I WAS TRAVELING ON A TWO LANE HIGHWAY AT A SPEED OF AROUND 75MPH. I NEEDED TO SLOW DOWN SO PULLED MY FOOT OFF ACCELERATOR AND SLOWED BY ABOUT 10MPH. WHEN I WENT TO ACCELERATE AGAIN I HAD NO POWER AND THE CAR BEGAN TO DECELERATE FOR THE NEXT 10-15 SECONDS. I HAD NO POWER AND HAD A CAR COMING IN CLOSE BEHIND ME AND A BIG RIG TO MY RIGHT. THIS WAS A DANGEROUS SITUATION. THE CAR FINALLY KICKED INTO GEAR AFTER SEVERAL ATTEMPTS TO ACCELERATE. AFTER TAKING IT TO HONDA TO BE CHECKED THEY SAID THEY COULD NOT "DUPLICATE" THIS NOR FIND ANYTHING IN THE LOG BUT HONDA HAS PLACED AN EXTENDED WARRANTY ON THE TRANSMISSION. AN EXTENDED WARRANTY ISN'T GOING TO SAVE OUR LIVES IF THIS SITUATION OCCURS AGAIN. HONDA NEEDS TO ADDRESS THIS ISSUE.

VEHICLE RANDOMLY CUTS POWER TO ENGINE. WHILE VEHICLE IS IN MOTION, STABILITY CONTROL SYMBOL FLASHES WHEN ACCELERATOR IS PRESSED AND POWER IS CUT FROM THE ENGINE CAUSING VEHICLE TO SLOW. RELEASING ACCELERATOR ALLOWS VEHICLE TO COAST AND STABILITY CONTROL SYMBOL ON DASH GOES AWAY. AS SOON AS ACCELERATOR IS PRESSED AGAIN, STABILITY CONTROL SYMBOL FLASHES AND POWER IS ONCE AGAIN CUT FROM ENGINE. VERY SCARY ON FREEWAY. PULLING OVER AND PUTTING INTO PARK AND DRIVE DOES NOT CORRECT ISSUE. VEHICLE MUST BE TURNED OFF AND TURNED BACK ON TO RESET. IMAGINE HOW SCARY THIS WILL BE DOING 70 ON THE FREEWAY AND POWER BEING CUT FROM THE ENGINE SURROUNDED BY TRAFFIC AND UNABLE TO GET TO THE SHOULDER TO TURN THE VEHICLE OFF AND RESET THE SYSTEM.

I HAD PULLED OUT OF A PARKING PLACE AND WAS WAITING IN THE TRAFFIC LANE TO EXIT THE AREA. THERE WERE TWO CARS IN FRONT OF US. THE CARS WERE STOPPED. I WAS APPROXIMATELY 20-25 FEET BEHIND THE CAR IN FRONT OF ME. I TOOK MY FOOT OFF THE BRAKE IN MY CAR TO LET IT IDLE FORWARD. AS I APPROACHED THE YUKON I REAPPLIED THE BRAKE. THE CAR ACCELERATED TO WHAT SOUNDED LIKE FULL RPM'S AND I APPLIED THE BRAKES AS HARD AS I COULD AND NOTHING HAPPENED. THE CAR SLAMMED INTO THE YUKON WITH SUCH AN IMPACT THAT BOTH FRONT AIRBAGS DEPLOYED. THE DRIVER SIDE AIRBAG HIT ME IN THE FACE. THE PASSENGER AIRBAG DID NOT REACH MY WIFE IN THE PASSENGER SEAT. SHE IMMEDIATELY EXPERIENCED SEVERE CHEST PAIN AND RAPID HEART BEAT. BYSTANDERS CALLED 911 AND TWO PARK RANGERS ARRIVED IN APPROX. 15-20 MINUTES. THE RANGERS FINISHED TAKING PICTURES AND ASKED ME TO PULL IN TO A PARKING SPOT OUT OF THE TRAVEL LANE OF THE PARKING LOT. I STARTED THE CAR AND PROCEEDED SLOWLY AND TURNED INTO A PARKING SPOT. AS I APPLIED THE BRAKE TO PARK, THE SAME PHENOMENON OCCURRED AGAIN. THE CAR ACCELERATED FORWARD OVER A CURB AND WALKWAY AND STRUCK A PEDESTRIAN BEFORE COMING TO A STOP ON A RETAINING WALL. I DESPERATELY TRIED TO STOP THE CAR WITHOUT SUCCESS. THE EMS WAS THERE SHORTLY AFTER THIS OCCURRENCE. A RANGER ASKED ME HOW FAST I WAS MOVING AND I STATED I HAD NO IDEA. I ASKED HIM TO ASK THE RANGER WHO WAS RIGHT BEHIND ME AND HE SAID 5 MPH. I EXITED THE VEHICLE AFTER THEY TRANSPORTED THE PEDESTRIAN ON THE BACKBOARD.THE AMBULANCE WAS READY TO TAKE MY WIFE TO THE HOSPITAL SO I APPROACHED THE PARK RANGER AND TOLD HIM THAT I NEEDED TO RIDE IN THE AMBULANCE WITH MY WIFE.

