“The contact owns a 2023 Lexus NX 250. The contact stated that while driving at various highway speeds, the vehicle suddenly decelerated.

The manufacturer was not yet contacted. The failure mileage was 14,000.”
NHTSA complaint #11755435, filed 2026-08, 14,000 miles“Vehicle is built so that water from hand-washing/rinsing gets under the hood and into a computer causing electrical issues and causing the car to not start. The dealership put a foam/rubber trim around the hood to prevent water from getting in but this won't last forever and, when they tested the other cars of the same model on the lot, they confirmed it happened with those cars also. The manufacturer's statement was that the owner's manual says you are not supposed to hand wash it. This is ridiculous. The owner's manual says you can't pressure wash the engine compartment - which noone did. …”
