I have a 2007 Jeep Compass (same car basically) and can confirm that the CVT has a dipstick tube with a plug on top. The label around the plug says “hands-off”, essentially. The owners manual says don’t touch it until 60,000 or 100,000 miles (can’t remember right now)
Somewhere between 35-40,000 miles I priced a fluid change through my trusted Indy transmission shop. As most of these cars were still under warranty he simply hadn’t worked on one yet. He researched what it would cost to do an exchange, just the cost of the fluid alone more than doubled his normal price. His advice? Don’t bother, the fluid in these sealed units really does last longer.
As an aside, a bearing inside the transmission started whirring a while ago. The dealer replaced it under warranty. I’m not sure that the bearing failure was related to not changing the fluid at 30,000 miles.
As an aside to my aside, the dealer sent me off down the road without tightening a brake line…
