Owners report sudden oil loss without visible leaks, leading to engine failure or severe damage. Complaints also mention check engine lights, loss of power, and difficulty accelerating. This is critical because engine replacement is costly and can leave you stranded.
Reports include excessive oil consumption tied to electrical warnings, and issues like stalling or difficulty starting after refueling. These problems can affect daily reliability and may be intermittent, making diagnosis tricky.
With 720 complaints, owners describe steering problems that could affect control. While specific symptoms aren't detailed in the sample, the high count suggests a pattern worth investigating during a test drive.
455 complaints involve brake issues. Although sample texts focus on other areas, the volume indicates potential problems with braking performance or durability, which is a major safety concern.
