After driving on the freeway for about 1 hour, took the exit to the right. Check engine light came on and vehicle had loss of power and was shuttering. Attempts at accelerating were met with little to no power. Tried turning off eco mode, no change. Limped to the first safe place to stop, avoiding any fast traffic behind. Shut off vehicle, and when I started again, no check engine light, vehicle operated as normal. I fear to think what would have happened when if my child were driving and had to make a merge onto heavy traffic. This is a serious safety issue that I have learned is known. A fix needs to happen before someone is seriously hurt.

Upon exiting or entering the highway, the truck loses power and will not accelerate. This happens after multiple hours of highway driving and seems to only happen when the temperature is near or below freezing. The Check Engine Light (CEL) comes on and is flashing. This has happened to me four times. Three of which were exiting one highway to merge onto another and there was ample room to slow down and pull over. One time was merging onto a highway from a Rest Stop with a great deal of traffic and I was fortunate the shoulder was available to avoid being collided with. The first time was on 11/6/2021 (2200miles), second and third was on 12/19/2021 (5600miles) and last time was 3/9/2022 (10100miles). All occurrences the gas tank had ample gas. Shutting the truck off and turning it back on clears the CEL and no error codes are stored (according to the dealer). This problem has been reported multiple times and yet there has been no response from Honda. Also, even though the error codes are not present after the vehicle is turned off and back on, I was able to capture three error codes prior to turning the vehicle off P0302, P0303, P0300.

Vehicle went into "limp mode" after exiting a freeway. When attempting to merge into roadway, vehicle flashed CEL for engine. Vehicle shut down 3 cylinders giving very little power to merge into traffic. Unable to get vehicle over 30 mph on a busy road. Honda dealer said no codes were stored and haven't heard of the complaint previously. Vehicle had no issues previously. 6,000 miles on a new vehicle.

This is an unsafe vehicle to drive and can cause injury or DEATH. I along with many others have been having problems with the CEL flashing and engine running properly. The dealers can't find a cause because the code deletes itself and the problem temporary goes away when you shut the engine off and is NOT saved in the computer. It has been a complete waste of time going to the dealer only to find no codes stored. I am not alone in this, as many others are starting to have this exact same problem during the exact same driving conditions. See the forum below: https://www.ridgelineownersclub.com/threads/2021-check-engine-light-flashing.229929/#post-3220773 Here is the first time it happened. (THIS HAS HAPPENED 3 TIMES ALREADY) (DEC 7, 2021) Hello all, I have a 2021 RTL-E. After driving on highway for an hour and a half at 80mph, I exited the highway and as soon as I pulled onto a secondary road the check engine light started flashing and the engine was hesitating with little to no power and poor shifting. I limped it to safe place to pull over (aprox 3 miles) and shut the truck off. I checked under the hood and didn't see anything and after approximately two minutes I restarted the truck and the light was gone and it drove fine after that. (It was 15?F with 10,250 miles at the time and not towing or hauling anything) I drove it the next day 4 hours on Highway without any issues. Has anybody else experienced this issue on the 2021's? There's not enough room to type the other times this problem occurred!!! This is an unsafe vehicle to drive and can cause injury or DEATH. The 2021 Honda Ridgeline is no longer the dependable vehicle that I was hoping to have when I purchased it NEW in June of 2021. I live in a rural area and do not have a dealer that is close by which is why I bought a Honda in the first place because it was Supposed to be a dependable vehicle. This needs to get resolved and I would appreciate any help on how to resolve this.
