2025 Honda Prologue Reliability Report

Most of these reports say the backup camera is too dark to use at night, even at maximum brightness and with working reverse lights. Dealers and Honda say nothing can be done. Other reports repeat problems filed elsewhere: high-voltage system errors, "Reduced Acceleration" warnings, and axle clicking during sharp turns. One owner says the HondaLink app keeps showing "data unavailable" and cannot unlock the car. Another reports the driver's floor carpet sagging behind the pedals, and the replacement carpet had the same defect.

Reverse lights are too dim to light the area behind the car, so the backup camera image is nearly black at night. Where there are no streetlights, drivers say they can barely see past the rear bumper. Tapping the brake pedal adds a little light, but drivers cannot hold the brake while backing up. Owners describe this as a design weakness, not a part failure, and no fix is reported. One report places it at about 7,700 miles. Others say it has been present since the car was new.

This category mixes several problems. The most common is front axle clicking or grinding in turns. Repairs are stalled by backordered parts or dealer instructions not to replace axles. One lease car developed loud front suspension creaking at 3k miles, worst when accelerating and turning, and the dealer said Honda is investigating. Other reports describe "Service High Voltage System" warnings that cut power, stop the heat, and limit charging to about 25%. The main control screen can also go black and stay off.

Rear automatic braking can slam on while the car is barely moving in reverse with nothing behind it, and passengers think the car hit something. Some drivers turn the system off. The other reports describe a rear camera image so dark at night that objects are hard to see, starting at 10 and 600 miles. One dealer said the camera was working as designed. Another dealer did not diagnose the car.

One crash report describes the car surging forward at low speed while pulling into a parking spot and striking three parked vehicles. Collision mitigation braking did not activate, and the dealer could not explain the event. A second report describes a sudden total loss of power in highway traffic with no warning messages. The car could not go faster than 8 mph and would not restart for about 10 minutes. Both are rare in the filings but carry serious crash risk.

The car brakes hard with nothing ahead, at a stop sign or while driving through a green light, and nearly causes rear-end collisions. One owner says the false stops continued after a dealer software update. Another reports driver-assist systems shutting themselves off while one-pedal driving applies the brakes. The same owner describes traction control activating with cruise control set on dry roads, infotainment screens going black, and dealers unable to reproduce the problems.
