2018 Hyundai Tucson Safety Report

The 2018 Hyundai Tucson presents a mixed safety picture. While it achieved excellent crash test ratings from NHTSA, scoring 5 stars overall, for frontal, and side impacts, with a 4-star rollover rating, its real-world reliability and potential for sudden power loss are significant concerns. The vehicle has accumulated 369 total complaints, with a notable 13 crashes, 8 fires, and 10 injuries reported. A single recall addresses a serious issue: an engine compartment fire risk related to the ABS module, which was expanded to include the 2016-2018 models. This recall, concerning the SERVICE BRAKES, HYDRAULIC:ANTILOCK/TRACTION CONTROL/ELECTRONIC LIMITED SLIP:CONTROL UNIT/MODULE, highlights a critical safety defect that could lead to injury or crash. The most common complaint patterns revolve heavily around the engine and power train. The 'ENGINE' component alone accounts for 136 complaints, with 'POWER TRAIN' adding another 43, and 'POWER TRAIN,ENGINE' contributing 25. Many complaints describe sudden and complete loss of motive power, engine knocking, excessive oil consumption, and catastrophic engine failure, often at highway speeds. These issues, as detailed in several sample complaints, pose a direct risk of high-speed collisions due to unexpected deceleration in traffic. The dual-clutch transmission (DCT) also appears to be a recurring problem, with owners reporting jerking, shaking, and multiple replacements. The recall for the ABS module fire risk is a serious concern, directly linked to potential engine compartment fires. While this recall addresses a specific electrical issue, the overwhelming number of engine-related complaints suggests broader underlying mechanical or design flaws not fully covered by existing recalls. The high incidence of engine failure, often denied warranty coverage by Hyundai, indicates a systemic problem that could leave owners with significant repair costs and an unsafe vehicle. The discrepancy between high crash test scores and numerous real-world complaints about sudden power loss and engine failure warrants careful consideration for potential buyers.

Our recommendation: Prospective buyers should be aware of the significant engine and transmission reliability issues, including a fire recall, despite strong crash test performance. Thoroughly investigate service history, ensure all recalls are addressed, and consider a pre-purchase inspection focusing on engine health and transmission function.
