2025 Honda Prologue

Vehicle was taken to dealer for click noise Hurd while turning right around only 4k miles. The dealer confirmed the noise using a mechanics ear they said as of right now no replacement has been authorized. Honda is investigating. January 2026 car started clicking while in curves and any movement in steering. Still no fix. March 2026 still not fix because Honda hasn’t investigated yet and now my system has horrible issues with the auto break and rear collision avoidance system. Hondas “fix” turn it off. Why wouldn’t get a touring model with all those features just to have them tuned off.

My 2026 Honda Prologue makes clicking sounds when executing turns. The problem was confirmed in a diagnostic assessment at the Honda dealer at about 7,500 miles (2/4/26). The service rep. said Honda was looking into the problem (CV joints/bearings), but there was no current solution, and they would contact me when a solution became available. The rep. said Honda did not consider this a safety issue. I also own a Honda Civic that has made almost identical clicking noises when its CV joints were failing. In those cases, the Honda dealers always stressed the problem needed addressing in a timely manner as failing CV joints could pose a significant safety hazard. Why has Honda adopted a contradictory stance regarding this CV joint issue with the Prologue? I would urge the NHTSA to investigate the problem (widely reported on Prologue user forums) to determine if it constitutes a safety issue. If confirmed, I would encourage a formal safety recall be implemented to protect the public. This would also help ensure Honda rolls out a solution while the vehicles are still under warranty. (Vehicle is available for inspection by NHTSA and/or manufacturer.)

The vehicle has twice displayed a “Service High Voltage System” warning followed by “Reduced Acceleration – Drive With Care.” When this occurs, the vehicle enters a reduced-power (turtle) mode that severely limits acceleration. Cabin heat also stopped working, and the vehicle would not charge beyond approximately 25%, restricting driving range. OnStar diagnostics reported a critical error. The vehicle and diagnostic history are available for inspection upon request. The first incident occurred while driving around town. Although I was close to home, the reduced acceleration created concern because the vehicle could not respond normally to traffic. The second incident was significantly more dangerous and occurred in heavy traffic and on the freeway about 40 miles from home during heavy rain. The limited acceleration made merging and maintaining a safe traffic speed difficult, placing myself and others at risk. I have only been able to get the dealer to take the vehicle in one time, specifically for this issue, and that was because the warning lights were still on at arrival. Staff observed the warnings at check-in, but by the time the vehicle reached the service area, the lights had cleared. The dealer stated they could not perform repairs without active warnings, though stored codes reportedly indicated a low-voltage condition. Additionally, a clicking noise from the wheel area began about 1,500 miles ago and occurs consistently when turning, similar to a CV axle concern. During a separate visit, the dealer put in writing that they could not do anything about the noise and did not diagnose or inspect it, which left me uneasy about potential drivetrain safety. The intermittent high-voltage fault, reduced acceleration, charging limitation, loss of heat, and unresolved drivetrain noise create ongoing safety concerns due to the unpredictable nature of the failures.

I am reporting multiple safety-related failures with my 2025 Honda Prologue. The vehicle has an unresolved drivetrain/axle defect that affects safe operation, and the dealer has stated that axle components are on backorder with no repair timeline. In addition, the main vehicle control screen completely blacked out and will not turn back on. This screen controls critical vehicle and charging functions. Without it, I cannot control charging or access essential vehicle systems, rendering the vehicle unsafe and effectively unusable. Further, the charging port sensor failed to alert me that the charging port was open. Because no warning was provided, the port remained open and subsequently broke. This represents a failure of a safety-related sensor system that directly impacts the vehicle’s ability to charge and operate properly. The dealer has not provided a loaner vehicle or alternative transportation despite the vehicle being unsafe to operate. These combined defects substantially impair the safety, use, and value of the vehicle.

Within 1K miles, both CV joints began to "click" when doing low speed turns -- or accelerating while turning. This is a VERY widely documented issue with the Honda Prologue. Just took the car in to my local (Honda Marin) dealership (car now has 5K miles). They verified the issue but stated Honda of America had no fix at this time -- and that it wasn't a safety concern. I'm not sure how this can be true -- when a CV joint fails, you no longer have power to the wheels.
