ZF9 TRANSMISSION WENT OUT AT ABOUT 10,000 MILES WITH METAL PARTICLES FOUND IN ATF FLUID. REPLACED BY ACURA WITH A NEW TRANSMISSION APPARATUS. APPARENTLY THIS IS A RAMPANT AND DANGEROUS PROBLEM WITH THIS MODEL YEAR TRANSMISSION. NOW AT 38,000 MILES (28,000 MILES ON THE NEW TRANSMISSION) THIS ONE IS FAILING, SLIPPING ON SHIFTS AND MAKING A SQUEAKING/CHIRPING NOISE BETWEEN GEARS. CAN RESULT IN FAILURE TO ENGAGE/ACCELERATE IN AN EMERGENCY SITUATION. ACURA PEOPLE WON'T TAKE IT SERIOUSLY SO NHTSA SHOULD GET INVOLVED. A QUICK SURVEY WILL DEMONSTRATE THIS IS A COMMON PROBLEM IN THIS CAR. ACURA HAS A TSB BUT THIS SHOULD BE A RECALL ITEM. THEY'RE TRYING TO GET BEYOND EVERYONE'S 6 YEAR POWERTRAIN WARRANTY WITHOUT HAVING TO TAKE ACTION.

MY 2016 MDX HAS HAD ITS TRANSMISSION REPLACED TWICE. THE SYMPTOMS ARE USUALLY "CHIRPING" NOISES AND/OR ROUGH/VIOLENT SHIFTING BEHAVIOR. ON THE VERY DAY THAT I PICKED THE VEHICLE UP FROM THE ACURA SERVICE SHOP AFTER ITS 2ND TRANSMISSION REPLACEMENT, THE VEHICLE STILL WILDLY EXHIBITED "CHIRPING" NOISES, ALL OF WHICH ARE DOCUMENTED IN A YOUTUBE VIDEO THAT WE TOOK WHILE DRIVING THE VEHICLE HOME THAT DAY. EVEN AFTER 2 TRANSMISSION REPLACEMENTS, THE TRANSMISSION IS BEGINNING TO EXHIBIT THE SAME SYMPTOMS YET AGAIN. THIS IS A LEMON TRANSMISSION. THIS WEEK, I HAD AN INDEPENDENT MECHANIC WHO SPECIALIZES ONLY IN ACURA/HONDA VEHICLES INSPECT THE TRANSMISSION. HE DOCUMENTED THE "CHIRP" NOISE AS WELL AS "HARSH" AND "ERRATIC" SHIFTING. THIS IS ALL DOCUMENTED IN WRITING ON HIS WORK ORDER RECEIPT, WHICH I CAN PROVIDE UPON REQUEST. THIS MECHANIC ALSO SUGGESTED THAT IF THE TRANSMISSION FAILS, IT COULD CAUSE A CATASTROPHIC CRASH AND POTENTIAL INJURY OR DEATH TO OCCUPANTS DEPENDING ON THE SITUATION. PRIOR TO THE INDEPENDENT MECHANIC EXAMINING THE VEHICLE, MY LOCAL ACURA SERVICE SHOP GAVE ME THE "RUN-AROUND" SONG-AND-DANCE BY SAYING THEY CAN'T FIX ANYTHING BECAUSE THEY WERE "UNABLE TO RECREATE THE SYMPTOMS". THEY STATED THIS DESPITE THE FACT THAT I HAVE EXTENSIVE VIDEO/AUDIO EVIDENCE OF THE SYMPTOMS ON YOUTUBE OF MY SPECIFIC VEHICLE.

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.

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.

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.

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.
