WHEN DRIVING AT HIGHWAY SPEEDS FOR AT LEAST A HALF HOUR AND ATTEMPTING TO ACCELERATE, THE ENGINE SPEED WILL DROP TO IDLE AND WILL NOT RESPOND TO ACCELERATOR PEDAL MOVEMENT FOR SEVERAL SECONDS. WHEN THIS HAPPENS, THERE ARE NO: WARNINGS, LIGHTS, OR MESSAGES AND NO FAULT CODES ARE STORED IN ANY OF THE CONTROL MODULES. THIS HAS NEVER HAPPENED WHEN USING CRUISE CONTROL. THIS HAS HAPPENED ON AT LEAST 9 DIFFERENT TRIPS. THIS IS AN EXTREMELY DANGEROUS CONDITION THAT HAS NEARLY RESULTED IN ANOTHER VEHICLE IMPACTING OURS FROM BEHIND, DUE TO THE RAPID DECELERATION.

SINCE WE PURCHASED THIS CAR WE HAVE ISSUES WITH THE VEHICLE WHERE IT IS HESITATING TO ACCELERATE WHEN GOING FROM 0 MPH TO 30 MPH. WE TOOK IT TO THE DEALERSHIP AND THEY UPDATED THE SOFTWARE FOR THE POWERTRAIN BUT STILL THE VEHICLE HAS ACCELERATION ISSUES WHEN GOING FROM 0 TO 40 MILES PER HOUR. WE HAVE RESEARCHED THIS ISSUE ON INTERNET AND IT SEEMS LIKE LOTS OF PEOPLE OWNING ACURA ARE HAVING THIS ISSUE. THIS ISSUE IS ATTRIBUTED TO NEW 7 SPEED TRANSMISSION THAT ACURA BUILT. IT LOOKS LIKE A SAFTEY ISSUE SINCE THE VEHICLE WOULD NOT ACCELERATE AFTER STOPPING AT TRAFFIC LIGHT OR STOPPING TO TAKE RIGHT AND RE ACCELERATING.

NOVEMBER 10, 2019 TRAVELING ON HIGHWAY AT ~65 MPH, PRESSED ACCELERATOR TO PASS CAR AND VEHICLE WOULD NOT SPEED UP...FELT LIKE THE CAR WAS IN NEUTRAL. AFTER ABOUT 7 TO 10 SECONDS THE TRANSMISSION FINALLY KICKED IN AND THE CAR ACCELERATED. IF THIS HAPPENED ON A 2 LANE ROAD THE LACK OF TRANSMISSION DELIVERING POWER TO WHEELS COULD HAVE RESULTED IN A HEAD ON COLLISION. SERVICE APT SCHEDULED WITH ACURA DEALERSHIP WHERE PURCHASED AND WAS TOLD THEY COULD FIND NO 'CODES' OR ALERTS IN CARS COMPUTER AND THAT THEY FOUND NOTHING WRONG. THE DID SAY THEY REPROGRAMMED THE TRANSMISSION SOFTWARE...BUT THEY HAVE DONE THAT 2 OTHER TIMES. CAR HAS ONLY 35K MILES ON IT AND WE HAVE BROUGHT CAR INTO ACURA DEALERSHIP 4 TIMES TO ADDRESS THE HARSH SHIFTING OF TRANSMISSION AND TOLD THEM EACH TIME WE FELT IT WAS A SERIOUS SAFETY CONCERN. THE ABOVE INCIDENT OF NO POWER WHEN ATTEMPTING TO PASS ON HIGHWAY IS THE FIRST TIME THAT HAS HAPPENED..BUT IS A VERY SERIOUS CONCERN. WE WERE TOLD FOR THE 3RD TIME THAT THE HARSH SHIFTING AND GEAR-WANDERING WAS A 'CHARACTERISTIC' OF THIS MAKE / MODEL CAR AND THAT ACURA HAS BEEN TRYING TO ADDRESS THE ISSUE WITH TRANSMISSION SOFTWARE UPDATES. I HAVE SEEN MANY ONLINE COMPLAINTS OF THE "GEAR-WANDERING' TRANSMISSION ISSUE ONLINE AND HAVE ALSO READ SIMILAR SAFETY COMPLAINTS OF CAR LOSING TRANSMISSION POWER AT HIGHWAY SPEEDS. PLEASE THOUGHTFULLY REVIEW THIS COMPLAINT AND CONTACT ME IF YOU NEED ADDITIONAL INFORMATION. WE FIRMLY BELIEVE THAT THE KNOWN REPORTED ISSUES OF THE 2016 ACURA MDX SHAWD TRANSMISSION PROBLEMS ARE A HUGE SAFETY ISSUE. THIS 7 SEATER SUV IS DRIVEN BY MANY FAMILIES!

