Just and FYI....I just received a letter from FCA indicating they are extending the warranty on the power brake booster in my 2011 DD Crew to unlimited mileage and 10 years. It says this is not a recall (seems like we had a recall earlier for brake booster), but goes on to state that some vehicles may experience a vacuum leak resulting in "higher than normal brake pedal efforts". They sent a form to submit if anyone has paid for this repair out of pocket so reimbursement of expenses can happen. Your claim will happen within 60 days of receipt per the letter. This applies to certain 2011-2014 Dodge Durangos and Jeep Grand Cherokees.
