Acceleration & Cruise Control complaints by model year
The contact owns a 2023 Audi A4. The contact stated that while driving at an undisclosed speed, the vehicle independently accelerated. No warning lights were illuminated. The brake pedal was depressed; however, the vehicle failed to stop as needed. The vehicle crossed a busy street and drove down an incline. The vehicle jumped a curb and came to a stop at a nearby hotel parking lot. There was no injury sustained. A Police report was not filed. The vehicle was driven to the residence. The vehicle was later towed to the dealer, where a diagnostic test was performed. The dealer found no failure with the vehicle. The manufacturer was made aware of the failure, and a case was filed. The failure mileage was approximately 30,000.
NHTSA complaint #11750097 — an unverified report by a vehicle owner.
As I was pulling into a parking spot, traveling at a low speed I naturally applied the brakes but the car accelerated instead jumping a concrete curb and hitting a wall. In that moment I realized I had no control of the vehicle. This sudden unintended acceleration was accompanied by a loss of braking. Pressing on the brakes harder did not stop or slow the car. Brake and accelerator failed. The vehicle is available for inspection. Thankfully the car hit a wall, and there was no injury to myself or others. The parking spot is positioned in front of a concrete wall. The problem has not been confirmed by the dealer as of yet. No warning lamps, message or other signs of malfunction were evident.
NHTSA complaint #11702852 — an unverified report by a vehicle owner.
I leased a 2023 Audi A4 with 0 miles. At ~10,000 miles my car automatically shut down electronically I have photo evidence of this. This happened again recently at ~45,000 miles, I almost got into a severe car accident and possibly died. This happened on the highway driving in the left lane. I tried to remedy this situation before and was ignored by Aud's service center. I am scared I can die on the road and am taking in the car for repeat service tomorrow.
NHTSA complaint #11673447 — an unverified report by a vehicle owner.
I have been an Audi A4 owner for more than 10 years. During that time, I have had 2 incidents where I could have easily been killed as well as injured or killed passengers in oncoming vehicles. The latest was this morning on March 23, 2022. The other was nearly 10 years ago. My personal investigation has led me to a conclusion that I have not yet seen anywhere else. In both cases, I am trying to get into a heavy flow of traffic. I know that I will have to "gun it" to get up to speed. For that reason, I have one foot on the accelerator and one on the brake. When traffic opens to where I think it is safe to proceed, I press the accelerator while my foot is still on the brake. In the situation this morning, I intended to execute a sharp right turn into the closest lane of a road with 2-lanes going in that direction. I pressed the accelerator hard while turning the steering wheel. Instead of turning right, the car shot across both lanes of traffic, wiped out a traffic sign and entered the lanes of oncoming traffic. I had zero control. It was only dumb luck that I avoided traffic in both directions (both of which were travelling at roughly 60 mph). Even though I knew about this risk from my earlier incident, I didn't think about it at the time. I realize that my actions send conflicting signals to the car (go/don't go), but the last thing the car should do is propel itself forward with no control on the part of the driver. I don't know if this is limited to Audi or the A4, but I wanted to make my experience public to possibly avoid a serious or fatal accident by someone else. It is very avoidable with proper knowledge and attention. I'd be interested in knowing if you have been notified of any other incidents of this type.
NHTSA complaint #11457955 — an unverified report by a vehicle owner.
My vehicle will disengage forward or drive at times (transmission) unknowingly and as you apply the gas it sometimes will engage and go forward or reverse in a high speed. Stopped at a light or stop sign becomes dangerous as you are not in control of your speed. Or you may be moved into traffic and lose forward or reverse power.

NHTSA complaint #11440644 — an unverified report by a vehicle owner.
The contact owned a 2021 Audi A4. The contact stated that while driving at a low rate of speed through a parking lot, the vehicle independently accelerated and the brake pedal locked. The vehicle accelerated up a hill as the contact was unable to depress the brake pedal; he collided with an electric pole which caused the vehicle to stop. Due to the shock and abruptness of the failure, the contact was uncertain if any warning lights illuminated the instrument panel. The air bags did not deploy upon impact. The contact and no other bystanders were injured as a result of the failure. The police and fire department arrived at the scene and a police report was filed. Due to the failure, the vehicle was towed from the scene to an independent body shop. The dealer nor the manufacturer had yet to be notified of the failure. The vehicle had been destroyed. The failure mileage was approximately 4,000. The VIN was unavailable.
