  5. 05UNKNOWN OR OTHER439
What these mean
ENGINE

Owners report glow plug failures, fuel rail and fuel pressure failures, and injector connector issues that can cause shaking, speed limiting, and loss of exhaust brake. These can lead to repeated dealership visits and expensive repairs.

POWER TRAIN

Complaints include abnormal shaking, stalling, and loss of power while driving, sometimes requiring reflashing. These issues can leave a driver stranded or cause dangerous slowdowns on highways.

ELECTRICAL SYSTEM

Owners describe persistent 'Service Trailer Brake System' warnings and, in at least one case, an unattended vehicle fire. Electrical faults can distract the driver and pose a fire risk.

SERVICE BRAKES

Reports include brake problems while towing, such as difficulty stopping or brake pedal issues on downhill grades. For a truck often used for hauling, brake reliability is critical.

What these mean
ENGINE

Owners report check engine lights, rough running, and even blown engines at relatively low mileage (e.g., 81,000 miles). Engine failure can cost thousands and leave the vehicle undrivable.

POWER TRAIN

Complaints include loss of speed, deceleration, failure to engage gears, and torque converter failure that damages the transmission. These issues can cause sudden loss of power and expensive repairs.

ELECTRICAL SYSTEM

The trailer brake system warning repeatedly appears on the dash, dinging constantly and distracting the driver. This can make it hard to use other features and adds stress while driving.

UNKNOWN OR OTHER

Some owners report transmission-related problems similar to a known recall, such as losing forward gears and almost causing a crash. These vague but serious issues highlight potential safety risks.

In owners' words — ENGINE

“I purchased my 2020 Yukon Denali on July 8, 2024 from Classic Buick GMC in Painesville, Ohio. The check engine light started going on and off a few months after purchasing the vehicle. When I called a mechanic he stated that I should wait until the light is o…”

Buyer analysis

GMC Sierra or GMC Yukon: which should you buy?

The GMC Yukon has far fewer complaints per year (141.7) than the GMC Sierra (434.5), suggesting it may be less troublesome overall. However, both have significant engine and transmission issues, so the difference means the Yukon might require fewer repair visits, but neither is immune to major failures.

Recommendation. If you need a pickup for heavy towing and can tolerate more frequent repairs, the Sierra might suit you, but inspect engine and brakes carefully. If you prioritize fewer complaints and a family SUV, the Yukon is the better choice, but still check for transmission and engine problems.

Key differences

  • The Sierra has over three times as many complaints per year as the Yukon, with engine issues being the most common for both.
  • Sierra owners frequently report brake problems while towing, while Yukon owners more often mention transmission and torque converter failures.
  • Electrical issues in the Sierra include trailer brake warnings and a reported fire, whereas the Yukon's electrical complaints focus on distracting trailer brake warnings.
  • The Yukon has fewer recalls (42) than the Sierra (86), but both have had recalls for fuel system and brake components.
Watch on GMC Sierra
  • Check for glow plug and fuel injector issues, especially on diesel models, by asking for service records and listening for rough running.
  • Test the trailer brake system and look for any warning lights; also inspect for signs of electrical burning or fire damage.
Watch on GMC Yukon
  • Listen for transmission shudder or delayed engagement, and ask if the torque converter or transmission has been replaced.
  • Check for engine roughness or check engine lights, and verify if the vehicle has had any engine repairs or replacements.

Before you buy

  • Obtain a full vehicle history report and all maintenance records, focusing on engine, transmission, and electrical repairs.
  • Have a trusted mechanic perform a pre-purchase inspection, including a scan for stored trouble codes and a test of the trailer brake system.
  • Test drive at highway speeds and during towing if possible, paying attention to shifting, shaking, and braking performance.
  • Verify that all recalls have been addressed by checking the NHTSA website with the VIN.
  • For the Sierra, specifically inspect the glow plugs and fuel system on diesel models; for the Yukon, check the transmission fluid and torque converter operation.
