1993 Hyundai Sonata Engine Problems

Owner-reported complaints naming the engine system, filed with NHTSA

Data refreshed

Engine reportsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

AT DIFFERENT TIMES AND SPEEDS, THE CAR WILL SKIP AT TIMES. SOME TIMES IT SURGES VERY BAD AND CHECK ENGINE LIGHT WILL COME ON. OTHER TIMES THE CAR WILL MISS AND THE CHECK ENGINE LIGHT DOES NOT COME ON. TECHNICANS AT DEALERSHIP CAN NOT FIND TROUBLE CODE FROM CHECK ENGINE LIGHT TO SOLVE PROBLEM. YOU MAY DRIVE 300 MILES WITH NO PROBLEM, AND THEN YOU MAY DRIVE 10 MILES AND IT SURGES AND THE CHECK ENGINE LIGHT COMES NUMEROUS TIMES. THE CAR HAS BEEN SERVICED, TUNED AND FILTERS CHANGED AND DOESN'T HELP THE PROBLEM. I AM AFRAID I WILL GET IN HEAVY TRAFFIC AND STALL COMPLETELY, POSSIBLY CAUSING AN ACCIDENT.
