What's wrong?
The recalled 2010 Lexus Hs and Prius use an antilock brake control module to manage braking when a wheel starts to slip. That module reads wheel-speed information and adjusts brake pressure so the vehicle keeps braking while reducing wheel lockup on rough or slick pavement.
In NHTSA campaign 10V039, the problem appears after ABS activation during slow, steady brake application. After the system intervenes, the pedal feel can become inconsistent, so the vehicle does not slow as much as the driver expects for the same pedal pressure. The result is longer stopping distance than the driver planned for in that moment.
There is no warning sign before failure. What owners notice is the brake feel changing after ABS activation, especially on rough or slick roads during steady braking.
Who's affected?
Covers Hs and Prius cars from the 2010 model year, both tied to the same anti-lock brake system (ABS) component.

What's the safety risk?
NHTSA campaign 10V039 describes ABS control-unit programming that lengthens stopping distance beyond what the driver expects, increasing crash risk. Leave more room to stop, slow down earlier, and schedule the recall repair soon. Repair will be free at any franchised Lexus dealer once available.
What should I do?
- Check your VIN to confirm your 2010 Hs or Prius is included in this recall.
- Contact a franchised Lexus dealer and ask whether the ABS control unit programming repair is open for your VIN.
- Reference recall number 10V039 when you call the dealer.
- Bring the recall notice if you have it, or bring your registration so the dealer can confirm the VIN.
- Drive with extra following distance until the repair is complete because the brake feel concern can increase stopping distance on rough or slick roads.
What happens at the repair
Lexus listed the dealer repair as an ABS control unit software rewrite. The safety recall began on March 3, 2010, with completion expected in late March 2010. If your VIN is included and the dealer confirms the campaign is still open on your vehicle, a Lexus technician rewrites the ABS control unit programming. The final dealer repair is free once available for your vehicle, with parts and labor covered by the recall.
