AFTER COMING TO A STOP OR SLOWING DOWN TO A VERY LOW SPEED, WHEN I REACCELERATE TO BUILD SPEED, THE TRANSMISSION STALLS AND THEN JERKS INTO GEAR WHILE IN ECO-MODE. AT TIMES THIS IS ALMOST CAUSING A COLLISION. I REPORTED THIS TO THE DEALERSHIP ALMOST A MONTH AFTER MY PURCHASE AND 4 MORE TIMES AFTER THE FIRST REPORT AND EACH TIME THEY HAD NO RESOLUTION EXCEPT THE LAST TIME TO DO A TRANSMISSION FLUSH WHICH I HAD TO PAY FOR. IN SOME OF SUGGESTIONS AND QUESTIONS, IT APPEARS THAT THE DEALERSHIP KNOWS THAT THERE'S AN ISSUE.

MY WIFE HAS REPORTED ON SEVERAL OCCASIONS THAT WHEN THE IDLE-STOP FEATURE IS TURNED ON AND THE VEHICLE HAS COME TO A STOP, THE ENGINE CUTS AS INTENDED BUT WILL NOT RESTART WHEN PRESSURE IS RELEASED FROM THE BRAKE. NUMEROUS LIGHTS WITHIN THE INSTRUMENT PANEL, WITH THE EXCEPTION OF THE CHECK ENGINE LIGHT, ILLUMINATE, THE TRANSMISSION SHIFTS ITSELF INTO NEUTRAL. THE VEHICLE SAYS TO SHIFT INTO "PARK", PRESS AND HOLD THE BRAKE AND RESTART THE VEHICLE USING THE START/STOP BUTTON. I HAVE TRIED TO DUPLICATE THIS WHILE DRIVING THE VEHICLE. YESTERDAY, THIS SAME OCCURRENCE HAPPENED TO ME ONLY I WAS NOT ABLE TO READILY RESTART THE VEHICLE. THIS LATEST OCCURRENCE HAPPENED IN HEAVY TRAFFIC AT A BUSY INTERSECTION. MY WIFE REPORTS HAVING HAD THIS OCCUR AT LEAST SIX TO SEVEN TIMES, ONCE WHILE IN TRAFFIC ON THE FREEWAY. I HAVE BROUGHT THE VEHICLE TO HONDA IN THE PAST BECAUSE OF THE VEHICLE JJUTTERING AT LOW SPEEDS AND BECAUSE OF THIS ISSUE. EACH TIME I WAS TOLD THAT BECAUSE NO ERROR CODE WAS FOUND AND THE ISSUE COULD NOT BE DUPLICATED, THERE WAS NOTHING THEY COULD DO. THIS ISSUE IS A POTENTIAL DISASTER WAITING TO HAPPEN.

FOR ROUGHLY THE LAST 4 MONTHS, MY CAR STALLS AT A STOP (STOP SIGN, TRAFFIC LIGHT, ETC) BY SHIFTING ITSELF INTO NEUTRAL. THE CAR HAS A PUSH BUTTON GEAR SHIFT AND THE WARNING LIGHT SAYS TO SHIFT THE CAR INTO PARK. SOMETIMES, I CAN SHIFT THE CAR INTO PARK AND SOMETIMES I CAN'T SHIFT THE BUTTONS AT ALL. IF I AM ABLE TO SHIFT INTO PARK, A MESSAGE ON MY DASHBOARD LIGHTS UP AND STAYS 'TO SHIFT FROM P, ENGINE MUST BE RUNNING'. EITHER WAY, I HAVE TO TURN MY CAR OFF AND BACK ON AGAIN IN ORDER TO BE ABLE TO DRIVE. THE FIRST TIME THIS PROBLEM HAPPENED, I CALLED THE DEALER AND THEY THOUGHT THAT POSSIBLY SOMETHING GOT LODGED IN THE GEAR SHIFT. HOWEVER, AS TIME GOES ON, THESE EVENTS BECOME MORE AND MORE COMMON. OUR LOCAL HONDA DEALER HAD MY CAR FOR ROUGHLY A WEEK IN JUNE AND TRIED TO RECREATE THE PROBLEM. THEY WERE UNABLE TO DUPLICATE IT AND DID A FACTORY RESET. THAT WORKED FOR ABOUT A MONTH. NOW, THE STALLING HAPPENS AT LEAST ONCE A WEEK AND YESTERDAY IT HAPPENED THREE TIMES IN THE MATTER OF AN HOUR. WHEN I TOOK THE CAR TO THE DEALER IN JUNE, IT HAD ALSO STALLED THREE TIMES IN AN HOUR. I FEEL AT HIGH RISK DRIVING THE VEHICLE BECAUSE CARS GET IMPATIENT BEHIND ME AND START MOVING WHEN THE LIGHT TURNS GREEN EVEN THOUGH I CAN'T MOVE. OR, IF CARS ARE APPROACHING A GREEN LIGHT, THEY PROBABLY WON'T REALIZE THAT I AM UNABLE TO MOVE MAKING THIS A HUGE SAFETY CONCERN. THIS PROBLEM HAPPENS EVERYWHERE BUT ON THE HIGHWAY.

