Filed Nov 9, 2026 · Engine · TX

While stopped at an intersection during heavy traffic, 2024 Honda Ridgeline auto restart feature failed and the engine died. This feature should restart the engine from its full stop, but failed to do so. A system failure message appeared. I had to put vehicle in park in heavy traffic, and restart the vehicle manually. Autos behind me had to go around me for a short time.

Engine start is sluggish especially when at operating temperature. This especially occurs with the auto idle stop feature. Starter appears to be over heating due to its location next to exhaust. Bad design.

Vehicle Safety Complaint – 2024 Honda Ridgeline Vehicle: 2024 Honda Ridgeline AWD Sport VIN: [XXX] Issue: Engine stalls at traffic lights and fails to restart automatically. My 2024 Honda Ridgeline has a recurring and potentially dangerous problem with the Auto Idle Stop system. When I come to a complete stop at a traffic light or intersection, the engine shuts off as part of the Auto Idle Stop function. However, when I release the brake pedal to continue driving, the engine sometimes fails to restart automatically. When this happens, I am unable to move forward with traffic. I must shift the transmission into Park (P) and manually restart the engine before I can drive again. This leaves my vehicle unexpectedly immobilized at intersections, creating a safety risk for me and other motorists. This problem has occurred repeatedly since XXX. On XXX, [XXX] Honda inspected my vehicle at approximately 22,402 miles. The dealership verified the complaint and replaced the starter motor and two starter relays. Despite these repairs, the problem returned. The battery was also replaced in XXX, but the issue continued. During a subsequent dealership visit in XXX, technicians were unable to reproduce the problem. However, the vehicle continued experiencing intermittent engine shutdowns and failures to restart. On XXX, I returned to the dealership because the problem remains unresolved. I was informed that Honda may be planning a recall related to this issue, although I have not received confirmation of an official recall. My primary concern is that the engine unexpectedly fails to restart while I am stopped in traffic, leaving me unable to accelerate when the traffic light changes. I am requesting a thorough safety investigation and a permanent repair. Previous repairs have not corrected this recurring defect.

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 starter motor suffers from electrical heat-soak. When the engine is fully warm, the vehicle fails to restart manually. This leaves the vehicle stranded and vulnerable at gas stations, intersections, or in heavy traffic conditions after the vehicle is shut off. The manufacturer's dealership cannot reproduce it because they only test the battery cold, leaving a known defect unaddressed on a vehicle still under factory bumper-to-bumper warranty. This starter happening occasionally but now anytime it is hot it fails to restart or restarts very slow.

Initial Mechanical Issues – September 2026 In September, while slowing down at a traffic light, my Ridgeline unexpectedly shifted into Park on its own. I was forced to turn the vehicle completely off and restart it before I could continue driving. In addition to this dangerous incident, I experienced several other electrical and mechanical problems: •The high beams would activate unexpectedly, even when another vehicle was directly in front of me. •The driver's side window would move up and down without being prompted. •The vehicle began hesitating when starting in the mornings, behaving as though it had an aging or failing engine. Second Dangerous Incident – October 13, 2026 Approximately one month later, the vehicle again began experiencing difficulty starting and shifting gears roughly. On October 13, while slowing down at a traffic light, my Ridgeline unexpectedly shifted into Neutral on its own. A message appeared on the dashboard instructing me to press the brake pedal and shift into Park. My vehicle became disabled in the middle of the roadway, leaving me in an extremely dangerous situation. I was nearly struck by a semi-truck while sitting helplessly in traffic. The vehicle displayed a dead battery warning, despite the battery having been replaced only one month earlier. I repeatedly attempted to restart the vehicle using the push-button ignition. After approximately ten frightening minutes stranded in the roadway, the vehicle finally restarted. This incident could have resulted in serious injury or even the loss of my life.

In August 2026, my 2024 Honda Ridgeline Black Edition became undriveable while traveling in stop‑and‑go traffic on a four‑lane interstate. Without warning, the vehicle shut down completely and would not restart. After multiple attempts, it eventually restarted, but the shutdowns continued several more times during the same trip. The local Honda dealership retrieved diagnostic codes indicating software and transmission faults related to the auto stop/start system. They reinstalled the vehicle’s software. Several weeks later, similar failures occurred again involving the stop/start system. During the second evaluation, the dealership diagnosed the starter motor electrical connections as the source of the fault, noting that the starter was drawing excessive amperage. Replacement parts were no longer available from Honda and took several weeks to obtain. After replacement, the vehicle continues to experience electrical malfunctions, including unexpected computer reboots when coming to a stop. The issue remains unresolved, and the vehicle continues to pose a safety risk due to unpredictable shutdowns and electrical instability.
