NHTSA Complaint #11542487 — 2023 HONDA PILOT

Honda Pilot 2023 Elite shows 15+ error messages on the instrument panel. Messages indicate emissions systems, breaking systems, power steering and various risk mitigation systems experiencing problems resulting in reduced performance. Errors show up when the vehicle starts and are easy to reproduce. Dealer has looked at the vehicle 3 separate times. Problem occurs again in few days after dealer visit. Dealer based on the system error code diagnosed the problem with the fuel system. So far the dealer has replaced the high pressure fuel pump, injector relay, fuel pressure regulator and fuel rail pressure sensor. Dealer says when the vehicle starts the problem with the fuel system causes the electrical/computer system to go in safety mode; this makes onboard computers believe all systems are failing. Dealers' attempts (in consultation with manufacturer support) have so far not resulted in successful resolution of the problem. Without taking undue risk, I have personally tested some of the safety systems in errors indicated on the cluster panel to actually not work, e.g. lane departure mitigation system. Importantly, it feels vehicles braking distance has increased and steering is harder compared to when vehicles had no issues. All errors that are displayed are listed below. 1. Emission system problem, 2. Break system problem, 3. Electric parking brake system problem, 4. Break hold system problem, 5. Electric power steering problem, 6. Trailer stability problem, 7. Adaptive cruise control system problem, 8. Road departure mitigation system problem, 9. Vehicle stability assist system problem, 10. Hill start assist problem, 11. Trailer stability assist problem, 12. Hill descent control system problem, 13. Collision mitigation breaking system problem, 14. Road departure mitigation system problem, 15. Low speed breaking control problem.
