2004 HYUNDAI SONATA Power Train Problems

UNKNOWN, I recently purchased it from a dealership in Lemon Grove Cailfornia. Ever since I bought it,it has never had a catalytic converter and only one muffler. It is a 2.7L motor DOHC and requires 2 catalytic converters and dual exhaust due to the double overhead cam. It has cause motor oil into my engine block and has coughed my heater core. Also blown head gasket. I have hired certified ASE mechanics to replace parts and then I run into another problem.

TL* THE CONTACT OWNS A 2004 HYUNDAI SONATA. WHEN THE VEHICLE WAS SHIFTED INTO DRIVE, IT ACCELERATED ON ITS OWN. THE CONTACT HAD TO TAP THE ACCELERATOR PEDAL A FEW TIMES OR SHIFT INTO PARK FOR THE VEHICLE TO OPERATE NORMALLY. THERE WERE NO WARNING INDICATORS ILLUMINATED. THE DEALER AND MANUFACTURER WERE NOT CONTACTED. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE FAILURE MILEAGE WAS 215,000.

SUSPENSION FAILURE JULY 2016-BOTH ENGINE MOUNTS AND LOWER CONTROL ARMS FAILED. REPLACED 2016 JULY. APRIL 2017 BOTH ENGINE MOUNTS AND LOWER CONTROL ARMS FAILED AGAIN.

SUSPENSION FEELS LOSE IN ADDITION THERE ARE NOISES AS IF BOLTS ARE BROKEN. PER A RECALL SEARCH CAMPAIGN 089 IS OPEN MEANING UNDER BODY ISN'T COATED. UPON FURTHER READING OF THE CAMPAIGN SUSPENSION FAILURE CAN OCCUR AND OTHER ISSUES. UNSURE IF ALL RELATED,BUT THE BRAKE LIGHTS,AND JERKING OCCURRED THE SAME TIME AS SUSPENSION FAILED,WHICH WAS...

THE CAR WAS PARKED IN A RESIDENTIAL PARKING AREA. IT HAD BEEN BACKED INTO THE SPACE. AFTER STARTING THE CAR AND PUTTING THE TRANSMISSION IN DRIVE, THE CAR ACCELERATED UNCONTROLLABLY. THIS OCCURRED SO QUICKLY THE DRIVER WAS UNABLE TO CONTROL THE VEHICLE. BRAKES DID NOT STOP THE VEHICLE. IT APPEARED THAT THE ACCELERATOR WAS STUCK. THE VEHICLE HIT A CAR IN THE NEXT ROW OF CARS. BECAUSE OF RAIN, THE CAR THEN SKIDDED 180 DEGREES AND STRUCK TWO CARS IN THE SAME LINE OF CARS FROM WHICH IT HAD DEPARTED. ONLY AT THIS TIME BY TURNING GETTING THE CAR OUT OF GEAR AND TURNING THE KEY COULD THE CAR BE STOPPED. THE DRIVER BELIEVES THIS WAS THE RESULT OF EITHER A THE ACCELERATOR STICKING ON ITS OWN OR A THICK RUBBER WINTER MAT SLID UP AND JAMMED THE ACCELERATOR. *TR
