Never works since bought on May 30, 2021, Wireless charger getting connected and disconnected every 15 seconds, makes the phone hot and not charging. Can be check it at any time. The dealer replaced the wireless charger already and still with the same problem, phones tested: iPhone pro max, Samsung s21 ultra, Google pixel. The dealer can't find a solution, it is thousands of people with not only Ridgeline 2021 but Pilots, Accord, Civic and Odyssey. They know the problem but still selling the vehicles like that.

I have a 2021 Honda Ridgeline Sport equipped with CMBS an automatic braking system that is supposed to be a safety feature, but actually makes the car more dangerous. The problem with the Ridgeline Sport collision mitigation braking system is that it attempts to mitigate crashes when the system thinks an obstacle is ahead, but it is a false warning, and there are no actual obstacles. It appears there is a software or sensor defect in the Honda Sensing technology causing the vehicle to issue warnings and alerts to the driver and the potential to automatically hit the brakes without warning when there are no obstacles in front of the vehicle and it has not deviated from its lane. Service Advisor/Mechanic at dealership called it a computer glitch. Nothing they can do. Taking it back again to have it on record; dealership tried to fix vehicle. This vehicle is potentially dangerous with no way to correct concern at this time. Problem continues since March 2021.

WHILE DRIVING AT NIGHT EVEN WITH NO TRAFFIC AHEAD, THE AUTOMATIC HIGH BEAMS RARELY TURN ON. WHEN THEY DO, THEY TURN OFF ALMOST IMMEDIATELY DUE TO REFLECTIONS FROM ROAD SIGNS AND EVEN SMALL ROAD MARKERS. OCCASIONALLY, THEY'LL FAIL TO DIM IN A TIMELY FASHION OR WILL FLASH CAUSING OTHER DRIVERS TO THINK I'M DOING THIS ON PURPOSE. OTHER OWNERS OF 2020 AND 2021 HONDA RIDGELINES ARE REPORTING THE SAME USELESS AND UNSAFE OPERATION. I OWNED 2017 AND 2019 HONDA RIDGELINES WITH AUTOMATIC HIGH BEAMS AND THE FEATURE WORKED REASONABLY WELL. FROM 2017-2019, HONDA USED A DEDICATED CAMERA FOR THE AUTOMATIC HIGH BEAM FUNCTION. FOR THE 2020 MODEL YEAR, HONDA ELIMINATED THIS CAMERA AND MERGED THE AUTOMATIC HIGH BEAM FUNCTIONALITY INTO THE "MULTI-PURPOSE CAMERA UNIT" THAT IS ALSO USED FOR OTHER FUNCTIONS SUCH AS THE LANE KEEPING ASSIST SYSTEM FEATURE OF HONDA SENSING. IN SHORT, THE NEW AUTOMATIC HIGH BEAM SYSTEM IS NOT ONLY USELESS, BUT OFFENSIVE TO OTHER DRIVERS. I'M AFRAID THE FLASHING WILL INDUCE ROAD RAGE OR GAIN UNWANTED ATTENTION FROM LAW ENFORCEMENT OFFICERS. FOR NOW, I HAVE DISABLED THE AUTOMATIC HIGH BEAM SYSTEM. THE 2021 RIDGELINE'S HEADLIGHTS ARE ALREADY A STEP BACKWARDS ACCORDING TO IIHS TESTING (AND MY OWN OBSERVATIONS) AND I FEEL LIKE THE "HIGH BEAM ASSIST' CREDIT THEY APPLY SHOULD BE REMOVED SINCE THIS FEATURE IS NEXT TO USELESS SINCE THE 2020 MODEL YEAR.

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.
