2020 Acura RDX Engine

Engine judders at 2k rpm around 60 mph. Car has 92k miles with timely documented service maintenance. Took car to the dealership and said there’s a head gasket leak on cylinder 4 and needs to be replaced. Contacted American Honda about the issue and they said they cannot cover the repair cost. They also don’t have the replacement part for the fuel pump recall for a long time as well.

Re: NHTA recall 23V-858 This particular recall has been active since 12-18-2023. I have checked with my local dealership, Scanlon Acura in Ft Myers, FL, to arrange for a repair several times. Each time I have been told that they do not have the part. On Friday, 12-6-2024, a spoke to a service representative at the dealership. He advised me that they did have the part and scheduled an appointment to replace the defective part on Monday, 12-9-2024. When I arrived at the dealership, I was told that they did not have the part. Something is not right here. I suspect that the dealership does not want to replace the part because it is time-consuming, expensive, and represents an action where they do not receive enough compensation. This recall has been active for nearly a year, and NHTSA should intervene to expedite this process in order to prevent possible car crashes and injuries.

The emission light flashes and puts the vehicle in "Limp mode." The speed is drastically reduced and won't exceed 30 mph. Horrify experience. The problem seems related to rain and acceleration. Now the car is towed. No warning before it happens. But the emission light was flashing afterward.

Driving about 75 (local speed limit) from College Station Texas to Plano, Texas over the Easter weekend and vehicle suddenly lost all power, check engine light illuminates, and I have to pull over. After several minutes, light is extinguished. Restarted vehicle and service engine light illuminates (B17). Had not been on before. I drove about 65 the remainder of the trip and took it to the Dealership in town. The incident can not be replicated per the shop. 22K miles.

The contact owns a 2020 Acura RDX. The contact stated that while driving at approximately 70 MPH, the vehicle went into limp mode and experienced unintended deceleration to 5 MPH with the check engine warning light illuminated. The vehicle was towed to the dealer; however, the dealer was unable to duplicate the failure. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was 18,986.

Under heavy acceleration, the vehicle began "bucking" and then lost all power. The check-engine light began flashing. The engine was still running but did not provide power. I Had to pull off the road, shut the engine off and then restart to clear the problem. This has happened twice in two days. The Acura dealer says it is an issue with moisture entering the turbo-charger but did not have any suggestions to correct or prevent this from happening again.

This car has 21,000 miles, while accelerating the car lost power and the engine light came on, almost caused a severe crash with semi truck. There are numerous articles post about this exact same problem with 2019 and 2020 Acura RDX and some information indicates it was due to solvents used in the manufacturing process of the in tank fuel pumps. It is more pronounce in warmer climates and rain. Acura needs to issue a recall before people get killed from this deficiency in their product.

- 2020 Acura RDX Aspec - my 2nd one of this model!!!!! - Tue, 18May2021 - travelling at ~65 mph on the Houston Hardy Toll Road and lost all ability to accelerate and MIL (engine light) came on - I was able to pull over 4 lanes to the right shoulder safely - I turned the car off, waited ~30 seconds and then turned the car back on - I drove to the dealership, Gillman Acura, which is ~21.4 miles, and delivered the car - Gillman Service Rep advised that they were applying the intercooler replacement fix associated with Acura Service Bulletin 20-053 - issued 21Apr2021 - Dealership replaced intercooler, I picked up the car on Thu, 20May2021 - drove ~22 miles home and the very next day, Fri, 21May2021, when i was ~3 blocks from my house, the VSA - vehicle stability assistant light came on - 21May2021 and the car is back at the dealership for repair - The RDX is a rolling death trap and I pray that it doesn't take one or more fatalities and/or serious injuries to Acura owners and/or others before Acura does the right thing - a recall - In Apr2021, I purchased the first 2020 RDX Aspec, VIN: 5J8TC1H6XLL014219, and experience the "limp mode" issue on 4Jul2020 while traveling on I-10 west from Tallahassee to Houston - vehicle had 2.8K miles and experienced limp mode - see NHTSA complaint > 11339164 - Dealership exchanged the first car and now I've experienced "limp mode" with the second car

