2020 Honda Passport engine problems

Filed Oct 16, 2026 · Electrical, Engine · TX

My 2020 Honda Passport (approximately 52,000 miles) has experienced recurring Auto Idle Stop/engine restart failures in May 2023, November 2024, and October 2026, despite multiple repairs by an authorized Honda dealership. The latest incident occurred in October 2026, immediately after a routine state inspection. While stopped with my foot on the brake, the dashboard unexpectedly displayed "N" (Neutral) and instructed me to remove my foot from the accelerator, although I was not accelerating. The electronic gear selector would not respond, requiring me to turn off the vehicle. Shortly afterward, while stopped at a traffic light, the brake pedal became extremely stiff, and the engine would not restart. The dashboard, radio, and other accessories remained operational. The battery warning light appeared only during restart attempts. I eventually restarted the vehicle and returned home. These failures pose a serious safety risk, potentially leaving the vehicle immobilized in active traffic and compromising normal brake assistance. In May 2023, Honda performed a PGM-FI software update under Service Bulletin 23-008. When the problem returned in November 2024, Honda replaced the starter assembly and starter relays and performed an engine valve adjustment under Service Bulletin 23-009. Despite these repairs, similar symptoms returned in October 2026. Another driver had also noticed hesitation and unusual cranking sounds during automatic restarts approximately one month earlier. I contacted American Honda, reported the recurring failure, and requested a manufacturer-level technical inspection. Although my case was escalated, I have received no substantive follow-up despite multiple calls and written inquiries. The vehicle has remained parked without a confirmed manufacturer inspection or repair plan. The vehicle remains available for inspection. I am concerned that Honda's prescribed repairs have not resolved this recurring safety-related malfunction.

I have a 2020 Honda passport elite with a 3.5L V6 J35Y6 with 108k miles on it which is similar to the engines that have been recalled in other models like the pilot, ridgeline, and odyssey, and I have researched multiple vehicles with a similar problem of spun rod bearings which has left metal debris in my engine. I have found hundreds of passports that have been reported with the same issue. My vehicle is currently sitting at the dealership and they said it needs a new engine due to this issue. My vehicle is not drivable until the engine is replaced. The dealership estimated a cost of over $5k.

In April 2024 on a road trip to [XXX], the engine suffered a catastrophic failure without warning near [XXX]. The connecting rod or rods broke, and one of them exited the engine. State Police and Local Fire Department responded because a passer-by saw smoke from the expired engine and reported a fire - there was no fire, but the engine oil was leaking down onto the exhaust pipes, causing smoke. The local Honda dealership in Bloomington, IL and Honda itself were not very cooperative, claiming the engine was not maintained properly. I submitted our mechanic's records as proof twice to Honda, yet they still resisted. Finally I contacted the original Honda of Naperville dealership where we bought the vehicle, and that got Honda to partially refund the money (under extended warranty) that we spent to repair the motor. In the end, the motor was replaced with a used 25,000 mile unit, which was the only option under the warranty. That did not sit well with us, so we capitulated, accepted the used engine, then sold the Passport back to the Bloomington Honda. Overall, we had to pay for towing 35 miles, the expense of renting a vehicle for about 1 week, and other extra costs plus the time and hassle associated with multiple phone calls to Honda. The total expenses incurred was $1,738 for towing and a rental vehicle to complete the trip. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Engine failed and now the piston rod is knocking inside the engine. Engine failure while operating a vehicle is extremely dangerous and could cause an accident or death to myself and anyone else around my vehicle while its being operated. This type of issue can even cause a fire in the engine bay. When the issue presented itself I was going 60 down the highway. Yes, the vehicle has been in two independent shops which have both confirmed the engine failure due to premature connecting rod bearing wear which was most likely caused by manufacturer crankshaft issues. No it has not been inspected by manufacturer, police, insurance, or others. No there were not any warning lights, messages, or sysmptoms prior to the failure.

Car shuts down and does not restart. Also goes to neutral and does not allow car to be steered. Also seems to be related to auto restart.

At approx. 5 years of age & 67,500 miles, the engine began to make rattling or ticking noises that were in sync with engine speed (RPM). Within 1 day of noting the noise, I took the first available appointment to bring the vehicle to my local Honda dealership, Napleton Honda in Loves Park, IL. Napleton Honda diagnosed the issue as "rod knock" due to failing connecting rod bearings. The dealership advised that the only recourse is to replace the engine. Honda Motor Corp (manufacturer) was notified by me about the issue, but they declined to make any substantive effort to assist with the repair costs despite the fact that the issue is increasingly known and documented as per the federal safety agency campaign # RQ24013

The first major issue I just started running into at about 90,000 miles is the engine auto start stop feature. I usually disable it when I drive due to the inability for the car to provide adequate start from a stop, but when I don’t, I’ve had the vehicle completely stall on me at a stoplight and won’t let me restart the vehicle for several minutes leaving me stranded and vulnerable sitting in a lane on a highway. I’ve had about a dozen instances of this issue now over the last several months. The second issue is with the adaptive, cruise control or the emergency, stopping on the vehicle where it will jam on the brakes, even though there are no cars in front of me it inaccurately picks up vehicles in the oncoming lane. There are more than 8 feet separated from my vehicle. I have had the system recalibrated and have complained about it at the dealer, but I’ve been told that there’s nothing wrong with it. Just thought I’d report that as well because it’s almost got me into several accidents by jamming on my brakes for no reason and almost being rear-ended.
