Here’s a breakdown of common issues and complaints reported by owners of the 2018 Hyundai Tucson, categorized by component and engine/transmission configuration.

The 2018 Hyundai Tucson is a compact SUV that offers a comfortable ride, a user-friendly infotainment system, and good value for the money. However, some owners have reported issues that potential buyers should be aware of. The Tucson offers two engine options: a 2.0L inline-4 producing 164 horsepower and 151 lb-ft of torque, and a 1.6L turbocharged inline-4 producing 175 horsepower and 195 lb-ft of torque. The 2.0L engine is paired with a 6-speed automatic transmission, while the 1.6L turbo engine is paired with a 7-speed dual-clutch transmission (DCT). Some common praises of the 2018 Tucson include its stylish exterior, comfortable seating, and ample cargo space.
