Six software bugs lurking inside a single module. That’s what Honda says is wrong with 65,135 Prologue and ZDX electric SUVs now under recall, every last one of them a 2024 model.
The defects live in the Radio Control Module, and when they fire, the instrument cluster and center infotainment screen can go completely dark while the vehicle is moving. No speedometer. No warning lights. No rearview camera image when you shift into reverse. Honda’s filing with NHTSA lays it out plainly: each of the six bugs can trigger independently, causing a processing error that either crashes the system or forces a restart.
The recall covers 45,562 Honda Prologues built between October 2023 and December 2024, plus 19,573 Acura ZDXs produced from December 2023 through January 2025. Both vehicles share the same Ultium-based platform, built alongside General Motors, and evidently share the same fragile display software.
Honda estimates only about one percent of the recalled population actually has the defect. As of mid-February, the company had logged 148 warranty claims. No crashes, no injuries — but a blank instrument panel at highway speed is the kind of thing that doesn’t need a body count to demand attention.
The intermittent nature of the failure makes it particularly nasty. Drivers may experience it once, restart the car, and never see it again — until they do, backing out of a driveway with no camera feed. Honda’s own safety risk assessment acknowledges the obvious: losing your speedometer and warning indicators reduces the driver’s situational awareness and increases the risk of a crash.
What’s notable is that this isn’t an over-the-air fix. Despite the problem being purely software, owners will need to haul their EVs to a dealership. Honda notified dealers on February 27 and plans to start mailing owners on April 20.
At the dealer, a technician will flash the Radio Control Module with updated code. No parts to replace, no hardware to swap — just a patch that apparently couldn’t be pushed remotely to vehicles that were sold as the technological future.
The Prologue has been one of Honda’s genuine bright spots in the EV transition. It arrived with competitive pricing, solid range, and the kind of packaging that made people forget it rode on GM bones. The ZDX gave Acura a credible electric entry.
Together they represented Honda’s entire battery-electric portfolio in the U.S. for the 2024 model year. Every single one ever built is now part of this recall.
That’s worth sitting with. Not a production subset. Not a specific build window flagged by supplier data. The entire run, from the first Prologue off the line in October 2023 to the last ZDX in January 2025.
Honda says the recall population reflects all possible vehicles that could experience the problem, which is a polite way of saying they can’t isolate which ones are actually at risk.
Owners who want to check whether their vehicle is included — and the math says it is if they own a 2024 Prologue or ZDX — can visit Honda’s or Acura’s recall websites or call 888-234-2138. The fix itself should be quick once the notices go out. The harder question is why a software defect affecting two screens required a physical dealer visit on vehicles engineered from the ground up as connected, software-defined machines.
