NHTSA Complaint #10489701 — 2012 HYUNDAI SONATA HYBRID

WHILE SLOWLY MOVING DOWNHILL, ON THE FREEWAY, DURING RUSH HOUR TRAFFIC, I ATTEMPTED TO CHANGE LANES AND ACCELERATED QUICKLY. THE SWITCH FROM HYBRID TO GAS ENGINE INTERFACE ONLY CAUSED THE ENGINE TO REV (INCREASE RPM) WITHOUT ANY GEAR BEING ENGAGED. I QUICKLY LET OFF THE PEDDLE AND DEPRESSED IT AGAIN. IT THEN ENGAGED THE TRANSMISSION, NARROWLY AVERTING AN ACCIDENT. THIS HAS HAPPENED 5-6 TIMES SINCE PURCHASING THIS CAR WHEN TRAVELING SLOWLY AND THEN TRYING TO GET A BURST FROM THE GAS ENGINE. I SPOKE WITH THE DEALERSHIP, AND TOOK IT IN FOR A CHECK PER THEIR RECOMMENDATION. THEY FOUND NOTHING AND COULD NOT REPRODUCE IT, ALTHOUGH THEY DID NOT TRY THE SAME CIRCUMSTANCE. THEY ONLY ATTEMPTED TO STOP AND ACCELERATE AT WHICH I SAID THEY WOULDN'T GET IT TO HAPPEN THAT WAY.
