A significant number of owners report critical engine failures, including seizing and complete breakdown, often at very low mileage. This is compounded by a major recall (21V301000) concerning improperly heat-treated piston oil rings. Estimated repair cost: $3,000 - $7,000+.

Powertrain/Transmission Issues

Complaints indicate issues with the powertrain, including transmission problems leading to stalling and inability to accelerate. This is particularly concerning given the vehicle uses a Continuously Variable Transmission (CVT). Estimated repair cost: $1,500 - $4,000.

Steering System Problems

Reports of steering issues include stiffness, wandering, and sudden jerking, impacting driver control. These issues often appear early in the vehicle's life. Estimated repair cost: $500 - $1,500.

Exterior Lighting Malfunctions

Some owners have reported issues with exterior lighting, including low beam performance and high beam failure, affecting nighttime visibility. Estimated repair cost: $100 - $500.
