Since purchasing this vehicle new, the Auto Idle Stop (AIS) system on my 2017 Honda Pilot has intermittently failed during the engine restart sequence after the vehicle comes to a complete stop. When the AIS system shuts the engine off and I release the brake to resume driving, the vehicle intermittently fails to restart properly or does not restart at all, preventing the vehicle from moving as expected. In some instances, warning messages, including a collision mitigation message, has appeared on the dashboard before the car restarts. This condition has occurred repeatedly over several years and has happened at intersections, while stopped in traffic, and while stopped on highways. The inability of the vehicle to restart and move creates a safety risk because the vehicle may remain disabled in active traffic when acceleration is needed. The issue was reported to the selling and servicing Honda dealership (Cambridge, Honda in Cambridge MA) multiple times over several years. In August 2025, the vehicle received Honda's prescribed repair under Service Bulletins 23-008 and 23-009, including replacement of the starter assembly, starter relay, and battery. Despite these repairs, the same condition returned less than one year later and has occurred at least seven additional times. The vehicle stalls and sometimes displays the collision mitigation/crash warning message before restarting. In June 2026, the vehicle was inspected again by the dealership. Technicians were unable to reproduce the condition during testing and declined to perform additional repairs. The defect remains unresolved. The vehicle has already received Honda's recommended AIS repair, yet the same stalling and crash mitigation message continues to occur. The intermittent nature of the defect makes it difficult to reproduce during short dealership evaluations, but it continues to occur during normal operation and presents an ongoing safety concern.

All of a sudden, the car began to make a ticking noise (it sounded like a playing card was in the spoke of a bicycle). I brought the car home and took it to the Honda dealership in Poway, CA. They diagnosed the car with pitting in the rod bearings in cylinder 4. They told us that this can cause engine failure (do not drive the car) and that the engine needed to be replaced. There were no error messages or warning lights. This could have been extremely dangerous for those around us had the engine failed while my daughter and I were driving, or if the car had stopped suddenly. The three options given were to replace the engine with one with 20,000+ more miles than the original engine, replace the short block and associated gaskets with a new one, or $2500 (as-is) for the car. We replaced the short block and associated gaskets at a cost of approximately $ 8,500. As my husband was doing his research, he found that there had been a recall for the 2016 and 2018-2020 Honda Pilots for the same issue. Please be aware that this has happened to our car too, and it is very dangerous and expensive to repair. Honda should be held responsible for ensuring that all Pilot engines are safe and that the defective rods are replaced free of charge to owners under a recall.

There is a loud metallic knocking sound coming from my engine. I have lack of acceleration power, and the check engine light came on. You are more than welcome to come inspect the car. My safety was placed at risk as my engine can blow up, and/or I lose acceleration while driving and cause an accident. The sound is continuous and will be until the Rod Bearing is fixed so it’s easily reproducible. Yes it’s been looked at by a mechanic.

The car began making a knocking noise when it was turned on and began moving. The noise continued every time the car was started until the engine light turned on and began blinking. We pulled the car over immediately. After turning the engine off and letting the car rest, we tried starting the car again and the light was off. Roughly 20 minutes later, the engine light began to blink again, followed by all the lights on the dashboard blinking. We had the car towed to a local Honda dealer. After being inspected, the dealer said the car needed new fuel injectors and an "Engine rebuild/replace: the engine rod knocking during start up and shutdown, drained oil sample and found excessive mental particles suspended in oil."

While driving on the highway at approx 60mph my car completely lost power. I had no warning lights on the dashboard and the only warning I got was an alarm sound right as all the power to the vehicle cut off. I had to use my e-brake to help me stop and coast to the brake down lane. I couldn't get my car completely off the highway lane and had no way of getting out of the vehicle. I was towed off the highway and contacted my dealership. Prior to this the car was idling a little rough in the morning.

The connecting rod bearing went out in the engine of our 2017 Honda Pilot. The car stalled and then died. It cost us $10,000 to fix it and it only had around 130,000 miles on it. Our Honda dealer told us to hold onto our receipt because this is happening a lot with Honda Pilots and there will eventually be a recall on this. This was so unsafe and we were fortunate that our teen son was only going 5-10 miles on a gravel road when this happened.

