Failures reported from 30,000 miles to over 180,000 miles; includes seized engines, catastrophic transmission failure, and overheating damage from belt/pump failures.
Interior plastics described as "cheap dollar general plastic toys" that warp and degrade; minimal soundproofing leading to a noisy cabin.
Overheating due to water pump failure (often related to drive belt issues), radiator failures, suspected head gasket issues.
Complete failure of running lights, brake lights, horn, and dome lights; erratic turn signal operation; speaker failures; issues traced to faulty wiring and shorts.
Use of two separate drive belts without automatic tensioners, making replacement and adjustment difficult; inner belt drives alternator and coolant pump, failure can lead to immediate overheating.