EXPERIENCE THREE DIFFERENT SCENARIOS WHERE THE TRANSMISSION EITHER APPEARS TO SHIFT INTO NEUTRAL OR GEARS GRINDING. 1) SHIFTING FROM PARK TO DRIVE, THE VEHICLE ALL OF A SUDDEN STALLS AND ENGINE REVS UP WITHOUT ANY MOTION. RESOLVED BY SHIFTING VEHICLE BACK TO PARK, AND THEN TO DRIVE. 2) WHEN VEHICLE IS IN-MOTION AT HIGHWAY SPEEDS BETWEEN 40-70 MPH, ALL OF A SUDDEN VEHICLE LOSES ACCELERATION POWER AND SPEED DECREASES FOR 3-4 SECONDS FORCING OTHER VEHICLES FROM BEHIND TO EITHER BRAKE OR SLOW DOWN. OFTEN OCCURS WHILE MERGING ONTO THE HIGHWAY OR LANE CHANGES WHERE ACCELERATION IS REQUIRED. 3) WHILE DRIVING ON NORMAL STREETS AT 30-40 MPH, GEARS GRIND FOR APPROXIMATELY 1-2 SECONDS WITHOUT LOSING ACCELERATION.

BEFORE SHARING THE DETAILS, YOU SHOULD KNOW THAT THIS COULD BE A DEADLY SAFETY MATTER. IF A TRANSMISSION FAILS AT HIGHWAY SPEEDS (OR ANY SPEED), THE VEHICLE LOSES POWER AND COULD VERY EASILY GET CRUSHED BY AN 18-WHEELER. A DRIVER AND/OR A WHOLE FAMILY COULD DIE. YOU SHOULD GO AFTER ACURA BEFORE SOMEONE HAS TO DIE AS A RESULT OF ACURA'S NEGLIGENCE. MY 2016 ACURA MDX HAD ITS FIRST TRANSMISSION REPLACEMENT IN OCTOBER 2016 AT AROUND 14,000 MILES AND ABOUT 18 MONTHS INTO OWNERSHIP. I HAD PURCHASED THE VEHICLE AS A BRAND NEW CAR FROM AN ACURA DEALER. I AM THE ONLY OWNER, AND IT HAS BEEN "BABIED" AND RECEIVED PROPER MAINTENANCE FROM ACURA DEALER SERVICE SHOPS ONLY. LEADING UP TO THE 1ST TRANSMISSION REPLACEMENT, THE VEHICLE WAS MAKING AWFUL "CHIRPING" NOISES UPON SLIGHT ACCELERATION AT SLOW SPEEDS. AFTER THE 1ST TRANSMISSION REPLACEMENT, ALL SEEMED FINE UNTIL RECENTLY. AT AROUND 38,000 MILES (SPRING 2019, STILL BARELY WITHIN THE 4 YEAR WARRANTY), THE VEHICLE BEGAN TO EXHIBIT IDENTICAL SYMPTOMS. AT 39,000 MILES, THE MDX RECEIVED ITS 2ND TRANSMISSION REPLACEMENT. ON THE VERY DAY THAT I PICKED IT UP FROM THE 2ND TRANSMISSION REPLACEMENT REPAIR WORK, THE MDX STARTED MAKING FAR WORSE NOISES THAN BEFORE THE REPAIR WORK. IT IS BACK IN THE SHOP AGAIN AND ACURA SEEMS TO BE AT A COMPLETE LOSS FOR HOW TO FIX IT PROPERLY FOR A 3RD TIME! THERE ARE MANY ACURA/HONDA TECHNICAL SERVICE BULLETINS ABOUT TRANSMISSION ISSUES ON THESE AND ACURA/HONDA-RELATED VEHICLES WHICH USE THE SAME TRANSMISSION. IT IS CLEARLY A WELL-KNOWN PROBLEM PUTTING COUNTLESS DRIVERS/PASSENGERS AT PHYSICAL RISK OR FINANCIAL RISK.

