IllustrationThe forward collision system frequently goes off from a vehicle simply driving in their lane normally. The truck alarms, shakes the wheel, and sometimes brakes automatically. This is alarming for my kids riding in the car and the braking is dangerous for cars behind me. This could cause a rear end collision.

Engine began knocking from the bottom end at 53k miles. It was determined that a connecting rod bearing had failed and Honda is replacing my engine under warranty. No cost was incurred to me but I am adding my complaint because my VIN is not included in the recall for this exact problem in other years close to mine and the recall my need to be expanded to a wider range of VINs.

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 Issue and Honda needs to expand the recall to cover my VIN and any other VIN's that are affected by this defective High Pressure Fuel Pump.

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.

My 2021 Honda Ridgeline engine failed in heavy traffic on the freeway. The car malfunctioned and I lost complete power and started coasting and barely made it through 4 lanes of heavy traffic before the car coasted to a stop. Very dangerous and very lucky not to get hit changing lanes and then waiting on the freeway for assistance. I've made regular oil changes as directed by the computer on the vehicle. The problem was not connected to a lack of oil. I'm [XXX] and I take very good care of my vehicles. Not one scratch on my black edition Ridgeline. My vehicle is still at the Honda dealership. I don't believe I should pay for another engine nor do I have the money to do so. Having a complete engine failure on the freeway is a major safety issue and Honda needs to fix it now and in the future. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

This has something to do with circuit board for the seat sensor that activates air bag? I can’t get dealer to take care of recall. They keep saying we don’t have the parts. This is going on since at least September of last year. Why have recall if they aren’t going to do anything about it? They make appointments and then cancel. I have called Honda Customer Service number(twice) listed on the recall paper twice. Always get told to call dealer and talk to them. Dealer makes appointment and then cancels a few days before the date to bring it in. I have contacted dealer many times about this. Why issue a recall and then don’t fix anything?

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 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.
