Example complaints

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

“While driving this vehicle on rt 138 in newport ri, I was accelerating and suddenly experienced a complete loss of power and was able to coast the vehicle out of the travel portion of the roadway. Vehicle required a flatbed tow truck to bring it to balise Toyota in warwick ri. Service department informed me that the inverter had failed and that the repair estimate would be approximately $9400. After researching on the internet I found that this was a fairly common problem with the 2006 and 2007 models and that there had been a recall for certain models. …”

NHTSA complaint #10456197, filed 2012-04, 124,000 miles

“While driving on a highway at 65mph, the vehicle suddenly lost all power. I managed to steer car off to side of road, narrowly avoiding accident. The car did restart, but this stalling and power shut off reoccurred once more. Dealership examined car; test drove it; and said nothing was wrong. I indicated that there was a real problem and safety concern. After my prodding, they admintted that there was, in fact, a voluntary recall, but the needed parts were unavailable. It is one thing to postpone treating a car for a voluntary recall when that car has not experienced the problem. …”
