APRIL 25,2019 DRIVING FROM ILLINOIS TO MS AT 75 MPH ON INTERSTATE AND APPLIED BREAK FOR UPCOMING CONSTRUCTION ZONE AND ALL WARNING SYSTEM LIGHTS FLASH THROUGH DASH AND CARE IMMEDIATELY STARTED SLOWING AND HAD NO ACCELERATION AT ALL. DISABLED ALL SAFETY FEATURES. ROAD DEPARTURE, BRAKE SYSTEM, ECT. PULLED OVER TO SIDE OF ROAD. RESTARTED SEVERAL TIMES AND ALL BUT TWO LIGHTS REMAINED ON SO CALLED DEALER. TWO LIGHTS REMAINED FLASHING AND CAR NOW SEEMED TO DRIVE OK SO COULD BE BROUGHT TO DEALER ABOUT 80 MILES AWAY. MEMPHIS ACURA DEALER WANTED TO KEEP CAR BECAUSE THEY INDICATED TRANSMISSION ISSUE BUT SINCE LIGHTS WERE RESET THEY SAID TAKE TO DEALER IF COMES ON AGAIN. MILEAGE 92,321. CALLED PEORIA IL ACURA DEALER A WEEK LATER TO CHECK ON ISSUE AND THEY SAID CODE WAS IMPLY A GLITCH. JULY 28, 2019 DRIVING 40 MPH IN TOWN AND ALL SAFETY LIGHTS CAME ON DASH. DISABLE ED ALL SAFETY FEATURES OF VEHICLE. RESTARTED SEVERAL TIMES AND EVENTUALLY ALL LIGHTS BUT TWO REMAINED ON. A FEW HOURS LATER ALL LIGHTS WERE NOW OFF. MAKE APPOINTMENT WITH PEORIA IL ACURA DEALER. MILEAGE 97,974. PEORIA DEALER SAID THE LIGHTS SOME ON BECAUSE WE NEEDED OUR 105,000 SERVICING WHICH INCLUDES ABOUT $1500 IN SERVICE LIKE PLUGS AND TIMING BELT. I CHALLENGE THEIR CLAIM (NOT AT THE MILEAGE) THAT ACURA WOULD CAUSE A SERIOUS SAFETY ISSUE FOR US ALL TO GET US TO DO THE SERVICE. THEY SAID UNFORTUNATELY THAT IS WHAT HAPPENS. NEXT WEEK HAD SPARK PLUGS REPLACED SINCE THEY SAID THAT CAUSED MISFIRE CODE. AUGUST 21 2019 AT 99,800 MILEAGE DRIVING 40 MPH ALL SAFETY LIGHTS ON CAR LOST POWER AND HESITATED AND THEN QUICKLY WENT OFF.

BEFORE SHARING THE DETAILS, YOU SHOULD KNOW THAT THIS COULD BE A DEADLY SAFETY MATTER. IF A TRANSMISSION FAILS AT HIGHWAY SPEEDS (OR ANY SPEED), THE VEHICLE LOSES POWER AND COULD VERY EASILY GET CRUSHED BY AN 18-WHEELER. A DRIVER AND/OR A WHOLE FAMILY COULD DIE. YOU SHOULD GO AFTER ACURA BEFORE SOMEONE HAS TO DIE AS A RESULT OF ACURA'S NEGLIGENCE. MY 2016 ACURA MDX HAD ITS FIRST TRANSMISSION REPLACEMENT IN OCTOBER 2016 AT AROUND 14,000 MILES AND ABOUT 18 MONTHS INTO OWNERSHIP. I HAD PURCHASED THE VEHICLE AS A BRAND NEW CAR FROM AN ACURA DEALER. I AM THE ONLY OWNER, AND IT HAS BEEN "BABIED" AND RECEIVED PROPER MAINTENANCE FROM ACURA DEALER SERVICE SHOPS ONLY. LEADING UP TO THE 1ST TRANSMISSION REPLACEMENT, THE VEHICLE WAS MAKING AWFUL "CHIRPING" NOISES UPON SLIGHT ACCELERATION AT SLOW SPEEDS. AFTER THE 1ST TRANSMISSION REPLACEMENT, ALL SEEMED FINE UNTIL RECENTLY. AT AROUND 38,000 MILES (SPRING 2019, STILL BARELY WITHIN THE 4 YEAR WARRANTY), THE VEHICLE BEGAN TO EXHIBIT IDENTICAL SYMPTOMS. AT 39,000 MILES, THE MDX RECEIVED ITS 2ND TRANSMISSION REPLACEMENT. ON THE VERY DAY THAT I PICKED IT UP FROM THE 2ND TRANSMISSION REPLACEMENT REPAIR WORK, THE MDX STARTED MAKING FAR WORSE NOISES THAN BEFORE THE REPAIR WORK. IT IS BACK IN THE SHOP AGAIN AND ACURA SEEMS TO BE AT A COMPLETE LOSS FOR HOW TO FIX IT PROPERLY FOR A 3RD TIME! THERE ARE MANY ACURA/HONDA TECHNICAL SERVICE BULLETINS ABOUT TRANSMISSION ISSUES ON THESE AND ACURA/HONDA-RELATED VEHICLES WHICH USE THE SAME TRANSMISSION. IT IS CLEARLY A WELL-KNOWN PROBLEM PUTTING COUNTLESS DRIVERS/PASSENGERS AT PHYSICAL RISK OR FINANCIAL RISK.