I PURCHASED A 2020 RDX A SPEC PACKAGE VEHICLE AND ALMOST IMMEDIATELY STARTED EXPERIENCING A HESITATION OR SLIPPING OF THE TRANSMISSION SENSATION. IT IS INTERMITTENT BUT HAPPENS WHEN COMING TO A COMPLETE STOP AND THEN TRYING TO PULL ONTO STREET, FREEWAY OR TRAFFIC FROM A COMPLETE STOP. I HAVE HAD THE VEHICLE INTO THE DEALERSHIP BUT THEY REFUSE TO ACKNOWLEDGE ANYTHING BECAUSE THE MANUFACTURER HAS NOT POSTED ANY VEHICLE PROBLEMS OR RECALLS. THE DEALERSHIP SAYS THERE IS NOTHING WRONG WITH CAR BASED ON THE "COMPUTER CHECKS" RUN ON THE VEHICLE. THE PROBLEM IS BECOMING INCREASINGLY WORSE AND I AM BECOMING CONCERNED ABOUT AN ACCIDENT BECAUSE OF THE HESITATION CAUSED WHEN TRYING TO PULL INTO TRAFFIC.

This is the second complaint I have filed with the NTSB. The transmission in my 2020 Acura RDX feels as if it is slipping. From a complete stop to trying to advance the call forward, the engine will act as if it cannot find first gear and then will "jump". This does not happen all the time but is frequent enough to garner my attention. This problem started immediately after I purchased the car. I have brought it to the attention of the Acura dealer multiple times but the refuse to deal with it because they say the NTSB has not issued any recalls for this particular problem.

FIRST TIME OCCURRENCE; I AM THE FIRST TIME OWNER AND BOUGHT MY CAR NEW. APPROXIMATELY 1 YEAR AND 3 MONTHS OF OWNERSHIP. ATTEMPTED TO MERGE ONTO THE FREEWAY. GOING ABOUT 55 MPH AND ATTEMPTED TO ADVANCE TO 65 MPH. RPMS INCREASED TO ABOUT 4500-5500 BUT NO SPEED INCREASE. VEHICLE MADE A ERVING ENGINE SOUND. FLASHING CHECK ENGINE LIGHT THEM CAME ON AND AGAIN SO SPEED INCREASE WITH PRESSING THE GAS PEDAL. CAR THEN STARTED SLOWING DOWN AS IT WAS NOT RESPONDING TO MY FOOT ON THE GAS. HAD TO MERGE ONTO THE SIDE OF THE ROAD, TURN THE VEHICLE OFF THEN BACK ON.

TL* THE CONTACT OWNS A 2020 ACURA RDX. THE CONTACT STATED THAT WHILE ACCELERATING ABOVE 50 MPH, THE VEHICLE LOSS MOTIVE POWER AND STALLED WITHOUT WARNING. THE CONTACT PULLED OVER AND WAITED FOR SEVERAL MINUTES BEFORE RESTARTING THE VEHICLE AND, THE VEHICLE OPERATED AS INTENDED. NAPLETON'S PALM BEACH ACURA (6870 OKEECHOBEE BLVD, WEST PALM BEACH, FL 33411, (877)363-2817) WAS CONTACTED AND INFORMED OF THE FAILURE. THE CONTACT WAS INFORMED THAT THE VEHICLE NEEDED TO BE DIAGNOSED. THE CONTACT WAS NOTIFIED OF AN UNKNOWN TSB RELATED TO THE FAILURE. THE CONTACT WAS INFORMED TO CALL BACK IN JANUARY 2021 FOR ASSISTANCE. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND WAS INFORMED THAT THE VIN WAS NOT SUBJECTED TO A RECALL. THE MANUFACTURER RECOMMENDED THAT THE VEHICLE BE DIAGNOSED AND THE RESULTS FORWARDED TO A REPRESENTATIVE. THE CONTACT WAS PROVIDED A CASE NUMBER. THE VEHICLE WAS NOT REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 5,300.*DT *TR

AFTER A STOP AT THE VA WELCOME CENTER, I ATTEMPTED TO MERGE INTO TRAFFIC ON I-81 NORTH. THE VEHICLE SUDDENLY LOST POWER AND THE CHECK ENGINE LIGHT CAME ON. I WAS ABLE TO MOVE TO THE SHOULDER AND AVOID BEING REAR ENDED. THE VEHICLE WAS TOWED TO DUNCAN ACURA. THEY DETERMINED MULTIPLE CASES OF SIMILAR MODELS HAD THE SAME COMPLAINT. THIS IS A KNOWN ISSUE THAT HAS THE POTENTIAL FOR LOSS OF LIFE AND SHOULD BE REMEDITED IMMEDIATELY. ONE ONLINE SOURCE SAID ACURA HAS KNOWN OF THIS PROBLEM SINCE 2016.*DT *TR

