Engine fails to restart after Idle Stop engaged. Engine stops normally when brake pedal is pressed and vehicle comes to full stop. Brake pedal is then released to restart engine but the engine does not start. Dashboard says "Shift to Park". The transmission is shifted to Park and then Start button is pushed to restart engine. Sometimes the Start button has to be pushed multiple times to restart engine. This is a safety issue because the vehicle cannot move in traffic, crossing an intersection, etc. It is equivalent to an engine stall. This happens approximately 10% of the time when the Idle Stop is engaged. Also, sometimes the engine will start but after a hesitation or a struggle to start. In this situation, "Collision Mitigation System Warning" displays on the dashboard. This happens probably 25% of the time. Battery and starter have no problem starting the vehicle outside of these conditions.

Several times over the past two months, I started having issues with the auto engine idle stop. I'm at about 25,000 miles and my vehicle has completely stalled out 4 times in two months. This is due to a failure of the auto engine idle stop system to restart the engine after I take my foot off the brake pedal. This has put my safety and others at risk in all of these incidents, all happened in busy, high traffic areas. In one instance it took a full minute to be able to turn my car back on. One time it triggered the collision system, and I couldn't restart my car for several minutes. After looking up this issue, I know there is an ongoing NHTSA investigation into the Honda Pilot models, but this needs to be expanded to the Ridge line models.

Beginning about 3 months ago the Automatic Idle Stop (AIS) would randomly not function at start-up during the length of a drive though there was no indication of any issue on the dash. Shutting off and restarting would allow usually allow it to function normally. About 6 weeks ago the AIS stopped the engine at a red light, and when I removed my foot to accelerate the engine did not start, the car shut off. It took a couple of seconds to realize the vehicle was down, I had to shut the car completely off and restart to get moving almost getting rear-ended since I did not move when the light changed even though my brake lights went off, confusing the driver behind me. AIS failing to start has become more frequent and now happens at least every other day. In traffic this is a safety issue for sure. Additionally, the LKAS system randomly displays a new message on the dash that it is disabled for a few seconds while driving on the freeway and then clears itself. Other seemingly related electrical issues started at the same time. On several of the occasions that the AIS failed to restart, All dash lights flickered rapidly, and the speedometer needle bounced wildly. after shutting down and restarting the A and B Trim computers had been zeroed as well as the MPG average being zeroed, and the Economy mode had been switched of. These nuisance electrical issues are not a safety concern themselves but may help point to a common failure which does cause the safety issues of the AIS and the LKAS systems. I believe you are investigating similar AIS issues on the Honda Pilot which shares many of the electrical and drive train components with the Ridgeline.

Engine
No restart after engine auto start/stop engages. Multiple times when the engine auto stop is engaged engine has to crank for multiple seconds to restart or won’t restart at all. This creates an unsafe condition when trying to make a turn at an intersection or when trying to turn onto a road from a parking lot.

On numerous occasions (at least 5 times) the following occurred: Upon exiting the highway after approximately 90+ minutes of driving, the truck's check engine light starts flashing and the vehicle goes into "limp mode" and will barely accelerate to avoid oncoming traffic from behind. The vehicle must be stopped and turned off to clear the engine light and return to normal performance. The on-board computer does not store any diagnostic codes when this occurs. There are numerous documented incidents exactly like this one on the Honda Ridgeline Owners forum. I have taken my truck to the dealer three times with no resolution. The dealer consults with Honda Tech support, who is unsure how to solve this issue. Assorted repairs have been documented on the aforementioned Honda forum, to no avail. This is definitely a safety issue when the truck loses power in traffic. I have almost been hit from behind while the vehicle is in limp mode. The initial occurence happened in November 2021 and most recently again April 16, 2022. Essentially for a year and a half Honda has done nothing to fix this problem.

Dealer claims unable to replicate, however I pointed out the smell to them once I arrived. Dealer mentioned that the smell was normal. They took the vehicle in anyway and claim again that the smell is normal. There are no warning lights or anything to indicate a problem. Smell first noticed around 5600 miles.

I understand my vehicle has a start and stop function. It does not work as it’s intended per Honda dealership and page 400s of the owners manual. My car is been shutting off randomly as I’m giving it gas moving forward ( 1 time) and we’ll over 10 times as I’m backing up into my driveway. When I am backing up, it’s normal and out of no where, my vehicle shuts off and it shifts back to neutral then starts to roll forward. When my truck shuts off as I’m in reverse, my reverse camera becomes audio or audio off when it’s suppose to show the rear camera back up. And my dash board, the oil light and battery comes on. I’ve brought it up to Honda dealership and I keep getting the run around. This is a safety concern! It’s a safety concern for myself, family and also the people around me driving if this happens to shut off on the freeway or even on the city road. I have my kids in the car and I could get crush from all directions if my car shuts off randomly. What do Honda need in order to fix this? My car getting crushed in an accident? Honda states they could not replicated it so I provided dash cam footage, live video footage. And still I’m getting the run around. Please help. Honda stated my after market parts caused this issue. But could not explain to me why and how it caused it?? I have a carb legal intake and an LED light strip. Nothing fancy! No harness no nothing! Just simple fuse power and ground. I’ve brought my vehicle in before for this issue ( with my carb legal intake) and Honda deemed it “safe and could not replicate it” so I carried on and installed my LED light strip properly. They could not explain it to me how my parts caused the issue. So I put my car back to stock specs as they recommended. And immediately my car shuts off like I stated in this. I did not buy a Honda to have issues. At this point I’m over owning this car. It’s brand new! There is a bigger issue. And I feel like I am wasting my time. At this point- I need more help.

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.

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.
