Consumer Description

WHILE DRIVING IN TRAFFIC CAR BEGAN TO JERK AND LOSE SPEED THOUGH THE ENGINE WAS RUNNING. THE CAR STOPPED IN THE MIDDLE OF MOVING TRAFFIC. TRANSMISSION FLUID SPILLED OUT PROFUSELY. TRANSMISSION WAS REPLACED BUT STARTED TO SLIP AGAIN THE SAME DAY I PICKED IT UP AFTER NEW (REMANUFACTURED) TRANSMISSION WAS INSTALLED BY THE HYUNDAI DEALER. PRIOR TO THIS TRANSMISSION ISSUE, THE ALTERNATOR IN MY CAR FAILED WHILE DRIVING IN THE MIDDLE OF MOVING TRAFFIC. THIS COMPLETE TRANSMISSION FAILURE OCCURRED SHORTLY AFTER A NEW ENGINE WAS INSTALLED BECAUSE THE ORIGINAL ENGINE SEIZED AND FAILED PRIOR. ALTERNATOR WAS REPLACED. THE NEWLY INSTALLED ALTERNATOR FAILED AGAIN. A NEW ALTERNATOR WAS ONCE AGAIN INSTALLED. I AM NOW HAVING SIMILAR ELECTRICAL PROBLEMS YET AGAIN AND THERE IS A CURRENT CONCERN THAT THE VEHICLE MAY POSSIBLY STOP SUDDENLY AND HAZARDOUSLY AGAIN WHILE IN MOTION.
