The brake booster of my 2012 Jeep Grand Cherokee that was supposedly inspected and or replaced as part of a recall that I had performed on the vehicle on 12/22/2017 has intermittent failure. Prior to having the recall work performed on the brake booster I had no issues with my power brake systems. However, within a year of having the recall work done I had the BRAKE warning light come on while driving and noticed that my brake pedal was extremely firm when trying to start my vehicle. I made an appointment at a Jeep dealer to have the problem diagnosed and fixed immediately but the problem went away before my scheduled appointment. The problem recurred (BRAKE warning light and extremely firm brake pedal upon starting) about 2 weeks ago. I immediately drove to the nearest dealership and asked that they scan what error code was causing my BRAKE light (suspecting that it was a faulty brake booster but wanting a definitive diagnosis prior to pursuing the matter). Thankfully even though the light had gone off by the time I got it to the dealer they said the error code was still stored and came back as "C0021-02" or "Brake Booster - General Signal Failure" that likely indicates a failing brake booster BUT the dealer also said I was out of warranty and so no work would be covered even though the brake booster recall work led to this dangerous intermittent failure. I have had multiple occasions recently where my vehicle has taken longer to stop than expected and I never know when its going to happen and so I have to leave very long stopping distances now or else risk rear-ending a stopped vehicle if my brakes randomly stop working effectively (also to keep my kids safe from being in an accident when I need to get them to school). I can provide the brake booster for inspection if/when this defective part is replaced properly at the manufacturer or the dealership's expense. The time and specifics below refer to the first time the first time the BRAKE light activated.

The contact owns a 2012 Jeep Grand Cherokee. The contact stated that while driving approximately 55 mph when traffic began to back up. When the contact was attempting to get into the left lane, the vehicle's ahead suddenly stopped. The contact depressed the brake pedal, however, the vehicle suddenly accelerated forward causing them to rear-end the vehicle in front. The air bags did not deploy. There was damage to the vehicle in front where their entire rear end was crushed inward. The contact's vehicle was towed. A police report was filed. There were no injuries. There was no medical attention needed. The dealer was not contacted. The vehicle had not been diagnosed or repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 131,000.
Vehicle has inexplicably, and randomly stalled, and lost power steering and power brakes while operating. This has happened on multiple occasions, during random times of the day/season, while in movement, and while stopped at a traffic light/stop sign. There is no rhyme or reason to how or when this happens, and frustratingly cannot not be reproduced by a mechanic or dealership. When it happens, all other systems that were operating continue to operate (eg. radio stays playing, climate control (AC or heat), and the instrument panel doesn't indicate that anything is abnormal. Safety is a huge concern, as its difficult to control and/or slow the vehicle down, and we have barely avoided collisions. It has been taken to a dealer on multiple occasions, but to no avail, as the condition could not be reproduced. Other than the dealership's service department, the vehicle or component has not been inspected by the manufacturer, police, insurance representatives or others. There were NO warning lamps, messages or other symptoms of the problem prior to the failure. We took ownership from the vehicles first and only other owner (my father in law) upon his passing back in April 2018. The condition happened within months of taking ownership, and has happened at least 8-10 times since then. The vehicle is available for inspection upon request. We would like to sell the vehicle (for this, AND other reasons), but do not feel comfortable selling an unsafe vehicle to anyone. We have incurred rental car costs while the car is in the shop for diagnosis. Upon a quick search online, there was quite a bit of evidence of this condition happening with others.
While driving down a main road, the power steering went out, the brakes locked up, and the accelerator locked up. I had to put the car in park and then turn it off and back on. Yes, it is available for inspection. My safety was put at risk because since my brakes were not working, it means my brake lights also were not, meaning someone would not have seen me stopping and I could have been rear-ended. Others were put at risk because my car could have hit someone else. This has happened 4 other times on different dates and a Jeep dealer has done a fuel pump relay BYPASS twice, but the fuel pump itself was never replaced. There were no warning lamps or messages to warn me about the problem before it failed. I am terrified to drive my own car. This needs to be addressed asap.
