Hi when I'm driving my accord the immobiliser light comes on and the engine stops. By switching it on and off a few times it starts and it's ok for about three weeks then it does it again . Any ideas guys.

 

Moved to correct forum. Welcome to HAF.

Watch for Check Engine and Alternator lights when engine stops. If these lights are not coming on, the keyswitch assy probably has failed.

Alternatively, the key may be defective. This seems more likely but others will have to provide help as I'm not familiar w/ the immobilizer system on these accords.

good luck

 

Use another key in the car to see if you still have the same problem.
