Example complaints

“Started and drove vehicle approx. 1 mile in 20 degree weather when I began to smell an extremely strong raw gasoline odor. The passenger compartment was inundated with the odor. I checked for leaks but did not see any(it was at night). I slowly drove home with my passenger-side windows open. Haven't driven the vehicle since....”
NHTSA complaint #10494578, filed 2013-01, 75,000 miles“We purchased this car new and maintained it according to the manufacturer's maintenance schedule. However, around 75,000 miles the head gaskets started leaking. After each use of the car, oil would leak onto the exhaust manifold and produce a burnt oil smell in the garage; not good. The leak remained limited and our service technician (aaa-approved), advised us to not make any repairs right away, but to monitor the leak. The leaking became progressively worse and affected both the left and right side of the boxer cylinder heads. …”
NHTSA complaint #10723665, filed 2015-06, 90,000 miles“We were driving on the interstate traveling about 70 MPH when my husband noticed the back window had a greasy film that the wiper only made worse. We pulled off the highway to a gas station to take a look and noticed smoke billowing from the hood. After waiting a few minutes he raised the hood to more smoke. Having just had an oil change two days prior, I recalled that the service person mentioned slight transmission and oil leaks that were not major concerns and the car was safe to drive and could be addressed later. …”
NHTSA complaint #10640252, filed 2014-09, 111,969 miles“As I was driving the check engine light came on for the first time - it is now on continuously due to fuel cap. I pulled over at a service station only to realize my oil was next to empty. I promptly filled and continued the final half hour to my destination. Upon arrival I inspected the engine from under the hood & below the car. It was at this time I noticed build up and fluid around both head gaskets. Initially there was oil residue only, now, 18 months later I have coolant and oil leakage & cannot afford to spend the $1800 I have been quoted to replace the head gaskets. …”
NHTSA complaint #10587646, filed 2014-05, 138,000 miles“When ambient air temperature is cold (below about 20-30 f), the vehicle gives off a strong gasoline smell. This is caused by the fuel rail contracting to the point that some fuel is sprayed onto the engine compartment. Obviously, this is a fire risk.”