AT 80,000 MILES CAR STARTED MAKING A NOISE SOUNDING LIKE METAL SPINNING ON METAL. TRANSMISSION SYSTEM PROBLEM LIGHT CAME ON. RPMS WENT REALLY HIGH WHEN I TOOK MY FOOT OFF THE GAS THE RPMS WENT REALLY LOW. THIS ALL HAPPENED WHILE I WAS ON THE HIGHWAY. PULLED OVER, SHUT CAR OFF, RESTARTED CAR, WARNING LIGHT WENT AWAY RPMS WERE FINE BUT THE NOISE WAS STILL THERE. TOOK CAR IN FOR SERVICE THEY COULDN'T FIND ANY PROBLEM HAD TRANSMISSION FLUID REPLACED AND THE NOISE WENT AWAY HOWEVER OCCASIONALLY THE TRANSMISSION SYSTEM PROBLEM WOULD OCCUR. SO I SHUT OFF THE CAR RESTART AND THE PROBLEM GOES AWAY. SEEMS THE TRANSMISSION PROBLEM HAPPENS WHEN I'M ON THE HIGHWAY AND GOING UP HILL BETWEEN 60 AND 70 MILES AN HOUR WHEN THE RPMS GO SLIGHTLY ABOVE TWO. IT DOES NOT SEEM TO HAPPEN ON LEVEL GROUND. I DO MOSTLY CITY DRIVING AND PUT ANOTHER 50,000 MILES ON SINCE THE FIRST TIME THE PROBLEM HAPPENED. TOOK CAR IN FOR SERVICE WHILE THE LIGHT WAS ON, DIAGNOSTIC SHOWS TORQUE CONVERTER PROBLEM. THEY TELL ME I NEED A NEW TRANSMISSION. APPARENTLY 2016 MODELS YOU CANNOT REBUILD BECAUSE THERE ARE NO PARTS AVAILABLE. STILL DRIVING CAR TODAY WITH NO PROBLEM DOING CITY DRIVING BUT I ALWAYS PANIC WHEN I HAVE TO GET ON THE HIGHWAY. APPARENTLY I'VE GONE 60,000 MILES MORE WITH A TRANSMISSION THAT CANNOT GO ON A HIGHWAY UPHILL. JUST RECENTLY MY CAR IS BEEN GOING INTO NEUTRAL BY ITSELF AND IT STALLS OCCASIONALLY. THIS HAPPENS WHILE I'M DRIVING. I FEEL VERY UNSAFE BUT I DON'T HAVE THE MONEY TO REPLACE MY TRANSMISSION. I WISH THE TORQUE CONVERTER COULD BE REPLACED BUT THERE ARE NO PARTS AVAILABLE. I BELIEVE ACURA IS NOT ADMITTING TO A PROBLEM

3PE25008 · Engine Failure
Opened Aug 20, 2025 · No close date supplied
Status: open (inferred from source dates) · Engine
The Office of Defects Investigation (ODI) has received 414 reports of connecting rod bearing failures in the 3.5L V6 engine used in the following vehicles: Model Years (MY) 2018-2020 Acura TLX, MY2016-2020 Acura MDX, MY2016-2020 Honda Pilot, MY2018-2020 Honda Odyssey, and MY2017-2019 Honda Ridgeline. The subject engine failures were analyzed as part of a Recall Query (RQ24013). It was determined that these engine failures are outside the scope of Honda Recall 23V-751. Further, evidence gathered in conjunction with RQ24013 does not suggest this failure is caused by the same crankshaft manufacturing defect that is addressed by Honda in Recall 23V-751. Based on analysis of data from RQ24013, NHTSA has closed that investigation. The significant number of reports of engine failure in vehicles outside the scope of RQ24013 presents a potential safety risk that warrants further investigation. ODI is opening this Preliminary Evaluation (PE) to further evaluate the scope and severity of the potential problem and to fully assess the potential safety-related issues. To review the ODI reports cited in the Opening Resume ODI Report Identification Number document, go to NHTSA.gov.

