Open the full vehicle complaint log (all categories)Unknown. This has happened a couple times now. I am driving and the HEV light, engine light and battery light turn on, car won’t brake properly and almost cause me to hit other cars and will shut off on its own on the highway. It will accelerate on its own even when trying to brake. Extremely dangerous.
I HAVE LEASE THIS CAR SINCE 1/16/2019 UNTIL 4/14/19 . START FIRST WITH LOWER THE SPEED AND POWER JUST A LITTLE BIT. THEN 4/14/19 THE CAR LOWER THE SPEED BY ITSELF,START SHAKING UP,LIMP,SHOWS THE ENGINE LIGHT AND THE SPEED CONTROL LIGH IN CONJUNCTION WITH SLIPPERY CONTROL LIGH THEN STAY AT "TEMPORARY ENGINE PROTECTION MODE" LOSSING SPEED AND CANT DRIVE SAFELY. JUST PARK THE CAR AT THE SAFE PARKING LOT TO TOW AT THE NEAREST HYUNDAI DEALER FOR INSPECTION O REPAIR. IT CAN BE DANGEROUS FOR OTHERS DRIVERS. WHEN I GET THE REPORT OF THE ISSUE AND RECEIPT I WILL SUBMIT SOON AS POSSIBLE. IF ANY RECALL HAPPEN.