DRIVING IN THE RAIN, ACCELERATING ONTO A HIGHWAY, OUR 2020 ACURA RDX LOST POWER AND WOULD NOT ACCELERATE. THE CHECK ENGINE LIGHT WAS BLINKING, AND WE WERE FORCED TO PULL OVER. AFTER RESTARTING THE CAR, THE THE CHECK ENGINE LIGHT WAS OFF AND WE WERE ABLE TO DRIVE NORMALLY. THE CAR WAS TAKEN TO THE DEALER ON 10/24/20 BUT THE ISSUE COULD NOT BE REPRODUCED. WE WERE INFORMED THAT ACURA IS AWARE OF THE PROBLEM AND MAY BE WORKING ON A FIX. THE PROBLEM IS ALSO WIDELY REPORTED ON THE ACURAZINE INTERNET FORUM. RESEARCHING THE ISSUE, IT APPEARS TO ONLY HAPPEN DURING RAINY CONDITIONS AND WHEN ACCELERATING.

I RECENTLY LEASED 2020 ACURA RDX BASE MODEL SUV. I HAVE NOTICED FREQUENT UNEXPLAINED DECELERATION WHEN ON HIGHWAY, PROBABLY OCCURS AT LEASED ONCE EVERY TIME I DRIVE AT HIGHWAY SPEEDS. I HAVE CONTACTED ACURA OF PLEASANTON VIA THE SALES ASSOCIATE I HAVE DEALT WITH FOR THE PAST SEVERAL YEARS, DESCRIBED THE PROBLEM. HAVE NOT RECEIVED RESPONSE, AND IT DOES NOT APPEAR THAT A RECALL ON THIS MODEL HAS BEEN ISSUED, SO I AM IS CONTACTING THE COMPANY DIRECTLY. IN RESEARCHING THE ISSUE ONLINE I FIND THERE HAVE BEEN AT LEAST 40 COMPLAINTS TO THE NHTSA REGARDING EXACTLY THE SAME ISSUE. MANY OF THE COMPLAINTS HAVE INCLUDED PRIOR VISITS TO ACURA DEALERS FOR REPAIRS, BUT WHAT WAS DONE DID NOT SOLVE THE PROBLEM. SO APPEARS ACURA IS AWARE OF THE ISSUE ALSO THAT IT COULD BE A SAFETY FACTOR, BASED ON REPORTS IN THE COMPLAINTS. I HAVE NOT HAD AN INSTANCE WHERE SAFETY WAS INVOLVED - YET - BUT I CAN SEE THE POTENTIAL FOR A DANGEROUS SITUATION, WHEN MY RDX DECELERATES, THERE IS NOTHING I CAN DO, THE VEHICLE IS UNRESPONSIVE FOR A PERIOD OF TIME, WHICH COULD LEAD TO AN ACCIDENT. I HAVE RECEIVED MAILINGS FROM A LEGAL GROUP URGING ME TO FILE, THEY INDICATE THAT MY RDX IS SUBJECT THE 'LEMON LAW'. I AM ALSO AWARE FROM SEARCHING THE INTERNET THAT MORE THAN ONE CLASS ACTION SUIT HAS BEEN FILED BY RDX OWNERS WHO HAVE EXPERIENCED THE SAME PROBLEM. I DON'T SEE THE POINT OF TAKING VEHICLE IN FOR SERVICE SINCE OTHERS REPORT THE PROBLEM DOES NOT GET RESOLVED, AND ACURA DOES NOT SEEM TO HAVE SOLUTION FOR DECELERATION ISSUE.

I WAS ACCELERATING TO APPROXIMATELY 55MPH TO PASS A VEHICLE. AS SOON AS I COMPLETED THE PASS,THE ENGINE DECELERATED TO 20 MPH AND THE CHECK ENGINE LIGHT WAS FLASHING. FORTUNATELY FOR US WE WERE ABLE TO GET THE CAR SAFELY OFF OF THE ROAD. WE THEN SHUT THE ENGINE OFF. WAITED ABOUT 5 MINUTES RESTARTED THE ENGINE AND IT RAN FINE THE REST OF THE WAY HOME.

