2021 Jeep Cherokee

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 NHTSA 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. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA),

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.

1. Engine timing chain making rattling noise. Yes Automatic Emergency braking activates when there is no collision imminent. Yes 2. Faulty Timing chain can cause significant damage to engine while driving Faulty automatic braking system can cause accident if stopped abruptly in traffic. 3. Timing chain has been inquired by mechanic. Video of the noise. Needs to be confirmed by dealer for warranty 4. No 5. No warning

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.

I put my car in tow mode, after hooking up my RV, followed all proper procedures, after I turned key off and closed the door, between then and when I started to roll, the emergency brake AUTOMATICALLY ENGAGED! I burned up my two rear Jeep tires and could have been worse had not a nice guy stop me and said your tires are on fire!!! I have a 38 ft Alpine, so didn't realize the pull! I luckily only had to replace my 2 rear tires and one sensor that melted! $450. Since then I watch for this DANGEROUS AUTO FEATURE and it has engaged on its own again a few times, not always, but occasionally. I can't have this going on it I plan to tow this vehicle!