I've been waiting well over a year, names on a 'list' at various dealerships for both recalls, specifically the fuel pump. Manufacturer recall numberv62 the federal safety agency recall number19v-813
I have been having my car randomly shut off while in drive for over a year. I'm scared of driving my own car. It has happened to me well over 25 times. I've asked the connecticut dealerships (wetmore's and northwest hills) about this multiple times and as of today they say there is no fix and they can't do anything because there is no fix for the recall. It happens when I'm driving and braking and turning left, such as turning left off a ramp or going down a hill and slowing to turn left or slowing on a big hill at a stop light. The car completely stops. The brakes stop working and power steering is lost. Then I have to put it in park and when I press start it restarts. But this is dangerous. I also have a special warranty I paid for and because there is a recall the dealership said my warranty that I paid $4k for is useless because of the recall. Does someone have to die for this to matter?
Tl* the contact owns a 2012 jeep grand cherokee. The contact received notification of the federal safety agency campaign number: 17v572000 (service brakes, service brakes, hydraulic) and 19v813000 (electrical system) however, the parts to do the recall repairs were unavailable. The contact stated that while driving 60 MPH, she felt a vibration under the front driver's seat. The contact stated while depressing the accelerator pedal, the vehicle failed to accelerate while the RPM revved. The contact stated that the check engine warning light was illuminated. The vehicle was towed to her residence. The contact stated that the failures were experienced 3 times.

The contact stated that the manufacturer exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the failure. The failure mileage was approximately 160,000.
The engine stalled completely while I was at a traffic signal, preparing to make a turn onto a busy highway. Loss of power to brakes & steering since the engine completely shut down. I shifted the vehicle into park, started the engine again, shifted into drive but the vehicle would not move. Eventually (in a matter of seconds) the vehicle lunged forward and I was able to safely drive home.
Tl* the contact owns a 2012 jeep grand cherokee. While driving 35 MPH, the vehicle failed to stop when the brake pedal was depressed. The contact applied the parking brake to stop the vehicle. There were no warning indicators illuminated. The vehicle was taken to jones junction chrysler dodge jeep ram (1510 bel air rd, bel air , md 21014, (410) 879-6400) where a test drive was completed. The dealer noticed failure with the brake pedal, but a failure code could not be found. The technician informed the contact to bring the vehicle back when the failure recurred. The vehicle was not repaired. Prior to purchasing the vehicle, it was repaired per the federal safety agency campaign number: 17v572000 (service brakes, service brakes, hydraulic); however, the recall repair did not correct the failure. The manufacturer was not made aware of the failure. The failure mileage was approximately 58,738.
While slowing down to make sharp turns the vehicle will spontaneously shut off causing the power steering and breaking to not work. There are no error codes that come up and the radio and air/heat continue to work. The only reason you know the car shut off is because the breaks and power steering won't work. This has happened multiple times but you can never recreate the problem on cue. It just happens randomly without warning. This has happened both coming off the highway ramp around a turn and on a normal back road street going around a turn. The last time this happened was 11-13-2019
It was raining I had to start breaking was getting close to a red light, could not stop and crashed into another car and totaled mine and injured me.
I was pulling into a parking spot and transitioning the vehicle to park when the vehicle accelerated. I had my foot pressed firmly on the brake but it did not stop and it went up and over a parking barrier into another parked vehicle.
Jeep turns off and won't turn on for hours then it trued on
I recently purchased this vehicle and it completely shuts off unexpectedly. When it does it affects both the braking and the steering. The first time I was stopped at a light and was an easy fix but the 2nd time I was getting off an exit around 50 MPH. I have young children and now I am scared to drive them around in it. I know in not the only one this is happens, there's complaints all over the internet. There should be a recall before someone dies.
