2021 Honda Ridgeline problems

“With no warning engine started making a loud ticking noise and within a couple of days it was a loud knocking noise. Flashing check engine light came on and engine lost power. Shut down and restarted engine, knocking noise still there but check engine light is not flashing. Knocking noise is loud and vehicle cannot be driven. Mileage is around 170000 but has had regular oil changes. Mechanic has confirmed the engine knock and said not to drive it. Can't afford to replace the engine.”

“The auto idle function- the car engine doesn't restart. This has happened in a busy intersection and won't restart until you have made several attempts to restart. I have brought this to the attention of Honda certified techs.”

“The complete Advanced Driver Assistance Systems (ADAS) has been disabled on my truck and all the warning lights are on. All the safety features ment to keep me safe on the road are no longer working.”

“The contact owns a 2021 Honda Ridgeline. The contact stated that there was moisture inside driver's side headlight housing. The contact took the headlight assembly apart and blew out the moisture. There were no warning lights illuminated. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was contacted and confirmed that the VIN was not under recall. The failure mileage was approximately 43,928.”

“Truck was waiting at a stop light in drive mode and foot on brake pedal. When the light changed to green. I tried to accelerate to go and the whole vehicle shook/lunges forward and shut off. Vehicle went into neutral and wouldn't allow me to go into drive mode. I had to restart the vehicle twice before it allowed me to go into drive again. Vehicle was stuck in the middle of the street with oncoming/ongoing traffic. I had this vehicle at the honda dealer(with documents) three times previous for this issue and its still not resolved. Please help.”

“While making a right turn from a yield sign into oncoming traffic and doing about 15 mph, I depressed the accelerator to speed up and the truck stalled for about 2 seconds. The RPM's drop and you literally lunge forward until power resumes. No warning lights come on and no codes are given. This put my safety at risk and the driver accelerating towards me at risk. This is the first time it happened with my 2021 Ridgeline. However, my 2019 Ridgeline had this happen about a dozen times. Honda Service could never replicate the issue with the 2019 Ridgeline, but there was enough data out there about defective High Pressure Fuel Pumps that they agreed to replace the pump. After replacing the pump, the issue went away. Now my 2021 Ridgeline is doing the exact same thing. I can therefore only assume it's the High Pressure Fuel Pump again. I see that Honda recalled 628,000 vehicles in 2021 and then recalled an additional 720,000 vehicles in 2024 for the High Pressure Fuel Pump failing. My current VIN for some reason is not in this recall. Honda Corporate was of no help whatsoever when contacting them. They told me my truck is not under recall. This is a severe Safety…”