Driving to work on the highway and the Honda pilot suddenly slowed and stopped accelerating, started riding rough and making a loud whistling blowing noise. Check engine light was suddenly flashing. I was able to pull over into a lane split zone before being hit by all the traffic going around and bumping horns at me. I was terrified but thankful to be alive. I want in a good spot though, cars and big trucks were still speeding by pretty close to me. I started inside and called AAA. I tried turning on the car but it just made a fast tapping noise. AAA worked to safely get me out and tow the car to the mechanic my wife and I chose. The mechanic ran a diagnostic report that says p0306 misfire in cylinder 6, and tear in inlet air boot. They said there is an engine problem that they don't service. We towed it to the Honda dealership. Late the next day the mechanic at Honda says we have an engine problem that is not due to the codes on the diagnostic report and is not covered under warranty and costs $7000 for labor and with a rebuilt engine, about 11k to $15k total. He says the engine was seized. He said it initially had no power, then they jumped and put a battery and the engine just made a thud sound. He said he could not generate another diagnostic report because he couldn't get the engine to turn on. We told him we saw that the engine problem was a known issue and that Honda was extending warrantees to 150k and 10yr and could he see if we were haven't that same problem. He said that problem was minor and only covered a few new parts, not the whole engine. I asked why was pep boys able to get a diagnostic and he could not. He said he doesn't know why the engine seized between pep boys and being checked at Honda. He said maybe the previous mechanic did something wrong. Now we have no car and have already purchased a 3rd Honda not even knowing we were driving around a death trap. The Honda dealership that sold us the accord didn't even warn us. We could have died.

On Thursday May 7th, while driving the 2017 Honda Pilot Elite it lost power and all the dash lights started to come on. Once we limped it to our home, and the code information was obtained, it revealed number 3-cylinder misfire. After replacing all the spark plugs, I started the car to make sure all the codes were cleared and heard a "knocking noise". After further investigation noted the following, I found the following information via a Google search, is there a recall for 2017 Honda Pilot knocking noise. Found that NHTSA is doing a major investigation on the 2017 Honda Pilot for a connecting rod and knocking noise. Honda did a recall in 2023 for the year model 2016, 2018-2019. This is the same engine that was in the recall for doing the same thing. NHTSA is currently investigating a potential recall of 1.4 million Honda and Acura vehicles, including 2017 Honda Pilots, over engine failures linked to connecting rod bearing defects that can cause knocking, stalling, or complete engine failure. credit Autoblog+2.

Subject: Engine Knocking Noise – 2017 Honda Pilot Hello, I’m reaching out because my 2017 Honda Pilot has recently developed a noticeable knocking noise coming from the engine area, especially during acceleration and low‑speed driving. I’m aware that some 2016 Honda Pilot models have experienced sudden engine seizure, stalling, or failure with little warning. I also learned that the 2016–2020 Acura MDX, which uses the same engine, was issued an engine‑related recall. This makes me particularly concerned that the noise may be an early sign of a serious issue. I’d appreciate having the vehicle evaluated as soon as possible. Please let me know your earliest available appointment and whether it’s safe to continue driving in the meantime. Thank you, Honda Pilot owner

Over the past couple of months the the vehicle has been "throwing" misfiring cylinder errors, particularly cylinder 4 (P0304) and every once in a while cylinder 1 (P0301), and a catalytic converter bank 2 error (P0430). Last week, I filled up with premium fuel and added a catalytic cleaner. This eliminated the P0430 error and reduced the frequency of the P0304 error. Yesterday ([XXX]) we were driving from Casper, WY to Gillette, WY for a volleyball tournament. About 35 miles into the trip, we were travelling at a speed of 72 mph when the tires squealed, accompanied by metal clanging and extreme vibration in the engine; the car nearly came to a complete stop. I was able to maintain control of the vehicle and pull off to the side of the road. I looked down at the console display and noticed that the check engine light was blinking. I connected an OBDII scanner and observed a P0304 error. I then tried to pull forward slowly and the car barely moved and the engine clanging and vibration persisted. At that point I turned off the engine and called a tow truck; I also called my son to pick up my daughter and take her to her volleyball tournament. While waiting for the two truck, I attempted to start the car so I could run the OBDII scanner again. The car would not start.
