The automatic high beam assist does not function properly. The high beams go on and off constantly. They pick up their own reflections even on dark roads with no on coming traffic. They will stay on when other cars are approaching. They come on when in traffic. They flash on and off at cars approaching. I have requested two dealerships to look into this and they did not even put it in the work order to check the issue. I have complained to Honda customer service with no satisfaction. I am afraid the lights will affect on coming cars or aggravate cars in front of me. The system is absolutely useless and should not be offered as a safety option.

This is a general issue that you can find in the forums of the Honda Pilot/Ridgeline/Passport. Is affecting all of them. Very easy to replicate. When using adaptive cruise control and the person in front of you changes lanes. If that person that moved to another lane slows down your vehicle will slow down too, thinking that the car is still in front of you. This is a huge security risk that can cause a rear-end collision if the person behind you is distracted.

On 1/21/22,After driving an hour at 75mph exited onto off street. While driving through traffic truck began to "sputter" and wouldn't accelerate. I then noticed flashing engine light. After driving about 5 minutes through traffic because I had no place to go, I parked and shut it off. Turned back on no light and no issue. Since I needed to drive home later that night I brought to a dealership for diagnostics. Like everyone else in the Honda forum, no codes or errors. 2675 miles on the truck, about 1/2 tank of gas. Temp around 20 deg. On 2/12/22, Drove 160 miles, 70-75mph, temp 10 degrees, gas tank 3/4 full. Didn't stop that entire time. Got off on an exit and continued to drive between 30-45 mph for about 4 miles without coming to a full stop. Finally I reached a stop sign. Cross traffic did not have to stop. After stopping (engine idle was on but don't think engaged) and no oncoming traffic, I turned left. Immediately as I pressed the gas pedal, truck started to sputter and engine light started flashing. Luckily no traffic coming up from behind and I had room to pull over and stop. However, since this is the SECOND time this has happened, I had my wife video the dashboard. Yep got it all on video. This has to be FIXED. Can't imagine if that were my kids driving and traffic was barreling up on them. Imagine a semi coming up at 60mph and no power or place to move out of the way. After stopping and turning off the truck, the issue went away. Coming home the same day, there were no issues. Closet Honda dealer is an hour away so I can't drop off conveniently. 2021 Honda RTLE, 3500 miles

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.

General Complaint - The infotainment system is terribly designed and requires way too much interaction from the driver to function properly. I just traded in my 2015 F150 for a 2021 Honda Ridgeline. EVERYTIME I choose to NOT connect my iPhone to the system through a USB to Apple Lightning cable, the system displays a warning that there is no device connected and will not show any other information until several specific buttons are pushed. Other scenarios where too many buttons needed to change settings. Too much interaction for a driver to do while safely operating the vehicle. I would replace the head unit but too many settings for the vehicle would be lost. Honda failed miserably in the radio design. Technology should help drivers, not hinder.

On this model of vehicle, if the vehicle dies and cannot be restarted, as an example if you are on a busy highway or intersection, there is no way to get the vehicle in Neutral so it can safely be moved WITHOUT having a special tool, Honda part #07AAA-TZ3A100. This tool is currently not available to purchase from any Honda dealer. This tool has to be used with the front hood open and reaching down and turning a bolt & manually locking the transmission in Neutral. The location of this bolt outside the truck & under the hood is also a hazard for the vehicle rolling and not being able to easily disengage it from neutral by having to get back out of the truck again and get under the hood. It is also a hazard to have to get out of the vehicle, on a highway or busy intersection or other hazardous area. In prior models of this vehicle, there was a method to manually put the vehicle in neutral while seated in the drivers seat, minimizing the risk of injury by having to get out of the truck and pop the hood. This is a very hazardous design flaw that should be remedied by Honda immediately. Honda should provide remedy to all vehicle owners and provide the method for manually putting the vehicle in neutral back inside the vehicle as it was in prior models as it is a safety hazard as it is designed now with the manual release under the front hood.

