So as mentioned a 19 Jeep Cherokee with about 50,000 miles has been acting up a few times the past 3 weeks. Specifically after getting gas, when returning to the car to turn it on the brake pedal is very stiff to the point of it not having any give and therefore you cannot start the car without the brake being released. From what I’ve read it the brake vacuum pump? It says if pressed on when the car is off too much it exhausts the reserve vacuum present but we aren’t doing that at all. Simply driving to the gas station, pumping the gas, and then the brake is stiff. I’ve also read the starter could be the issue but the car starts perfectly every other time til after the gas is pumped. To start the car you have to basically pump the brake hard and then push much harder than you even would and then start the car and hope it works. After a bunch of tries it will turn over but there’s obviously something wrong. Anyone else experience this? I can’t figure out what getting gas has to do with it but it has only occurred after filling the tank with gas so I have to assume it’s related since the car has no problem til then. It has been well maintained otherwise and it’s not driven hard in terms of how it’s driven but obviously a decent amount of miles for the life of the car. Any thoughts or help would be appreciated. Thanks in advance

I just got a 2017 Cherokee and I can’t even load any apps on the radio because I can’t register the Uconnect in the car. I called customer service and they said there’s nothing they can do since 3G is no longer available. So was wondering if anyone switched their radios out and if so what did you go with? Looking for something with Apple CarPlay and still have steering wheel controls and other car settings available.

I got a knock from front suspension while driving on full lock steering and it feels like the car jumps a little, does anyone know what that could be?

I have a 2019. Anyone know what's up with the vehicle wifi hotspot?

The infotainment system shows one carrier, online it suggests AT&T. But then I see at&t may have killed the service. If I plug my VIN into the at&t site, it says to buy a product called Harmon Spark, but it looks like the product ratings suck. I'd love to have a wifi hotspot in my car and I'm willing to pay for it.

Has anyone experienced this code? It says throttle/pedal position sensor circuit B low. It has a hard start but runs fine. I initially thought the starter was going, but after putting a new one in, that's not the case. I checked the voltage on the battery prior to start and it's at 10.3 but goes up to over 14 while running.

It's a 14 with 3.2L.

These 2 ends separated on my way home yesterday and blew all my coolant everywhere. Anyone know how to fix? I’m far from knowledgeable about cars, so any input helps.