NHTSA complaint #11418441 — an unverified report by a vehicle owner.
ON JANUARY 28, 2019 I WAS DRIVING TO MY MEDICAL APPOINTMENT AT 35 MILES PER HOUR WHEN MY CAR FROZE UP THEN BUCKED AND NOW NO LONGER THE TRANSMISSION WILL NO LONGER ENGAGE. UPON RESEARCH AUDI HAS KNOWN OF THIS TRANSMISSION HAVING SERIOUS FAULTS AND THAT IT WILL BREAK DOWN WITHOUT WARNING. AUDI HAS REFUSED TO DO ANY RECALL ON THESE TRANSMISSIONS, EVEN AFTER A CLASS ACTION THAT WAS SETTLED, AUDI WILL NOT DO ANY RECALL.
NHTSA complaint #11173668 — an unverified report by a vehicle owner.
DRIVING HOME FROM WORK, ALL OF A SUDDEN MY VEHICLE WAS REVVING WHILE IT WAS IDLE AND AT LOW SPEED, MAKING IT VERY DIFFICULT AND DANGEROUS TO STEER THE CAR AND KEEP IT UNDER CONTROL. UPON INSPECTION, IT WAS FOUND THAT THE TIMING CHAIN TENSIONER HAD FAILED AND HAD CAUSED SERIOUS ENGINE DAMAGE, CAUSING THE PISTONS TO FIRE PREMATURELY. PREVIOUSLY THE TENSIONER WAS REPLACED IN 2014 BY AUDI WHEN THE CAR HAD ~50K MILES AND WAS REPORTED AS A "WEAK TENSIONER". MY CAR CURRENTLY HAS 92K MILES. I BELIEVE THAT NO REPLACEMENT TENSIONER SHOULD ONLY LAST 40K MILES AND CAUSE CATASTROPHIC ENGINE FAILURE AND PUT CONSUMERS AT RISK OF NOT BEING ABLE TO CONTROL THEIR CARS.

GAS PEDAL BECAME STUCK WHILE DRIVING ON THE FREEWAY. I WAS ABLE TO PULL TO THE SHOULDER BY PUTTING THE VEHICLE IN NEUTRAL AND TURNING OFF THE VEHICLE. NOT SURE EXACTLY HOW THIS OCCURRED, BUT IT APPEARED THAT THE PEDAL ACCELERATED ON IT'S OWN. I SENT AN EMAIL TO AUDI TO SEE IF THERE WERE ANY INCIDENCES SIMILAR TO THIS. THE INCIDENT OCCURRED ON NOVEMBER 12, 2016.

NHTSA complaint #10749707 — an unverified report by a vehicle owner.
03 AUDI A4 6 SPEED AUTO CVT TRANSMISSION, THIS VEHICLE HAS KNOWN ISSUES WITH SHIFTING FROM 1ST TO 2ND GEAR TOO SOON. WHILE DRIVING THIS VEHICLE FROM A COMPLETE STOP ON AN ON RAMP ON RT 80 I HIT THE GAS AND IT WOULD SHIFT FROM FIRST TO SECOND AND BACK TO FIRST THEN LURCH FORWARD WHILE ROLLING. WHILE THIS IS GOING ON I AM TRYING TO MERGE ON THE HIGHWAY WHICH PUT MY CAR INTO THE RIGHT LANE DOING ABOUT 2 MPH WITH TRAFFIC (WHICH WOULD BE A SAFE DISTANCE IF THIS ISSUE DIDN'T HAPPEN) HAVING TO COME TO AN ABRUPT STOP NOT TO HIT MY CAR. THIS IS AN KNOWN ISSUE WITH THESE TRANSMISSIONS AND THERE IS NO RECALL ON THEM SINCE NEW. I HAVE EXPERIENCED THIS ISSUE NUMEROUS TIME AS MANY OTHERS WITH THIS VEHICLE DOES. THERE ARE NUMEROUS FORUMS WITH CONSUMERS COMPLAINING OF THE SAME ISSUE. THIS NEEDS TO BE ADDRESSED BEFORE SOMEONE GETS HURT.

