NHTSA Complaint #11468181 — 2021 HONDA RIDGELINE

I will be filing a issue with our 21 Honda Pilot too as the same problem has occurred in both vehicles with the same engine and transmission. This has happened a total of 3 different times. When I drive the Ridgeline for a long time (over 4 hours)on the expressway and then pull off on a ramp and turn left the vehicle will go into safe mode. The engine light will start flashing and you can not drive over 30 mph. The engine runs rough and idles hard. I have contacted Honda and the dealership I purchased it from. Honda has acknowledged this is a problem and has occurred multiples with many different vehicles. The dealership I work with has acknowledged the same thing as they have several vehicles that have been brought in with this problem. I have waited several months for Honda to come up with a solution, so far they have not. This is a safety concern because what would happen if this same situation came up when I'm pulling my trailer or on the expressway at higher speeds. This could cause an accident. This first started on my Ridgeline in November of 2021. It has happened several times since then. Every time there is no code the computer keeps, even though each time the engine light is flashing. What I have been told is the computer thinks the engine has backfired and goes into safe mode, but Honda doesn't know why it does this. If you turn the vehicle off and restart it, the problem goes away. When the dealership has run a diagnosis off the computer, there are no codes the computer throws. Even though the check engine light is flashing when this occurs.
