My engine, like a lot of G35s, has rapidly been consuming oil. Note I have a 2005 G35 Sedan 6MT. Last week it completely seized up on the highway and I had to it towed to Infiniti since it is still under warranty. They said the engine is locked up and are requesting a teardown that I pay of $459. Infiniti (not the dealer) wants pictures of valve covers and pick up tube to ensure it wasn't due to sludge buildup. They said sludge build up will cause it to not be covered under warranty. Has anyone had these issues when you had this happen? What do I do??? Anything I should state to them? They are waiting on my decision for the tear down.

Thanks for all help

 

If you werent running enough oil, your engine seized. My car has severe oil consumtption but as long as you keep an eye on the oil level and top it off when needed, your motor should not seize.

 

Sludge build up results from the lack of oil changes, which Infiniti can use to void your warranty. For the engine to seize there must have been very little oil in it. Did you have the oil changed at the dealer; or have any paperwork proving that you conducted oil changes at normal intervals?

 

Not all oil changes were at the deal, but all were at regular intervals with full synthetic oil.
