Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“While sitting idle my vehicle suddenly went into reduced engine power mode. I was able to get over and pull off the road and shut off the car. 5 minutes later the car started like there was no problem. Over the next few days the rep warning would show up and my car would suddenly lose power. I was crossing the road during one incident. However, when I would shut off the car and restart the check engine light would go away as would the rep warning. After a quick review online it is easy to find hundreds of people who have a similar issue. …”
NHTSA complaint #10725348, filed 2015-06, 179,000 miles“Incorrect speedometer reading. Sometimes reads zero on the highway, sometimes might read 40 or 50 while doing 55 (checked with GPS). Seems to happen more on really hot days, but also seems to be able to happen at any time (though it does not do it all of the time, it has been happening since mid-2006).”
