Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“On initial start, occasionally the car will become inactive while driving (sometimes stalls/sputters & sometimes just doesn't advance even while pressing on the gas pedal). Often the car spontaneously responds within seconds if it has not stalled, but recently now it stalls and sputters, then needs to be restarted. I was pulling out of a parking lot into traffic with safe distance, when the car became dormant and stalled. Luckily, there was a center lane that I could coast into to avoid causing a serious accident. …”
