IT HAPPENED TO MYSELF W/ MY CHILD IN MY CAR & THEN MY SPOUSE DRIVING MY CAR ALONE. HOWEVER THE SAME PROBLEM IS KNOWN TO HONDA BUT UNTIL SOMEONE IS KILLED, THEY ARE REFUSING TO ACKNOWLEDGE, THE CAMSHAFT SHUTTING OFF ALL CONTROLS WHILE DRIVING ON A HIGHWAY IS COMPLETELY DANGEROUS. AS AN EXPERIENCED DRIVER, I WAS ABLE TO AVOID A COLLUSION ON A MAJOR HIGHWAY SURROUNDED BY TRACTOR TRAILERS GOING 65MPH. ALTHOUGH THE HONDA DEALER HAS REPLACED THE CAMSHAFT TWICE ON MY 2016 HONDA PILOT WITH LESS THAN 46,000, I AM FEARFUL THIS WILL HAPPEN AGAIN. WE ARE LEFT WITH A BALANCE TO PAY OFF, THE SAFETY OF OUR FAMILY WHILE DRIVING THIS UNSAFE VEHICLE AND JUST CUT OUT LOSSES. HOWEVER, THIS WILL NOT SOLVE THE PROBLEM FOR THOSE WHO CANNOT AFFORD TO PURCHASE ANOTHER VEHICLE. I HAD A 2006 HONDA PILOT WITH VERY LITTLE PROBLEMS FOR 10 YEARS, 95K MILES ON IT. IT WAS WHY I PURCHASED ANOTHER HONDA PILOT. HOWEVER, I SPENT A LOT MORE MONEY. THIS 2016 PILOT WAS $30K WITH THE $10K TRADE IN. WE MAINTAIN ALL OUR VEHICLES AS WELL AS GARAGE KEEP THEM TO PROTECT THEM FROM THE HARSH PA WINTER ELEMENTS. AS A DRIVER FOR OVER 32 YEARS AND ZERO ACCIDENTS, I DO NOT WANT TO BE THE CAUSE OF A SERIOUS ACCIDENT BECAUSE HONDA IS NEGLECTING TO ACKNOWLEDGE THIS NEW GERMAN MADE ENGINE AS WELL AS THE TRANSMISSION IS A SIGNIFICANT PROBLEM. THERE HAVE BEEN OTHER PROBLEMS LIKE THIS ONE THAT BEGAN ONE YR AFTER PURCHASE I BROUGHT TO IMMEDIATE ATTENTION OF THE DEALER. I AM SURE THEY REPORT THESE FINDINGS TO THE MANUFACTURE AS WELL. THE REMOTE KEY STOPPED WORKING, SEVERAL INTERIOR OUTLETS FOR CHARGING HAS STOPPED WORKING, A DOME LIGHT DOESN'T WORK, THE GARAGE DOOR OPENER CAN'T BE PROGRAMMED ANYMORE AND OTHER FEATURES ARE NO LONGER WORKING. IT IS A DANGEROUS CAR TO DRIVE WITH THE RISK OF STARTING ON FIRE AS WELL AS STOPPING ABRUPTLY LIKE IT DID FOR ME IN 2018 AND 2021 FOR MY HUSBAND. VINART LV HONDA EMMAUS, PA

TWO MAIN PROBLEMS: 1) VEHICLE WON'T START AND DISPLAYS "KEYLESS START SYSTEM ERROR". HONDA ISSUED A RECALL RELATED TO THIS ISSUE AND LOCAL DEALERSHIP REPLACED ENGINE START/STOP SWITCH ASSEMBLY. PROBLEM AND ERROR MESSAGE RETURNED AGAIN 3 DAYS LATER. ON RETURN TRIP TO THE DEALERSHIP, THEY TRIED TO BLAME IT ON A WEAK (5 MONTH OLD) BATTERY. (I TESTED BATTERY AT 3 DIFFERENT AUTO PARTS STORES AFTER TRIP TO DEALERSHIP; BATTERY TESTS AS GOOD AS NEW). COUNTLESS COMPLAINTS REGARDING THIS ISSUE ON INTERNET MESSAGE BOARDS, OWNERS' MESSAGE BOARDS AND HONDA SERVICE BULLETIN (20-117) HAS BEEN ISSUED. CHANGING THE START/STOP SWITCH DOESN'T APPEAR TO SOLVE THE PROBLEM IN ALL VEHICLES. 2) PROBLEM WITH ENGINE NOT AUTO RE-STARTING AFTER GOING INTO AN AUTO IDLE STOP. HAS HAPPENED MULTIPLE TIMES WITH MY VEHICLE, INCLUDING TWICE WHILE ATTEMPTING TO NAVIGATE THROUGH AN INTERSECTION DURING START AND STOP TRAFFIC. HIGHLY UNSAFE SITUATION. I'M NOT AWARE OF ANY RECALLS ON THIS ISSUE, BUT NUMEROUS HONDA TECHNICAL RESEARCH & SUPPORT GROUP 'DEALERSHIP ONLY' MESSAGES HAVE BEEN ISSUED REGARDING THIS PROBLEM. TESTING AT THE LOCAL DEALERSHIP COULDN'T LOCATE ANY PROBLEMS. I TURN OFF THE AUTO IDLE STOP FEATURE IMMEDIATELY WHEN USING THE VEHICLE TO KEEP FROM GETTING STUCK IN TRAFFIC AGAIN.

