MY VEHICLE JUST DROVE 20K MILES, I AM GETTING A POPUP "KEYLESS START SYSTEM PROBLEM" VERY FREQUENTLY WHEN EVER I START MY CAR. MINE IS 2016 HONDA PILOT TOURING AWD. I WENT TO DEALER, FIRST DAY HE RESET SOME CODE AND THE WARNING MESSAGE WENT OFF. BUT IMMEDIATELY ON NEXT DAY IT CAME AGAIN. I WENT TO DEALER AGAIN AND THEY DID 2 HOURS OF INVESTIGATION AND TOLD , THEY WILL REPLACE THE BATTERY AND THEY ORDERED A PART. YESTERDAY MY PART WAS READY AND THEY SAID THEY HAVE REPLACED THE PART AND REPLACED THE FOB BATTERIES. THE WARNING WAS WENT OFF ON THAT DAY BUT, IT CAME AGAIN TODAY. I AM TOTALLY FRUSTRATED WITH THIS BEHAVIOR. WHEN I SEARCH ON THE FORUMS MOST OF THE PILOT CUSTOMERS HAD THE SAME ISSUE AND THEY HAVE REPORTED IN THIS FORUM.

I AM GETTING A "KEYLESS START PROBLEM" ERROR ON MY DASH BUT MY CAR IS WORKING FINE. I HAVE ALREADY REPLACED FOB BATTERIES AND RESET SYSTEM BY DISCONNECTING BATTERY. FROM MY RESEARCH ONLINE, THIS HAS BEEN A BIG ISSUE FOR HONDA PILOTS.

OUR 3 YEAR OLD CAR AT ABOUT 28,000 MILES STARTED DISPLAYING THE WARNING MESSAGE "KEYLESS START SYSTEM PROBLEM" NEARLY ALMOST EVERY TIME IT IS STARTED. (NOTE, THIS PROBLEM DEVELOPED THE MONTH AFTER IT'S WARRANTY EXPIRED...) WHEN THE MESSAGE FIRST DISPLAYED WE TOOK IT TO THE DEALER, THEY COULD NOT FIND ANY PROBLEM WITH THE STARTING SYSTEM, ONLY THAT OUR ELECTRONICS SYSTEM NEEDED AN UPDATE. WITH THE UPDATE, THE MESSAGE DISAPPEARED FOR A FEW WEEKS, BUT HAS NOW RETURNED AND IS APPEARING NEARLY EVERY TIME WE START THE CAR. THIS HAPPENS REGARDLESS OF WHETHER MINE OR MY WIFE'S KEY IS USED, AND CHANGING THE BATTERY IN THE KEYS HAS NOT CHANGED ANYTHING EITHER. WE HAVE NEVER HAD AN ACTUAL ISSUE WITH STARTING THE CAR, IT'S JUST THAT WE NOW HAVE TO LIVE WITH THIS CONSTANT WARNING LIGHT. IN LOOKING ONLINE, THERE ARE MULTIPLE FORUMS DEDICATED TO THIS EXACT ISSUE FOR 2016 HONDA PILOT'S AND IT SOUNDS LIKE IT IS FAIRLY WELL ESTABLISHED ISSUE FOR THIS MAKE / MODEL.

I WAS DRIVING IN STOP AND GO TRAFFIC ON A FREEWAY, MY FOOT WAS ON THE BRAKE AND CAR WAS IN DRIVE, WHEN I TOOK MY FOOT OFF BREAK AND PUSHED GAS PEDAL THE CAR WOULD NOT GO. I TRIED TO PUT IT IN PARK AND IT WOULD NOT GO, I TRIED TO TURN OFF CAR AND IT WOULDN'T TURN OFF. THE MESSAGE ON THE DASHBOARD SAID TO PUSH BRAKE AND TURN ON CAR (SAME MESSAGE AS WHEN I REMOTE START CAR) AFTER 2 SOLID MINUTES, THE CAR FINALLY DROVE. THE PROBLEM SEEMS TO BE IMPACTED BY THE ECON MODE WHICH SHUTS OFF ENGINE WHEN BRAKE PEDAL IS FULLY ENGAGED. YOU ARE ABLE TO TURN THIS MODE OFF ON THE GEAR SHIFT BUT HAVE TO DO IT EVERY TIME YOU START THE CAR.

I'VE BEEN HAVING ISSUES WITH MY CAR STALLING WHEN I TRY TO DRIVE AFTER BEING STOPPED AT A RED LIGHT. IT DOESN'T HAPPEN EVERY TIME BUT AT RANDOM TIMES. I HAD THIS ISSUE BACK IN FEBRUARY 2018 AND TOOK IT TO MY LOCAL HONDA DEALER IN JACKSONVILLE AND THEY HADN'T SEEN THE ISSUE BEFORE. THEY REPORTED IT TO AMERICAN HONDA, TOOK A FEW DAYS AND THEN REPLACED THE STARTER AND SAID IT WAS A FAILED STARTER ISSUE. IT WAS WORKING FINE UNTIL AUGUST 2018 WHEN IT STALLED AGAIN. IT INSTRUCTED ME TO PUT THE CAR IN PARK AND THEN START THE ENGINE AGAIN. I TOOK IT TO THE LOCAL DEALER AN HOUR AFTER IT HAPPENED BUT THEY WANTED ME TO LEAVE MY CAR SO THEY COULD REPORT IT AND I'M A STAY AT HOME MOM AND NEED TO HAVE MY VEHICLE SO I TOLD HIM I'D TRY TO BRING IT BACK ANOTHER DAY BUT INSTEAD DECIDED TO REPORT THE PROBLEM DIRECTLY TO HONDA TO SEE IF THERE IS ANY UPDATE OR CORRECTION AT THIS TIME. HONDA DIRECTED ME TO REPORT IT TO A DEALER SO I'VE SINCE REPORTED THIS ISSUE TO ANOTHER DEALER IN ST. AUGUSTINE, FLORIDA WHO IS AWARE OF MY VEHICLE HAVING THIS ISSUE. TO DATE, IT HAS NOT OCCURRED AGAIN BUT I ANTICIPATE THAT THIS WILL BE A RECURRING PROBLEM WITH THE CAR IF IT WASN'T A STARTER ISSUE. THE ISSUE SEEMS TO OCCUR WHEN I'M IN STOP AND GO TRAFFIC AND I PRESS DOWN ON THE BRAKE PEDAL AND GO TO RELEASE IT TO DRIVE THE CAR WHEN THE ENGINE IS GOING INTO THE AUTO-IDLE FUNCTION - ALMOST AS IF IT HESITATES TO START BACK UP BECAUSE IT WAS TOO QUICK OF A RESPONSE FOR THE AUTO-IDLE FUNCTION TO TAKE.

