What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
My headlights go on all by itself whenever I start my car now. My climate control also remains lit and causes a battery drain over a period of time. I was very lucky to make it home but now I can only drive during the daytime until I can get my instrument cluster repaired.
There are no covers on the metal parts on the top of the battery located in the trunk of the vehicle, and the mat that comes with the vehicle does not sufficiently cover these metal poles, leaving them vulnerable to catch flame when metal items are in the back of the vehicle.
While driving 25 mph, the instrument cluster became inoperable and the vehicle lost power. The vehicle was able to be driven to the contact's residence. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was 108,000. The vin was unavailable.
It has about 48500 miles. I work close to home. I have already replaced the suspension air bags once and my vehicle is dropping again. I have read that this is a common problem with my vehicle year, make and model. What can I do?
After owning my used car insurance had to replace the cluster. Found out later it was on a recall list.
While driving at 70 mph, the instrument panel lights flickered on and off then failed to illuminate. The vehicle also started to lose power. The vehicle was taken to the dealer where it was diagnosed that the instrument panel cluster needed to be replaced. The vehicle was not repaired.
Tl* the contact owns a 2002 mercedes benz s430. The contact stated that the instrument panel and the high and low beams failed to operate. In addition, the windshield wipers would activate sporadically. The vehicle was not diagnosed or repaired.
Air suspension problems. Driving down the road and front end of my car drops and wheels start to touch car body, cant turn the wheels either (only slightly) the fender gets on the way, car is too low. I pulled over in a little bit car raised up to normal position. Happened more that few times.
