ISSUE: CAR IS UNABLE TO START WHEN ON A CITY STREET AND AUTO-START IS ENABLED (STALLING). THIS HAS HAPPENED ON SEVERAL OCCASIONS OVER THE LAST COUPLE YEARS. MY WIFE IS THE PRIMARY DRIVER SHE OFTEN HAS THE KIDS IN THE CAR WHICH CREATES A LARGE SAFETY ISSUE FOR MY FAMILY. WHEN THE PROBLEM FIRST PRESENTED ITSELF, THERE WAS ONE TIME WHERE THE CAR UNINTENTIONALLY ACCELERATED ON IT'S OWN WITH MY FAMILY IN THE CAR. UNFORTUNATELY THAT WAS NOT ABLE TO BE REPLICATED AS WELL NOR HAVE WE EXPERIENCED IT AGAIN. POTENTIAL SOLUTION 1: BATTERY HAS BEEN REPLACED WHICH TEMPORARILY STOPPED THE ISSUE, HOWEVER WITHIN MONTHS THE ISSUE IS BACK. POTENTIAL SOLUTION 2: IT'S WORTH NOTING THAT THE TRANSMISSION WAS REPLACED RECENTLY, HOWEVER IT WAS NOT DUE TO THIS THE STALLING ISSUE, THERE WAS AN ACTUAL ISSUE WITH THE TRANSMISSION. THE STALLING STOPPED FOR A WHILE AS WELL, THEN CAME BACK AGAIN. CONCERNS: WE ARE CONCERNED WITH OUR SAFETY IN THIS VEHICLE WHICH DOESN'T GIVE OWNERSHIP OF THIS CAR A GOOD FEELING. WHILE WE CAN CHOSE TO SELL THIS CAR AND PASS THIS ISSUE TO SOMEONE ELSE WHO IN TURN COULD GET HURT OR KILLED IF THEY ARE IN THE WRONG PLACE AT THE WRONG TIME AND THAT SHOULD NOT BE THE CASE. WE SHOULDN'T WAIT FOR PEOPLE TO GET HURT/KILLED BY THIS TO DO SOMETHING ABOUT IT. WE'RE HOPING WITH THE CONTINUED REPORTS OF THIS ISSUE THERE WILL BE SOMETHING DONE BY HONDA TO RESOLVE THIS. WE'RE NO LONGER PROUD OF OUR OWNERSHIP OF THIS CAR DUE TO THE SAFETY HAZARD THIS HAS PRESENTED TO OUR FAMILY. TIME OF INCIDENT MILEAGE PROVIDED WAS FROM 7/2018 - IT OCCURRED PRIOR TO THAT AND AFTER.

THE IDLE START/STOP FEATURE CAUSES THE CAR TO STALL WHEN STOPPED. WHEN THE AT A FULL STOP AND THE IDLE/STOP KICKS IN THE CAR DOES NOT COME BACK ON AND SHUTS OFF WITH ALL OF THE LIGHTS IN THE CONSOLE LIGHTING UP AND MUST BE COMPLETELY SHUT-OFF AND RESTARTED, "STALL OUT" AT A STOP LIGHT OR STOP SIGN WHEN I WAS IN "AUTO IDLE-STOP" AND PRESSED ON THE GAS. I FIRST NOTICED THAT THE AUTO IDLE-STOP WAS HESITATING WHEN IT WOULD START UP. I ALSO NOTICED THAT THE RADIO WOULD "CUT OUT". AFTER THAT, THE VEHICLE WOULD JUST STALL OUT AND I WOULD HAVE TO PUSH PARK, PUT MY FOOT ON THE BRAKE AND THEN PUSH START. TOOK TO THE DEALER DURING MY LAST SERVICE ON JANUARY 20, 2020 AND THEY COULD NOT DUPLICATE. THE ISSUE HAS PROGRESSIVELY GOTTEN WORSE AND IS HAPPENING MORE FREQUENTLY. THE CAR HAS STALLED AT LIGHTS AND POSES A DANGER TO MY WIFE AND 3 YOUNG CHILDREN. THE DEALERSHIP WILL NOT LOOK INTO IT ANY FURTHER BECAUSE THEY CANNOT DUPLICATE THE PROBLEM. I'VE RESEARCHED FORUMS ONLINE AND OTHER HONDA PILOT OWNERS HAVE EXPRESSED THEY ARE EXPERIENCING THE SAME ISSUE.

