It's a documented issue but not catastrophic. 46 complaints have been filed. Repairs average $1,500 and most owners catch it before it causes a breakdown.
At what mileage does the body typically fail?
Mileage data is limited for this issue. Owners report failures across a wide range, suggesting cause is more about driving conditions and maintenance than mileage alone.
