I'm late to this party, but I need to join so others(and jeep) know this is a bigger issue than Jeep acts like it is.
I am the original/only owner of my 2015 Patriot, 4WD. I complained for YEARs about how rough it idled at stops in drive. Jeep mechanics insisted many things like: spark plugs, oil changes, type of oil, type of gas, and eventually just resorted to gas lighting me "it's normal", "it's supposed to be like that". I'm typically talked down to when it comes to issues with my Jeep. I fix as much as I can myself and I actually know quite a bit about my Jeep. It is not normal for any car to shake so bad it makes you feel like you're in a bad carnival ride.
3 weeks ago I went through hell with this car and as many of you know these cars tend to have problems that won't throw codes even though they should. Serpentine belt wore out and the whole dash was lit like a ******* Christmas tree. I had so many codes, finally, I thought my days of being shaken were going to be over. I replaced: spark plugs, ignition coils, air filter, serpentine belt, tensioner do-dad, and a couple other things. I've just recently done an oil change and fuel injector cleaner. It runs SO rough now it's insane, but everything else is amazing. No more mysterious misfires that mechanics insist are not happening (ignition coil, 1st cylinder, so easy). I've been doing the trick with neutral so I don't have panic attacks every time I have to drive.
Motor mounts need to be replaced badly and I don't have the equipment to do it myself and JEEP should have stuck to their contract and OWNED their mistake and just fixed the mounts while I was in warranty. I haven't even hit 100,000 miles yet and it's just wrong that this isn't covered when they KNOW they screwed up. I love my Jeep. It's like it was made for me. I shouldn't be responsible for other people's mistakes, especially financially. I have to save up money and pay some stranger to work on my baby and odds are they will break something or mess with something they aren't supposed to. It's estimated over $1,000 right now. I'm just so angry.
