ECM ISSUES. CAR HAD ECM PROBLEM AND LOST POWER. WENT INTO THE DEALER, AND THEY SAID THEY REPAIRED IT. DIDN'T EVEN MAKE IT HOME FROM THE DEALER AND IT HAPPENED AGAIN. BACK TO DEALER AND THEY SAID AGAIN IT WAS REPAIRED. CAR HAD 10,000 MILES ON IT AT THE TIME. LESS THAN 3,000 MILES LATER, IT HAPPENED AGAIN - CAR COMPLETELY SHUT OFF ON THE HIGHWAY. COMPLETE LOSS OF POWER. DEALER CLAIMED IT WAS THE SAME PROBLEM AND "FIXED" IT WITH A SOFTWARE UPDATE. NOW SCARED TO DRIVE IT - CONSIDERING LEMON LAW? THREE PROBLEMS IN 6 MONTHS ON A BRAND NEW CAR, AND S…

EVERY TIME I RELEASE THE BRAKE PEDAL AFTER SITTING AT A LONG RED LIGHT THE CAR SHAKES AND SHUDDERS, SOMETIMES REALLY HARD, AND SOUNDS LIKE IT'S CHOKING FOR A FEW MOMENTS BEFORE I AM ABLE TO ACCELERATE. IT SOUNDS AND FEELS AND ACTS AS THOUGH IT IS GOING TO STALL BUT IT HAS NOT YET. THE EFFECT DOES *NOT* HAPPEN WHEN THE AIR CONDITIONER OR THE VENT ARE BEING USED; ONLY WHEN THOSE ARE OFF. IT VARIES FROM MILD TO REALLY STRONG. IT TOOK MULTIPLE TRIPS TO THE DEALER FOR THEM TO DETERMINE THAT IT IS NORMAL NOT JUST FOR MY CAR BUT FOR ALL 2016 SONATA…

11/18/2016 - I BACKED OUT OF MY DRIVEWAY AND WAS SLOWLY ACCELERATING UP MY RURAL STREET WHEN THE CAR SUDDENLY BRAKE HARD OF ITS OWN ACCORD AND MADE A CLUNKING NOISE.

I WAS DRIVING STRAIGHT AHEAD - NOT TURNING - NO OTHER CARS WERE IN THE VICINITY. 11/21/16 - WHILE DRIVING, THE CAR DROVE SLUGGISHLY (ALMOST LIKE THE PARKING BRAKE WAS ON).

WHILE DRIVING 65MPH AT 10PM ON A THE INTERSTATE, I HEARD A POUND "THUNK" AND THOUGHT I HAD A TIRE ISSUE, SO BEGAN TO STEER TOWARD THE EMERGENCY LANE. I QUICKLY REALIZED I HAD NO POWER TO ACCELERATE, NO POWER STEERING AND THE DASH WAS BLACKED OUT...CAR WAS DEAD. ONLY EVER THING WORKING WAS RADIO, EMERGENCY FLASHERS AND DOME LIGHT. DOOR LOCKS DID NOT EVEN WORK. CALLED FOR ROADSIDE ASSISTANCE AND CAR WAS TOWED. I HAVE NO FURTHER INFORMATION ABOUT THE CAR'S DISPOSITION AS IT WAS A RENTAL. IT WAS TERRIFYING AND COULD HAVE ENDED CATASTROPHICALLY IN S…

WHILE DRIVING I NOTICE THAT THE STEERING WHEEL SEEMS TO STICK SLIGHTLY SO THAT YOU HAVE TO TURN THE WHEEL EITHER LEFT OR RIGHT SLIGHTLY THEN IT RESUMES STEERING PROPERLY FOR FEW SECONDS THEN IT STICKS AGAIN. IT DOESN'T DO IT ALL THE TIME BUT WHEN IT DOES IT MAKES ME THINK THAT THE STEERING WHEEL IS GETTING READY TO LOCK UP. I NOTICE THIS MOSTLY ON HIGHWAYS AND IT REALLY WEARS YOU OUT TRYING TO DRIVE AND WORRYING THAT THE STEERING MIGHT LOCK UP. THIS HAPPENS A LOT.

DRIVING AT HIGHWAY SPEEDS ONCE THE ENGINE IS AT FULL OPERATING TEMPERATURE THERE IS A HARSH SURGE DURING DOWN SHIFTING AT 35 MPH ( ALMOST AS IF I WERE DOWN SHIFTING A MANUAL TRANSMISSION OR HITTING THE BRAKES) THIS CAUSES THE VEHICLE TO SLOW MUCH MORE RAPIDLY THAN EXPECTED CAUSING MY HEAD AND BODY TO MOVE FORWARD IN THE CAR. IT IS EXTREMELY DISTRACTING AND I AM NERVOUS IT WILL CAUSE AN ACCIDENT.

I was driving and then my car jerk every time I tried to go pass 20mph so I took it to the auto zone to get it checked and they hooked a machine that read code p1326 so I took it in to get checked and the mechanic replaced a knock sensor spark plugs and coil pack and for some reason the vehicle still is misfiring on spark plug number 3 it’s getting no fire I’ve bought a new fuel injector that’s still new in the box but now the vehicle is reading code p0193 which is the fuel rail pressure sensor and was told it could possibly be the engine and I…