I WANTED TO LET YOU KNOW A FRIGHTENING EXPERIENCE WE HAD WITH THE ACURA RDX ON AUGUST 16TH. MY FAMILY, INCLUDING MY 2 CHILDREN & DOG, WERE DRIVING HOME ON THE EXPRESSWAY IN THE HOV LINE. MY HUSBAND WAS DRIVING THE RDX WE JUST LEASED NOT EVEN A MONTH AGO. HE HAD THE CAR IN CRUISE CONTROL DOING 60 MPH. THE CAR SUDDENLY LOST ACCELERATION AND DESPITE MY HUSBAND TRYING TO HIT THE GAS, THE CAR WOULD NOT GO AND EVENTUALLY LOST POWER AND CAME TO A DEAD STOP IN THE HOV LANE. HE JUST MISSED GETTING HIT BY THE CAR BEHIND HIM. YOU CAN IMAGINE HOW CATASTROPHIC THIS COULD HAVE TURNED OUT. THE MALFUNCTION INDICATOR LIGHT CAME ON. HE TURNED THE CAR OFF AND LET IT COOL AS IT SAID TO IN THE MANUAL. EVENTUALLY AFTER BEING TURNED OFF FOR APPROXIMATELY 5 - 7 MINUTES, HE TURNED THE CAR BACK ON AND IT STARTED. HE DROVE HOME, BUT CLEARLY WE WERE BEYOND SHAKEN.

2020 ACURA RDX WITH APPROX 6,200 MILES. DRIVING FROM PITTSBURGH, PA TO NEW JERSEY. I REACHED NEW JERSEY AFTER DRIVING FROM PITTSBURGH. THERE WAS MODERATE TO HEAVY RAIN SHOWERS DURING THE DRIVE. THE RAIN ENDED PRIOR TO ME ENTERING NEW JERSEY. I EXITED THE JERSEY TURNPIKE FOR THE ON RAMP TO 195 EAST. I WAS GOING APPROXIMATELY 45 MILES MPH WHEN I PRESSED THE GAS PEDAL TO ACCELERATE SO I COULD SAFELY ENTER TRAFFIC. I COULD FEEL THE ENGINE GIVE WAY AS I PRESSED THE PEDAL. THE CAR DECELERATED AND THE CHECK ENGINE LIGHT ILLUMINATED. I PULLED OFF THE HIGHWAY TO THE SIDE OF THE ROAD AND PUT ON THE FLASHERS. I LET THE CAR RUN AT IDLE. THE CHECK ENGINE LITE WENT OFF SO I TRIED TO ACCELERATE THE VEHICLE WITH NO LUCK. THE ENGINE WOULD REV A LITTLE BUT THE CAR WOULD ONLY ACCELERATE TO APPROXIMATELY 25 MPH. I TRIED THIS MULTIPLE TIMES. I WAS NEAR AN EXIT AND THE VEHICLE WAS ABLE TO MOVE AT A SLOW SPEED SO I DROVE APPROXIMATELY 2 MILES TO A FRIEND'S HOUSE. AGAIN, THE VEHICLE WOULD NOT GO OVER 25 MILES AN HOUR. AFTER REACHING MY FRIEND'S HOUSE, I TURNED OFF THE IGNITION. ABOUT 1 HOUR AND 30 MINUTES LATER I TURNED ON THE VEHICLE. THIS SEEMED TO FIX THE PROBLEM AND I WAS ABLE TO CONTINUE HOME WITH NO FURTHER ISSUES. THE CHECK ENGINE LIGHT REMAINED OFF. ACURA LOOKED AT THE CAR BUT THERE WAS NO RECORD OF THE PROBLEM AND THEY COULD NOT DUPLICATE THE ISSUE. NOT SURE IF IT WAS AN ELECTRICAL ISSUE OR AN ENGINE ISSUE.

