2018 Gmc Yukon Safety Report

The 2018 GMC Yukon presents a mixed safety picture, with strong crash test performance but notable concerns regarding braking and powertrain reliability based on NHTSA data. The vehicle received an excellent 5-star rating for frontal and side crash tests, contributing to its 4-star overall safety rating. However, its rollover rating is only 3 stars, which is a point of concern for an SUV of this size. A total of 65 complaints have been filed, including 2 crashes and 2 injuries, indicating real-world safety incidents. A significant pattern of complaints revolves around the engine and power train, with 17 complaints for 'ENGINE' and 7 for 'POWER TRAIN', often detailing catastrophic failures like lifter issues, bent pushrods, and complete engine shutdowns while driving. These issues, while not directly linked to a recall for the 2018 model year, are frequently mentioned by owners as known defects by GM, leading to substantial repair costs and potential safety risks due to sudden loss of power. Recall history further highlights braking system vulnerabilities. Three recalls have been issued, all related to the service brakes. Specifically, two recalls address issues with the hydraulic power assist vacuum system, which can lead to decreased brake assist, increased pedal effort, and extended stopping distances, thereby increasing the risk of a crash. Another recall pertains to the antilock/traction control system, where unintended activation of the driveline-protection system can cause unintended braking on one wheel. These recalls directly impact fundamental safety systems and underscore a pattern of brake-related defects that GM has had to address. While the 2018 GMC Yukon performs well in controlled crash tests, the high volume of engine and power train complaints, coupled with multiple brake-related recalls, suggests potential long-term reliability and safety concerns. Owners have reported sudden engine failures at relatively low mileages (e.g., 48,000 to 81,000 miles), leading to loss of power steering and brakes, which are critical safety hazards. The recurring nature of these engine issues, despite the absence of a specific recall for the 2018 model's engine failures, indicates a systemic problem that buyers should be aware of.

Our recommendation: While the 2018 GMC Yukon offers strong crash protection, potential buyers should be aware of significant engine reliability issues and ensure all brake-related recalls have been completed, as these can lead to costly repairs and safety hazards.
