Honda Prologue loss of power problems

Filed Aug 18, 2026 · Steering, Suspension · MI

When turning the vehicle, a clicking noise can be heard, intermittently. I have reported this to the dealership, they tell me they heard nothing. The car now has 20,000 miles and will need a tire rotation soon, I will then report it again. It appears the cv joint is the problem with many of these 2024 Honda Prologues. I’ve read, that a broken cv joint could cause loss of power, broken brake lines, and loss of control of the car. This clicking occurs mostly on hard turns, which I avoid due to potential damage and loss of control. There are no warning lights seen for this problem.

Subject: Safety Complaint – 2024 Honda Prologue – Clicking Noise When Turning (Possible CV Axle Defect) I am submitting a safety complaint regarding my 2024 Honda Prologue Touring due to a persistent clicking noise when turning, which appears to be related to the front axle or CV joint. Vehicle Information: Year: 2024 Make: Honda Model: Prologue Touring Mileage:10300 VIN: [XXX] Description of Issue: The vehicle produces a noticeable clicking/popping noise when turning left or right, especially at low speeds such as in parking lots or during tight turns. The noise is consistent and reproducible. The issue appears to originate from the front axle/drivetrain area and raises concern about potential failure of a critical drivetrain component. Safety Concern: This defect may indicate premature wear or failure of the CV joint or axle assembly. A failure of this component while driving could result in loss of power to the wheels and create a dangerous driving condition, increasing the risk of an accident. Dealer Response: I brought the vehicle to an authorized Honda dealership. The dealer acknowledged the issue but stated that no repair or fix is currently available and advised me to contact Honda directly. The issue remains unresolved. Additional Notes: Based on my research, multiple other owners are experiencing similar issues with the same vehicle, suggesting this may be a widespread defect rather than an isolated incident. I am requesting that the federal safety agency investigate this issue as a potential safety defect affecting the 2024 Honda Prologue. Thank you for your attention to this matter.

This issue has occurred twice. The first time was at approximately 3,000 miles, and the second time at around 7,200 miles. On both occasions, the vehicle lost power and displayed a warning message stating “Service High Voltage System” along with a “Reduced Speed” notification. During these events, the estimated driving range dropped significantly, charging was limited to approximately 25%, and acceleration was severely restricted, indicated by a turtle icon on the dashboard. After the first occurrence, the vehicle remained undrivable for approximately three days over Thanksgiving. By the time I was able to bring it to the dealership on the next available business day, the warning light had turned off. I was advised to bring the vehicle in immediately if the issue happened again. The issue did not reoccur for about three months. When it happened again, I was out of town and the estimated range dropped from over 100 miles to around 60 miles. I was able to make it home without requiring a tow and brought the vehicle to the dealership the following day. At check-in, the service advisor observed that the warning lights were still active. However, later that day I was informed that by the time the vehicle was inspected, the warning lights had turned off, and no action could be taken. Based on information found in online owner forums, this appears to be a known issue potentially related to a defective component. It has also been suggested that the issue is more likely to occur in colder conditions. Due to the unpredictability of this failure and the loss of power and range when it occurs, I do not feel confident in the reliability of the vehicle, particularly for longer trips or travel in remote areas.

The CV axles on my vehicle are making a loud, rhythmic clicking noise, especially when accelerating or turning. This issue has become progressively worse and is now occurring during most driving maneuvers. My primary safety concern is a catastrophic mechanical failure where the axle could break or seize while the vehicle is in motion, leading to a sudden loss of power to the wheels or a potential loss of steering control. This poses a significant risk of a crash on the road.

