Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“The electrical system goes out and the car will not start, the horn will not work the care claim to run hot when that isn't the case. The window stop working, the engine say that it need checking however when I take it to be service they always says this model has a lot of electrical problems. I have had wires replaced, new starter, new alternator, new motor in the left window. And I have had all this done to fine out that there is electrical issue with this model. I have wasted hundreds when all you had to do is admit there was an issue and submit a recall.”
NHTSA complaint #10616165, filed 2014-07, 98,000 miles“Driving the vehicle went to turn a corner and the entire car died. I lost all steering and electrical in the car. When the vehicle was tried to be restarted that was a very loud clunking noise. Once towed to a mechanic was told the engine had seized up even though there was oil in the vehicle. Was also told this is identical to the problems other vehicles have been recalled for.”
