C.A.R.S. Protection Plus Refused to honor claim - adjustor told repair show design flaw. customer service says no prior repair not done properly Murrysville Pennsylvania

Purchased used vehicle and purchased 3 year service protection.  First claim for a tow C.A.R.S. did not have a policy

for me - claimed denied, claimed dealership did not send in the money.  Second claim do not cover clutch repair - claim denied .  Third claim adjustor told the repair shop it was a design flaw.  I checked with Mitsubishi to see if there was a recall - no recall.  Called Customer Service, Diane told me no the report says apparently there was a previous repair and they (C.A.R.S.) decided the repair wasn't done properly.  I believe corporate decided "design flaw" may be a possible lawsuit.
