My 2012 Jeep Compass had same problem today! It broke off! I bought 7 years extended warranty, does it covered? thanks! Any one know?
I don't know about the extended warranty.... you may call to find out?
I just had the same issue with my 2012 Compass @ 48.800 miles when I noticed a rattling chain-like noise coming from underneath, finding a broken-off part sticking out from the engine protective shield scraping along the concrete driveway!
Dealership says it's not unheard of and happens quite often, warranty expired @ 36000 miles; labor cost will be around $130 +- plus part (FYI: tube part MOPAR 05273372AF - Tube costs ~$25 +- on Amazon, APSG CAP/COVER - Screw On Transmission filler seal cap is another $10 if you lost it).
No idea how long it actually has been broken off and laying on the shield until it found it's way into one of the ventilation slit.
I called the Chrysler assistance center: no recall, not heard of or logged in their system
(! - although you find same issue @ Jeep Patriot forum Dipstick Tube Breaking grrrrrr
Not only shouldn't the metal part just break by itself (IMHO it's a flawed design that snaps off at the bracket under normal engine vibration), it can cause fluid contamination etc..... another expense to get it exchanged!!