WE OWN A 2016 HONDA PILOT ELITE WITH AUTO START/STOP FEATURE. THE VEHICLE HAS APPROXIMATELY 78,000 MILES AND BEGAN EXHIBITING ISSUES WITH THE AUTO START/STOP FEATURE. WHEN STOPPED AT ANY LOCATION, THE AUTO STOP ENGAGES AND TURNS OFF THE ENGINE AND SHOULD RESTART WHEN YOU LIFT YOUR FOOT OF THE BRAKE; BUT IT IS NOW TURNING ALL THE POWER TO THE VEHICLE OFF (RADIO OFF, A/C OFF, DASH LIGHTS OFF). IN SOME CASES THE DASH WILL FLICKER WITH AND DASH LIGHTS WILL ELIMINATE FOR A SECOND. AS A RESULT YOU CANNOT MOVE THE VEHICLE AND ARE STUCK IN A DANGEROUS PLACE (CAN'T PUT THE VEHICLE IN NEUTRAL, NO POWER). THIS HAS HAPPENED TO US ON NUMEROUS OCCASIONS; AT STOP LIGHTS WHERE CARS BEHIND YOU GET FRUSTRATED AND HONK THEIR HORNS (TAKES SEVERAL MINUTES TO START BACK UP IF YOU ARE LUCKY) AND MOST CONCERNING IS IF YOU ARE IN THE MIDDLE OF THE INTERSECTION AND ABOUT TO MAKE A RIGHT TURN, WHILE WAITING TO MAKE THE TURN, THE VEHICLE SHUTS OFF ' NOW WE ARE STUCK IN THE INTERSECTION WITH TWO KIDS IN THE VEHICLE. NOW ONCOMING TRAFFIC IS EITHER FAST APPROACHING OR HONKING BECAUSE WE ARE BLOCKING THE LANE. WE HAVE BEEN ALMOST STRUCK ON SEVERAL OCCASIONS. THE ONLY WORK AROUND IS TO TURN THE AUTO START/STOP FEATURE OFF (PUSHING THE BUTTON) WHEN YOU FIRST GET IN THE VEHICLE, BUT IF YOU FORGET ' WE MIGHT GET KILLED. I TOOK IT TO THE HONDA DEALER AND THEY CLAIM THEY HAVE NEVER HEARD OF THIS ISSUE. MY BATTERY TESTED FINE. I LOCATED NUMEROUS HONDA PILOT POSTS ONLINE THAT INDICATE THIS IS A COMMON PROBLEM, DATING BACK TO THE 2016, BUT NO ONE IS HELPING THE CONSUMER. I DON'T UNDERSTAND WHY THERE IS A DELAY IN REPAIRING THIS ISSUE; IT IS NOT JUST A GENERAL INCONVENIENCE, IT IS A SAFETY RISK. WE ARE FRUSTRATED AND SCARED. IF WE TRADE THE VEHICLE FOR ANOTHER CAR, WHAT HAPPENS TO THE NEXT FAMILY THAT PURCHASES THIS VEHICLE ' DO THEY SUFFER THE FATAL OUTCOME.

NO EMERGENCY LIGHT, NO LIGHTS ON DASHBOARD, CANNOT LOCK CAR, CANNOT PUT INTO NEUTRAL, MUST BE TOWED. CAR FIRST STARTED STOPPING AT STOP LIGHTS IN CITY STREETS IN 2017. WOULD TAKE A FEW ATTEMPTS TO RESTART. BROUGHT TO DEALER TO STATE MY CONCERN THAT IT WOULD HAPPEN IN THE FREEWAY AND THEY CHECKED AND SAID EVERYTHING WAS FINE. ON 3/19/20, DRIVING IN THE FREEWAY, I HAD TO STOP FOR TRAFFIC. CAR DIED COMPLETELY. I COULDN'T EVEN TURN ON THE EMERGENCY LIGHT. I HAD TO OPEN MY DOOR A LITTLE BIT, STICK MY ARM OUT AND WAVE FOR ONCOMING TRAFFIC BEHIND ME. SEMI TRUCKS WERE QUICKLY CHANGING LANES TO AVOID REAR-ENDING ME. IT WAS THE MOST FRIGHTENING INCIDENT THAT HAS EVER HAPPENED TO ME. CAR WAS TOWED TO DEALER AND THEY SAID IT WAS A TRANSMISSION SENSOR ERROR AND CLAIMED TO HAVE FIXED IT. 4/2/20 AS MY DAUGHTER AND I WERE EXITING THE FREEWAY, THE PROBLEM OCCURRED AGAIN. WE STOPPED AT THE LIGHT AT THE END OF THE EXIT WHEN THE CAR JUST STALLED. AGAIN TOTALLY DEAD. IT'S JUST A PARKED CAR THAT CANNOT BE RESTARTED. CAR WAS TOWED TO DEALER. I DON'T KNOW WHAT'S WRONG WITH IT. THE DEALER'S ATTEMPTS TO FIX IT DID NOT WORK. THE DEALER WAS CLOSED WHEN WE DROPPED IT OFF TONIGHT. THIS IS A VERY DANGEROUS SITUATION. THE CAR JUST DIES AND WILL NOT RESTART. THERE IS NOT EVEN A WAY TO TURN ON THE EMERGENCY BLINKING LIGHTS TO ALERT OTHER MOTORISTS OF A STALLED CAR.

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.
