ENGINE ABRUPTLY STOPS AND I HAVE A 3 SECOND STALL, THEN THE CAR RESUMES NORMAL OPERATION. COULD BE A REAL SERIOUS ACCIDENT WITHOUT WARNING. THIS HAPPENED IN MOTION ON A HIGHWAY FROM A STOP LIGHT OR STOP SIGN OR PULLING OUT ONTO TRAFFIC.
TRANSMISSION UPSHIFT AND DOWNSHIFT TIMING IS WEIRD. PRESS ACCELERATOR TO GET MORE POWER TO PASS ANY VEHICLE ON THE ROAD AND TRANSMISSION VERY UNTIMELY UPSHIFT INTO HIGHER GEAR REDUCING THE POWER TO WHEELS. CREATES A DANGEROUS SITUATION SINCE LACK OF POWER REQUIRES PRESSING THE ACCELERATOR EVEN HARDER. ENGINE REACTS BY DOWNSHIFTING BUT POWER COMES TO WHEELS FEW SECONDS LATER AND OTHER CARS ON ROAD ALREADY CLOSE IN AND START HONKING.
Complaints are unverified consumer reports submitted to NHTSA. A high complaint count may reflect vehicle popularity, not defect severity. Data sourced from NHTSA public records.
