Summary

The 2023 GMC Yukon, while offering a comfortable and spacious ride, has some potential issues to watch out for. Engine-related problems, particularly AFM/DFM lifter failure, can be severe and costly. Transmission issues like harsh shifting and slipping are also fairly common complaints. Electrical glitches, especially with the infotainment system, can be annoying. Suspension issues mainly affect models equipped with the air ride or magnetic ride control, and these can be expensive to fix. While not every Yukon will experience these problems, being aware of them can help potential buyers make an informed decision and properly inspect the vehicle. The severity of these issues ranges from minor annoyances to major mechanical failures, and the cost to repair can vary significantly depending on the problem and the extent of the damage.
