2021 GMC Yukon Problems And Complaints

2021 GMC Yukon User Complaints and Problems

Mechanical Complaints

• Engine- Faulty pushrod lifters in certain batches of engines have caused the engine to fail prematurely with mileages as low as 7,000-miles. Users have experienced random engine stalls and knocking as a precursor to this issue. No recall has been issued on this problem but the automaker has provided owners with “component coverage” extended warranties which cover the repair cost of SUVs that have been sent in with lifter or valve train complaints.
• Service brakes- “Brake system failure” warning has been one issue that has been bothering many owners. The brakes are said to intermittently lose feel and pressure, decreasing braking performance. The ABS, ESC, AEB, and trailer brake warning lights are also said to illuminate when this happens. The issues were later found to be due to faulty brake calibration from the dealership service end and the affected vehicle were fixed under an official recall (NHTSA ID-21V579000)

Electric system complaints

• Infotainment issues- not an officially recognized issue, but many owners have been complaining about the glitches in the infotainment system. Random reboots, wireless connectivity drop, and faulty USB ports are some major issues stated. Firmware reset/update was said to be a temporary fix as users still face these issues intermittently.
• Steering- A few owners have complained about the loss of power steering/ steering assist functionality while on the move on the 2021 Yukon. This was later found to be a software glitch and was fixed under a factory recall (NHTSA ID- 21V455000)

Safety Complaints

• Airbags- Airbags failing to deploy in the event of a crash and the airbag warning light illuminating randomly have been two common complaints registered against the 2021 Yukon. The issue was found to be with a faulty gateway communication module and the issue was resolved through an official recall( NHTSA ID-21V421000)
• Forward collision avoidance system- A handful of owners have been complaining about the forward collision system on the 2021 Yukon being faulty or too intrusive. Failing to autonomously brake in the event of a crash or braking unnecessarily has been the two major issues as stated. A firmware reset was the only plausible fix as the dealers were unable to replicate the issue.

Should you buy a used GMC Yukon?

The GMC Yukon has easily been in the top 3 full-size SUV ladder since its inception and that is something that stays true to this day. Boasting rugged looks, an exciting list of equipment, and outright capability, this full-size SUV is up to anything. 9 recalls for a model year might seem pretty outrageous, but with the automakers packing in all the technology in the book in their vehicles, it is a pretty common affair these days. Also, GM has been quick to address all these issues and has a good track record of great post-sales support, which adds to the entire ownership experience. With all the love this SUV has been getting all these years, we can’t find a reason that should keep you away from buying a used one.