CAR ELECTRICAL ACTIVATED WHEN START BUTTON WAS PUSHED BUT IT WASN'T CLEAR IF ENGINE WAS RUNNING. CAR WOULD NOT "TURN OFF" OR LOCK. MANY ERROR MESSAGES CAME ACROSS DASH AND CAR WAS NOT PROPERLY RECOGNIZING FOBS. AN ACURA SERVICE CENTER WAS CALLED AND WE WERE TOLD OUR ONLY OPTION WAS TO DISCONNECT BATTERY LEADS OR LET THE CAR RUN UNTIL THE BATTERY DIED. MANY HOURS LATER THE BATTERY DIED. WHEN THE ACURA SERVICE TRUCK CAME TO GET US THEY COULDN'T EVEN GET THE CAR INTO NEUTRAL AFTER CHARGING THE BATTERY AND WHEEL TRUCK HAD TO BE CALLED. THE DEALERSHIP HAD THE CAR FOR WEEKS AND WAS NOT ABLE TO DETERMINE THE PAUSE. WE HAVE MULTIPLE VIDEOS OF THE INCIDENT. NOTE THAT THE CAR WAS NOT IN ACCESSORY MODE AND THE BEHAVIOR IS INCONSISTENT WITH ACCESSORY MODE.

VEHICLE HESITATES FROM A STOP. USUALLY FIRST DRIVE OF THE DAY. INTERMITTENT BUT BECOMING MORE FREQUENT AND AT RANDOM TIMES. SOMETIMES, AFTER DRIVEN AND LEAVING A STOP SIGN/LIGHT OR ENTERING TRAFFIC. ACURA CLAIMS THEY HAVE NEVER DUPLICATED PROBLEM IN MY VEHICLE AND NO DTCS SET. OPERATES NORMAL. RECENTLY RETIRED DEALER SERVICE MANAGER TOLD ME IT HESITATED TWICE FOR HIM (NEVER PUT IT IN WRITING), ONCE WITH COMPUTER ATTACHED. ACURA TECH LINE WAS SENT DATA AND RESPONDS OPERATION NORMAL. ACURA DISTRICT PARTS AND SERVICE MANAGER STATES ORDINARY OPERATIONS OF ALL SYSTEMS INCLUDING TRANSMISSION. HE STATES TIME LAG BETWEEN THE TIME STARTED, SHIFTING TRANSMISSION INTO GEAR, SENSORS SENDING AND RECEIVING DATA AND VEHICLE RESPONDING. THIS IS A DRIVE BY WIRE SYSTEM THAT INVOLVES A COMPUTER AND SENSORS AND SOMETIMES THEY COMMUNICATE SLOWER IT APPEARS THERE IS A HESITATION. THIS IS A NORMAL PROCESS OF THE VEHICLE. WHEN I PRESS ACCELERATOR PEDAL, AFTER SHIFTING INTO DRIVE, VEHICLE DOES NOT MOVE, RPM DOES NOT CHANGE. SUDDENLY AND AGGRESSIVELY, THE VEHICLE LURCHES FORWARD, I THINK CORRESPONDING TO THE ACCELERATOR POSITION AT THE TIME, AND THE RPM SURGES. I THINK THE VEHICLE DRIVES AND OPERATES FINE AFTER IT IS MOVING. IT IS A SERIOUS SAFETY HAZARD THAT COULD CAUSE ME TO RUN INTO SOMEONE OR BE HIT BY SOMEONE. ACURA'S DENIAL OF THE PROBLEM DOES NOT MAKE IT GO AWAY. IF THE HESITATION WAS NORMAL, EVERY VEHICLE LIKE MINE WOULD HESITATE. IF IT WERE NORMAL, THEY WOULD BE ABLE TO DUPLICATE IT. IT IT WERE NORMAL, IT WOULD HESITATE EVERY TIME I DRIVE IT. IF THE HESITATION WAS NORMAL, IS IT NOT NORMAL WHEN IT DOESN'T HESITATE? HESITATION BEGAN WITHIN WEES OF PURCHASING FROM THE DEALER. CURRENTLY HAVE 38000+ MILES. HAVE LITERALLY CHANGED THE WAY WE OPERATE THE VEHICLE ANTICIPATION IT WILL HESITATE. SEVERAL VIDEOS SHOWING RPM SURGE WITH ACCELERATOR FULLY DEPRESSED THAT ARE TOO LARGE TO UPLOAD.

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.

Status: open (inferred from source dates) · Engine And Engine Cooling:engine; Engine And Engine Cooling:engine:crank/camshaft Position Sensor; Engine And Engine Cooling:engine:engine Control Module (ecu/ecm):software; Engine And Engine Cooling:engine:hard Parts Internal/mechanical

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.