MY FAMILY TRAVELED IN THIS VEHICLE TO CARLSBAD LAST WEEK FOR VACATION, INCLUDING MYSELF, MY WIFE, OUR 13 YEAR OLD DAUGHTER AND 11 YEAR OLD SON. THE VEHICLE WORKED PERFECTLY UNTIL WE WERE ON OUR WAY HOME SATURDAY, JULY 22, 2017. WE WERE ON I-10 APPROXIMATELY 1 HOUR EAST OF PHOENIX IN THE RIGHT LANE WITH THE CRUSE SET AT THE 75MPH SPEED LIMIT. THERE WERE NO CARS IN FRONT OF US FOR AT LEAST A MILE. ALL THE SUDDEN, WITHOUT ANY WARNING WHATSOEVER, NEARLY ALL THE VEHICLE SYSTEM LIGHTS CAME ON AND THE VEHICLE SLOWED AT AN EMERGENCY RATE DOWN TO APPROXIMATELY 40MPH IN ABOUT 2 SECONDS. I IMMEDIATELY HIT 'CANCEL' ON THE CRUISE AND STEPPED ON THE GAS, BUT THE VEHICLE CONTINUED TO SLOW QUICKLY. I IMMEDIATELY STARTED TO MOVE TO THE SHOULDER OF THE ROAD AND NOTICED THE 18 WHEEL TRACTOR TRAILER BEHIND US MAKE AN EMERGENCY SWERVE TO THE LEFT AND MISSED HITTING US BY INCHES. WE WERE NEARLY INVOLVED IN AN ACCIDENT THAT COULD HAVE EASILY BEEN FATAL. ALL THIS TOOK PLACE IN ABOUT A 5-10 SECOND TIMEFRAME. AFTER STOPPING ON THE SHOULDER OF THE ROAD I MADE NOTE THAT THE VEHICLE WAS SHOWING A TRANSMISSION PROBLEM, AN EMISSIONS PROBLEM, AN AWD PROBLEM AND I THINK JUST ABOUT EVERY OTHER ISSUE LIGHT WAS LIT UP. I TRIED TO GET THE VEHICLE BACK ON THE ROAD, BUT IT WOULD NOT GO ANY HIGHER THAN 3RD GEAR AND THE DASH KEPT INDICATING A TRANSMISSION AND AWD PROBLEM. I PULLED OVER AGAIN AND TURNED THE VEHICLE OFF AND BACK ON. AT THAT POINT THE ONLY INDICATOR LIGHT THAT LIT UP WAS THE EMISSION SYSTEM PROBLEM (SEE ATTACHED PICTURE). I REENTERED THE INTERSTATE AND THE TRANSMISSION WAS WORKING PROPERLY AGAIN. WE STOPPED AT THE NEXT GAS STATION AND FILLED THE GAS TANK AND UPON RESTARTING THE ENGINE THE EMISSION LIGHT WAS STILL ON. WE CAREFULLY DROVE HOME AT 65'70MPH. THE FOLLOWING DAY (SUNDAY), THE EMISSION LIGHT WAS NO LONGER ON.

