2021 Jeep Cherokee driver assistance problems

Filed Oct 9, 2026 · Driver assistance · FL

I am reporting a safety concern involving the Forward Collision Warning (FCW) system on my 2021 Jeep Cherokee Altitude FWD with a 2.4L engine. Every time I start the vehicle, the dashboard displays the warning message "FCW Unavailable – Service Required." The warning remains displayed while I am driving, indicating that the Forward Collision Warning system is not functioning properly. This is a safety concern because the vehicle is equipped with Full-Speed Forward Collision Warning Plus, which is designed to help warn the driver of potential frontal collisions. With this system unavailable, I cannot rely on its collision warning and automatic emergency braking functions. The issue occurs consistently during vehicle operation. The exact cause of the malfunction is currently unknown. I am requesting that the federal safety agency document and review this safety concern and determine whether further investigation is warranted.

My 2021 Jeep Cherokee Trailhawk is currently immobile due to an active safety recall involving vehicle movement/park functionality concerns, and loss of power. Prior to the recall being issued, one certified Jeep dealership inspected the vehicle regarding the concern - with no resolution. Since the recall has now been formally issued, I have attempted to contact both that dealership and the certified Jeep dealership where the vehicle was originally purchased by phone and email to obtain recall assistance, repair guidance, and information regarding transportation options. Neither dealership has responded to my calls or email communication. The vehicle is currently unusable and poses a safetly concern due to the recall condition. I reply on this vehicle for daily commuting and transportation. Stellantis Customer Care was contacted, but a customer care case was not opened. At this time, I have been unable to obtain assistance, repair scheduling information, or guidance regarding the safe operation or transportation accomodations while the vehicle remains affected by the recall.

I purchased this 2021 Jeep Cherokee, and it has developed a life-threatening defect where it performs an uncommanded braking while driving at speed. Without any warning the car slams on the brakes creating an immediate risk of a Rear end collision. Diagnostic scans show multiple critical failures: PO128 (the initial warning of a computer communication issues). Dealership (Echo Park) refuses to fix with the proper OEM part and denies my warranty, (I called it in on day 15 on my Warranty, 01/28/26) I let them know the fans were loud, RPMs fluctuating, tailpipe full of black soot and making a loud sputtering, this is burning up my fuel fast. My appt was on 02/10/26 They said there was nothing wrong with it. A couple weeks go by and then the check engine light turned on (after my Warranty) i took it back on 03/19/26, They visually verified the code, said I had to pay out of pocket to fix it with an aftermarket part not the OEM part. They set up an appt for 03/25/26. UO128 (lost communication with brake control module) and C008E-00(ECU internal performance). These codes are directly linked to the federal safety agency safety investigation PE22- 009. When I took the vehicle to Allways [XXX] on March 23, 2026, the Service Department refused to perform a safety inspection without an upfront payment, despite the vehicle having exposed wiring in the steering column and part of an active federal safety probe. As a small business owner (Maid To Sparkle) grandmother who transports a [XXX] daily, I am now stranded with a vehicle that is unsafe to drive due to a documented a manufacturer defect. While at the dealership I was simultaneously on the phone with Jeep Customer Care. Despite the vehicle being under federal safety investigation for the exact ghost breaking I am experiencing both the dealer and corporate representative denied assistance and refused a safety inspection without an upfront fee This shows a coordinated refusal to address a documented safety defect.

Our Jeep has had multiple accounts of shifting hard, hesitation while shifting, making a hard sound when putting in reverse and now it is having trouble starting up. When we charged the recently purchased (brand new) battery, the vehicle will start up but when placing in reverse it shifts so hard that it sounds like the bottom is dropping out. Now a lot of lights are shining on my panel; the check engine light, the forward collision light, the parking break light, the regular brake notification, the traction control light.....all shining up like Christmas lights. This is an ongoing issue and I feel a recall needs to be done. My car is over the warranty time frame and for a 2021 model that was purchased brand new I should NOT have to be replacing a transmission already and paying out of pocket expenses.

Driving a 2021 Jeep Cherokee Trailhawk on the interstate with cruise control engaged. All of a sudden the vehicle decelerates/downshifts and the display screen flashes "4WD System Unavailable Service Required" and "4WD Neutral Warning". Trying to cross traffic to get to the shoulder of road and almost hit due to deceleration. Press gas pedal and nothing. Traction control light flashes on. Coast cross traffic to shoulder side of the road. Shut off Jeep. Check for loss of fluids and/or parts. Check brakes. Nothing. No smoke. No burning smell. Turn vehicle on. Vehicle automatically engages parking brake. Shift off parking brake and shift vehicle into drive and it makes a grinding noise like its trying to shift into 4WD. Snow mode pops on as well as the FWD Collision light and traction control. Jeep ran just fine until this point and no prior incidents, no bad/hard shifting. NOTHING.

Bought used for my daughter in Jan 2023. Car had 30,290miles. The parking brake has been coming on while she’s driving. She is also getting a forward collision service message, as well as Lane assist service message. It’s gonna cost us $1K to repair. I hope this takes care of the problem. I don’t like my daughter driving a fairly new car with so many issues. The parking brake issue is very discomforting. Also the stop/start function is not working. The mechanic says a new battery will resolve this issue.