MY VEHICLE WAS IN MOTION ON A NEIGHBORHOOD STREET WHEN SEVERAL ALERTS WENT OFF ON MY DASHBOARD: ROAD DEPARTURE MITIGATION SYSTEM PROBLEM, TRAILER STABILITY ASSIST PROBLEM, HILL START ASSIST PROBLEM, VEHICLE STABILITY ASSIST PROBLEM, EMISSIONS SYSTEM PROBLEM, POWER STEERING SYSTEM PROBLEM. I COULD FIND NO REASON FOR THESE ALERTS. I TOOK MY CAR INTO A DEALERSHIP THE NEXT DAY AND WAS TOLD THERE WAS NO ISSUE AND THE LIGHTS WERE TURNED OFF. 10 DAYS LATER THEY ALL CAME ON AGAIN AS I WAS DRIVING ON A LOCAL STREET. THE NEXT DAY WHEN I WENT TO TAKE MY CAR TO THE DEALER, THE LIGHTS HAD TURNED OFF. I TOOK IT IN ANYWAY, AND THEY AGAIN SAID THERE WAS NO ISSUE. I REPORTED THE ISSUE TO HONDA CORPORATION AND WAS TOLD BY ONE AGENT THAT THIS WASN'T THE FIRST TIME THE ISSUE HAD COME UP IN A NEWER MODEL PILOT. AGAIN 2 DAYS AGO, ALL THE LIGHTS CAME ON AND NOW ALSO THE BRAKE ASSIST ALERT IS ALSO ON. I WILL TAKE IT TO THE DEALERSHIP AGAIN. I AM CONCERNED ALL THE FALSE ALARMS MAY BE HIDING AN UNDERLYING ISSUE THAT COULD RESULT IN A DANGEROUS ACCIDENT. I ALSO FEEL THAT HONDA GLOBAL IS NOT TAKING ME SERIOUSLY AS I AM ACTIVE DUTY STATIONED OVERSEAS AND HAVE TO RELY ON LOCAL HONDA DEALERSHIPS THAT DO NOT HAVE MUCH EXPERIENCE WITH THE HONDA PILOT. THE DATES OF THE LIGHTS WERE 17 SEPT, 27 SEPT, AND 6 OCT 2018.

[2016 HONDA PILOT EXL AWD WITH SENSING, 28 K MILES AND 2.4 YEARS SINCE PURCHASE] ON FRIDAY AUG/24/2018 WHILE DRIVING HOME (AROUND 40MPH) THE VSA LIGHT CAME ON AND STAYED ON FOR BARELY 4-5 SECONDS AND THEN TURNED OFF. DID NOT NOTICE ANY MAJOR ISSUES THEN. ON SUNDAY 26/AUG/2018 WHILE DRIVING AT AROUND 30-35 MPH, THE CAR SUDDENLY LOST POWER AND CAME TO A COMPLETE STOP ALMOST LIKE THE BRAKES HAD BEEN APPLIED (DID NOT NOTICE THE ORANGE BRAKE SIGN OR THE COLLISION WARNING BEEP SOUND). I WAS ON THE RIGHT LANE WITH NO ONE BEHIND OR AHEAD OF ME AND NO OBSTACLES IN FRONT. TURNED ON THE HAZARD LIGHT AND THEN NOTICED THAT THE VSA LIGHT WAS ON. CAR WOULD NOT MOVE AND JUST KEPT REVVING WHEN I TRIED TO ACCELERATE. PUT THE CAR IN PARK AND THEN IN DRIVE, NO CHANGE. PUSHED THE VSA BUTTON TO TURN OFF VSA AND BOTH THE VSA LIGHT AND THE VSA OFF LIGHT STAYED ON BUT THE CAR WOULD STILL NOT MOVE. SHUT DOWN THE CAR AND RESTARTED IT AFTER WHICH THE LIGHTS WENT OFF, AND THE CAR STARTED MOVING (ALTHOUGH SLOWLY). DROVE HOME WITH VSA TURNED OFF AND AT A SPEED OF AROUND 20-30 MPH. THE ABRUPT BRAKING/STOPPING WAS PARTICULARLY DANGEROUS AND WOULD HAVE CAUSED A COLLISION EVEN IN REGULAR TRAFFIC ON ANY OTHER DAY. NOTE: THE KEY FOB WAS LOW ON BATTERY AND THE ONLY OTHER WARNING I HAD ON THE CONSOLE WAS ONE INFORMING ABOUT THE KEY FOB BATTERY BEING LOW.

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.
