Ignition shift interlock. Closed oct 14, 2010, led to recall 10V-364.

NHTSA summary
On August 4, 2010, American Honda Motor Co. (Honda) submitted a Defect Information Report (DIR) to NHTSA regarding a ignition interlock defect in approximately 384,220 model year (MY) 2003 Honda Accord and Civic and MY 2003 and 2004 Honda Element vehicles with automatic transmissions (Recall 10V-364).In a September 22, 2010 supplemental DIR, Honda expanded the scope of the recall population based on manufacturing and complaint data.The total population for the complete recall is approximately 551,498 vehicles.The information listed in this closing report refers only to the subject vehicles, MY 2003 Accords with automatic transmissions.According to Honda's DIR, Under certain conditions the interlock lever of the ignition switch may unexpectedly deform, which can allow the interlock function of a vehicle with an automatic transmission to be defeated if the driver does not follow the typical shut-down procedure of shifting the gear selector to the Park position before rotating the ignition key to the off position. Removal of the ignition key when the gear selector of a vehicle with an automatic transmission has not been shifted to the Park position can allow the vehicle to roll away, increasing the risk of a crash.Honda's dealers will be instructed to inspect the ignition interlock switch and, if necessary, replace the original interlock pin and lever within the ignition switch and replace them with new, redesigned parts.This investigation is closed.

What owners wrote

“While trying to accelerate the car loses power. This has happened many times. The Honda dealership has said the system is on back order and they will call me when it’s available. It’s been months. The “jerks”a few times then the check engine light comes on then the car loses power. The dashboard lights are brake system, emission system, electric power steering, hill assist and ACC system problem.”

Filed Sep 8, 2025

“Three times, while driving, the car went into limp mode and would not accelerate. Had to pull over, turn car off, and back on to fix the issue. Have had it looked at and they have mentioned engine coils and a new control module. Had it at the dealership in January and they did their full inspection and to fix fuel pump recall and didn’t mention any issues regarding this.”

Filed Mar 4, 2025

“All the warning lights turn on and the car loses power when accelerating. It shows the check engine code P0301. The spark plug and coil are fine. Potential issue is the fuel injector leaking.”

Should you keep driving it?

This page can't tell you that. 1 of 40 reports involved a crash and 1 people were hurt. 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.
