2024 Honda Ridgeline

When stopped at a stop light the auto start feature sometimes - more often than not- fails to start back and the truck is stuck at the intersection. After putting it in park it will start after several tries. My dealership tells me there is nothing wrong with it even though it’s still under warranty. This has happened over 10 times to me

Receiving pop up faults on instrument panel. ie battery low voltage, adaptive cruise sys problem, road departure mitigation sys problem, Sys problem detected shift to park, to start engine brake and push start, idle stop engine will not restart all of these issue donot throw codes to the main ECM or BCM so dealer can't trace the problem. This has been going on since march 2025

My vehicle is currently sitting at a Honda dealership with a broken crankshaft counterweight and seized bearing. The engine needs to be replaced but Honda has refused to conduct the dealership warranty and blame shift it to a cracked oil pan that had happened in November of last year that was quickly addressed. Since then I have gone to [XXX] and back to [XXX] showing the vehicle was fine and operating. It is to my understanding that my 2024 Ridgeline has a 3.5L J-Series V6 engine. The NHTSA is actively investigating over 1.4 million Honda V6 engines for this exact connecting rod bearing seizure defect. I feel it is wrong for the dealership to pin a known defect on something unrelated and have insurance pay and avoid conducting the warranty repair. My vehicle is sitting at 39,000 miles and I was on a normal commute to work when the incident occurred and still covered under factory warranty.

Truck fails to restart after the auto idle shut off. The battery goes dead and I cannot restart. This has happened several times so I now turn the Idle Off feature off. However, since it does not stay off permanently, if I forget to turn if off the truck may fail to restart. It has left me stuck at intersections unable to restart on several occasions.

After coming to a stop and the idle stop feature engages, the vehicle does not automatically restart. I am presented with a message that says "system problem detected. shift to park". After shifting to park, I am presented with another message that says ""to continue to drive, depress the brake pedal and push switch." I then have to completely shut off the engine by pushing the "stop button". Then, I have to do a full restart before the vehicle starts again. This has happened 5 times in the last month. Here is a video of one incident - [XXX].[XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2024 Honda Ridgeline. The contact stated that while stopping at a red light, the Auto START feature failed to restart the vehicle, and the vehicle started rolling backwards. The brake pedal was depressed, and the PUSH to START button was depressed, and the vehicle was restarted. The dealer was contacted; however, the vehicle was not yet diagnosed or repaired.

The contact owns a 2024 Honda Ridgeline. The contact stated that while attempting to start the vehicle with the Push-To-Start feature, the vehicle failed to start. No warning light was illuminated. Additionally, while idling in traffic, the vehicle lost automotive power and failed to accelerate as intended while the accelerator pedal was depressed. The vehicle was restarted as a temporary fix. Upon further inspection, the contact became aware of an abnormal electrical burning odor entering the cabin of the vehicle. The vehicle was taken to a local dealer, where it was diagnosed; however, no cause for the failure was found. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 35,000.

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.

Windows and moon roof on 2024 Honda Ridgeline opens when parked. Lock button on Key fob is supposed to be pressed twice to activate this feature but opens when fob is on desk or in my pocket. No damage yet but could cause problems for theft or rain damage if parked outside when unattended

2024 Honda Ridgeline. Brakes stick or slow to release. Feels like brakes are dragging. Delayed acceleration. This is unsafe. Dealer has had vehicle 7+ days total across 2 repair attempts from March 25th 2026 thru April 1st 2026 and again April 29th 2026 and dealership still has the vehicle. Has not been able to fix the issue. Honda issued Dealer Message on August 7, 2025 stating "American Honda Motor Co.,Inc. is searching for certain 2023-2025 Odysseys, Passports, and Ridgelines with a customer complaint of the brakes sticking. Vehicle purchased April 1st 2024 and has 12,700 miles. Currently at dealership for 2nd attempt. this is a known safety defect Honda is actively investigating. Sticking brakes crash risk. Delayed acceleration. Feeling of brakes dragging. Ongoing intermittent issue. I have been offered a loaner vehicle on both occasions.

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.

LIGHTED RUNNING BOARD LIGHTS CONTINUOUSLY QUIT WORKING. HONDA HAS A TECHNICAL SERVICE BULLETIN ISSUED BUT THIS IS A KNOWN PROBLEM.

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

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.

The Auto High Beams (AHB) fail to work correctly. When set to on, they will come on for maybe 3-4 seconds then turn off, and maybe repeat the next time. The bigger issue is they fail to turn off many times when approaching oncoming traffic. The feature is dangerous by not turning on when they should and not turning off when they should. This is a widespread problem reported by many. The Honda dealer said they adjusted the sensitivity of the AHB when in fact there is no such adjustment. There is clearly something wrong with the implementation on the Ridgeline as other same year Honda models (we have a 2924 CRV) do NOT have this problem.

Vehicle has stalled after being stopped at red light. Does not occur all the time. Only when in idle mode.

Auto Start/Stop Malfunction. On two occasions the Auto start/stop has shut the engine off at a stop light and after releasing the brake the vehicle went completely dead. Dashboard/radio and all electronics dead. After multiple attempts the vehicle finally restarted. Now the normal start is sluggish like a low battery. Battery was replaced under warranty and check out multiple times by the dealership with them not able to find any issues.

The vehicle’s engine and powertrain management system repeatedly fails with multiple DTC's triggering a full-system cascade of safety-critical warnings and automatic power-limiting. The issue affects the engine, transmission, emissions, AWD, brake system, stability assist, steering assist, ABS/VSA, hill-start assist. The vehicle is fully available for inspection upon request. During each failure, the vehicle abruptly enters reduced-power “limp mode” without warning—resulting in loss of engine power, disabled AWD, and disables all safety/stability systems. These events have occurred in normal traffic, including at red lights and in intersections, creating a risk of rear-end collisions, inability to accelerate, and loss of vehicle control. I transport an autistic child, making reliability and predictable vehicle behavior critical to passenger safety as well. The problem has been reproduced and documented by multiple authorized Honda dealerships. The vehicle has now undergone 13 repair attempts in the first 14 months of ownership, across 6 different Honda dealerships. All have been unable to diagnose or permanently repair the defect. The vehicle has been repeatedly inspected by Honda technicians, who escalated the issue to Honda Tech Line. Tech Line documents (dated 10/1/25) show that no aftermarket modifications exist and that the failure is verified but intermittent and ongoing. Warning Lamps / Symptoms: Each failure event triggers a full dashboard sweep including: – AWD System Problem – Emissions System Problem – Transmission System Problem – Power Steering System Problem – Vehicle Stability Assist Problem – Hill Start Assist Problem – Brake System Warning – Road Departure Mitigation Problem – Blind Spot Information System Problem There is a federal lawsuit filed filed in Oregon District court case 6:25-cv-02142-AP

Between 1,000-1,400 rpm there is a lower end engine knock.sounds like a bearing.
