Half of the owners who gave a mileage had the problem by about 11,000 miles. Parts named most: Warnings (30), Automatic emergency braking (26), Adaptive cruise control (18).

What to check before you buy

• Where it is safe, try the adaptive cruise and lane keeping on the test drive and watch for sudden braking or warnings with nothing there.
• Check the windshield in front of the camera and the bumper sensors for cracks, chips or poor repairs.
• Ask whether the windshield has been replaced. The camera has to be recalibrated afterward, and many shops skip it.

Half of the owners who gave a mileage had the problem by about 8,000 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.

• Feel for slipping (revs rise without the car speeding up), shudder at low speed and a delay when you put it in gear.
• Listen for whining, which is a common CVT complaint, and clunks when you go from drive to reverse.
• If it has 4WD or AWD, engage it on the test drive and ask when the transmission and differential fluids were last changed.

• Open and close every door, the hood and the liftgate, and lock and unlock each one.
• Use a paint thickness gauge and compare panels. A panel that reads very differently from the rest has likely been repaired.

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.