I have had multiple lights pop up on my dash, usually after it rains, but once for no reason. I will be driving anywhere from 20-65mph and the lights will just pop up. (ABS, brake, and traction control lights) once I turn my jeep off and back on, it disappears. But when the lights are shown, my jeep drives a little differently.
I was driving my jeep on the highway at 55 MPH and traffic slowed down. I went to brake to slow down and my vehicle didn't slow. It felt as if my brake pedal went all the way to the floor and I attempted to move into the other lane, but my jeep hit the car in front of me and suffered $9,000 worth of damage. I also was injured requiring surgery on my foot that was on the brake pedal. *dt *dt consumer stated car is repaired.*jb *dt consumer stated I have the invoice, however from my understanding they did not do anything with the brakes. I still feel there was/is an issue with them. I can forward the invoice if needed, but it does not mention the brakes. I did ask the shop and my insurance to have the brakes checked. My father in law picked up the car for me and said that the shop told him the brakes were fine. Consumer did not have issues before with brake system.*jb parts of this document have been redacted to protect personally identifiable information pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).'*jb *dt
Engine stalls for no reason under braking and deceleration. Happens more often when braking and turning. Loss of power steering when it happens. Does not happen frequently , more often in the cold when the car has been started. Cant replicate it when car is hot. Dangerous when it has happened on exit ramps as car has to be controlled with no power steering and car has to come to a complete stop, put in park where it has always restarted. People behind me not happy when stopping on exit ramps. Have brought to dealer after it has happened and the car has not thrown any codes. There is not real pattern to this stalling, but, having to stop the car to restart it posses a danger of getting rear ended. Happens at speeds between 30 to 60. Happens most frequently in rotaries (roundabouts) when slowing down to enter.
Safety recall was done incorrectly, leading to brakes freezing up. Dealership was unable to provide paperwork showing that the recall had been done accurately. According to recall t59/the federal safety agency 17v‑572 a vacuum test should have been completed. If the booster did not pass testing, the brake booster should have been replaced. The brake booster was not replaced, allowing moisture to enter and freezing up. Images of the correct installation should have been taken in order to be submitted for the recall. The jeep was in a shopping plaza, moving from parking lot to another when the brakes froze up. Unable to get call back from dealership service manager. *dt consumer stated rust built up inside, because moisture was getting in. *jb *dt
Tl* the contact owns a 2012 jeep grand cherokee. The contact stated that the vehicle had faulty brakes. On occasion, the brake pedal had to be depressed all the way to the floorboard to stop the vehicle. On other occasions, the brake pedal could not be depressed at all. Pomoco chrysler jeep dodge ram of newport news (12629 jefferson ave, newport news, va 23602, (757) 369-3565) repaired the water shield above the brake booster per an extended warranty. However, while the contact was driving and came to a rolling stop, a minor fender bender occurred with the preceding vehicle. A police report was filed. The contact was not injured. Two independent mechanics diagnosed that the brake booster cable was the cause of the failure. The vehicle was towed to an unknown dealer in williamsburg, va where the brake booster cable was removed and replaced with a new part. The manufacturer was contacted and the faulty part was sent to them for analysis. The failure mileage was 80,000.
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 jeeps. 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.
While braking to take a right turn (braking from ~40mph to 15mph) power steering was lost. Fought the car around the turn, then pressed the accelerator, nothing happened. Looked at the tachometer and it shows 0rpm, tried to brake further and now have no brakes. Coast to a stop. No warning lights showed. All electronics were functioning normally. Placed car in park then started as normal. Model year is 2012z has 130000 miles. This has never happened before. No indication whatsoever of any problem previously

Engine randomly stalls for no reason while in motion, leaving the car coasting with no power brakes or power steering. Once the car is brought to a stop, it will start back up and continue driving as if nothing was wrong. Internet searches reveal that it is a common problem afflicting these models with no clear solution.
