Exterior Lighting Failures (Headlights)

Condensation ingress into headlight assemblies is a frequent issue, leading to bulb and ballast failure. This significantly impairs visibility and can be costly to repair. Estimated repair cost: $300 - $1,000+.

Electrical System Issues

Numerous complaints point to electrical system faults, including intermittent power loss, stalling, and issues with the Generator Control Module (GCM). These can manifest without warning. Estimated repair cost: $200 - $1,500+.

Reports include issues with acceleration and transmission behavior, as well as less frequent but critical concerns like potential timing chain detachment. Estimated repair cost: $500 - $3,000+.

Rear Suspension Toe Link Corrosion

Recalls address rear suspension toe links due to corrosion, which can lead to fracture. This is a safety-critical component that requires inspection and potential replacement. Estimated repair cost: $300 - $800.
