THE BIGGEST ISSUE IS A 'KEYLESS START SYSTEM' ISSUE. MESSAGE IS ON DASHBOARD CONSTANTLY. LOOKING AT COMPLAINT BOARDS FOR 2016 HONDA PILOT, I'M SHOCKED THIS ISN'T A RECALL. SEEMS TO BE A COMMON PROBLEM. AND A WORRY THAT CAR WILL SUDDENLY STOP WHILE ON HIGHWAY. ALSO THE CAR HAS A CONSTANT 'REV, REV, REV' PULLING AT TIMES WHILE DRIVING. ALWAYS AN ISSUE WHEN BEHIND SOMEONE AND YOU WORRY IT WILL REV AND JUMP AHEAD AND HIT CAR IN FRONT OF YOU. TOOK IT INTO DEALERSHIP AND THEY SUPPOSEDLY FIXED IT BUT STILL NOT FIXED. AGAIN LOOKING AT BOARDS, THIS SEEMS TO BE AN ISSUE.

MY CAR WILL DIE AFTER BEING STOPPED (EX. AT A RED LIGHT, STOP SIGN) AND WILL NOT RESTART RIGHT AWAY. SOMETIMES IT DOESN'T DIE COMPLETELY. WHEN IT DOES YOU ARE UNABLE TO PUT THE CAR INTO PARK OR ENGAGE THE EMERGENCY LIGHTS. THIS HAS HAPPENED WHERE WE WERE STOPPED AT A RED-LIGHT AND THE CAR DIED AND WOULD NOT RESTART. A CAR BEHIND US WAS APPROACHING THE LIGHT AND SAW THAT IT WAS GREEN, QUICKLY CAME UP BEHIND US HONKING THEIR HORN AND LUCKY WAS ABLE TO MOVE TO THE OTHER LANE TO AVOID HITTING US. THIS SEAMS TO HAPPEN WHEN WE FORGET TO TURN OFF THE AUTO IDLE STOP. THIS IS SOMETHING YOU HAVE TO PUSH EVERYONE YOU START THE CAR. I TOOK THE CAR TO THE DEALER THEY PUT IN A NEW TRANSMISSION AND CHANGED THE TIMING BELT. PREVIOUSLY I HAD THE CARS FUEL INJECTORS REPLACED. AFTER ALL THIS WORK THE CAR IS STILL DYING AND IT IS HAPPENING MORE FREQUENTLY. THE DEALERSHIP SAYS THEY HAVE HEARD OF THIS PROBLEM BUT DON'T KNOW OF A FIX YET.

WHEN ACCELERATING FROM A STOP OR LOW SPEEDS THERE IS A NOTICEABLE HESITATION BEFORE THE VEHICLE WILL BEGIN TO ACCELERATE. IT IS ALMOST AS IF THE VEHICLE IS HUNTING FOR THE PROPER GEAR AND ENGINE RPM BEFORE BEGINNING TO MOVE. ON OCCASION IT WILL ALSO SURGE FORWARD ONCE THE TRANSMISSION ENGAGES. IT IS QUITE UNSAFE WHEN PULLING OUT INTO TRAFFIC ESPECIALLY ACROSS TRAFFIC.THIS HAS BEEN AN OCCURRENCE SINCE THE VEHICLE WAS NEW. WE THOUGHT MAYBE IT HAD TO DO WITH THE "ECO" MODE BUT HAVE DETERMINED IT HAPPENS WITH OR WITH OUT THIS MODE ON. WE HAVE BROUGHT THIS TO THE ATTENTION OF THE DEALER WE PURCHASED FROM AND THEY SAID THEY HAD NO RESOLUTION FROM HONDA.

THE TRANSMISSION HAS SUBTLE BUT CONCERNING JERKING BETWEEN 10-30MPH, ESPECIALLY WHILE ACCELERATING. THIS CAN BE GETTING ON THE FREEWAY, DRIVING STRAIGHT DOWN THE STREET OR GOING UP HILLS. I NOTICED IT IS WORSE WHEN GOING UP A SLOPED SURFACE. UPON HAVING A TRANSMISSION SPECIALIST DISMANTLE AND ANALYZE, I WAS INFORMED THE TORQUE CONVERTER AND OTHER ELEMENTS OF THE TRANS WERE FAILING AND FALLING APART. AT UNUSUALLY LOW MILEAGE, THE TRANSMISSION WAS HEATING UP VERY HIGH BECAUSE OF THE ISSUE, DARKENING THE FLUID AND CARRYING ELEMENTS OF THE FAILING CONVERTER ETC INTO OTHER PARTS OF THE TRANSMISSION. THIS REQUIRES A FULL TRANS REBUILD WHICH COSTS RANGE FROM 4-7K DEPENDING ON WHERE YOU TAKE IT. THIS IS AN ISSUE THAT A BASIC MECHANIC MAY MISS, BUT OWNERS WILL NOTICE FOR THIS YEAR/MODEL OVER THE LONG TERM. POTENTIAL DANGERS REPORTED ARE VERY CONCERNING, SO WE CHOSE TO HAVE THE TRANS FULLY REBUILT FOR THE SAFETY OF OUR FAMILY. BASED OFF MY RESEARCH, HUNDREDS OF OTHER COMPLAINTS EXIST ONLINE FOR THIS YEAR/MODEL DESCRIBING THE SAME EXACT EXPERIENCE. HONDA SHOULD BE RECALLING THEIR TRANSMISSION FOR THE 2016 HONDA PILOT.

