2024 Honda Ridgeline

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. To review the ODI reports cited in the Opening Resume ODI Report Identification Number document, go to NHTSA.gov.

I OWN A 2024 HONDA RIDGELINE TRAILSPORT. THE AUTOMATIC IDLE IS CONTINUOUSLY DRAINING THE BATTERY, MAKING IT HARD FOR THE TRUCK TO START. I HAVE PURCHASED 2 BATTERIES SINCE MAY 2024, WHEN I PURCHASED THE TRUCK. IT APPEARS THAT THERE IS SOMETHING WRONG WITH THE AUTOMATIC IDLE ON THE TRUCK, BUT HONDA TELLS ME THERE IS NOTHING WRONG. WHEN ACTIVATED, THE AUTOMATIC IDLE WILL SHUT DOWN THE VEHICLE IN TRAFFIC, CAUSING A VERY DANGEROUS SITUATION BECAUSE THE BATTERY DOES NOT HAVE ENOUGH POWER TO START THE VEHICLE WHENIT STALLS.

My husband was driving the vehicle to school with the sunroof shade closed. Without any impact or anything hitting the sunroof, it shattered. I tried filing a warranty claim with Honda, and they denied the claim without requesting any evidence.

The auto high beam is widely known to be so bad it behaves the opposite of how it should. It frequently blinds other drivers when it should not turn high beams on, often blinding them in the last few seconds before passing, causing a dangerous situation, not to mention the possibility of drivers thinking it was done on purpose maliciously. This has led to near road rage experiences. The high beams also rarely turn on when they should but at least there is a manual override.

My Honda CMBS system has false warnings from cars coming from the other lane and road markers setting off the system. I had numerous incidents where the steering wheel shakes and a brake warning illuminates with no possibility of an accident. After this warning the car would automatically brake to stop you. I have taken this vehicle to the dealer twice they said it is perfect. Honda knows this system is defective. In the owners manual they describe all the false warnings. I have experienced every one in the manual. I have begged the dealer and Honda company that I believe the camera mounted in front of the mirror is too sensitive and defective but they won’t replace it. The camera also controls the automatic bright lights and they won’t stay on for more than 6 seconds. I contend that this camera also sets off the emergency braking due to oncoming lights or reflective lights in the road. There is a class action lawsuit over this system up to a 2023 Ridgeline. All I want is a new camera and the Cmbs system to work correctly but Honda won’t repair it. They deny it is defective. They claim they can’t duplicate it. Of course they drive it once and say it’s fine. Please make Honda replace this faulty system
