Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“My X5 has been a fairly reliable vehicle with some quirkiness along the way. I had a crossover pipe to start leaking coolant. The thing to look for is if you open your hood, and look in the center of the engine (from the front), there is a small hole. Coolant will collect and pour out of that hole onto the ground. The fix through Bmw is anywhere from $9000-$10,000.00; if you are going to allow Bmw to replace the part and labor charges with some parts. What happens is over time the seals go back in this part, and the only way to get to it is to open your entire engine, to replace the pipe. …”

NHTSA complaint #10648978, filed 2014-10, 88,000 miles

“The vehicle started smoking from under the hood while driving in town to the post office. Upon parking the vehicle at the post office, it caught fire under the hood and the fire dept. Had to be called to force open the hood to put out the fire. The entire front of the vehicle was damaged in front of the fire wall. The usps moved employees/customers to the rear of the building for precaution of explosion and smoke inhalation of the burning plastic, rubber and related parts. It was fortunate I could quickly park rather than being on the highway.”