THIS IS A FOLLOW UP TO COMPLAINT 10881962 IN WHICH ONE OF MY FEARS HAS COME TO FRUITION. I WAS DRIVING MY CAR IN THE NORMAL MODE (ACC AND LKAS DISABLED) ON A NORMAL TWO LANE PAVED ROAD WHEN THE CAR IN FRONT OF ME MADE A SLOW RIGHT TURN. I WAS NOT FOLLOWING VERY CLOSELY AND CAME TO A COMPLETE STOP ON MY OWN TO AVOID RUNNING INTO THE OTHER CAR. I STOPPED ABOUT 15 FEET AWAY FROM THE OTHER CAR. THE OTHER CAR THEN COMPLETED THE TURN TO THE EXTENT THAT THE OTHER CAR WAS NO LONGER IN THE WAY OF ME DRIVING FORWARD IN A STRAIGHT LINE. WHEN I PUSHED THE GAS TO THEN PROCEED THE COLLISION MITIGATION SYSTEM STARTED FLASHING THE "BRAKE" MESSAGE AND PRODUCING AN AUDIBLE WARNING. AT THIS POINT I WAS POSSIBLY GOING 10 MPH AGAIN. AFTER VERIFYING THAT THERE WAS DEFINITELY NOT ANYTHING IN MY WAY, I KEPT APPLYING THE GAS. MY CAR THEN STARTED BRAKING ON ITS OWN, AT WHICH POINT I PUSHED THE GAS HARDER TO PRESUMABLY OVER-RIDE THE BRAKING. A MOMENT OR TWO LATER, MY CAR THEN MADE A SUDDEN AND HARD BRAKE ON ITS OWN THAT BROUGHT MY CAR TO A COMPLETE STOP, DESPITE THE FACT THAT I WAS PUSHING HARD ON THE GAS. THE OTHER CAR THAT HAD TURNED WAS WELL CLEAR OF THE LANE BY THIS POINT, AND WAS EASILY 1 FT AWAY FROM MY PATH OF TRAVEL WHEN I STARTED ACCELERATING IN THE FIRST PLACE. MY ONLY EXPLANATION IS THAT THE COLLISION MITIGATION SYSTEM WAS CONFUSED BY THE LACK OF A SHOULDER LANE MARKER (ONLY A RAISE CEMENT CURB WAS PRESENT) AND SOMEHOW THOUGHT THE CAR WAS STILL IN THE "ROAD." IN EITHER CASE, THE SYSTEM MALFUNCTIONED TO THE POINT THAT MY CAR WAS SUDDENLY BROUGHT TO A COMPLETE STOP, AND THE CAR BEHIND ME VERY NEARLY REAR-ENDED ME IN A SITUATION WHERE I HAD ALREADY COME TO A STOP, AND THE OBSTACLE IN FRONT OF ME HAD CLEARED / CONTINUED TO BECOME INCREASINGLY MORE CLEAR OF MY PATH. THE SITUATION WAS DANGEROUS AND CLEARLY MISINTERPRETED BY MY CAR.

MY CAR HAS A VARIETY OF DANGEROUS BEHAVIORS IN THE DRIVER ASSIST FUNCTIONALITIES THAT COULD EITHER CAUSE OR FAIL TO PREVENT AN ACCIDENT. I HAVE ONLY DRIVEN IT 2,000 MILES BUT OBSERVED THESE MANY TIMES. I REPORTED THESE TO THE DEALER AND WAS TOLD THE CAR WAS FINE. ADAPTIVE CRUISE CONTROL ISSUES: - FAILS TO DETECT VEHICLES IN ODD SITUATIONS, SUCH AS A TRUCK WHERE THE REAR OF THE BODY PROTRUDES OUT FROM THE REAR WHEELS, AS IF THE RADAR IS ONLY AT GROUND LEVEL, OR IF A VEHICLE IS DRIVING IN MY LANE BUT ONE TIRE IS IN THE OTHER LANE, OR A WIDE LOAD WHICH OCCUPIES ALL OF THE ADJACENT LANE AND HALF OF MY LANE, OR A "BOBTAIL" TRUCK. - AFTER AN EMPTY STRETCH, UPON COMING UP TO A SLOWER CAR, RATHER THAN SLOW GRADUALLY BY EASING OFF THE GAS, THE CAR WILL GET VERY CLOSE TO THE CAR AND THEN RAPIDLY BRAKE, CAUSING DRIVERS BEHIND ME TO NEARLY REAR-END ME. COLLISION MITIGATION: - ALL OF THESE TRIGGER "BRAKE" MESSAGES TO BE DISPLAYED, WHICH IS JUST 1 STEP BEFORE THE BRAKES BEING AUTO-APPLIED, WHICH COULD CAUSE ME TO BE REAR-ENDED. - FALSE ALARMS WHILE MERGING FROM LEFTHAND ONRAMPS WHERE A PENDING COLLISION WITH THE JERSEY BARRIER IS DETECTED - FALSE ALARMS BY THE HILLS ADJACENT TO THE ROAD WHEN GOING AROUND A SHARP TURN ON BACK ROADS - FALSE ALARMS WHEN CRESTING A HILL WITH A CURVE AFTER THE HILL AND IT THINKS AN ONCOMING CAR WILL BE HIT, BECAUSE IT CAN'T SEE THE LANE MARKINGS PAST THE HILL LANE KEEP ASSIST: - PARTIALLY GOES INTO EXIT RAMPS ON ITS OWN IF IN THE RIGHT LANE, CAUSING OTHER DRIVERS TO THINK I AM LEAVING THE LANE AND START TO MERGE THEMSELVES - IS CONFUSED BY LINES OF TAR AND WILL DEPART THE LANE ON ITS OWN - OFTEN "FIGHTS" WITH THE LANE DEPARTURE MITIGATION AROUND CORNERS - TRIES TO PREVENT ME FROM GIVING OTHER VEHICLES SOME BUFFER WHEN PASSING THEM, IF THEY ARE WIDER OR DRIFTING TOWARD ME. - DOES NOT ALERT WHEN IT STOPS BEING ABLE TO DETECT THE LINES

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.

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.
