2024 Honda Ridgeline problems

“Vehicle purchased in June of 2024, and with auto start in normal state (not disabled) vehicle does not restart (as it is designed to) when stopped at a stop light. I will have to put the vehicle into a parked state and then attempt to restart it. Fortunately I have not been rear ended yet, but it has caused delays in traffic having to attempt to complete this to get the car running again. Does the 2012 EPA rules and "off-cycle" credits that encouraged automakers to adopt automatic start-stop systems to reduce emissions really help people from possibly getting hit at a stop light/stop sign. I know I can turn it off, but if I turn it off why does it turn on automatically when the engine shut off and is restarted again.”

“The restart function on this vehicle doesn’t work. Will leave you stalled in traffic. Multiple events in this vehicle for me. Problem recognized for older models but not 24-25 yet. Same exact issue though”

“The Automatic High Beam system does not work properly and are very inconsistent. When enabled, the high beams often turn on for a brief moment then turn off. Sometimes this occurs when there is a road sign reflection or a light on a home on the side of the road. When the system is enabled, the high beams often fluctuate on and off even when there is no oncoming traffic. What is worse is that the high beams sometimes remain on with oncoming traffic, blinding the oncoming driver. I am reporting that this has occurred ever since I purchased the vehicle in 2024. The dealer indicated this is a known problem and that Honda doesn't seem to be doing anything about it.”

“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.…”

“The system in question and failing is the idle-stop engine, start function. The truck is available for inspection upon request. The idle-stop engine has failed to restart the engine several times in traffic and at stop lights. This has created a safety hazard, since even after completely shutting down the vehicle (all power off), it has taken multiple tries to restart. The starter becoming increasingly harder to start each time. The problem has been reproduced by Hagerstown Honda, [XXX] where I purchased and have the vehicle serviced. Vehicle has been inspected by the manufacturer's representative -- Hagerstown Honda. There were no warning lamps, messages, or other symptoms of the problem prior to the failure. This issue began occurring in XXX, after owning the vehicle just over two years. Issue has occurred multiple times in traffic in [XXX] and on surrounding roadways. Current fix is to always remember to disengage this system. However, the starter is becoming increasingly weaker in its ability to turnover the engine which is very concerning.”

“I am reporting a recurring Auto Idle Stop no-restart and starting-system failure in a 2024 Honda Ridgeline. At approximately 35,072 miles, while stopped at a traffic light with Auto Idle Stop engaged, the engine shut off but failed to restart when the brake pedal was released. The vehicle remained disabled in the intersection until it was manually restarted, creating a risk of a collision. An authorized Honda dealer found both positive and negative battery terminals loose, tightened them, reported that the battery passed a load test, found no diagnostic trouble codes, and returned the vehicle. The battery had already been replaced at approximately 30,238 miles after a slow-start complaint and a failed battery test. The condition recurred at approximately 42,563 miles. After the engine shut off at a light, the vehicle displayed an orange “P” and “System Problem Detected - Shift to Park,” went into Neutral, and required a manual restart before Drive could be restored. The dealer later reported that the replacement battery tested at approximately 197 CCA against its 650 CCA rating, but no root cause for the rapid deterioration or the shutdown/no-restart condition…”
