model year; the Cadillac Escalade is a closely related upscale version sharing the same platform. The Denali is available on both standard and XL versions.
The Tahoe has regularly been the best-selling full-size SUV in the United States, frequently outselling its competition by two to one.

Common 2020 Gmc Yukon problems
The 2020 GMC Yukon, like any vehicle, has its fair share of common problems that owners have reported. These issues, while not necessarily major, can affect the overall ownership experience and may require attention to maintain the vehicle's performance and longevity.
One of the most frequently reported problems with the 2020 GMC Yukon is excessive brake wear. This issue typically arises around 15,000 miles and is attributed to the weight of the Yukon, which can cause the front brake pads to wear down faster. Replacing the brake pads costs around $350, while new rotors can add an additional $650 to the repair cost.
Another problem that some 2020 GMC Yukon owners have experienced is delayed gear changes. This issue tends to appear around 2,500 miles and can be addressed with software updates for the transmission control module, which improve performance. Most dealerships install these updates for free, while others may charge around $100.
Noise from inside the doors is another issue that some 2020 GMC Yukon owners have reported. This problem typically occurs within the first 20,000 miles and is caused by clips that may come loose in the door, allowing things to rattle around. Fixing the problem costs around $250, depending on local labor rates.
In addition to these issues, the 2020 GMC Yukon has also had three recalls, which is average for a large SUV from the same year. The most serious recall covers the pressure regulator on the fuel pump, which may be missing, and GMC will replace the parts on affected models for free. Other recalls include tires and software errors, which GMC will also fix for free on affected models.
While these issues may seem concerning, it is important to note that the 2020 GMC Yukon has relatively minor problems compared to many competitors, leading to lower repair costs. A well-maintained 2020 GMC Yukon can last around 250,000 miles, which is slightly shorter than the long-lasting Toyota Sequoia. Regular annual maintenance costs are similar to other full-size SUVs, according to data provided by Repair Pal, at $687 per year.

POWER TRAIN PROBLEM
- Date Of Incident: 2024-05-20
- VIN: 1GKS1BKC1LR
- Components: POWER TRAIN
- Summary: Shortly after the warranty expired my torque converter went out and damaged the transmission. After speaking with several transmission shops this is a known problem with this vehicle! The torque converter and transmission are poorly made, and no matter if you get all of your services this will still happen to you! This should be a recall on this vehicle. Less than 4 years old and I am having to spend over $5,000 to replace a transmission. The vehicle just hit 100,000 miles. If this is a known issue with this vehicle why has it not been recalled? The dealership tried to tell me I just needed battery cables replaced. I decided to get a second and third opinion and as I suspected the transmission is gone. There were NO warning lights, the car just suddenly started not wanting to change gears while driving. At the red light it jumped and wouldn’t move which made the car behind me almost hit me. There were no other symptoms until the gears started not wanting to change. No noises, smells, or any indication that something was wrong. The vehicle is now at a transmission shop awaiting repair. This needs to be a recall if this is a known issue.

SEAT BELTS PROBLEM
- Date Of Incident: 2020-06-21
- VIN: 1GKS2BKC7LR
- Components: SEAT BELTS
- Summary: THE RENTED 2020 TAHOE WAS STATIONARY. A PASSENGER SITTING IN THE LEFT THIRD ROW SEAT BECAME STUCK IN THE SEAT BELT. SHE WAS UNABLE TO OPEN THE SEATBELT CLASP AS IT GOT STUCK AND FAILED TO UNLATCH. THE MORE THE PASSENGER STRUGGLED TO UNLATCH THE SEATBELT, THE PROGRESSIVELY TIGHTER IT BECAME. PASSENGER COULD NOT DISENGAGE THE SEATBELT CLASP BY PRESSING THE TINY RED BUTTON. THREE OTHER PASSENGERS TRIED TO RELEASE THE SEATBELT AND COULD NOT. PASSENGER WAS TRAPPED WITH TIGHT SEAT BELT HOLDING HER IN. OTHER PASSENGERS CALLED EMERGENCY PERSONNEL WHO ALSO COULD NOT RELEASE THE EVER TIGHTENING SEAT BELT. PASSENGER WAS RELEASED WHEN THE RANGER CUT THE SEAT BELT WITH A SEATBELT CUTTING EMERGENCY TOOL. IT WAS A VERY SCARY AND DANGEROUS EXPERIENCE. LATER, SOME OF OUR GUESTS FIGURED OUT THAT YOU HAVE TO PRESS THE TINY RED BUTTON ON THE LEFT LATCH WITH A PIECE OF THE RIGHT BUCKLE. A PASSENGER SHOULD BE ABLE TO RELEASE THE SEATBELT BY DEPRESSING THE RED BUTTON. A PASSENGER CANNOT EVEN REACH THE BUTTON FROM THE SEATED POSITION AS THE BUTTON IS TINY AND CANNOT ACCOMMODATE AN ADULT FINGER TO DEPRESS IT. THIS IS THE WORST EXAMPLE OF ENGINEERING I HAVE EVER EXPERIENCED. I AM FRANKLY AMAZED THAT THIS DESIGN PASSED ANY SAFETY TESTS. PLEASE ADDRESS THE ISSUE BEFORE SOMEONE IS HURT OR KILLED BY BEING TRAPPED IN THE VEHICLE AND UNABLE TO ESCAPE. *TR

- Remedy: GM will notify owners, and dealers will inspect the tires, replacing them as necessary, free of charge. The recall began March 22, 2021. Owners may contact GMC customer service at 1-888-988-7267, Buick customer service at 1-866-608-8080, Chevrolet customer service at 1-800-222-1020 or Cadillac customer service at 1-800-458-8006.

If a wheel-speed sensor fails, while the vehicle is traveling between 41 and 60 mph in four-wheel or automatic mode, the Electronic-Brake Control Module (EBCM) software may activate the driveline-protection system.
- Consequence: Unintended activation of the driveline-protection system will cause unintended braking on the wheel on the opposite side of the failed sensor, causing the vehicle to pull to one side unexpectedly, increasing the risk of a crash.
