NHTSA Complaint #11554586 — 2018 JEEP CHEROKEE

In the beginning of July, the parking brake engaged on its own and a warning came up on the dash. It took some jockying to get the brake to disengage but it continued to happen. We took it to the dealer where purchased who told us that the parking brake control module was damaged by water and that bedause of this the extended warranty that we purchased for a few thousand dollars would not cover it (even though we were told it covered everything). The dealer wanted $2000 to fix it. I took the Jeep to a qualified mechanic whom I deal with, and he replaced the the control unit. We picked up the car and a week or so later the brake came on again. We took it back to the mechanic who dug deeper and found out that the body of the car was leaking, and water had run down and into the control unit again. It is now November (going on five months!) and we still do not have the car back because he is waiting for the part to come in. I'm a pretty patient person but this is ridiculous. I'm paying for a car that I haven't had for five months and then I'm told this is a common issue with Jeeps and no warranty will cover it. I sincerely beleive this should be arecall issue by Jeep. Especially when they cannot get me a part to fix it for months! Any help you can render is much appreciated. Thanks
