Example complaints

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

“Electrical fuses tend to cause electrical shorts, with A/C coming on and off at any given time, often when I hit speed bumps. The lights can be caused by this as well hitting the simple right corner turn can pop the light right out. I have repeatedly told them that it needs better shocks. I have replaced the lights both front and back at a very minimum of 12 times a year. That's ridiculous in my eyes.it should be smarter than that!!!!”

“I was on my way to school, the car began making a grinding noise, as I moved to the shoulder it died and the steering wheel locked up, the radio cut off, the horn stayed on, all the wipers went full force and the doors locked. When I finally kicked the door open I went to the front of the vehicle and opened the good. I began so smell burning plastic and went to the driver side again. When I got there, there were flaming drips coming from under the panels. I attempted to put them out but it was futile. I removed myself from the situation and called fire rescue. …”

“When I start my car and put it in drive it shows reverse on the screen or nothing at all. Then my car will back up instead of going forward. I almost got into an accident a few times because of this problem. This problem has happened to me more than once. The air tubes in the engine already have cracks in them likely because a cheap material was used to produce them, this is very dangerous because it can lead to engine fires in many of these vehicles. In addition, something seems to be already wrong with my transmission and the car is not even that old.”

“I am original owner since feb 09 (manf 12/08) and its now 7 yrs old and reqs new battery. Lifting up floor mat to remove old battery I noticed sticky red oily substance (unkown source but now suspect battery vapor condensation) around top of compartment (mostly where holddown bracket connects). Removing the battery then exposed corroded floor paint from battery acid. In attempting to clean up the mess, I had to remove the battery vent tube exiting the floor. This tube had a spider nest inside about 2 from opening. Wd40 did not penetrate nests end seals & had to extract spider & nest manually. …”
