NHTSA 5-Star Safety Rating
Engine-related complaints dominate what 2024 GMC Yukon owners report, making up the clear majority of filings for this model year. The most common theme is unexpected engine shutdown or loss of propulsion while driving, including at highway speeds and while towing, owners describe the engine appearing to rev normally while the vehicle fails to accelerate or simply stalls out. Some report this happening multiple times in the same vehicle. A secondary cluster involves engine ticking noises and white smoke from the exhaust, present in both cold and warm conditions. A handful of owners also describe broader powertrain behavior, including a "Conditions not Available to Change Gear" message appearing alongside stalling events. A smaller number of reports mention electrical irregularities, things like intermittent start-button response and the engine cranking but not fully turning over, though these appear less frequently than the engine shutdown complaints.

By System
The 2024 GMC Yukon has 4 recalls, with three rated at the highest severity level, including an engine defect on 6.2L V8 models where internal components can fail and cause the engine to shut down without warning.
On 6.2L V8 models, the connecting rod or crankshaft can develop damage that leads to sudden engine failure while driving, raising the risk of a crash. A separate issue affects Yukons equipped with a 6-cylinder diesel engine: an incorrect fuel tank may have been installed that can leak fuel in a rollover, creating a fire risk. There is also a transfer case concern on four-wheel and all-wheel drive models where the front or rear wheels can lock up unexpectedly, which can cause a loss of vehicle control. On the brake side, a software fault in the electronic brake control module can prevent a warning light from appearing when brake fluid drops to a low level, leaving the driver unaware that braking performance has been reduced.
