243 complaintsBrakes that feel soft or grab, grinding, ABS and stability control faults.What to check before you buy
Half of the owners who gave a mileage had the problem by about 56,000 miles.
What to check before you buy
- The pedal should feel firm and the car should stop straight without pulling, grinding or a pulsing pedal.
- The ABS and stability control lights should go out after startup and stay out.
- Look through the wheels at the rotors. A deep lip on the edge means brakes are due soon, which is a fair thing to negotiate on.

Engine and cooling
87 complaintsStalling, misfires, oil consumption, leaks, overheating and engine failure.What to check before you buy
Half of the owners who gave a mileage had the problem by about 56,000 miles.
What to check before you buy
- Ask the seller not to warm the car up, and start it cold. Listen for ticking, knocking or a rough idle in the first minute.
- Pull the oil dipstick and the oil cap. Low oil, a gasoline smell or a milky film on the cap are reasons to walk away or get an inspection.
- Plug in an OBD2 scanner. Stored or pending codes matter, and so do readiness monitors that show "not ready", which usually means the codes were cleared right before the sale.
- Ask for oil change records. A gap in the records on a model known for engine complaints is a negotiating point at minimum.
