Dead battery on other Pilot years
Report counts are for each model year on its own, so a newer car has had less time to collect them. Model years with too few reports of it for a sheet: 2014, 2015, 2018, 2022, 2023, 2024, 2025, 2026.
What this problem usually is
These owners walk out to a car that's dead. Some find it drained after sitting only a day or two, some need a jump start every week, and some have had the battery replaced more than once without the problem going away. A good number describe the dealer testing the battery, calling it fine, and sending them home.
What got replaced
Owners who name the part that was replaced mention the battery (26 reports), the starter (5 reports) and the alternator (3 reports).
Recalls and investigations
One recall on the electrical system covers the 2021 model year. A recall on the same system isn't always the same failure, so read the defect text.
Incorrect central network software programming may cause several errors to occur that can delay or prevent the rearview camera image from displaying.

Too few of these reports state a mileage to give a range.
What owners wrote
“The vehicle has routinely had issues restarting from auto idle. When the vehicle turns off in traffic at a stop or stopped at a red light, then it will not restart and the vehicle will essentially be dead for several minutes and unable to be turned on or moved.”

“Car does not want to start even though the batter and alternator are good (tested by tow truck company). Restarts fine once batter is disconnected and then reconnected again. This has now happened twice.”

“While stopped at an intersection, the car died, the transmission shifted to neutral automatically and the radio would not turn on. The AGM battery was replaced approximately one year ago when a similar situation took place.”
Filed Dec 18, 2025
“Car is slow to start or doesn't start at all, particularly after frequent engine stops/starts or when engine has idled for a period of time. Battery has been replaced. Symptom comes and goes, but seems to get worse with frequent engine stops/starts (i.e., driving to different locations with short stays at each, or with the automatic engine shut off)”

Should you keep driving it?
This page can't tell you that. 0 of 31 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
File your own report with NHTSA. Complaint counts are how a problem gets an investigation. How reports land on this sheet.