AFTER DRIVING ON SECONDARY ROADS FOR AN HOUR, I ENTERED A HIGHWAY. I WAS ACCELERATING ON THE ENTRANCE RAMP AND NOTICED A CAR GOING VERY SLOW IN THE SLOW LANE. I PUT ON MY BLINKER, ACCELERATED MORE AND MOVED TO THE MIDDLE LANE OF THE HIGHWAY. THE CAR IMMEDIATELY WENT INTO 'LIMP MODE', LOSING ALL POWER AND THE CHECK ENGINE WAS BLINKING. I COULD NOT PASS THE CAR THAT WAS GOING ABOUT 30 MPH AND HAD TO APPLY MY BRAKES IN THE MIDDLE OF A HIGHWAY AS TRUCKS WERE BEARING DOWN ON ME. THIS WAS TERRIFYING! I WAS ABLE TO PULL OFF TO THE SIDE AND SHUT DOWN THE ENGINE. AFTER 30 SECONDS I RESTARTED THE CAR AND ALL POWER WAS RETURNED WITH NO CHECK ENGINE LIGHT. THE DEALER COULD FIND NO PROBLEM, BUT HONDA NEEDS TO FIX THIS BEFORE SOMEONE GETS KILLED. *TR

WHILE DRIVING DOWN A TWO LANE 55 MPH SPEED LIMIT ROAD, I CAME UPON A CAR THAT HAD STOPPED IN MY LANE AND DIRECTION OF TRAVEL. I SLOWED DOWN, PROBABLY UNDER 30 MPH, AND DECIDED TO GO AROUND THE VEHICLE. I WAS OVER THE CENTER LINE OF THE ROAD AND FLOORED MY ACCELERATOR TO GET AROUND THE STOPPED VEHICLE AS QUICKLY AS POSSIBLE. RIGHT AFTER THIS MY CAR LOST POWER AND THE MIL LIGHT CAME ON. I CAN NOT REMEMBER IF IT WAS FLASHING OR ON STEADY. MY CAR'S ENGINE WAS RUNNING BUT HAD NO POWER SO I PULLED OFF THE ROAD AND TURNED IT OFF. AFTER ABOUT A MINUTE, I RESTARTED MY CAR, THE MIL LIGHT WAS OFF AND MY CAR RAN FINE. I HAVE A CODE READER. WHEN I GOT HOME THE FIRST THING I DID WAS ATTACH THE CODE READER AND FOUND THAT THERE WAS NO CODE(S) STORED. I WAS OF THE BELIEF THAT IF THE MIL LIGHT CAME ON A CODE WOULD BE STORED. MY CONCERN IS MY CAR LOST POWER WHEN I REALLY NEEDED IT TO PASS SAFELY. THE DEALER SAID THE MANUFACTURER IS AWARE OF THE SAME PROBLEM BUT I WANT IT ON RECORD. I CHECKED THE ACURA FORUM AND FOUND OTHER OWNERS HAVE HAD THE SAME PROBLEM OF THE CAR GOING INTO LIMP MODE, THE MIL LIGHT COMING ON AND NO CODE STORED.

I DRIVE A 2020 ACURA RDX HAVING 1,840 MILES. WHILE DRIVING ON THE HIGHWAY ON TWO SEPARATE OCCASIONS (APPROXIMATELY SEVERAL MONTHS APART), MY CAR HAD SUDDENLY DECELERATED. MY FOOT WAS NOT ON THE BREAK AT ALL. THE CAR WOULD NOT ACCELERATE WHEN APPLYING MY FOOT ON THE ACCELERATOR. FORTUNATELY THERE WAS STILL ENOUGH FORWARD MOTION IN THE CAR FOR ME TO BE ABLE TO PULL OVER TO THE SIDE WITHOUT INCIDENT. AFTER A FEW SECONDS, I STEPPED ON THE ACCELERATOR AGAIN AND THE CAR HAD RETURNED TO NORMAL OPERATION. I BROUGHT THE CAR IN TO THE DEALERSHIP FOR SERVICE. THEY COULD NOT FIND OR DUPLICATE THE PROBLEM RELATED TO MY EXPERIENCES. I GAVE THEM COPIES OF MY INTERNET SEARCHES SHOWING OTHER DRIVERS' COMPLAINTS HAVING SIMILAR "LIMP MODE" EXPERIENCES. THE DEALERSHIP CLAIMED THEY ARE NOT AWARE OF THIS PROBLEM AND OF ANY COMPLAINTS. I FIND THIS RESPONSE ABSOLUTELY FRUSTRATING BECAUSE THE SAFETY OF MY FAMILY AND FRIENDS ARE AT STAKE. FOR NOW, I AM LIMITING MY DRIVING TO WHAT IS ONLY NECESSARY UNTIL THIS DEFECT IS RESOLVED. I AM ALSO CONSIDERING OTHER OPTIONS.
