2021 Honda Passport: engine stalls while driving

Filed Sep 18, 2026 · Engine · CA

The vehicle experienced a sudden internal mechanical failure while driving, resulting in loss of propulsion and complete engine failure. The vehicle was towed to an authorized franchised dealership service center (Gardena Honda) for inspection. No check engine lights, warning lights or any pile pressure warning! Oil change was 2,500 miles until next service. Upon complete teardown and diagnostic inspection, factory-certified technicians confirmed internal engine damage, specifically connecting rod bearing failure leading to a seized engine requiring a complete engine replacement ($9,375.00 total repair cost). This internal failure presents a severe safety hazard: an unexpected engine stall or lockup at highway speeds risks loss of power steering, loss of power brakes, and an immediate crash. Symptoms align directly with the federal safety agency Recall 23V‑751 and ongoing federal investigations regarding Honda 3.5L V6 engine connecting rod bearing failures, where out-of-spec manufacturing leads to premature bearing wear and sudden engine seizure. The vehicle is maintained according to manufacturer specifications and has 55,649 miles. The failed components remain preserved at the dealership service department for federal or manufacturer inspection upon request.

There is a known issue with auto idle feature. If you do not manually turn off every time it stays on and occasionally will cause car issue when stopping. I have had it happen in vehicle about a dozen times. When you fully depress brake engine is suppose to i gel to save gas however on occasion the vehicle will completely stall out. I have had this issue happen when approaching stop signs or in traffic situations. The biggest problem is trying to reengage car. Sometimes you can feel it starting to do this and if you quickly apply gas you can avoid it however sometimes the car will lock up with display lights and you have to keep pushing the Engine stop button to turn off the vehicle and turn vehicle back on. It is sometimes difficult to even turn off engine vehicle when this happens but seems to be only way to get vehicle to respond. I have had vehicles behind me almost hit me while I try to get vehicle out of this mode. I know it’s an issue as it’s all over the forums when you search for fix.

To preface: All of these issues only occur when the engine idle feature is on. I have not experienced any of these problems when the feature is off. Question #1: When I release the brake with the engine idle on, the vehicle will sometimes completely shut off. When this happens, the steering wheel and brakes lock up, and I am unable to restart the vehicle for at least 60 seconds. Question #2: On one occasion, my wife, our 8-month-old child, and I were stuck at a green light for about 60 seconds while unable to restart the vehicle. Cars were passing by at over 50 mph, and we were relying on other drivers to notice us in time. This situation has happened multiple times and poses a serious safety risk to both us and others on the road. Question #3: I have not taken the vehicle in for service because the issue is difficult to reproduce consistently. That uncertainty is part of the problem, along with the anxiety of not knowing whether the car will suddenly shut off. Question #4: For the same reason, I have not been able to demonstrate the problem on demand. However, the main concern is that I should not have to worry about my vehicle stalling when I go to accelerate. Question #5: The vehicle has completely shut off four separate times over the past year. On one occasion, after releasing the brake, the engine struggled to reach normal RPMs and the check engine light came on. I pulled over, turned the vehicle off, restarted it, and it seemed fine afterward, although it had noticeably less power while the check engine light was on. Lastly, there have been several instances where the engine did not completely shut off when the idle feature was on, but when I released the brake to accelerate, I heard a clicking sound and the vehicle seemed as though it was about to stall. It then resumed operation normally as the idle system re-engaged. Since this happens intermittently, it has been difficult to recreate during a diagnostic inspection.

My Passport has shut down 4 times recently while idling at a stop. There is a auto start/stop feature on the car that shuts down the engine at stops until the brake is released. The problem is that it sometimes does not restart after releasing the brake. The first 3 times it happened at an intersection so it was no big deal. The last time, today, it stalled on a highway as soon as I stopped for heavy traffic. The car was automatically put it neutral and it took me about 40-50 seconds to realize what happened and to restart while the lanes next to me started moving at highway speeds. I looked up the problem online and saw a "Honda Idle-Stop Class Action Suit ([XXX])" and found out that it is happening to others as well. [XXX] I am not looking for money but want this to be looked at. I will be taking my vehicle in for repairs at a Honda dealership later this week.

my vehicle shut off during idle for energy compensation. It failed to restart and allow the vehicle to be in drive causing the car to stall out and not turn back on.
