I believe my transmission or the electrical component(s) to my transmission failed. I was driving down the road and all of a sudden my car shifted into neutral and would not allow me to accelerate so we had make our way to the shoulder to put the car in park. Having my vehicle thrown into neutral while driving and not being able to accelerate put not only us, but other drivers at serious risk! There were several warning messages popping up on our screen (see attached photos). In researching this issue, I found that there had been several TSBs and a class action lawsuit claiming the same issue faced by many drivers. It is currently at the Acura dealership getting serviced and they will be replacing the entire transmission and TCM harness under the CPO warranty. I cannot believe there has not been a recall on this potentially life-threatening issue.

Every since I've owned my 2016 Acura MDX I've had infrequent, and intermittent transmission issues. Several have been safety concerns: - Transmission is slow to engage when first pushing accelerator, leading to unexpected lag pulling into traffic - Transmission did not shift into park as expected, causing car to keep moving as I was opening door and starting to step out - Transmission slips and does not respond when accelerating to merge into fast lane on highway to pass slower traffic. Car speed stalls and you have to let off the gas and wait for a few seconds before the transmission reengages. - Overall horrible/hard shifting all the time... to which we're told... the car learns your driving style. We've reset it multiple times to try to get it to start learning again. No luck. - After coasting on highway, very hard shift with loud noise when you go to hit the accelerator All of these situations have happened numerous times over the past 2 years of owning this car. All of them infrequent, but also unexpected... leaving you to really worry if this is the time the transmission is going to let you down and cause you to wreck. Dealer now says a new transmission is needed, but I waited until 78,000 miles to first report it, so it's out of warranty now. Hoping Acura will step up and address this serious safety issue with the 9 speed transmission.

WHILE DRIVING WITH ADAPTIVE CRUSE CONTROL ON, I WAS APPROACHING SLOWER VEHICLE. I WANTED TO GO AROUND IT WITHOUT BREAKING. WHILE DRIVING ALREADY ON HIGH SPEED (70M/H) I PRESS ACCELERATION PEDAL SO I CAN SAFELY GO AROUND SLOWER VEHICLE. I WAS HALF WAY INTO PASSING LINE (LAST LEFT LINE), THERE WAS A CAR ALREADY BEHIND ME APPROACHING WITH HIGHER SPEED, WHEN I SUDDENLY COMPLETELY LOST POWER AND LOTS OF LIGHTS ILLUMINATED ON THE DASH. CAR BEHIND ME NOTICE THAT I START LOOSING SPEED RAPIDLY SO HE START BRAKING THAT I COULD HEAR HIS TIRES. I DIDNT KNOW WHAT TO DO SO I JUST KEPT GOING TO EMERGENCY STOPPING LINE WHERE I ALMOST CRASH INTO THE CONCRETE DIVIDER. I MANAGE TO STOP VEHICLE SAFELY BY PURE LUCK. AFTER STOPPING I NOTICE THAT CAR IS NOT SHIFTING, AND SH-AWD SYSTEM, BLIND SPOT ASS, EMISSION SYSTEM AND TRANSMISSION SYSTEM FAULT LIGHTS CAME ON. I CALLED INSURANCE AGENT TO SEND ROAD SIDE ASSISTANCE, BUT WHILE WAITING ON THE CALL I START THE CAR AGAIN (LIKE 15MIN AFTER THIS INCIDENT) AND ALL LIGHTS WERE STILL ON EXCEPT TRANSMISSION. I TRIED CAR AND IT WAS SHIFTING NORMALLY NOW, EXCEPT SH-AWD WAS NOT WORKING (I DIDNT HAVE POWER TO THE REAR DIFFERENTIAL). THIS COULD BE VERY TRAGIC EVENT IF BOTH ME AND THE DRIVER BEHIND ME DIDNT REACT PROPERLY. I HAD TWO MORE PASSENGERS IN THE CAR, FROM WHICH ONE WAS 15 MONTHS OLD CHILD. I WAS READING THAT THIS COULD BE TRANSMISSION SYSTEM UPDATE ISSUE, BUT MY DEALER DID UPDATE TRANSMISSION ALREADY.

IT IS A HUGE SAFETY ISSUE WHEN OTHER TRAFFIC IS ONCOMING AS YOU ARE EXPECTING TO "GO" & NOTHING HAPPENS WHEN PRESSING THE GAS PEDAL. THE DEALERSHIP INSPECTED THE VEHICLE UPON PURCHASE AT OUR REQUEST ON TWO OCCASIONS BUT TOLD US IT IS NORMAL & WILL ADJUST TO MY DRIVING STYLE. THIS IS NOT NORMAL.THEY SAID THEY UPDATED THE SOFTWARE BUT FOUND NOTHING WRONG WITH THE 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.

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.

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.
