2018 Honda Accord electrical system problems

“The car hesitates upon acceleration and when it “misses” enough it will flash the engine on the dashboard, and not allow any further acceleration, going into “limp mode”. All the safety controls error on the message center and dashboard warnings all come on, even though it’s only the acceleration/transmission that’s affected. Not sure if it’s fuel injectors or a computer issue, but it’s absolutely dangerous upon entering a highway and hoping to not have system failures, that result in limp mode. I’ve been carrying a 10 mm socket for disconnecting the battery and rebooting the system, when needed. It only helps for a short while.”

“Reporting fraudulent safety recall compliance & hazardous repair by Honda of Manhasset (Invoice #317524). 1. Recall 23V-858 (Fuel Pump): Dealership registered recall as completed & Service Manager verbally insisted it was done. However, my vehicle's continuous dashcam footage proves fuel pump replacement was NEVER performed. Faced with video evidence, the advisor admitted work wasn't done because the part was out of stock, claiming a "billing error." Invoice reprint says "RECALL NOT PERFORMED, PART NOT IN STOCK" yet they initially processed it, leaving an immediate engine stall risk. 2. Software Campaign & Radar Failure (Service Bulletin 21-068): Dealership performed mandatory Honda Sensing update for Millimeter Wave Radar, wiping old calibration parameters. Per Bulletin 21-068 (Pg 3), the repair is NOT complete until the radar is re-calibrated & the warning light disappears. Instead of performing the radar aiming, the technician left safety systems locked with DTC P2583-76. I authorized a $215 diagnostic fee, but despite having the scanner connected during the update, the technician failed to follow Honda's official troubleshooting protocol to resolve the code…”

“2018 Honda Accord repeated battery drain/electrical failure My 2018 Honda Accord has a recurring electrical problem. The vehicle’s battery is approximately one year old, but it has died six times within the last four weeks. Each time, the battery becomes completely discharged when the vehicle is parked and not driven for several days. A battery test dated XXX, reported: “BAD & REPLACE,” battery health 16%, state of charge 0%, voltage 4.61 V, and measured capacity 106 CCA compared with a rated capacity of 600 CCA. The repeated failures suggest a possible parasitic electrical drain or electronic module that does not shut down when the vehicle is parked. This condition can leave the vehicle stranded and may prevent starting in an unsafe location or emergency. I request that NHTSA investigate whether this is a recurring safety defect affecting 2018 Honda Accords VIN [XXX] Millage 143,000”

“Dashboard lights are coming on for all systems...sometimes they go off but then come back on 2/3 days later. The lights and messages are: collison mitigation braking problem, road departure mitigation system problem, emission system problems avoid heavy acceleration and high speed, tire pressure monitoring system problem, brake system problem brake performance may be reduced, electric power steering system problems steering assist reduced , vehicle stability assist system problem, reduced traction and handling. Concerned about my safety.”

“The contact owns a 2018 Honda Accord. The contact stated that while starting the vehicle, several unknown warning lights unexpectedly illuminated on the instrument panel. The failure mileage was approximately 116,242.”

“My car keeps losing power suddenly! Sometimes it has even started to stall while driving. Also the electrical menu has tons of errors and isn't working. There are several recalls on Honda Accords for the fuel pump and the vehicle assistance module but my vin doesn't show up.”