THE FIRST MESSAGE ON THE DASH BRIEFLY FLASHED 'CRASH MITIGATION PROBLEM' AND THEN INSTRUCTED ME TO PUT THE CAR IN PARK AND PUSH THE ENGINE START BUTTON. AFTER THIS INCIDENT, I TURNED OFF THE CRASH MITIGATION SYSTEM. A COUPLE DAYS LATER (TODAY), THE SAME THING HAPPENED. NO CRASH MITIGATION SYSTEM FLASH BUT INSTRUCTIONS TO PUT THE CAR IN PARK AND PRESS THEN ENGINE START BUTTON. BOTH TIMES THE ENGINE WAS ON AND IN DRIVE. AUTO IDLING WAS ENABLED. I HAVE ONLY OWNED THIS CAR FOR TWO MONTHS.

OVER THE PAST FEW YEARS, I HAVE HAD ISSUES WITH MY CAR SHUTTING OFF WHEN AT A STOP AFTER THE AUTO OFF FEATURE ENGAGES AND DOES NOT TURN BACK ON. I HAVE TO PUT THE CAR IN PARK AND MANUALLY RESTART THE ENGINE TO CONTINUE. THIS WAS HAPPENING AT LEAST A COUPLE TIMES A MONTH. I TOOK IT TO THE HONDA DEALER AND NO PROBLEM WAS FOUND ACCORDING TO THE DEALER. I BEGAN TO GET IN THE HABIT OF DISABLING THE AUTO OFF FEATURE EVERY TIME I STARTED THE CAR AND THIS SEEMED TO AVOID THIS PROBLEM I WAS HAVING. TWO DAYS AGO, HOWEVER, WHEN I WAS DRIVING, IT BEGAN TO SHUT OFF EVERY TIME I WAS IDLING AT A RED LIGHT (8 TIMES IN ONE DAY) EVEN WITH THE AUTO-OFF DISABLED. AND WHEN I GOT ON THE FREEWAY, DRIVING AT ABOUT 55MPH, THE ENGINE SHUT OFF AND I HAD TO EMERGENTLY COAST OVER PAST THE FAST LANE INTO A NARROW INSIDE SHOULDER. I HAD MY YOUNG CHILDREN AND ELDERLY PARENTS IN THE CAR AND IT WAS A VERY SCARY AND DANGEROUS EXPERIENCE FOR US. WE WERE THANKFUL ABLE TO RESTART THE CAR AND GET OFF THE FREEWAY WITH THE CAR SHUTTING OFF TWO MORE TIMES IN THE MIDDLE OF THE STREET WHILE DRIVING AT SLOW SPEEDS (10-20 MPH) BEFORE ARRIVING AT A GAS STATION PARKING LOT. THE DISPLAY CYCLED THROUGH MANY ERROR MESSAGES IE EMISSION SYSTEMS PROBLEM, POWER STEERING SYSTEM PROBLEM, TRANSMISSION SYSTEM PROBLEM, EMISSIONS SYSTEM PROBLEM, HILL START ASSIST PROBLEM, ETC. I AM VERY CONCERNED THAT WE HAVE GOT CONTINUED TO HAVE PROBLEMS WITH THIS VEHICLE SHUTTING OFF WHICH IS VERY DANGEROUS.

THE AUTO SHUT TURNS THE CAR OFF AT A STOP LIGHT AND THEN THE CAR WILL NOT RESTART. IT USUALLY NEEDS A JUMP. THE PROBLEM HAS BEEN HAPPENING FOR THREE YEARS IN THE WINTER. THE BATTERY HAS BEEN REPLACED FOUR TIMES. I HAVE TRACED TO THE ISSUE TO AN OVERLOAD OF THE ELECTRICAL SYSTEM. THE ALTERNATOR IS NOT CAPABLE OF POURING ALL OF THE DEVICES IN THE CAR AND THUS THE BATTERY DRAINS. IF I RUN THE HEATED SEATS AND STEERING WHEEL, THE BATTERY WILL DISCHARGE WITHIN 30 MINUTES EVEN IF THE CAR IS DRIVEN AT HIGHWAY SPEEDS. I HAVE BEEN STALLED IN THE MIDDLE OF INTERSECTIONS SEVERAL TIMES. THE AUTOSTART FEATURE NEEDS TO HAVE THE OPTION TO STAY DIS-ENGAGED WHEN THE CAR IS SHUT OFF. IT IS UNSAFE TO HAVE THE CAR FAILS TO START AT STOPLIGHTS OR WHEN TRYING TO PULL INTO TRAFFIC. THE ELECTRICAL SYSTEM IS DESIGNED IMPROPERLY. DO THE MATH. THE LOAD FROM THE ELECTRICAL ACCESSORIES, TWO HEATED FRONT SEATS, TWO REAR HEATED SEATS, HEATED STEERING WHEEL, HEATED MIRRORS, HEATED REAR WINDSHIELD WILL EASILY OVERLOAD THE POWER OF A STANDARD ALTERNATOR. THE VEHICLE NEEDS A LARGER ALTERNATOR AND A LARGER BATTERY (MAYBE DUAL) WITH ISOLATION SO IT CAN START AT STOPLIGHTS.

