2011 GC shudders or even turns off when braking hard

Hi everyone,

For the past 12-18 months I've had an issue with my 2011 Jeep GC (5.7L) that has gradually gotten worse.

Whenever I brake harder than normal (e.g. reducing speed drastically to avoid running a red light, a car abruptly stopping in front of me, etc.), the car will start to shudder as it looses power, but recovers and continues as normal. In two occasions that I've had to press the brakes very hard, the car actually turned off. No "service engine" light has turned on except for 24 hours a few weeks back (it went away on its own).

In 2015 I had all outstanding recalls performed on the car. I have an appointment in the dealer next week but would like to know if any of you have any theories on what could be going on so I can arrive at the dealership with some knowledge.

According to TIPM Recall , could be your crank sensor. Symptoms seem to match.

From what I gather from above sub-forum..

Hard to crank = TIPM, Fuel Pump Relay issue
Stalls under deceleration = Crank Sensor

Just my $.02
