Brake Disc Caliper problems of the 2014 Mitsubishi Outlander

Right rear caliper rubs and sticks for a few days then stops after a few miles. It does not do it every day or every time I drive the vehicle. Does it more when it is below 40�. Continues to be an issue, cannot get parts to fix it anywhere including Mitsubishi. Called a dealer 2 weeks ago to order and still waiting for the part to come in.

On March 6, 2018 I was involved in a crash. I rear ended another vehicle in slow moving bumper to bumper traffic. When I hit the brake the car began to slide straight forward. No pulsation from the anti-lock brakes. I was and am very surprised that my car did not stop in time. In the interim I settled my claim with my insurance company. On 3/29/2018. On 3/30/2018 I received a letter from Mitsubishi telling me of an issue they call a "parking break" problem. I have asked several mechanics about the possible need to replace "the piston assembly of the rear brake caliper will be replaced with a countermeasure unit". I have bee assured this could have caused a failure to the anti-lock braking system. Because I no longer own the car I have notified allstate insurance of the present recall. If possible this should be an urgent recall. Sadly I have lost thousands of dollars and a record of 36 years of accident free driving. Please investigate.
