Re: brake pedal to the floor
Is the fluid level in the brake fluid reservoir going down? You notice any fluid drops or spills underneath where you park your Jeep? Crawl underneath it on a dry and sunny day and look for any dampness anywhere along any of the brake lines - there could be a hole in a hose; faulty bleeder screw; etc. Although the dealer should have inspected all that as part of the repairs they just did.
