PURCHASED A 2016 PILOT EX-L CERTIFIED USED WITH 8K. WHILE PRESSING THE BRAKES, THEY WOULD GO PRETTY FAR DOWN BEFORE ENGAGING. IF I LET UP ON THE PEDAL AND PRESS AGAIN, THEY IMMEDIATELY GRAB LIKE THEY ARE SUPPOSED. I HAVE TAKEN THE VEHICLE IN SEVERAL TIMES, BRAKES BLED AND FLUSHED, STILL THE SAME. I WAS INFORMED THAT HONDA SAYS THE DISTANCE OF BRAKE PEDAL PRESSING DOWN IS 2" IS NORMAL. I ALSO HAD ISSUES WITH THE SCREEN GOING OUT, AND THE DRIVER SIDE VENT WOULDN'T STAY UP, AND THE A/C WASN'T COOLING PROPERTY. ALSO THE SYSTEM WONT CONNECT TO MY PHONE RANDOMLY. I NOW HAD A PROBLEM WITH THE TRANSMISSION. MAKES A RATTLING NOISE WHILE DRIVING/COASTING AT ANY SPEED. HAVE TAKEN IT IN AND WAS TOLD IT WAS THE BUMPER AND HOOD NOISE. AFTER PAYING FOR THAT, I STILL HAVE THE NOISE. THE RPMS JUMPS FROM UNDER 2 TO JUST ABOVE TWO, THEN DOWN AGAIN. WHEN THE RPMS DO THIS THE NOISE HAPPENS AND ALSO THE ECONO MODE TURNS OFF TO WHITE, THEN GREEN AGAIN. NOW IT FEELS LIKE WHEN THIS HAPPENS THE TRANSMISSION FEELS AS IFF IT IS TRYING TO GO INTO GEAR, SLIPPING. NOW WHEN DRIVING AND TRYING TO PASS, IT SEEMS TO SLIP. IT IS DEFINITELY A SAFETY ISSUE! COME ON HONDA PLEASE FIX THE ISSUES.

KEYLESS START SYSTEM PROBLEM ERROR. THIS ERROR MESSAGE POPS UP ON THE SCREEN FOR WEEKS AT A TIME AND THE DISAPPEARS FOR AWHILE ONLY TO REAPPEAR. SO FAR I HAVEN'T HAD A PROBLEM ACTUALLY STARTING THE VEHICLE. THE PROBLEM IS THE SWITCH ASSEMBLY, ENGINE START & STOP - HONDA (35881-TG7-A03). THERE ARE HUNDREDS OF COMPLAINTS ON THE HONDA PILOT PROBLEM FORUMS, YET HONDA DOES NOT RECALL THE VEHICLES TO RESOLVE THE PROBLEM. INSTEAD THE DEALERS CHARGE ~ $150 TO DIAGNOSE THE PROBLEM AND $300-400 TO REPLACE THE UNIT. I WATCHED A VIDEO OF A HANDYMAN REPLACE THE UNIT IN 7 MINUTES AND HE PAID ONLY $70 FOR THE PART. THIS IS CRIMINAL BEHAVIOR NY HONDA AND ITS DEALERS IN MY OPINION. I WILL JUST FIX IT MYSELF, BUT I SHOULDN'T HAVE TO. YOUTUBE VIDEO OF PROBLEM AND REPAIR.

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.

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 Preliminary Evaluation is being upgraded to an Engineering Analysis, EA25004, to further consider the potential safety defect, including gathering additional data regarding Honda’s service campaign efficacy. ODI is additionally expanding the scope for the Engineering Analysis 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 campaigns.
