NHTSA Complaint #11618247 — 2025 HONDA PILOT

New 2025 Pilot with about 3,000 miles, driving in Montana on a level dusty gravel road at about 5,000 feet altitude. Driving into the morning sun for about 20 minutes at a slow speed of about 30 mph all of a sudden multiple warnings flashed, engine, brakes, etc. Steering was stiff and brakes did not feel active, very stiff. I just coasted to a stop on a desolate gravel road, no other traffic. The engine was still running, did not press on the gas for in large red letters the warning panel said "DO NOT DRIVE". The car was very dusty. If we had been on an Interstate at 70 mph that would have been an accident, with steering and brakes inhibited somehow? I shut OFF the engine, waited 10 minutes, started engine again and WARNINGS still active. Shut OFF engine and waited 20 minutes. Restarted engine and looked like warning were starting to clear, and steering and brakes felt normal again. With no WARNINGS showing I drove very slowly for many miles with no further occurrences. Slowly worked my way back across the country to Florida without any further failures. It appears to all be computer related, perhaps sensors failing and the computer shutting down what must be electrical steering and brake assist. At speeds with Interstate traffic, that condition will be an accident. There are no failure codes shown on the access panel. We have an appointment with our Honda service dealer, maybe they will be able to access a computer history to see the failure mode that caused loss of steering and brakes. The fact that a computer can impact those critical systems on a vehicle, is a serious safety issue. Prior to this incident, driving about 30 minutes on a dusty gravel road in Montana, some sensor must have been actuating the rear brake caliper, I could hear the scraping sound of pad on rotor, didn't sense the car slowing. The car was dusty, maybe sensors inhibited, the scraping lasted about 15 minutes, at least that it could be heard in the car. Could be a safety iss
