When a car in front of me is slowing down while the adaptive crusie control is on and I have the distance set to 3 or 4 lengths, the farthest one available, and the adaptive cruise control is set, the car will start slwoing down like the cars ahead of me and if I switch lanes to go around of the car that is slowing down and there is another car in front of me of the lane I move into that adaptive crusie control acts as if there is no car in front of me in the lane and will begin to accelerate until I engage the brake. So for example I'm traveling in the far right lane of a four lane road, two going north and two going south. I have my adaptive crusie control on and set to 50 MPH and the distance set to 4 car lengths (max) and then the car in front of me starts to slw down. The adaptive crusie control will adjust and start to slow down as well. So I decide to get into the next lane over to my left, where there also happens to be another car 1 or 2 car lengths in front of me, the adaptive crusie control will not detect that car after lane change and will begin to accelerate back up to 50 MPH when it should still be slowing down to avoid a collision. This has happened multiple times.

My 2021 Jeep Grand Cherokee L experienced a complete failure of the passenger-side headlamp assembly at approximately 70k miles. The entire passenger-side headlamp became inoperative,not just one individual light. I received no headlamp out or exterior lighting warning on the instrument panel. At exactly the same time that the headlamp failed, the vehicle's odometer began flashing. Diagnostic scanning identified fault codes B22204-87 and U1222-00. Disconnecting the battery did not restore the headlamp or correct the flashing odometer. I am concerned because NHTSA Safety Recall 21V-950 (FCA Campaign Y72) involved certain 2021 Jeep Grand Cherokee L vehicles and a Smart Lighting Module software condition that could cause one or both headlamps to become inoperative. I do not know whether this recall condition cause my vehicle's failure, but my symptoms appear similar to the condition described in that recall. I took my vehicle into the local jeep dealership for recall work and included the inoperable headlamp, they told me there was no recall and said I needed to replace the entire headlamp for $1800 or $185 for a system scan. I was not advised of any diagnostic trouble codes, Smart Lighting Module communication, or smart lighting module software status had been evaluated before the headlamp replacement was recommended. I was not informed of a possible software or module-related cause for the failure. Because NHTSA Safety Recall 21V-950 (FCA Campaign Y72) addresses headlamp failure associated with Smart Lighting Module software on certain 2021 Jeep Grand Cherokee L vehicles, I am concerned that my vehicle may be experiencing a similar condition.

The steering started to feel intermittently difficult and then would release. It has been looked at by 2 mechanics and they report that it appears to be a structural failure of the front strut. The strut tower has separated from the body, the adhesive has failed, the rivets have broken loose, and the movement is causing the strut tower to contact the steering shaft resulting in intermittent binding of the steering. All involved believe this is a serious safety defect and a manufacturing issue. Because the car is out of warranty Jeep is denying any reasonability. There have been no accidents with this vehicle and no inciting event.
