Jeep was having brake problems. Replaced all the brakes this spring and still having a problem. Took the Jeep in to the dealer in June to have the brake booster looked at, said it was fine. Since then the brakes have been getting worse. Today I crashed into the front of my house. There is something wrong with the brake booster, like I told Jeep back in June. This same thing is happening on many other Jeep. Please something has to be done. The dealership is saying they looked at the "splash sheild" under the recall and since nothing was wrong they are not responsible for anything else on the booster. Please read other Jeep owners having the same problem. Https://jeepgarage.org/F73/more-brake-booster-intrigue-186178.html#/topics/186178"page=3. I took the master cylinder off and there is a bunch of rust inside the booster. It's a closed system, debris shouldn't be building up or rust shouldn't be getting in there. Maybe this was caused from the splash shield and water got inside"

When slowing the vehicle it will just silently shuts off. This happens usually at the same 5 places, 3 of them when slowing to make a right hand turn in an S turn and the other 2 going straight slowing to stop to make a left turn across traffic. I feel like it's a combination of braking, steering wheel and when its shifting into 1st since I'm either in a stopping situation or S turn situation. When this happens I loose steering and brakes causing me to go into the opposite lane of travel head on. There have been recalls on the alternator for my vehicle but mine has never been included. There has been a recall for a sensor that has been completed but did not solve the problem. This is a serious issue, my chance for a head on collision is very very scary. This happens about 6-10 times a week.

4 times in the last 3 weeks, the last time just today, as I was decelerating and turning right while getting off highways onto exit ramps, the steering wheel felt like it locked - the power steering turned off, as did the power brakes - I had to coast, and the rpms showed 0, although all the lights were still on. I was forced to put the car in park - while still on the exit ramp - turn off the car and turn it on again to get it to drive normally. Which it did, as if nothing had happened. But it's unnerving and certainly unsafe, and a quick search on the internet reveals it seems to happen quite frequently to other Jeep Grand Cherokee 2012 drivers.

I was driving down an off ramp towards a right turn at about 20-30 mph. I attempted to make the right turn and brake pedal was very hard, gas pedal wasn't responding and steering wheel locked up(no turning). The Jeep slowed and nearly hit parked cars since brakes and steering were not working. When Jeep finally stopped, I shifted into park and pushed ignition off button. I waited a few moments then pushed start button and it started up with no check engine light or service message. I believe altinator or tipm failed while I was driving. I don't believe my vehicle qualified for T37 altinator recall or tipm recall that was issued.

While stopping at a drive-through on my way to work, the brake system experienced an issue. I was at a stop when the brake pedal backed up from the floor and the Jeep started to roll forward.
