This page combines three types of NHTSA data: recall campaigns (official manufacturer or government actions), owner complaints (unverified consumer reports), and crash test ratings (where available). A vehicle with many complaints is not necessarily less reliable — complaint volume correlates with sales volume and vehicle age. Recalls indicate identified defects, not overall quality. To compare this model year with others, use the year navigation in the sidebar or return to the model overview page.

The headlight repair has been made but now the tail and park lights work intermittently. Most of the time not working but occasionally they will come on in colder weather. I think the problem is still in the Lighting control module. First appearance was last summer and has gotten worse. No other symptoms. Hazard ,turn signals, and brake lights all still work properly. Just no tail or park lights.

Steering of vehicle has become progressively more difficult. The steering wheel is very difficult to turn. Not being able to rapidly turn wheel places driver at risk to avoid any potential collision.

While driving, I came to a stop light and suddenly, the car idled high and lurched forward while my foot was on the brake, luckily, I was stopped well away from the vehicle in front of me. The car idled high and seemed to have a mind of it's own. I took the back roads home and backed into our garage. The car smelled hot, and I though I had smoked my brakes, trying to keep control of it. Later that night, I told my husband about the car's actions and he did not believe me, though my daughter who was with me at the time confirmed that the car had indeed accelerated on it's own. My husband started the car and it did idle high and get hot once again, although only parked with no one in it. He thought he knew what the problem was and we turned off the car and closed the hood and went inside to order the part. A few minutes later, we heard a couple popping noises and I opened the door that led into the garage from the basement. Smoke was coming into the house and my husband said that a flame shot over my head. The car had caught on fire under the closed hood. We called the fire department, but by the time they arrived, a good portion of the basement was on fire. The house was a total loss. My husband though that the pvc elbow under the hood was sticking closed, so that is the part we were going to order. Unsure, if that was the real cause or not. The car did not have any warning lights or any other indications of a problem before this incident.