I NOTICED THE CAR STARTED JERKING BETWEEN 30-50 MPH. THE RPM'S WOULD ALSO PULSE AT THE SAME TIME. I TOOK IT TO THE DEALER AND OF COURSE THE WARRANTY WAS OUT. THEY 'RECOMMEND A TRANSMISSION FLUID FLUSH AND THE INTAKE NEEDED CLEANING.' SUPPOSEDLY THE INTAKE IS DIGITAL AND IT AFFECTS THE TRANSMISSION. THEY FOUND THE TRANSMISSION OIL WAS BURNT DUE TO HIGH TRANSMISSION TEMP. ALL OF THIS WAS DONE ON MARCH 10 2020. AUGUST 17 2020 I TOOK IT BACK TO HONDA WITH WORSE PROBLEMS WITH THE TRANSMISSION. THIS TIME WHEN I WOULD PUT THE CAR IN REVERSE IT WOULD JERK INTO GEAR. MY WIFE SAYS WHILE DRIVING IT JERKS HARD AT RANDOM TIMES. THIS TIME THEY RECOMMEND ANOTHER TRANSMISSION FLUSH BECAUSE 1/3 OF THE OIL WAS STILL BAD. APPARENTLY AFTER READING ON THIS SITE, THIS IS AN ISSUE WITH THE 2016 HONDA PILOT TRANSMISSIONS. IS IT GOING TO TAKE A COUPLE OF DEATHS BEFORE HONDA ACCEPTS RESPONSIBILITY THAT THE TRANSMISSION IS FAULTY?

ON AUGUST 9, 2020, I WAS DRIVING, AT 75, WITH THE CRUISE CONTROL ON, I NEEDED EXTRA SPEED TO PASS A VEHICLE ON THE RIGHT SIDE, I PRESSED THE GAS PEDAL WITH THE CRUISE CONTROL STILL ENGAGED AND THE VEHICLE WENT INTO A POWER DOWN MODE WITH THE DASHBOARD FLASHING CODES AND THEN WENT BLANK. THE ENGINE DOWNSHIFTED AND THE ENGINE SPEED INCREASED TO 7,000 RPM. THE CAR COMPLETELY SHUT DOWN, AT 75 MPH, AND RESTARTED WITH THE DASHBOARD LIGHTING UP AGAIN. AFTER PANICKING, TRIED TO GIVE THE CAR GAS AND IT WOULD NOT GO. NOW AT 65 MPH, I PULLED OVER TO THE RIGHT LANE AND COASTED DOWN TO 40 MPH AND THE CAR STARTED HAVING POWER AGAIN. WE PULLED OVER AND SHUT OFF THE CAR. I RESTARTED THE CAR AND AN "EMISSIONS SYSTEM PROBLEM" WAS DISPLAYED ON THE DASHBOARD. THE CAR HAS 56,217 MILES ON IT. I HAVE A VIDEO OF THIS PROBLEM. THE DASHBOARD WARNING SYSTEM DISPLAYED THE FOLLOWING CODES, "EMISSIONS SYSTEM PROBLEM"; "ALL WHEEL DRIVE SYSTEM PROBLEM"; "TRANSMISSION SYSTEM PROBLEM" AND THE "D" DRIVE SYMBOL WAS FLASHING ON & OFF. AN EARLIER INCIDENT, MAY 6, 2020, HAPPENED TO MY WIFE WHILE DRIVING THE CAR IN LOCAL TRAFFIC. DRIVING AT 50 MPH, THE ENGINE SPEED INCREASED AND THE CAR WOULD NOT MOVE FORWARD. SHE ALSO TRIED TO GIVE MORE GAS AND THE CAR WOULD NOT MOVE. SHE STOPPED ON THE SIDE OF THE HIGHWAY AND SHUT OFF THE CAR. SHE RESTARTED THE CAR AND PULLED OFF THE HIGHWAY. SHE CALLED THE HONDA DEALERSHIP AND IMMEDIATELY TOOK THE CAR INTO THE SERVICE CENTER. THEY TOOK THE CAR AND DROVE IT AROUND THE BUILDING AND SAID THEY CHECKED THE COMPUTER FOR CODES, BUT NONE WHERE PRESENT. AT THIS TIME THE CAR ONLY HAD 55,000 TO 56,000 MILES. THEY TOLD HER NEXT TIME THIS HAPPENS TO TAKE A VIDEO SO THEY CAN SEE WHAT HAPPENS TO THE CAR. TAKE A VIDEO WHILE DRIVING A CAR THAT IS SHUTTING DOWN IS THEIR SUGGESTION....

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.
