NHTSA Complaint #11640328 — 2017 HONDA CR-V

Vehicle unexpectedly begins to start flashing all warning systems while simultaneously losing excessive power. Unexpected ADAS system malfunction may cause the vehicle to break unexpectedly creating unsafe conditions or driving hazards for driver, passengers and others on the road. There is a significant loss of power, again, creating dangerous conditions while driving through busy traffic at high speeds or driving uphill. - Hill Start Assist Problem - Adaptive Cruise Control - Collision Mitigation System - Road Departure Mitigation System - Electric Parking Brake - Tire Pressure Monitor - Emissions system - All Wheel Drive - Brake System Problem - Brake Hold - Power Steering System - Vehicle Stability Assist Attempts to resolve issue Attempt # 1: Honda did a software update, resolved the issue for about four-five months (December 2020).... Mileage 49,504 # 2: Replaced Battery and Spark Plugs (April 2021) # 3: Appointment Scheduled for May 12th, 2021.... Mileage 54,330 #4: Disconnected battery mileage 96,000+ #5: New Spark plugs and new battery mileage 97,000+ The first time this occurred I was driving with my wife and two children. We were traveling down hill, a narrow road which is steep and has any sharp turns. As the system failures began to light up the car became extremely unsafe. There was very little control of the brake system as well as the steering system. Fortunately we avoided a potentially deadly scenario. Once we came to to level terrain where we could eventually slow down enough to stop the car, it was shuttering the whole way until we found a safe spot to pull over nearby. The car was then towed and serviced by Honda of Ithaca (Ithaca, NY). That same dealer said the resolved the issue with confidence, that it just needed a software upgrade. The concern here is that there seems to be no resolution for this issue and no warning as to when this could and seems to be will happen again.
