I have a 2004 Toyota highlander leaking oil, oil light comes on. Could it be the rubber rings?

check your universal joints on the driveshaft as they will cause a bad vibration while driving

check trans mounts

What code did you have?

Well, let me just say that if you have gone 10,000 miles without servicing your brand-new Lexus, you are a LOT braver than I would ever be. I certainly do not have the gold available to pay for the possible consequeces of pulling that one off. When was the last time you even checked your engine oil level? I have seen MANY vehicles run completely out of oil between 3000 mile services and completely DESTROY the engines! 10,000 miles is REALLY taking HUGE chances!

You may have 2 separate problems...One for the oil needing service and one for a problem with your AWD system. However, Toyota and Lexus are known for disabling things like AWD, ABS, Traction Control, etc. when the engine computer detects things like low oil pressure or low oil levels. This can cause several warning lamps to all come on at the same time.

GET YOUR VEHICLE SERVICED!!! Hopefully, you will be one of the lucky ones and have not done any serious damage by not getting it serviced when you should have.

Your oil should be changed every 3000 miles (Or every 5000 miles if you are using full-synthetic oil). You should also check the oil level between services AT LEAST every 1000 miles (or more often, if you are having to add oil at 1000 miles). For a properly maintained vehicle, checking the oil level between oil changes SHOULD seem a total waste of time. However, it is the single, MOST IMPORTANT thing you can spend your time on when it comes to getting a lot of miles from your investment. If your engine starts using (burning) oil or if it starts leaking oil, you will not know about it in time to save your engine if you are not in the habit of checking it on a regular basis.

i would go to nearest parts store and ask them to do an obd2 scan. oreillys, advance auto, and auto zone i know do it for free.

not much change oil and filters and rotate tires and small inspection on car

check to make sure you don't have a vacuum leak to the cruise system. sounds like it is loosing vacuum and taking a while to build up.

You need to talk to a dealer.

If you are using that much oil you either have a BIG leak or your BURNING oil through bad rings

It sounds like your heater core is leaking. Check to see if you are losing coolant, are smell like antifreeze???? With 190,000-miles this could be what your smelling??? Just a though???