On June 3, 2022, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE22005 after the agency received VOQs and several field reports concerning the Auto Idle Stop (AIS) feature on 2016-2019MY Honda Pilot vehicles. The complaints allege that the engine fails to restart on its own from a complete stop at a traffic light or road intersection with the AIS function engaged. The subject vehicles are equipped with a 3.5L engine with a 9-speed automatic transmission. On January 6, 2023, Honda released service bulletins 23-008 and 23-009. These service bulletins address the failure to restart issue in the 2016-2019MY Honda Pilot vehicles, as well as the 2015-2020 Acura TLX, 2016-2020 Acura MDX, 2019-2022 Honda Passport, and 2020-2023 Honda Ridgeline vehicles. The repair outlined in the service bulletins is a two-stage countermeasure to remedy the issue. The first stage is a Programmed Fuel Injection (“PGM-FI”) software update. The second stage is only deployed if the software update fails to remedy the issue. The second stage, depending on the model and model year, consists of replacement of the starter assembly, starter relays, and a valve adjustment. Additionally, Honda extended the warranty coverage to 10 years with unlimited mileage for vehicles requiring the second stage component replacement. ODI continues to receive complaints of the AIS failure to restart, with many complainants alleging the campaign countermeasures had been completed.NHTSA has reviewed Honda's Information Request Letter responses involving warranty claims, lawsuits, and consumer complaints in addition to ODI's own data. This Engineering Analysis is being opened to further consider the potential safety defect, including gathering additional data regarding Honda’s service campaign efficacy. ODI is additionally expanding the scope to encompass all vehicles addressed in Honda’s service bulletins 23-008 and 23-009 as well as newer model year vehicles, which are substantially similar to the vehicles covered by the service campaign. To review the ODI reports cited in the Opening Resume ODI Report Identification Number document, go to NHTSA.gov.

On June 3, 2022, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE22005 after the agency received VOQs and several field reports concerning the Auto Idle Stop (AIS) feature on 2016-2019MY Honda Pilot vehicles. The complaints allege that the engine fails to restart on its own from a complete stop at a traffic light or road intersection with the AIS function engaged. The subject vehicles are equipped with a 3.5L engine with a 9-speed automatic transmission. On January 6, 2023, Honda released service bulletins 23-008 and 23-009. These service bulletins address the failure to restart issue in the 2016-2019MY Honda Pilot vehicles, as well as the 2015-2020 Acura TLX, 2016-2020 Acura MDX, 2019-2022 Honda Passport, and 2020-2023 Honda Ridgeline vehicles. The repair outlined in the service bulletins is a two-stage countermeasure to remedy the issue. The first stage is a Programmed Fuel Injection (“PGM-FI”) software update. The second stage is only deployed if the software update fails to remedy the issue. The second stage, depending on the model and model year, consists of replacement of the starter assembly, starter relays, and a valve adjustment. Additionally, Honda extended the warranty coverage to 10 years with unlimited mileage for vehicles requiring the second stage component replacement. ODI continues to receive complaints of the AIS failure to restart, with many complainants alleging the campaign countermeasures had been completed.NHTSA has reviewed Honda's Information Request Letter responses involving warranty claims, lawsuits, and consumer complaints in addition to ODI's own data. This Engineering Analysis is being opened to further consider the potential safety defect, including gathering additional data regarding Honda’s service campaign efficacy. ODI is additionally expanding the scope to encompass all vehicles addressed in Honda’s service bulletins 23-008 and 23-009 as well as newer model year vehicles, which are substantially similar to the vehicles covered by the service campaign.

RQ24013 · Engine Failure
Opened Nov 8, 2024 · Closed Aug 20, 2025
Status: closed (inferred from source dates) · Engine
On November 8, 2024, the Office of Defects Investigation (ODI) opened Recall Query RQ24013 to assess the scope of Honda recall 23V-751 after receiving complaints that alleged connecting rod bearing failures in vehicles that were not within the scope of recall 23V-751. In November 2023, Honda recalled 248,999 various Model Year (MY)2016–2020 Honda and Acura vehicles equipped with the 3.5L V6 engine. Honda recalled these vehicles due to a crankshaft manufacturing defect that caused premature connecting rod bearing wear and engine seizure. While the out-of-scope failures involved in these complaints appear to have a very similar failure mechanism as the recalled engines, a thorough analysis of all available data from Honda has not indicated that the same manufacturing defect exists in the out-of-scope engines as the engines recalled by 23V-751. Based on this analysis ODI has determined that Honda has properly defined the scope of recall 23V-751. Consequently, ODI will close this RQ investigation. NHTSA will continue to investigate these complaints of engine failure as part of a new Preliminary Evaluation Investigation (PE25008). The Agency reserves the right to take additional action if warranted by new circumstances.