AS I WAS DRIVING THE GAS PEDAL WENT TO THE FLOOR FULL THROTTLE. I ALMOST HAD AN ACCIDENT. I FINAL GOT THE CAR OVER TO THE ROAD AT A STOP BY PUTTING THE CAR IN NEUTRAL. THE ENGINE REVVED UP AS HIGH AS IT COULD GO. SO I CUT THE CAR OFF THEN CUT IT BACK ON AND IT CONTINUED TO HAVE THE SAME PROBLEM. IT TOOK 3 TIMES OF CUTTING THE CAR OFF AND WAITING A FEW MINUTES BEFORE THE CAR RETURNED TO NORMAL.

NHTSA complaint #10668127 — an unverified report by a vehicle owner.
WAS DRIVING ON FREEWAY FOR A FEW HOURS DURING WHICH CAR WAS RUNNING FINE, AND CAR SUDDENLY LOST POWER JUST AFTER I GOT OFF FREEWAY AND APPROACHED A MOUNTAIN ROAD INCLINE. THERE WAS NO WARNING LIGHT, OR PRIOR SYMPTOMS TO ENGINE FAILURE, IT JUST STOPPED. WITH HELP, I WAS ABLE TO GET CAR OUT OF THE MIDDLE OF THE ROAD AND TO SAFETY. TRIED TO TROUBLESHOOT, USED ENGINE ERROR CODE READER, AND NO FAULT CODES FOUND. PERFORMED BASICS CHECKED FOR POTENTIAL FUEL VAPOR LOCK DUE TO ALTITUDE; CHECKED OIL, COOLANT AND FUEL LEVELS- AND ALL LEVELS WERE OK. BATTERY WAS FUNCTIONING - AS RADIO, LIGHTS WORKED. CAR HAS BEEN CONSISTENTLY SERVICED AND MAINTENANCE WAS CURRENT. CAR WAS TOWED TO NEAREST DEALER, DIAGNOSIS BY DEALER FUEL PUMP FAILURE DUE TO CLOGGED FUEL FILTER. MY ISSUE IS THAT AUDI DOES NOT INDICATE SERVICE MAINTENANCE FOR FUEL FILTER. THERE IS NOT ANY MAINTENANCE RECOMMENDATIONS OR GUIDANCE IN EITHER THE OWNER'S MANUAL OR PUBLISHED LIST OF RECOMMENDED SERVICES TO REPLACE OR CHECK FILER. THERE ALSO WERE NOT ANY WARNING LIGHTS, FAULT CODES OR INDICATIONS TO WATCH FOR. I FEEL THAT IT IS NEGLIGENT OF THE MANUFACTURER TO NOT INDICATE ANY SERVICE INTERVAL TO CHANGE FUEL FILTER IN ORDER TO PREVENT FUEL PUMP FAILURE, AND TO ENSURE THE SAFE OPERATING CONDITIONS OF THE VEHICLE. THE CAR LOST POWER ON A WINDING MOUNTAIN ROAD AND PUT ME AT DANGER WITHOUT WARNING. I AM CURIOUS IF THIS FUEL PUMP INCIDENT COULD BE ASSOCIATED WITH KNOWN FUEL PUMP ISSUES, NHTSA #PE08027. KEY SIDE NOTES, WHILE I AM THE SECOND REGISTERED OWNER, THIS CAR WAS PURCHASED BY MY FATHER WHO WAS THE ORIGINAL OWNER, BUT FOR INSURANCE AND REGISTRATION PURPOSES THE VEHICLE WAS TRANSFERRED OVER TO ME, BUT I HAVE ALL ORIGINAL RECORDS OF THE VEHICLE AND CAN VERIFY ALL MAINTENANCE SERVICES HAVE BEEN PERFORMED.

GAS PEDAL WAS STUCK ON FULL THROTTLE ON MY WAY TO WORK TODAY. PEDAL WAS ALL THE WAY DOWN AND RPM'S WERE RACING AS I WAS PUSHING THE BRAKES AND TRYING TO GET ONTO THE SHOULDER OF THE HIGHWAY. VERY SCARY SITUATION AND I CAME CLOSE TO A COLLISION WITH MULTIPLE CARS TRYING TO GET THE CAR TO A SAFE AREA. I WAS ABLE TO TURN THE IGNITION OFF, BUT THE PEDAL STAYED IN THE DOWN POSITION FOR OVER 2 MINUTES EVEN WITH THE CAR OFF. THIS WAS DEFINITELY NOT A FLOOR MAT ISSUE AND NOTHING WAS BLOCKING THE PEDAL.
