Are there any quirks/known issues with the 5th years I should be aware of when searching for a used one?
Thanks
After owning Grand Cherokees for ten years, I have been very happy with my 4Runner. I now have put 46k miles on it and have had zero problems so far.
That being said, you ask about any quirks, I will say my biggest thing was getting used to the brakes. Not that there is any problem with them but they have something called "Brake Assist" that you should be aware of.
What it does is change the ratio of foot pressure required in what it perceives as a panic stop. In other words when you hit the pedal fast, even for a yellow stop light or unexpected slow traffic, it will increase braking force so that the vehicle really slows down fast.
This is an ongoing issue for me, I still do not like it, and I have gotten to where I will try not to apply brakes fast even when I probably should.
The reason is that I have removed the back seat bottoms and folded the back seat backs down flat and carry my work equipment and tools boxes in the back so when the brakes unexpectedly grab it throws stuff forward and makes a mess.
So the brake assist and the soft stock front shocks with the resulting nose dive is a minor issue or quirk to be aware of.
It does really stop fast in an emergency and could save your ass. (or get you rear ended by the car behind you)
Also if you change your own oil be aware that the procedure is a little more time consuming than what you may be used to due to having to remove a couple covers and skid plate as well as the fact that it has a canister style oil filter rather than the spin on kind.
Neither one of these things are a deal breaker, it is still an outstanding vehicle and I would buy another one if something happened to one I have. (Like getting rear ended due to brake assist kicking in)
