Thread: Is warranty void ?

I assume that in legal argument all warranty questions would come down to the question: did the actions undertaken affect the performance of the parts (now failing).
Changing the oil (with the correct spec) could hardly meet the above. (IMHO)
No doubt though, should a gearbox, under 3 years /100,000kms, had the oil changed, and then fail...that Landrover would probably deny warranty claim; and the lawyers would try to get rich.
I think the chances of all of the above ever happening would be quite remote though ;-)
I changed my oil and pan at 50k kms. It was out of warranty, at the time.

Don't tell them.
Probably wouldn't notice.

Legally, hes wrong But only if the oil change is done IAW the landrover procedures at a suitably qualified mechanics.

you doing it or you swapping a part or paying a mechanic to swap a part that is not OEM can void your warranty.
