ELECTRICAL SYSTEM

2024 Honda Ridgeline, VIN [XXX], approximately 21,000 miles. The vehicle has repeatedly failed to restart in traffic after the Auto Idle Stop system automatically shut off the engine. Failures occurred XXX. During one occurrence, I was nearly rear-ended when the vehicle failed to restart as traffic began moving. The vehicle also intermittently cranks abnormally slowly when hot. The starter will crank, pause, then crank noticeably slower. I can intermittently reproduce the fail to start problem by driving until the vehicle is hot, shutting it off, and immediately restarting it. I have two videos of this condition. Honda replaced the battery, but the problem continues. The dealer reports that the battery, alternator, and starter pass diagnostic testing. I provided video documenting the abnormal slow cranking and failure to start, but no repair has been made. My primary safety concern is that Auto Idle Stop automatically shuts off the engine while stopped in active traffic, but the vehicle may then fail to restart, leaving it disabled in a traffic lane. The vehicle has already experienced this failure three times. NHTSA is currently investigating Auto Start/Stop no-restart complaints involving 2020–2025 Honda Ridgelines under EA25-004.

POWER TRAIN,ELECTRICAL SYSTEM,ENGINE

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 has been identified. The vehicle now intermittently cranks slowly and appears strained while starting. No permanent repair has been completed. The vehicle is available for inspection. The condition creates a safety risk because the vehicle can fail to restart or move from an intersection and may enter Neutral unexpectedly.

VEHICLE SHUTS DOWN WHILE IN IDLE AT STOP LIGHT

ELECTRICAL SYSTEM

While stopped at a red light, the auto on/off feature engaged and the engine shut off. Upon release of the brake, the engine failed to restart.

ELECTRICAL SYSTEM,ENGINE

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

ELECTRICAL SYSTEM,ENGINE

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

POWER TRAIN,ENGINE

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.

UNKNOWN OR OTHER

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.
