I WAS MAILED A LETTER ABOUT A WARRANTY EXTENSION FOR MY ASSOCIATED VIN. I DEFINITELY HAVE EXPERIENCED ASSOCIATED ISSUES WITH MY MDX. AFTER CALLING THE ACURA DEALERSHIP ON 11/24/17, I WAS GIVEN AN APPOINTMENT FOR 11/28/17 AND I WAS TOLD THEY WOULD INSPECT MY CAR OVER 2 DAYS AND PROVIDE A LOANER CAR. MY EXPERIENCE WAS "TO SAY THE LEAST" THE INVERSE; EXTREMELY DISAPPOINTING. THE SERVICE TECHNICIAN TOOK MY CAR FOR A TEST DRIVE AND TOLD ME NOTHING WAS WRONG. IN ADDITION, THE SERVICE TEAM WAS EXTREMELY UNPROFESSIONAL AS ONCE AGAIN, THE CUSTOMER WAS WRONG. PLEASE ADVISE ABOUT THE NEXT STEPS FOR SERVICE. I AM EXTREMELY DISAPPOINTED WITH ACURA UNWILLINGNESS TO LISTEN TO THE CUSTOMER. I DID TAKE THE CAR FOR SERVICE ASSOCIATED WITH THIS ISSUE ABOUT A MONTH PRIOR. OVERALL PROBLEM IS MANY TIMES I EXPERIENCE SHIFTING AND ACCELERATING HESITATION THAT IS JERKY. WHICH INDICATES A PROBLEM WITH THE TRANSMISSION: THIS IS WHAT THE WARRANTY EXTENSION STATES .... THE TRANSMISSION SHIFTS POORLY.

AS THE VEHICLE IS MOVING AT 60 -70 MPH AND YOU DECELERATE OR REDUCE ACCELERATION THE RPM GOES TO ZERO, CAR CANNOT ACCELERATE AND YOU DO NOT CONTROL OVER ACCELERATION IN MOVING TRAFFIC. IF THE CAR IIS COASTING AND NOT ABLE TO HAVE A STABLE SPEED WITH MOVING TRAFFIC THIS IS CAN BE DANGEROUS. SUDDENLY, THE TRANSMISSION WILL ENGAGE WITH A SHARP ENGAGEMENT (METAL SOUND) OF THE TRANSMISSION AFTER ABOUT 6-10 SECONDS. I COMPLAINED TO THE DEALER AS THIS HAS HAPPENED SEVERAL TIMES. THEY SAID THEY COULD NOT HELP ME SINCE THERE WAS NOTHING WRONG AT THE TIME OF INSPECTION AND THEY HAVE NOT HEARD ABOUT THIS PROBLEM. LAST WEEK SIMILAR SITUATION OCCURRED EXCEPT THE DASHBOARD ERROR LIGHTS SHOWED SH-AWD, EMISSIONS, TRANSMISSION PROBLEMS AND REAR SIDE WARNING INDICATOR FAULT. I HAD TO PULL OF ONTO THE SIDE OF ROAD. ONCE IN PARK THE CAR WOULD ONLY GO INTO SPORT MODE IN FIRST GEAR. CALLED ACURA ROADSIDE ASSISTANCE AND THEY TOWED TO A LOCAL DEALER. NEXT MORNING THEY SAID IT WAS OK. ONCE THEY TESTED VIA DIAGNOSTICS THEY SAID THERE WERE ERRORS IN THE TRANSMISSION MODULATOR. HOPE THIS FIXES THE PROBLEM. CAR HAS 36K MILES ON THE ODOMETER. THE DEALER WAS VERY HELPFUL AND HELPED ME GET TEMPORARY TRANSPORTATION TO MY HOME CITY 4 HOURS AWAY. OTHER PEOPLE ON THE INTERNET ARE HAVING SIMILAR PROBLEMS THAT HAVE OCCURED TO ME. MY BIGGEST CONCERN IS ONCE THE CAR IS OUT OF WARRANTEE THIS BECOMES MY PROBLEM NOT THE MANUFACTURER. WHAT RECOURSE DO I HAVE IF THIS A DESIGN OR QUALITY DEFECT FOR ME AND OTHER CONSUMERS. CURRENT REPAIRS HAVE BEING COMPLETED AND UNKNOWN IF THIS PROBLEM WILL OCCUR AT FUTURE DATE.

DEAR SIR/MADAM - I WAS HEADING TO MY OFFICE FROM HOME ON THE HIGHWAY CA-84. WHILE DRIVING TODAY ON THE HIGHWAY AT AROUND 50MPH I HEAR SUDDEN LOUD POP UP SOUND FROM THE ROOF, I FELT LIKE AN EARTHQUAKE AND VEHICLE STARTING TO SHAKE. AS I SLOWED DOWN I FELT SOMETHING WRONG WITH SUNROOF. SINCE HIGHWAY LEADS TO THE BRIDGE AND HAS NO EXIT I CONTINUED TO DRIVE. HIGHWAY BECOMES INTERNAL ROAD AFTER 5 MILES. AS I GOT AN OPPORTUNITY I PARKED THE VEHICLE AND GET ABOVE TO CHECK WHAT REALLY HAPPENED. I WAS AMAZED TO SEE SUNROOF GLASS IS BROKEN, BUT MOST IMPORTANTLY THE ENTIRE CASING IS CAVING IN. THIS IS VERY SERIOUS SAFETY ISSUE. SINCE THIS VEHICLE IS PRIME FOR MY KIDS COMMUTE I'M NOT SURE HOW SAFE THIS VEHICLE IS.

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.
