Electrical System Issues

Frequent complaints involve **battery drain**, often linked to the tailgate sensor not deactivating the cargo light, leading to premature battery failure. Other electrical gremlins can cause various system malfunctions. Estimated repair cost: $200 - $400.

Owners have reported spontaneous **windshield cracking**, often without significant impact. This has led to class-action lawsuits and is a common and costly repair. Estimated repair cost: $300 - $1,000+.

Engine Oil Consumption

Some 2.4L turbocharged engines exhibit excessive **oil consumption**, potentially exceeding one quart per 1,000 miles. This requires diligent monitoring to prevent engine damage. Estimated repair cost: $500 - $3,000+.

Recalls have addressed potential **fuel pump failures**, which can lead to a loss of power while driving. Estimated repair cost: $400 - $800.
