I BACKED OUT OF A PARKING SPACE AT WORK, AND WHEN I BRAKED AND PRESSED THE DRIVE BUTTON, THE CAR DID NOT SHIFT. AFTER SEVERAL TRIES THE CAR WENT INTO DRIVE. I DROVE OUT OF THE PARKING LOT ONTO A SIDE STREET. HOWEVER, AFTER ACCELERATING UP TO THE 20 MPH LIMIT, THE CAR APPARENTLY JUMPED DOWN TO 2ND AND HAD TO BE SHIFTED BACK INTO DRIVE. AFTER A BLOCK OR TWO, I STOPPED AT AN INTERSECTION, WAITED FOR THE LIGHT TO CHANGE AND ACCELERATED AFTER TURNING LEFT ONTO A CITY STREET. AFTER ABOUT SIX BLOCKS I BRAKED, TURNED LEFT, THEN RIGHT IN TO A PARKING LOT. I CONTINUED ACROSS THE PARKING LOT AT ABOUT 10 MPH UNTIL I NEARED A PARKING SPACE. AS I BEGAN THE LEFT TURN INTO THE SPACE, I APPLIED THE BRAKE AND SLOWLY ENTERED THE SPACE. I CONTINUED TO TURN AT A SLOW SPEED WITH LIGHT BRAKE PRESSURE WHEN SUDDENLY THE CAR SURGED FORWARD AND CRASHED INTO THE FRONT OF A PARKED VEHICLE, DAMAGING THE FRONT OF BOTH VEHICLES.

THEN IT SEEMS TO GET STUCK IN THE LOWER GEAR AND FEELS LIKE AS IF THE GEARS ARE GRINDING. I CAN ALSO FEEL THE GEARS GRINDING IN THE ACCELERATION PEDAL. AT THIS POINT, I AM ABLE TO SMELL METAL BURNING THROUGH THE AIR CONDITIONING - SEEMS LIKE THE TRANSMISSION IS GETTING OVERHEATED.

WE BOUGHT A NEW 2016 HONDA PILOT AWD EX-L IN OCTOBER 2016 AND ARE EXPERIENCING SOME PRETTY SERIOUS TRANSMISSION ISSUES. THE FIRST INCIDENT HAPPENED ABOUT A MONTH AGO BEFORE THE VEHICLE EVEN HAD 900 MILES ON IT AND IT HAS RE-OCCURRED NUMEROUS TIMES SINCE THEN AND WE ONLY HAVE 2,000 MILES ON IT. IT APPEARS THAT IF YOU DECELERATE RATHER QUICKLY FROM LET'S SAY 50 MPH+ TO ZERO, THAT WHEN YOU RE-START FROM ZERO, THE TRANSMISSION IS ALL OUT OF SORTS. WHEN YOU HIT THE GAS AT ZERO (AFTER THE FAST DECELERATION) THE VEHICLE WILL BE VERY HESITANT/SLOW TO START (ALMOST AS IF YOU'RE STARTING IN A HIGHER GEAR THAN 1ST) AND THEN WHEN YOU GET TO ABOUT 25-30 MPH, THE VEHICLE WILL SLAM INTO THAT GEAR AND SHAKE THE ENTIRE VEHICLE. THAT 'SLAMMING INTO GEAR' ISSUE WILL CONTINUE EVERY TIME YOU DROP DOWN OR ACCELERATE TO THAT 25-30 MPH RANGE DURING THAT DRIVING SESSION. THE ONLY WAY TO GET THE ISSUE TO STOP DURING THAT DRIVING SESSION, IS TO STOP THE VEHICLE AND RE-START THE ENGINE. IT'S ALMOST LIKE IT RESETS THE TRANSMISSION OR THE COMPUTER THAT RUNS THE TRANSMISSION' THERE ARE NO CHECK ENGINE LIGHTS/WARNINGS THAT COME ON AND IT'S A HARD ISSUE TO DUPLICATE, BUT THE ONLY THING THAT SEEMS TO MAKE IT OCCUR SOMETIMES IS FAST DECELERATION FROM A HIGH SPEED DOWN TO ZERO (I.E. COMING OFF AN OFF-RAMP AND HITTING A STOP LIGHT, OR DRIVING ON A 50MPH TYPE ROAD AND THEN HITTING A STOP LIGHT). THERE'S OBVIOUSLY A MAJOR TRANSMISSION FLAW AND THE CONTINUED "SLAMMING INTO GEAR" WHEN THIS ISSUE OCCURS, CAN ONLY BE DOING MORE DAMAGE TO THE TRANSMISSION AND FEELS LIKE THE ENGINE IS ON THE VERGE OF LOCKING UP. *TR

ON SEPTEMBER 2, 2016 WHILE ASCENDING UP A WINDING 2-LANE HIGHWAY (HIGHWAY 18) TO LAKE ARROWHEAD, OUR YEAR OLD 2016 HONDA PILOT TOURING (WITH A ZF 9-SPEED TRANSMISSION) BEGAN DECELERATING RAPIDLY FROM 55 MPH TO 20 MPH. MY WIFE WAS DRIVING WITH OUR 4 CHILDREN AND WAS ABLE TO PULL TO THE SIDE OF THE ROAD. SHE PULLED OVER, TURNED THE CAR OFF AND A SHERIFF STOPPED. THE SHERIFF RECOMMENDED SHE TRY TO CONTINUE TO DRIVE TO GET THE CAR OFF THE HIGHWAY SINCE THEY WERE IN A VERY DANGEROUS AREA. MY WIFE STARTED THE CAR AND PROCEEDED TO ASCEND TO THE NEAREST OFF RAMP AND WHEN NUMEROUS WARNING LIGHTS CAME ON AND THE CAR RAPIDLY DECELERATED ONCE AGAIN. THIS IS THE SECOND TIME SOMETHING LIKE THIS HAS OCCURRED. IN DECEMBER 2015, A SIMILAR ISSUE OCCURRED WHILE DRIVING STRAIGHT UP A HILL ON A 4 TO 5 LANE FREEWAY FROM SAN DIEGO TO LOS ANGELES. IN THAT CASE, THE 2016 HONDA PILOT JERKED VIOLENTLY BEFORE DECELERATING. MY WIFE IMMEDIATELY PULLED THE CAR TO THE SIDE OF THE FREEWAY AND HAD THE CAR TOWED TO PACIFIC HONDA. HONDA DETERMINED THAT OUR PILOT WAS UNSAFE TO DRIVE AND NEEDED AN ENTIRELY NEW TRANSMISSION AND REPLACED THE TRANSMISSION IN THE 4-MONTH OLD VEHICLE. HONDA REASSURED US THE CAR WAS NOW SAFE. IT IS NOW 8 MONTHS LATER (OUR CAR IS JUST 1 YEAR OLD), AND OUR CAR IS NOW SITTING AT ROCK HONDA IN FONTANA, CALIFORNIA. HONDA IS NOW DETERMINING THE NEXT COURSE OF ACTION. WE HAVE THE NAME AND BADGE NUMBER OF THE SHERIFF WHO ASSISTED MY WIFE IF HELPFUL. THIS IS A VERY DANGEROUS SITUATION AND SHOULD BE RECTIFIED IMMEDIATELY.

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.
