Notes: The 2012 Grand Cherokee hasn’t seen the same complaint volume as the 2011, at least not yet.

It’s worth noting both model years are part of a class-action lawsuit that focuses on a defective TIPM and a long wait for replacement parts.

The 2012 also received national attention after it failed a Sweedish Magazine’s “moose test”. the test measures a vehicle’s ability to swerve out of the way of an obstacle you wouldn’t want to hit while driving down the road … like a moose.

On June 2 after cleaning the car at the car wash (manually) on the way back to our home all the lights of the dashboard lit up for all services to be done and the wipers activated by themselves. The safety belts are no longer working and the lights of the car are not functional. You do not have blinkers, seat belts or brake lights. The RPM needle goes up and down randomly and the engine continues to rev up and down. The brakes feel as if they are not working to full strength, car was turned off and restarted to see if problem with dashboard still exist. Car started with the same problems, but was unable to shift into gear. Car was towed to dealership for service. The car was serviced at brigham-gill dealership (original sales dealer) on 03-June-2013 giving it back to me with the reset of all modules and deemed ok at that point. On 08-June-2013 the same exact problem happened while driving to Virginia beach. Car started same problems experienced on 03-June-2013. Car is at New Jersey dealership for repairs. Car dealer in NJ noted that there was a new computer module replacement to said vehicle in January timeframe. Each time the car has this problem, you are not able to either start the vehicle or move car out of park position.

The incident occurred during acceleration up an entrance ramp incline from 30 mph to 50 mph entering the highway. When entering the highway a vehicle moved into my path at which time, I quickly moved my foot from the accelerator pedal to the brake pedal to find the brake pedal was hard to press and my car did not respond to any brake pedal input, at that moment. I had to swerve to avoid contact with the other vehicle. A very short time later, the brakes appeared to function normally again. I was able to recreate this condition multiple times and brought my vehicle in for service. They were unable to recreate the condition initially. I rode with the technician and walked him through the steps to recreate my experience. He confirmed the condition existed. The dealership has replaced a brake booster vacuum hose and can still create the condition in my vehicle "a brake pedal that is hard to depress and does not slow/stop the vehicle immediately." Chrysler has stated it is aware of this condition in it's pentastar 6 cylinder due to low vacuum brake boost under certain conditions and describes the condition as a "characteristic" of the engine, further explaining the "vehicle is working as intended." While every one at the dealership and Chrysler was nice this is a safety concern that needs to be remedied immediately. Not having responsive brakes under all conditions is not acceptable, this is not a "characteristic" but a design flaw that someone needs to address before too many units are on the roads and experience the wrong conditions at the wrong time and someone is not able to swerve or stop in time. I can't imagine this has not occurred already. There is a "Chrysler start case" with this information in it.

2012 Jeep Grand Cherokee. Consumer states problem with vehicle brakes the consumer stated he had several close calls when he suddenly had to slam on the brakes and the vehicle seemed to take additional time to stop. The consumer stated when the dealer placed the vehicle on the hoist, they found the vacuum line going into the rear of the intake manifold off the vehicle. With no vacuum line and an open vacuum leak, there was no power brakes. The repair amounted to installing the line and a clamp which was not done at the factory. Updated 12/19/12

Grand Cherokee 4WD 8-cyl

Preparing to back from my garage, I stepped on the brake and placed the selector in reverse. Despite my holding firmly on the brake, the Jeep Grand Cherokee moved backwards as if sliding on ice. It collided, at a slow speed, with a car parked opposite on the driveway. While continuing to apply the brake, I moved the selector into drive in order to pull forward away from the other vehicle. The Jeep lunged forward with the front tires remaining stationary and sliding along the ground. The vehicle crashed into the stone column between the two garage doors. The car was damaged to the extent of at least $5,700. There was damage to the building and to one of the garage doors. I am fearful of driving the Jeep Grand Cherokee even after repairs are completed. If I had been in a parking lot or at a stop light there could have been severe damage or injury from this incident.

Yesterday, 5 Jan 12, as I approached a stop light I removed my foot from the gas and applied the brakes. The vehicle did not slow down as expected. It was as if the engine was fighting me. I put the car into neutral and the rpms shot up to about 5000 and then went back down. The cruise control was not engaged and my foot was on the brake, not on the gas. Today, as I was coasting towards an intersection, foot off the gas, I stepped on the brake and again the engine revved up causing me to have to press very hard on the brake to stop. After no more than one or two seconds the problem disappeared. This could easily cause a serious accident.