On June 3, 2022, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE22005 after the agency received VOQs and several field reports concerning the Auto Idle Stop (AIS) feature on 2016-2019MY Honda Pilot vehicles. The complaints allege that the engine fails to restart on its own from a complete stop at a traffic light or road intersection with the AIS function engaged. The subject vehicles are equipped with a 3.5L engine with a 9-speed automatic transmission. On January 6, 2023, Honda released service bulletins 23-008 and 23-009. These service bulletins address the failure to restart issue in the 2016-2019MY Honda Pilot vehicles, as well as the 2015-2020 Acura TLX, 2016-2020 Acura MDX, 2019-2022 Honda Passport, and 2020-2023 Honda Ridgeline vehicles. The repair outlined in the service bulletins is a two-stage countermeasure to remedy the issue. The first stage is a Programmed Fuel Injection (“PGM-FI”) software update. The second stage is only deployed if the software update fails to remedy the issue. The second stage, depending on the model and model year, consists of replacement of the starter assembly, starter relays, and a valve adjustment. Additionally, Honda extended the warranty coverage to 10 years with unlimited mileage for vehicles requiring the second stage component replacement. ODI continues to receive complaints of the AIS failure to restart, with many complainants alleging the campaign countermeasures had been completed.NHTSA has reviewed Honda's Information Request Letter responses involving warranty claims, lawsuits, and consumer complaints in addition to ODI's own data. This Engineering Analysis is being opened to further consider the potential safety defect, including gathering additional data regarding Honda’s service campaign efficacy. ODI is additionally expanding the scope to encompass all vehicles addressed in Honda’s service bulletins 23-008 and 23-009 as well as newer model year vehicles, which are substantially similar to the vehicles covered by the service campaign.

On June 3, 2022, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE22005 after the agency received VOQs and several field reports concerning the Auto Idle Stop (AIS) feature on 2016-2019MY Honda Pilot vehicles. The complaints allege that the engine fails to restart on its own from a complete stop at a traffic light or road intersection with the AIS function engaged. The subject vehicles are equipped with a 3.5L engine with a 9-speed automatic transmission. On January 6, 2023, Honda released service bulletins 23-008 and 23-009. These service bulletins address the failure to restart issue in the 2016-2019MY Honda Pilot vehicles, as well as the 2015-2020 Acura TLX, 2016-2020 Acura MDX, 2019-2022 Honda Passport, and 2020-2023 Honda Ridgeline vehicles. The repair outlined in the service bulletins is a two-stage countermeasure to remedy the issue. The first stage is a Programmed Fuel Injection (“PGM-FI”) software update. The second stage is only deployed if the software update fails to remedy the issue. The second stage, depending on the model and model year, consists of replacement of the starter assembly, starter relays, and a valve adjustment. Additionally, Honda extended the warranty coverage to 10 years with unlimited mileage for vehicles requiring the second stage component replacement. ODI continues to receive complaints of the AIS failure to restart, with many complainants alleging the campaign countermeasures had been completed.NHTSA has reviewed Honda's Information Request Letter responses involving warranty claims, lawsuits, and consumer complaints in addition to ODI's own data. This Engineering Analysis is being opened to further consider the potential safety defect, including gathering additional data regarding Honda’s service campaign efficacy. ODI is additionally expanding the scope to encompass all vehicles addressed in Honda’s service bulletins 23-008 and 23-009 as well as newer model year vehicles, which are substantially similar to the vehicles covered by the service campaign.

PE24004 · Rear-View Camera Failure
Opened Feb 13, 2024 · Closed Aug 5, 2024
Status: closed (inferred from source dates) · Back Over Prevention
On February 13, 2024, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE24004 to assess alleged failures of the rear-view camera (RVC) in 2020-2023 Model Year (MY) Honda Ridgeline vehicles. At this time, ODI has received a total of 50 complaints with allegations of the RVC image failing to display when the vehicle was in reverse. The RVC wire harness is routed near the hinge in the tailgate, in a location where frequent opening and closing of the tailgate causes bending stress on the harness. Honda determined the wire harness was manufactured with a material which is permeable to water and salt, which when it freezes and thaws, combined with tailgate usage, ultimately leads to breakage of the wiring in the tailgate harness. This results in a failure to display the RVC image. On May 9, 2024, Honda filed a Part 573 Safety Recall Report recalling all 2020-2024 MY Honda Ridgeline vehicles. The dealer will replace the RVC tailgate harness with a wire harness that is manufactured by a new supplier and has improved material properties to withstand wear from bending. In view of Honda filing recall 24V-321 addressing the subject of this investigation, ODI is closing this Preliminary Evaluation. NHTSA reserves the right to take additional action if warranted by future circumstances.
