For my 2021 Jeep Grand Cherokee, the antilock braking system, hydraulic control unit has failed. It is currently being repaired by the dealership, and I will request the old part so that it is available for inspection. The failure of the abs control unit, disabled the electronic stability control, the forward collision warning system and the cruise control - and the issue appears to be directly equivalent to the current stellantis recall for ram 1500's of a similar year. The dealer was able to reproduce the error - and was inspected at a Jeep dealership.

Frequently all lights go on while driving check engine goes on here and there on the highway. Loud noise when you start the car and continues for about 2 min after the car is turned off as well. . All lights went on and was unable to move the vehicle in the middle of a street. I have taken the vehicle in several times to 2 different dealers and I am told there’s nothing wrong with it. It’s a danger to my family and I for the car to continue to do these things as the car is unable to be moved. .

On many occasions, warning lights come on for no reason. The dealer has "updated" software, but to no avail. . Collision warning, stop/start error, throttle body error and more. On the last event we were driving uphill, approx 25 mph, nobody in front of us, and the brakes slammed on with multiple errors showing. . The car then lurched forward with active breaking, stop start error, throttle body sensor all showing up and going away. This happened 4 times on the evening of Sep 15th. The errors and random and intermittent. . They replaced a "secondary" battery at one point, and that did nothing. They told us we needed to drive it for over 100 miles, to charge the battery, but it did not fix the stop/start or any other error. Now it is in the cerritos Dodge dealer and we have a formal complaint filed with chrystler. . The dealer states they can't find any problems. . During most of the events, the errors and warning lights do not stay on longer than a few seconds. I have one picture I was able to take when the warning lights stayed on a little longer.

Unknown, reared ended an 18 wheeler and the findings do not show that forward collision or steering operated to prevent the accident.
