2023 Jeep Grand Cherokee Collision Avoidance Problems

Forward collision warning. While attempting to make a left hand turn with a green arrow onto a busy highway, the car suddenly slammed to a stop almost causing a collision. The problem has not been reproduced as it hasn’t been driven again. It is not yet at the dealership. The vehicle has not been inspected. No warning lights prior to the problem.

The 2024 Jeep Grand Cherokee 4xe's Automatic Emergency Braking (AEB) system engaging while turning left when there was no car or pedestrian in front of us. This scared us as the car stopped in the middle of a large intersection putting us all in danger of potentially getting hit. The BRAKE message appeared followed by three loud beeps before the car applied full pressure on the breaks and brought the car to a full stop.

This vehicle does not alert or activate forward collision warnings or automatic braking. Other reports from 2022-2023 by Grand Cherokee owners confirm that the system is not working for many Grand Cherokee.

Driving down a highway in a 70 mph zone, my car’s automatic braking system engaged causing my car to slam on brakes. There were no cars in front of me any of the times this happened. This has happened 5 times in the last two weeks. 3/5 of the times, there were cars/trucks in the right lane next to me. 2/5 of the times, there were trucks two lanes over. The first time this happened, the car behind me had to slam on their brakes to avoid hitting me. This has happened about 10 times since I have owned the car. However the incidents have happened more frequently in the last few weeks.

I have a 2023 Jeep Grand Cherokee 4WD Overland, If the NHTSA would do a web search this issue is a common issue that many people are complaining and concerned about. The forward collision warning with automatic braking is NOT functioning or has been turned down where it is completely ineffective or is not functioning at all. I have had my vehicle in two different Jeep dealerships and have been told that the system is functioning and not showing any error codes. I have an active case working under Jeep (Case # [XXX]) and my vehicle was inspected by a Jeep representative on [XXX], who also claims that the system is working. I have driven several different makes of vehicles with a Collision Avoidance System and have seen and experienced when this system functions properly, I am a Police Officer and currently drive a 2021 Chevy Tahoe with this system and have had many alerts in the two years I have driven this vehicle. I have approximately 12,500 miles on this Jeep and have NOT had one alert with this amount of mileage, I have has a couple close calls where I have had to take evasive action and heavy braking to avoid a collision and not even had a warning of any kind. There are to many people complaining of this same issue and many of the same people are quoting the same company verbiage and quotes from the jeep service departments saying that the system is functioning correctly, and there is no way to test the system. Please look into this issue and research just how many people are complaining of this issue, if your going to advertise and promote a safety system on vehicles you should have an expectation that the system actually works. Any safety system that is not functioning properly puts people in danger when the said system would prevent or minimize damage in a collision situation.

Vehicle made left turn with partially obstructed side view and struck a Pedestrian in a crosswalk. Pedestrian impact with center of vehicle (license plate). No Pedestrian Emergency Braking activated. Vehicle brought to the dealer (with LE Reconstruction) - front radar sensor not tracking. Further tests of vehicle with live pedestrians walking in front of vehicle; both from step off curb into bike lane and live pedestrians walking across the front of the vehicle with no alert or apparent tracking. All tests performed above 3mph (5kph) and below 39mph. Test also above 30mph with lane line activation, but did not detect Pedestrian path intrusion. Inside, the AEB for Pedestrian Emergency Braking is ON, with "Warning + Active Braking". See photos. Tested with all three sensitivity settings (Med, Near, Far). Additional: Rear sensors worked while in reverse with a Pedestrian side approach. Bosch CDR/EDR 900 connected, no Pedestrian option illuminated (only Airbag). Further: Tested another Grand Cherokee with similar trim options, on similar tests and it too did not detect or alert to Pedestrian path intrusion.
