Auto High Beam. Very sensitive. Sometimes they don't go on when they should and sometimes, they stay on blinding oncoming traffic. I have researched this problem and also have been told this is a known problem with this particular model and year - not just my vehicle.

Headlights don't dim in the auto function when there is oncoming traffic. Lights cycle from dim to bright when no oncoming traffic is present. This is an ongoing problem that presents every time the vehicle is driven at night.

My model has an auto high-beam system that does not work (stays on with oncoming traffic, turns off when it sees a road sign). Also had a 2019 of the same vehicle and the auto high-beams worked on that model; my 2021 has the cameras in a new location which render the system worthless and dangerous.

The auto dimming feature on my ridgeline does not operate properly. Does not dim when on coming traffic approaches sometimes, and others do not stay on when it should. This has happened since I took possession of the vehicle and still happens today.

The auto-highbeam feature does not operate properly. The highbeams are frequently engaged when an oncoming car is no more than 300 feet away. This irritates the oncoming motorist and creates a dangerous situation causing risk of a crash. The auto-highbeams also have a tendency to switch to low beam at inopportune times because the glare from roadside signs is recognized as an oncoming motorist.

The 'automatic high beam/low beam' function is totally worthless. Any reflective sign along the road turns the high beams off. The system on my earlier 2017 Honda Ridgeline worked almost 100%. This 2021 system basically doesn't work. In addition you must reach 45 mph before it activates. On many of the back roads that I travel on, the speed limit is less than 45 mph. I have heard that Honda changed the system on the 2021 model. Bring back the older system (my 2017), or don't feature it all. It's non-functional and Honda should not be allowed to advertise it!

Automatic high beam lights system is terribly dangerous! Not even close to working as advertised. They do not drop to low beam with virtually all oncoming traffic. They are constantly tricked and flicker when looking at reflective signage. They create confusion and very dangerous distraction. This is a well known design flaw with these late model Ridgelines and the dealers can’t do anything to correct. Please convince Honda Motors to correct this dangerous situation soon.

Vehicle is equipped with automatic high-beam headlights. The feature has not worked properly since I bought the truck new in April 2021. Hi-beam lights will activate for a few seconds and then turn off for about 10 seconds and continually repeat the sequence regardless of road specifics. A few times, the headlights have flashed oncoming vehicles less than 100 feet away. I have taken the vehicle in for repair three times to two different dealers and contacted Honda Customer Assistance for advice. The dealers have the same response after each repair: We have no guidance from Honda how to fix and cannot do anything. Honda Customer Service has no provided any solutions so I am forced to disable the feature to avoid the issue of flashing oncoming vehicles. I have also posted You Tube videos of the behavior hoping that it would help the service folks. They acknowledge the behavior but cannot fix: https://youtu.be/Zmv23FX4R20 https://youtu.be/Kp623lKKAXs https://youtu.be/W3Tfnh1MNeY https://youtu.be/JyGZx13JjX4 https://youtu.be/8sfLcZWPwec

Status: open (inferred from source dates) · Engine And Engine Cooling:engine; Engine And Engine Cooling:engine:crank/camshaft Position Sensor; Engine And Engine Cooling:engine:engine Control Module (ecu/ecm):software; Engine And Engine Cooling:engine:hard Parts Internal/mechanical

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.
