When our 200 Series 2007 Toyota Landcruiser VX went in for a 180,000 km service it was discovered that the compression was down in three cylinders and the vehicle requires a rebuild. The apparent cause was dust. This vehicle has never been off road and sees very little dust and is sold under the banner of "king off the road" anyway, so a bit of dust should not be a problem. Toyota has offered to pay 50 percent of parts only. As this appears to be not uncommon, going by web forums, does Toyota have a case to answer and should they cover more of the cost to fix? Quote is $25,000.
The offer that Toyota has made is a pretty standard one across the industry, one that's generally determined by the age of the vehicle. In this case the car is seven years old and has done 180,000 km, so it would be a stretch to say you had a claim for the whole cost of the rebuild. The question is how much Toyota should contribute and that's hard to answer. Half of the cost of the parts I would think isn't enough; I would say that the bill should be split down the middle.
