The engine required a short block replacement at approximately 40,000 miles. There was a severe knocking sound and the dealer diagnosed heavy scoring and abnormal wear present on the front bank cylinder walls. The result was excessive internal engine clearance and cylinder wall damage. Engine cylinder piston block holes were worn beyond spec. After 33 days the vehicle was returned and developed a growling/grinding noise when the AC was in operation and at lower speeds that followed the RPMs. Vehicle was returned to dealer and told sound was normal operation for this model and stated it was coming from AC Compressor. Independent shop verified 2 days later AC compressor was failing and possible metal contamination. AC compressor is backordered with no ETA.

Honda Part #80872-SN7-003 failed at 3years and 40,000 miles which Honda will not cover under warranty. This is a simple O-Ring for the AC line which has a life span of 10-15 years. Apparently this has been common on 2023-2025 Pilots and passports and thus should be a recall issue.

Car has been serviced at same dealership I purchased from. All service up to date, Gas type shell gas brand used 95% of the time. (Noticed November 2025)issue a month after recommended transmission flush and an engine oil change. Rough idling (especially when temp below 60⁰) and almost like a miss fire when driving. No check engine light, and dealership had vehicle for two days but claimed unable to replicate issue suggested these engines are prone to carbon buildup. But recommended I switch to premium gas. SUV drives rough and then randomly reverts to normal smooth driving, also seems to struggle when switching gears, spoke to other owners of same type and a pattern of previous years owners mentioned potential issue with VCM. Major issue: Rattling during start up and driving ( sometimes goes away randomly) Car struggles with gear switching. Engine/transmission hesitation.

All listed problems act sporadically. Dangerously Defected 2023 Honda Pilot. Numerous problems with vehicle over several months. Kept taking it back to Charlie's Honda and was told they could not reproduce the problems I was stating. The Vehicle will bog, hesitate and jerk while driving. Charlie finds nothing wrong. Actually all items that are functioning incorrectly, Charlie's tell me they cannot repair anything when they can not reproduce the problem. They tell me that the 10 gears are so close that they skip? Sorry, that's ridiculous! Finally I called previous Owners, (Which Charlie's Honda refused to give me until I had to show them the Chapter 10 S1475 I had with me.) [XXX] from Herman, ME. Ph # [XXX]. They told me to tell you to please call them because they are very upset. After several times taking the Honda back to Charlie’s with no repairs done they went to get a different vehicle at Charlie's Toyota and the Toyota Manager told them that the Honda Pilot was a very dangerous vehicle and will not be put out on the Lot for resale. The [XXX] stated that they almost crashed while taking a left at an intersection with their children in the vehicle because it almost came to a complete stop. This serious problem is doing it to me now and this is why I’m taking this action. The [XXX] left the Pilot at Charlie's Honda for several days but Charlie's said they could not reproduce the problem. Just a few of numerous defects stated below and reported to Charlie's Honda but received no repairs, just excuses : The Airbag says off when a 175 lb person sitting in the front passenger seat. Rear camera does not register an object. I was told it didn't work because it was 1 inch from rear side camera and it was too narrow. nothing done. Speed said I was doing 85mph. I was doing 40 mph. mechanic said he sees them register 100 mph. nothing done. The tech screen goes black. Cannot shut radio off. After trying 3 times. Much more to report!

Transmission light came on and said: “Emissions system problem. Power may be reduced. See your dealer.” Spoke to dealer who said they are unsure how this could have occurred possibly wear. The vehicle has 41k miles and I’m the only owner. Also said the cam plate is leaking oil which caused the sensors to be damaged and causes the vehicle to lose power while driving

1. What component or system failed or malfunctioned, and is it available for inspection upon request? The emissions system continues to malfunction despite multiple repair attempts, with the emission sensor reactivating as recently as February 2025. The VTC oil control valve also previously leaked but was replaced. The battery and seatbelt buckle issues were successfully resolved. The vehicle and components are available for inspection upon request. 2. How was your safety or the safety of others put at risk? The emissions system malfunction may impair engine performance or emissions control, creating potential environmental and mechanical hazards. While the seatbelt and battery issues have since been resolved, they previously created safety risks—such as an unreliable restraint system warning and unexpected failure to start the vehicle. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, the dealership (Winter Haven Honda) has confirmed the emissions system fault multiple times, including diagnostic sessions in December 2024, January 2025, and February 2025. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? The vehicle has been repeatedly inspected by the dealership in consultation with American Honda Motor Co. No inspections by police or insurance representatives have been reported. 5. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Yes. The emissions warning light first appeared on December 9, 2024, and continued to reappear on December 12, 2024, January 7, 2025, and again in February 2025. These warning messages clearly indicate an unresolved system issue

Vehicle stopped with no warning while waiting in traffic at a red light and it took a while to restart. Same thing happened while parked in a lot waiting. The former issue was dangerous as I was in traffic with numerous vehicles moving around me with my family in the car as I got out to check the problem under the hood. The latter issue happened while out of town which is scary and dangerous considering it was a remote area.

Car wouldn't go more than 25-30 miles/hour and rpm was at 5-6, had to use blinkers on highway. Luckily there weren't any injuries, i was scared of the situation as I was travelling with my toddler and newborn. After reaching home, car wouldn't reverse. I had shutdown and started the car multiple times before i could reverse. There was smell as if something was burning in the engine. I shutdown the car for 15-20 mins for smell to go away and restarted the car again, that is when check engine light was turned on with warnings about transmission, AWD and emission systems. What component or system failed or malfunctioned, and is it available for inspection upon request? Transmission failure, AWD system failure, Emission system failure. Has the problem been reproduced or confirmed by a dealer or independent service center? Confirmed by dealer, full diagnostics not available. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No warnings before the failure. Dealer was saying about repairing the transmission, and also mentioned the car value will be depreciated significantly. I traded in the car for new pilot, as transmission problem are recurring and also losing significant value on the car. My loan and monthly payments went up because of something i didn't do. I am being punished for the someone else mistake. Dealer wouldn't provide any incentives too.
