What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
The contact also stated that a month later while driving the sunroof detached from the vehicle. The vehicle was taken to an independent mechanic that replaced the sunroof however, the failure cause was not diagnosed.
Prior to the failure, the contact heard a ticking noise while driving. The contact was temporarily blinded and burned by the deployment. Medical attention was required. The contact was not able to take control of the vehicle and crashed into another vehicle. A police report was filed.
An engine air filter housing to mass air flow sensor seal tear caused the engine to surge and the car to buck forward instead of braking when the brakes were applied. Failure to break resulted in this vehicle rear ending another vehicle. Luckily the vehicle speed was low so no one was injured or killed.
The police issued a ticket for $130 and filed a report. There were no injuries. The vehicle is currently at the dealer for inspection and repair. The failure mileage was 36,000.
An inspection by a certified technician confirmed that the rear subframe rusted from the inside and experienced a complete structural failure. One of the suspension control arms even broke off of the subframe due to rust. The vehicle showed no warning lights or symptoms prior to the incident.
SRS light went on. Restraint malfunction message flashed across screen. Code reader pulls up dealer recall for driver airbag possibly exploding due to build up of pressure. My VIN is not included and dealer will not honor. Stuck with unsafe car or HUGE expense out of pocket.
One was the "(3) OBD SYSTEM MAY CAUSE THE CHECK ENGINE LIGHT TO ILLUMINATE INCORRECTLY; AND (4) THE SPEEDODOMETER MAY BE OUT OF TOLERANCE" This vehicle has had a malfunctioning "CHECK ENGINE LIGHT", that needs to be corrected.