On March 18, 2026, while driving a leased Honda Prologue in rush-hour traffic on a major highway in [XXX] , the vehicle suddenly shut down and would not restart for approximately two minutes. The incident occurred without any warning messages, alerts, or notifications and created an extremely dangerous situation. At the time of the incident, traffic had been stop-and-go for approximately three miles. Without warning, the radio turned off, all dashboard lights went dark, and the vehicle lost power and stopped moving. I attempted to restart the car multiple times, but it would not turn on. On approximately the seventh or eighth attempt, the vehicle finally restarted, allowing me to safely pull off the highway. Fortunately, the slow-moving traffic prevented a rear-end collision with vehicles behind me. I began leasing the vehicle this past summer, and at the time of the incident it had fewer than 2,600 miles on the odometer. I took the vehicle to the dealership that same evening. During their inspection, the dealership identified several “Lost Communication” diagnostic trouble codes in the vehicle logs. The most significant code identified was B1B42 – Start/Stop Switch Not Plausible. The service team also noted that the manufacturer’s troubleshooting checklist references codes B1B15 or B1B15 2A; however, those codes were not present. Based on the findings, the dealership replaced the S38 Start/Stop Switch. I resumed driving the vehicle two days ago and have not yet experienced any further issues. However, I remain extremely concerned about the seriousness of this failure. If this same issue were to occur again at higher speeds or in faster-moving traffic, it could result in a severe accident. The complete loss of power without warning represents a significant safety risk and warrants further review.

My vehicle began producing loud clicking and popping noises from the front drivetrain during low-speed turns and acceleration around October 2025 at approximately 8,000 miles. I brought the vehicle to a Honda dealership for inspection, where the service department confirmed that both front CV axles were defective and recommended replacement. The replacement parts were initially backordered but have since arrived at the dealership. However, Honda has informed the dealer that the company is currently investigating this issue and does not consider it a safety concern at this time, and dealers have been instructed not to replace the axles unless there is obvious physical damage. As a result, the dealership has not repaired the vehicle despite diagnosing both axles as defective. I am concerned that premature failure of both front axles could lead to drivetrain malfunction or loss of power to the wheels while driving.

Broken/Clicking CV joints. This could lead to all loss of power transfer to the wheels, causing a sudden and unexpected stop to the vehicle while driving. Honda is aware of this defect, but has no permanent fix. This is confirmed by multiple Honda Service Centers. High Voltage Warning. Loss of heat, car will not charge, car shuts down/becomes undrivable, or enters "limp mode." This is an extreme safety issue. The car loses the ability to properly cool the main battery. This could result in thermal runaway (a rapid, uncontrollable, and self-sustaining increase in battery cell temperature), resulting in a fire that is difficult to extinguish, burns extremely hot, may reignite hours or days after the initial incident, and/or result in explosion. This is confirmed by multiple Honda Dealerships. The warning has occurred multiple times, even after multiple repair attempts.

Vehicle Information Year: 2024 Make: Honda Model: Prologue Purchase Date: February 10, 2025 Mileage at Time of Issue: Approximately 40,654 miles Date Problem Occurred: February 19, 2026 Complaint Description: I purchased a brand-new 2024 Honda Prologue on February 10, 2025. On February 19, 2026, I received a warning message on the dashboard that stated “Service High Voltage System.” At the time the warning appeared, the vehicle had approximately 40,654 miles on the odometer. This warning concerns me because the high-voltage system is a critical component of the vehicle’s electric power train. A malfunction in this system could potentially affect the vehicle’s ability to operate safely, charge properly, or maintain normal performance. Since this is an electric vehicle, any issue with the high-voltage system could create a safety risk, especially if the vehicle were to lose power or fail while driving. I am submitting this complaint so the issue can be documented and investigated in case other 2024 Honda Prologue vehicles experience the same problem. At the time of submitting this report, I am not aware of a recall addressing this issue. I will be taking the vehicle to a Honda dealership for inspection and will keep records of any diagnosis, warning codes, or repairs related to this problem.

During a normal commute on the highway, the vehicle suddenly lost all engine power and stalled in the middle of high speed traffic. The vehicle could not exceed 8 mph while attempting to pull to the side of the road for safety. There were no warning lights (other than a low tire pressures - normal for cold days) and no error messages. The car was unable to get started for about 10 minutes. Eventually, the engine started and the vehicle was able to make it back to our residence. The battery was near 55% at the time of the incident (out of a maximum of 80% recommended charge) In terms of safety, this was a near fatal incident, as suddenly losing power and stalling in the middle of the highway during high speed traffic and snowy conditions could have been devastating.
