Would glow plugs on a 3 year old Nissan Navara be covered under warranty/extended warranty ?? dealer says not but the timer would be, I have had other vehicles and never had a glow plug fail

I would have thought so, they aren't like Spark Plugs in a petrol engine. I once had 4 shock absorbers replaced on my Nissan Patrol at 145,000 under the extended warranty.

Ask the Nissan Customer relations team.

Greenant - If the warranty coverage is still valid, the only way Nissan can refuse to replace glow plugs, is if they are specifically excluded from the warranty, in writing.

Cheers, Ron.

Glow plugs fail!

The heat eventually kills them and the tips can break/fall off and drop down into the bore destroying the piston and possibly the head.
My Prado glow plugs are replaced whenever the injectors are out. They are not that expensive but the damage caused can be immense.

3 years gives no idea what work the engine has done. How many Km's? What sort of driving (as in what heat in the motor) etc etc
If you are having the injectors checked then have the plugs checked at the same time.
You need to have them checked by a real diesel specialist, not the local mechanic who has on experience on plug failures.

As to warranty - no idea but are the injectors covered for that age/mileage? If the injectors are then I would think the plugs are also.

For the price of them, just as easy to buy them and replace them yourself.
My view is that they are a wearing part, and as a generalisation, fall into the same categories as clutches, batteries, tyres etc.