NHTSA complaint #10659934 — an unverified report by a vehicle owner.
TRAVELING ON THE FREEWAY AT 60MPH. THE ESP(STABILITY CONTROL) AND EPC LIGHTS CAME ON. 5 SECONDS LATER THE ENGINE SHUTS OFF AND I KEEP ROLLING AT 60MPH BUT DECREASING SPEED. LUCKILY I WAS ON A STRAIGHT AWAY AND THERE WAS NO NEED TO TURN BUT ONCE THE ENGINE TURNED OFF THE STEERING WHEEL WAS HARD TO TURN AND I COULD NOT PULL OVER. THERE WAS AN EXIT AND I WAS ABLE TO STOP ON THE OFF RAMP. AFTER PUTTING THE VEHICLE IN PARK. I TOOK THE KEY OUT THEN, PUT IT BACK ON THE IGNITION AND TRIED TO TURN THE VEHICLE ON. THE VEHICLE WOULD NOT TURN BACK ON. WHEN IT FINALLY TURNED ON THE VEHICLE STALLED BACK OFF AND THE "CHECK ENGINE" LIGHT CAME ON. AFTER SITTING IN THE VEHICLE FOR 5MIN IN OFF. I THEN TURNED THE VEHICLE ON AND IT STARTED OFF. I WENT TO THE DEALERSHIP AND TOLD THEM WHAT HAD HAPPEN THEY TOLD ME THAT IT HAD NEVER HAPPENED BEFORE WITH OTHER AUDI'S BUT THAT IT SOUNDED LIKE IT WAS THE CRANK SHAFT SENSOR. AFTER LOOKING ONLINE AND DOING RESEARCH MANY OTHER AUDI OWNERS HAD THE SAME PROBLEM THEY STATED THAT THE "ENGINE SPEED SENSOR" AKA CRANKSHAFT SENSOR WOULD GO OUT AND THEIR ENGINE WOULD STALL WHILE DRIVING. THIS IS A SAFETY ISSUE! AIRBAGS GO OFF WHEN THE ENGINE SHUTS OFF AND THE STEERING WHEEL IS HARD TO BE TURNED. PLEASE DO SOMETHING ABOUT IT!
NHTSA complaint #10619158 — an unverified report by a vehicle owner.
WHILE DRIVING THROUGH A PARKING LOT, MY 2004 AUDI A4 1.8 CABRIOLET SUDDENLY ACCELERATED FOR NO APPARENT REASON. I WAS ABLE TO SHUT IT DOWN AND CHECKED TO MAKE SURE THE FLOOR MAT WAS NOT INTERFERING WITH THE GAS PEDAL. I RESTARTED THE CAR AND DROVE TO MY NEXT LOCATION WITHOUT INCIDENT. HOWEVER, AFTER LEAVING MY NEXT LOCATION AND PULLING OUT ONTO THE MAIN ROAD THE CAR STARTED ACCELERATING AGAIN AND WAS DIFFICULT TO CONTROL. THE MORE I APPLIED THE BRAKE, THE MORE THE ENGINE RACED. AFRAID OF CAUSING AN ACCIDENT IN RUSH HOUR TRAFFIC, I WAS ABLE TO PULL INTO A PARKING LOT AND TURN OFF THE CAR. THIS ALSO HAPPENED TO ME ABOUT A YEAR AGO, BUT I ASSUMED IT WAS THE CAR MAT BECAUSE IT NEVER HAPPENED AGAIN UNTIL FEBRUARY OF THIS YEAR. AFTER BEING MADE AWARE OF THE TOYOTA PROBLEM, I DECIDED TO RESEARCH A BIT AND HAVE DISCOVERED MINE IS NOT AN ISOLATED AUDI PROBLEM. I'M HONESTLY AFRAID TO DRIVE THE CAR OUT OF CONCERN THIS MAY HAPPEN AGAIN.
