This happened on the interstate. This happens repeatedly (about once per week) for my spouse, but today was the first time for me. I was changing lanes at about 75 MPH, and the tachometer dropped to zero despite my further depressing the accelerator. I took my foot off and again depressed the accelerator and the engine reengaged. I have not had the dealer look at this yet. There were no warning lamps or other messages in the driver information.

The incident with my 2022 Honda Ridgeline Black Edition occurred while driving on the interstate from Minneapolis back to my home in Illinois (Chicago suburbs). While taking an exit ramp to a different interstate I slowed down before the turn and then, when accelerating to merge onto the other interstate, my Ridgeline "check engine" light began flashing and the vehicle began to limp along at a maximum speed of ~40MPH. I quickly pulled off to a parking lot and arranged for a tow truck for the next day, as it was very late in the evening and very cold. The next morning, I went to meet the tow truck at the parking lot, and I started up my Honda Ridgeline with no issues (and no check engine light). It was then that I found a message board conversation titled -??Check engine light flashing after freeway driving-?? on the internet [XXX] ) and discovered this issue had been occurring with other Ridgelines in similar conditions - i.e., long drives in cold weather where the driver slows down and then accelerates. In all cases, it seems that simply turning off the vehicle and re-starting a few minutes later fixes the problem, but not before you encounter a potentially dangerous situation with a disabled car on the road. On [XXX] I took my Ridgeline in for service at my local Honda dealership (where I had purchased the vehicle in 2022) and they were unable to find any issues or error codes stored (no error codes being stored seems to be the common occurrence with other drivers who have had this issue). In my view, this issue, while somewhat uncommon due to the particular set of circumstances needed to produce the error, presents a major safety issue for the Honda Ridgeline as it can essentially disable your vehicle while driving on the interstate. I-??m hopeful that the NHTSA can work with Honda to quickly diagnose and resolve this safety issue before it leads to tragic consequences.

After driving approximately 2.5 hours at 70 miles per hour, I took an exit off of the interstate and stopped at the stoplight at the bottom of the exit ramp. After about 1 minute the light turned green and I accelerated sharply and turned left. The Check Engine Light started to flash and the vehicle experienced a significant loss of power. I was unable to accelerate to match the speed of the traffic around me and created a hazard while attempting to find a safe place to pull off the road. After about 1/4 of a mile I was able to pull off the road. I shut off the vehicle and waited about 5 minutes. I restarted the vehicle and the light didn't return and it had full power, so I completed my trip. Additional info, outdoor temp was 34 degrees F. I was driving into a 25 MPH headwind during the 2.5 hours of internet travel. I took the vehicle to the dealer as it is under warranty and has about 18,000 miles. Dealer removed intake manifold, removed water that had collected in the intake manifold and reassembled. Vehicle computer didn't store any codes. Dealer was unable to explain how the water got into the intake manifold or provide any satisfactory reason or logic as to why it would not occur again under the same conditions. My concern is that there is some design flaw inherit to the air intake of this engine that allows condensation to collect under some conditions and causes a misfire that puts it into a limp mode that diminishes performance until the engine is cycled off/on. It is difficult to understate how terrifying the experience is of having traffic wiz around you with horns blaring and not being able to move out of the way.

After driving for approximately 275 miles in winter temperatures but with normal driving conditions, upon taking a banked turn the check engine light flashed while the engine lost power and caused the car to begin shaking. I pulled over and was able to pull diagnostic codes from the vehicle. The vehicle reported that two cylinders were misfiring. Upon restarting the car the vehicle operated normally. I brought this vehicle in to the dealer who was familiar with the problem but responded that Honda has no resolution yet. This problem seems to affect multiple years and models of Honda vehicles (using the 3.5L engine).

On two seperate occasions now my 2022 Ridgeline, which has less than 5000 miles, has lost considerable power when attempting to merge onto a highway and had the check engine light start flashing. This has required me to quickly pull over off the road as I was merging and unable to get my speed up. When this occurred, I had been driving on a highway for about an hour and was merging from the highway onto a larger interstate. The temperature outside was approximately 20 degrees F and my gas tank was above 3/4 tank that was purchased 2 days earlier.

Driving on interstate in 10 degree F weather. Exited interstate on exit ramp. Stopped at end of ramp. Light turned green so I accelerated and the check-engine-light began flashing, engine shook a little bit, and I could no longer drive over 30mph. Multiple people behind me honking, flashing lights, etc to try and make me go faster when I couldn't.

When stopped at a red light and idle engine auto-stop engaged the vehicle displayed battery warning light and a -??Shift to Park-?? message on display. Vehicle had to be shifted into park and restarted manually before it could move. Your Questions: 1. Battery/Auto-stop-start system. Sure, you can inspect it. 2. Vehicle was non-responsive and immobile at a busy intersection. 3. No, the incident just happened today, but apparently the NHTSA is investigating a similar problem in the Pilot, a mechanically identical vehicle. https://wtop.com/national/2022/06/us-investigating-complaints-that-honda-engines-wont-restart/ 4. No 5.None. Red battery dash light illuminated at time of incident. I did not notice it before this happened. The vehicle had been at freeway speeds for 30+ minutes, so low voltage shouldn't have been an issue. It was below-freezing at the time, however.
