NHTSA Complaint #11490049 — 2016 HONDA PILOT

My 2016 Honda Pilot has been experiencing an issue with the auto start-stop system, in which the vehicle's engine fails to restart after a stop and/or the dashboard indicators flash on and off with multiple error codes displaying. This has happened many times on the highway and on streets, one time where it would not restart on the highway and cars were going around me on both sides which was very dangerous. I reported this to Honda corporate and opened up a case, which was open for many months while the Pauly Honda dealer in Libertyville, IL and the Muller Honda dealer in Gurnee, IL tried to diagnose the problem. They ended up trying several fixes, including replacing the battery, but nothing has fixed the issue. The dealer also contacted the engineers at Honda Corporate, and they indicated that they were not aware of the issue and have not been able to provide any fixes. This is still an issue today, and the only workaround I have is to disable the auto start/stop function manually, every time I start the car. Dates: - I checked and we actually brought our car into Muller Honda of Gurnee in September 2021 where we reported an issue where "C/S (customer) feels like it wants to die coming to a stop. Dash lights turn off like vehicle died. All displays go dark." They felt that it was "Caused by: Technician verified keyless remote system problem light on dash. Tech found code B12C5 stored in system. Corrected by (Y9300) (6S100) Warranty extension. Keyless start system error with DTC B12C5. BulletinS". This did not fully resolve the issue. - Then in October 2021 we brought the car into Pauly Honda of Libertyville where we again reported the same issue where "Customer states in eco mode the center screen now goes blank then cycles and comes back on." This did not fully resolve the issue. - Then in the spring of 2022 we brought it back to Pauly Honda as more severe issues started occurring. I also opened up Case #13103604 with Honda Corporate.
