NHTSA Complaint #11614299 — 2018 HONDA ACCORD

My 2018 Honda According Touring 1.5 Liter Turbo has an intermittent problem with the vehicle’s warning alerts. The vehicle systems affected include Adaptive Cruise Control, Vehicle Emission System, Tire Pressure Monitoring System, Vehicle Stability Assistance, Hill Start Assist, Braking System, Road Departure Mitigation, Blind Spot Info System, and Collision Mitigation System. When I checked online for other 2018 Accords with a similar problem and found numerous cases. The most commonly recommended corrective action was to replace the battery. I tried that. It corrected the problem for two months, but the same multiple systems failure displays have occurred again. Interestingly, none of the systems that could be independently checked (e.g., brakes and TPMS) showed any indication of actually malfunctioning. There are multiple cases online, reported by 2018 Accord owners, of receiving different explanations from Honda dealers as to the cause of the malfunction from rodent damage to problems with the turbocharger. Several people reported paying for repairs that did not correct the problem or did so only temporarily.
