Frequent issues include infotainment system reboots, power liftgate malfunctions, door lock actuator failures, intermittent power loss, and stalling. Some owners have reported electrical smells and fires related to heated seats. Estimated repair cost: $100 - $1,500.

A critical recall (15V144000) addresses potential failure of the Electric Power Steering (EPS) system due to manufacturing defects in the ECU. Some owners report persistent steering issues even after the recall. Estimated repair cost: $500 - $1,200.

Engine Control Module (ECM)

Water intrusion through aftermarket windshields (recall 18E107000) can damage the ECM, leading to engine stalling. Estimated repair cost: $600 - $1,500.

Some instances of engine failure have been reported, including issues with head gaskets and low oil pressure warnings leading to catastrophic failure. Timing cover oil leaks are also noted. Estimated repair cost: $1,000 - $5,000+.

Complaints exist regarding airbags not deploying as expected in collisions. While not a widespread recall for this specific model year, it's a noted concern. Estimated repair cost: $500 - $2,000+.
