The 4th generation GMC Yukon (code name K2XX) is an iconic American Full-Size SUV, a technical cousin of the Chevrolet Tahoe/Suburban and the Cadillac Escalade. Positioned as a premium offering between Chevrolet and Cadillac, it is available in standard and extended (Yukon XL) versions. The top-of-the-line Denali trim accounts for a massive share of sales thanks to its exclusive 6.2L V8 and luxurious presentation. Although very robust in its body-on-frame chassis design, this generation has been marred by recurring problems with the cylinder deactivation system (AFM) of the 5.3L V8 and numerous electronic and braking recalls. Note: Unlike the following generation (T1XX, 2021+) which introduced the excellent 3.0L Duramax 6-cylinder diesel, the K2XX generation was only marketed with V8 gasol
The 4th generation GMC Yukon is a vehicle with two faces. If you opt for the standard version equipped with the 5.3L V8, caution is advised: AFM lifter problems are frequent, expensive, and the list of recalls (brakes, steering) is long. On the other hand, the Denali version equipped with the 6.2L V8 is an excellent choice. This engine proves to be significantly more reliable, offers superior driving pleasure, and justifies the purchase of this behemoth. In all cases, demand a clear maintenance history (frequent oil changes) and verify if the brake vacuum pump and steering recalls have been performed. Also, plan a budget for the inevitable replacement of the Magnetic Ride shock absorbers around 100,000 km.