WE HAVE AN ONGOING ISSUE WITH OUR AUTO-IDLE FEATURE MALFUNCTIONING THAT BEGAN AT ABOUT 20,000 MILES. I HAVE WRITTEN A COMPLAINT HERE BEFORE, AS HAVE MANY OTHER 2016 PILOT OWNERS, HOWEVER NOTHING APPEARS TO HAVE BEEN DONE TO DATE. THIS IS A SIGNIFICANT SAFETY FEATURE WHEN THE AUTO-IDLE IS ENGAGED, FOOT IS TAKEN OFF THE BRAKE AND THE CAR COMPLETELY SHUTS OFF, OFTEN TIMES NOT STARTING BACK UP WITHOUT A JUMP START. THE CAR COMPLETELY SHUTS OFF, WARNING LIGHTS FLASH ALL OVER THE DASH AND NO MATTER WHAT YOU TRY THE CAR WILL NOT START BACK UP.THIS HAS HAPPENED TO MY WIFE WITH OUR 2 DAUGHTERS NUMEROUS TIMES. FORTUNATELY, THERE HASN'T BEEN AN ACCIDENT, BUT MY GREATEST FEAR IS ONE TIME THERE WILL BE. NATURALLY THIS ALWAYS SEEMS TO HAPPEN AT BUSY INTERSECTIONS. WE HAVE TAKEN THE VEHICLE INTO HONDA DEALERSHIP WHERE WE PURCHASED THE VEHICLE TOO MANY TIMES TO COUNT. THEY HAVE REPLACED THE BATTERY, REPLACED THE START/STOP SWITCH, CLEANED OUT MULTIPLE ERROR CODES. NOTHING HAS PROVIDED A PERMANENT FIX. WE JUST HAD TO HAVE OUR TRANSMISSION REPLACED AT 70,000 MILES! THE PROBLEM REARED IT'S HEAD AGAIN TODAY. THIS TIME MY WIFE HAD TO PRESS THE BRAKE, THE GAS PEDAL (BOTH WITH ALL HER MIGHT) AND PRESS THE START/STOP BUTTON AT THE SAME TIME. SOMETHING ISN'T RIGHT. I'M CONVINCED WE HAVE A LEMON, HOWEVER THE DEALER SEEMS TO THINK WE DON'T HAVE A CASE FOR THAT. HONDA HAS TO STEP IN AND TAKE ACCOUNTABILITY. THERE ARE FAR TOO MANY 2016 PILOT OWNERS HAVING THIS SAME ISSUE FOR HONDA NOT TO REALIZE THE VALID SAFETY CONCERN WE ALL HAVE. TAKE A LOOK AT PILOTEERS.ORG AND YOU WILL FIND A RIDICULOUSLY LONG LIST OF FRUSTRATED 2016 PILOT OWNERS ALL STRUGGLING WITH THE SAME PROBLEM. I AM URGING YOU TO TAKE ACTION TO CORRECT THIS PROBLEM. WE PURCHASED THIS VEHICLE FOR THE SAFETY FEATURES, HOWEVER "SAFE" ISN'T SOMETHING I FEEL KNOWING MY WIFE AND DAUGHTERS ARE IN THIS VEHICLE MULTIPLE TIMES PER DAY.

SEAMS YOU HAVE TO PUT THE TRANSMISSION IN PARK, AND PRESS THE START BUTTON (SOMETIMES 4-5 TIMES) BEFORE THE ENGINE STARTS. THIS IS NERVE RACKING AND DANGEROUS WHEN YOU ARE IN TRAFFIC- SAY AT A LIGHT, OR TRYING TO CROSS OVER ONCOMING TRAFFIC. THE TIME IS TAKES SOMETIMES TO RE-START THE ENGINE IS ABOUT 10-15 SECONDS. THIS PROBLEM IS INTERMITTENT. (DOESN'T ALWAYS HAPPEN). IT'S NOT THE BATTERY. I HAD A NEW BATTERY REPLACEMENT. I ALSO TRIED USING A TRICKLE CHARGER TO "TOP OFF" THE BATTERY INCASE IT WASN'T FULLY CHARGED. NO LUCK.

4PE25008 · 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 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.

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.
