Planned dealer dependence. There are plenty of vehicles still available with dipsticks, but many of the luxury manufacturers omit them so they can omit any warranty coverage if you run into issues and didn't do all of your service at the dealership.I could not believe the engine has no dipstick?? I always change the oil myself after the warranty period runs out and now it looks like I'm going to the dealer forever to get the oil changed!! Not happy with this option!!!
