All 4 Known Issues
Both the instrument cluster and infotainment display can suddenly go blank while driving, eliminating the speedometer, navigation, climate controls, and safety warnings. The defect is in the Radio Control Module software, which manages communication between the vehicle's display systems and other electronic components. Honda issued a safety recall in early 2026 affecting approximately 65,000 Prologue and Acura ZDX vehicles. The failure may occur intermittently and sometimes resolves temporarily after restarting the vehicle, but loss of the driver display while driving is a significant safety concern since the Prologue has no physical instrument gauges.
Common Symptoms
- Both instrument panel and center screen go completely black
- Speedometer and driver information display disappear
- Climate controls become inaccessible (screen-only controls)
- Backup camera stops working
- Displays may flicker before going blank
How to Fix
Contact a Honda dealer immediately to have the recall software update installed at no cost. Owner notification letters are expected to be mailed beginning April 2026. If the screens go blank while driving, pull over safely — you have no speedometer or warning indicators. Restarting the vehicle (turning off and on) may temporarily restore the displays. Do not rely on the restart as a permanent fix. Check NHTSA.gov/recalls with your VIN to confirm recall eligibility.

- TipIf the screens go blank while driving, safely pull over and turn the vehicle fully off (foot off the brake, press power button). Wait 30 seconds and restart. This usually restores the displays temporarily until the recall software update is applied.
The 2024 Honda Prologue can experience high-voltage electrical system failures that disable DC fast charging, limit acceleration, or disable climate control. The 'Service High Voltage System' warning appears on the dashboard, sometimes accompanied by a sudden loss of heating or cooling. The Prologue uses GM's Ultium battery platform, and the issue may involve the battery conditioning system, onboard charger module, or high-voltage junction box. Some vehicles have been rendered inoperable, requiring tow to the dealer. The issue is distinct from the display blackout recall and affects the vehicle's powertrain and charging capability.
Common Symptoms
- Service High Voltage System warning on dashboard
- Vehicle unable to DC fast charge
- Sudden loss of heating or air conditioning
- Reduced acceleration or power limitation mode
- Vehicle will not start or enter Ready mode
How to Fix
If the Service High Voltage System warning appears, safely reduce speed and drive to the nearest Honda dealer if the vehicle is still drivable. Do not attempt to charge the vehicle until the warning has been diagnosed. The dealer will need to perform high-voltage system diagnostics, which may involve replacing the onboard charger module, battery conditioning system components, or updating software. Repairs are covered under the 8-year/100,000-mile EV powertrain warranty. If the vehicle is not drivable, request a flatbed tow (not a conventional tow) to protect the electric drive system.

- TipKeep a record of every Service High Voltage System warning occurrence with photos. If the issue happens more than twice, this documentation supports your case under state lemon law protections and the federal Magnuson-Moss Warranty Act.
The 2024 Honda Prologue's automatic emergency braking (AEB) system activates unexpectedly with no obstacle or vehicle ahead, causing sudden hard braking that risks rear-end collisions. The issue is part of a broader NHTSA investigation into Honda's Collision Mitigation Braking System across multiple models. False activations occur most frequently when reversing, at low speeds in parking lots, and occasionally at highway speeds. The Prologue shares its Ultium platform with GM but uses Honda's own ADAS sensor stack, which appears to have calibration issues. NHTSA has received reports of the AEB activating at approximately 70 mph with no visible threat.
Common Symptoms
- Vehicle brakes hard suddenly with no obstacle ahead
- AEB activation warning appears on dashboard unexpectedly
- Phantom braking while reversing in a clear parking lot
- Sudden deceleration on the highway in clear conditions
- Collision Mitigation Braking System alert without any obstruction
How to Fix
Visit a Honda dealer to ensure the latest ADAS software calibration is installed. If phantom braking has occurred, report it to NHTSA.gov with as much detail as possible (speed, location, conditions). There is currently no official recall, but Honda is aware of the issue as part of a broader AEB investigation. Some owners have found that the forward collision warning sensitivity setting (adjustable in the settings menu) can reduce false activations when set to 'Far' instead of 'Normal.' Do not disable AEB entirely as it provides genuine safety benefits.

- TipSet the forward collision warning sensitivity to 'Far' in the vehicle settings. While counterintuitive, this setting reportedly reduces false AEB activations by giving the system more reaction time to confirm a real obstacle before braking.
The 2024 Honda Prologue has a widespread defect causing loud clicking or knocking sounds from the front axle area, especially when making turns or accelerating from a stop. With 98 NHTSA complaints filed at an average of just 24 miles, many owners report the noise appearing within weeks of delivery. The CV joint boots or inner joint assemblies appear to be defective from the factory. Honda issued a Tech Line Summary Article on December 19, 2025, acknowledging the 'clicking or ratcheting type noise when turning' but directed dealers not to attempt repairs if no visible damage is found. Replacement axle parts have been backordered nationwide due to the volume of affected vehicles.
Common Symptoms
- Loud clicking or knocking when turning at low speed
- Ratcheting noise during acceleration from a stop
- Noise is louder when turning the steering wheel fully left or right
- Clicking increases with vehicle speed during turns
- Noise may come from either front wheel area
How to Fix
Document the clicking noise with video recordings and file a complaint at NHTSA.gov to support potential recall action. Visit a Honda dealer and reference the December 2025 Tech Line Summary Article for the Prologue CV axle noise. If the clicking is severe, request axle replacement under warranty — though parts may be backordered. The noise itself is not a safety hazard per Honda's assessment, but the axles should be inspected for CV boot tears or grease leakage. Consider filing a lemon law claim if the noise is not resolved after multiple dealer visits.

Parts and tips from 98+ owners who fixed this issue
- TipRecord video of the clicking noise with your phone and include it with your NHTSA complaint. The more documented complaints, the faster NHTSA will escalate to a formal recall investigation. Also ask the dealer to note the issue in your service record even if they say no fix is available.
- TipHonda has confirmed the clicking is not a safety issue and the axles are safe to drive on. Do not pay out-of-pocket for axle replacement — this should be covered under the factory warranty.
