So I just had my brakes replaced by my local dealer after I purchased my used 2014 JGC Laredo. They replaced rotors, and calipers as they were bad before purchase.
So here's my problem...after the replacement I drove to work, and basically had no brakes...my brake light had turned on and it was extremely difficult to stop (I ended up driving in sport mode and just downshifted to slow down enough, kinda scary!) After I got to work I popped the hood thinking I was out of brake fluid but the levels were fine. I was told by a mechanic friend it could've been air in the lines that caused it. After sitting I drove home, brakes were fine and it hasn't happened since...my question is, is this a common problem? I read something about bad brake boosters which sounded similar, the pedal was hard to push felt like a lot of pressure. I was almost thinking that maybe I turned the vehicle off before putting it in park? I have done that before being new to push button so I'm still getting used to it. Just looking for opinions and seeing if anyone has had a problem like this. When the problem was happening I got a message saying "Service Electronic Braking System" but as I said the brakes have been find since this one instance and the code is no longer popping up?