HONDA KNOWS THAT THERE IS A PROBLEM WITH THE TRANSMISSION THAT CAUSES THE FLUID TO OVERHEAT. THE OVERHEATING ISSUE LEADS TO A 'JUDDER' IN THE TRANSMISSION. THE CAR ACCELERATES IN A VERY JERKY WAY ESPECIALLY BETWEEN 30 AND 50. THIS IS A BIG SAFETY ISSUE IF YOU ARE TRYING TO PASS SOMEONE. AS SOON AS THE VEHICLE REACHES 80,000 MILES HONDA WILL NO LONGER COVER THE SO-CALLED 'REPAIR' WHICH IS TO FLUSH THE BURNT TRANSMISSION OIL MULTIPLE TIMES. THIS COSTS ALMOST $400. HONDA KNOWS THEY HAVE A DEFECTIVE TRANSMISSION AND, INSTEAD OF FIXING IT, THEY ARE PASSING THE TRANSMISSION FLUSH COST ON TO THE BUYERS. A RECALL SHOULD BE ISSUED BEFORE SOMEONE GETS KILLED TRYING TO PASS IN A VEHICLE WITH A FAULTY TRANSMISSION. ALREADY HAPPENED TWICE ON MY PILOT. FIRST TIME WAS REPAIRED FOR FREE, SECOND TIME I HAD TO PAY SINCE MY CAR HAS 86000 MILES AND THEY ONLY COVER UNDER 80000.

THE AUTO ENGINE IDLE (AEI) FEATURE HAS A FLAW IN IT THAT HONDA HAS APPARENTLY NOT IDENTIFIED OR EXPLAINED AND IT IS A SERIOUS SAFETY CONCERN. AEI SHUTS THE ENGINE OFF WHEN THE CAR IS IN DRIVE BUT FULLY STOPPED AND, IN THEORY, INCREASES FUEL EFFICIENCY BY REDUCING ENGINE IDLING WHEN THE CAR IS STOPPED, E.G. AT A STOPLIGHT OR IN STOP-AND-GO TRAFFIC. WHILE THERE IS A BUTTON TO DISABLE IT, THIS BUTTON HAS TO BE PRESSED EACH TIME YOU TURN THE CAR ON AND CANNOT BE PERMANENTLY DISABLED. WE TRY TO REMEMBER TO ALWAYS PRESS THE BUTTON AND DISABLE THE FEATURE BUT OCCASIONALLY FORGET AND DON'T REALIZE WE HAVEN'T DISABLED IT UNTIL WE COME TO A STOP SOMEWHERE AND THE FEATURE ENGAGES AND THE ENGINE SHUTS OFF. AEI WOULD JUST BE A NUISANCE IF IT WORKED 100% OF THE TIME AS IT IS DESIGNED TO WORK BUT, UNFORTUNATELY, IT DOESN'T. WHEN IT WORKS AND THE BRAKE PEDAL IS FULLY DEPRESSED, THE ENGINE IS AUTOMATICALLY IDLED, AND THEN AS YOU BEGIN TO LIFT YOUR FOOT OFF THE BRAKE PEDAL, THE ENGINE QUICKLY TURNS BACK ON, YOU'RE ALREADY IN DRIVE, AND YOU GO. HOWEVER, ON WHAT SEEMS TO BE A COMPLETELY RANDOM AND UNPREDICTABLE BASIS, SOMETIMES WHEN YOU BEGIN TO LIFT YOUR FOOT OFF THE BRAKE PEDAL, RATHER THAN HAVING THE ENGINE RESTART AUTOMATICALLY, THE ENTIRE CAR JUST GOES DEAD. AT THIS POINT, YOU HAVE TO FRANTICALLY PUT THE CAR IN PARK AND COMPLETELY RESTART THE ENGINE. IF YOU'RE LUCKY, THIS HAPPENS QUICKLY AND YOU'RE NOT STUCK IN A COMPROMISED SPOT WITH NO ONE BEARING DOWN ON YOU FROM BEHIND BUT BY ITS DESIGN YOU ARE SOMEWHERE YOU NEED AND WANT TO BE MOVING FROM QUICKLY, AND IT HAS HAPPENED AT THE EXACT MOMENT WHEN YOU TRY TO ACCELERATE. THIS HAS HAPPENED TO BOTH MYSELF AND MY WIFE A HANDFUL OF TIMES IN SCARY SITUATIONS. READ ALL THE OTHER COMPLAINTS ON THE INTERNET - NO SERVICE REP ANYWHERE HAS AN EXPLANATION.

PE25008 · 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.

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.
