The contact owns a 2021 Jeep Cherokee. The contact stated that while driving at an undisclosed speed, the radio went black, with the message "Re-insert USB" displayed. The contact was unable to use the radio. Additionally, the rear-view camera, the AC/HEAT settings, and other safety features were inoperable and unavailable. The vehicle was taken to a dealer where it was diagnosed and determined that the radio needed to be replaced. The vehicle was not repaired because the parts were no longer being manufactured. The manufacturer was notified of the failure and informed the contact that the parts were no longer being manufactured. The failure mileage was approximately 92,000.

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.

Incident

Oct 23, 2025

The vehicle was sold by DriveTime (Highland, Indiana) on August 29, 2025, with a known safety recall (Y18 – Transmission Oil Cooler Hose, NHTSA 21V-310) that had not been properly repaired. Jeep dealership documentation dated October 17, 2025, shows the recall was only “inspected” but no repair was completed. Within 30 days of purchase, the check engine light began turning on and off intermittently, and an AutoZone diagnostic (Code P0934 – Hydraulic Pressure Sensor Circuit Low) confirmed a powertrain failure related to the transmission system. The defect affects hydraulic pressure and gear shifting, creating an unsafe driving condition that risks transmission failure while in motion. The issue has been confirmed by both AutoZone and the Jeep dealership but not repaired. Dealer and warranty administrator SilverRock have refused to provide repairs or a loaner vehicle. Both entities were notified that the vehicle is used by a disabled driver and child, and this refusal poses serious safety and accessibility risks. Despite multiple warnings, both companies continue to deny responsibility, violating federal recall obligations under 49 U.S.C. §§ 30118–30120 and creating an ongoing risk of engine/transmission failure while driving. Related complaints are active with the Indiana Attorney General (Case #11811118) and the Federal Trade Commission.

There are times I go to start my car and it has nothing. No lights no door dinging nothing. I started it up on day to go to work and got to the gas station and shut it down to run in quick. Came out 5 mins later and it acted as if someone took my battery out. The car was totally dead. After about 10-15 mins it lit back up and was able to start. Another time it happened in the dead of winter and I was picking my son up. We went to get in the car and all 4 doors were opened. No lights came on and wouldn’t start and as my kids shut doors it would flicker. Times it comes back to life and as soon as you hit the start button it goes black again. It’s been at Tristar and c Harper both and cannot replicate so no fix. I’m afraid it’s going to catch fire or something one day. In the shops for a month and a half total and no results. It’s very intermittent so does not do it all the time. Sometimes it will go a month and be fine then act up 3 times in one week. Please help! I don’t feel safe!

The Jeep caught fire underneath while I was driving on the highway. There were no warning lamps or symptoms of the problem prior to failure. I saw flames come up over the front of the car and immediately parked and ran with my child. We could have died.The fire and stopped car in the middle of the highway could have caused a pile up of crashes. It is unknown what component or system failed and I don't believe it is available for inspection as State Farm decided not to move forward with inspection. They declared it a total loss.

In May 2021 I leases a brand new car. In Jan 2021 I was driving my car and at a busy intersection, my car stalled. I just got a full tank of gas but the low fuel tank light came on. The car would not turn off, the clutch was stuck and I could not shift out of any gear. I brought my car in to the service center where I bought my car and let them know that I think electrical issues were causing problems with my fuel gauge and my clutch. They held on to my car from Jan 20-Mar 28th they could not say what electrical problems caused my car to stall or my fuel tank to register as low but they gave me a whole new transmission. At this time I had only about 2,700 miles on the car. Less than a month later I stalled again on a busy road but I was able to pull the car over and waited for a family member to arrive to help. After letting the car sit for a little I was able to start the car again however the low fuel light came back on and the engine light came on. Additionally this time I was not able to shut off the car, radio, blinkers did not work, as well as break lights did not work. I brought the car back in and expressed my concerns about the electrical problems causing saftey issues on April 20 2021. I drove to the dealership with my hazards in which it stalled 3 times on my way there. They had my car til April 26 and said a cluster of alerts came up and the reset them but they couldn't guarantee it wouldn't happen again. Only one day later I started my car to find the fuel tank alert on again and the car not being able to turn off and brake lights, signal lights were not working and the windshield wipers going crazy. I then called a tow truck to tow my car as it was unsafe to drive. Now my car has been in the shop since April 27 almost 50 days and counting and they still can't find what is causing the issues. They want to release my car again but cannot guarantee it will not happen again. I am terrified to drive the car as nothing was fixed and very unsafe.

While I was trying to get onto the interstate my vehicle would not accelerate. I tried to merge in with traffic but I was only going 35 and I almost hit someone. They stayed the same speed hoping I would speed up in front of them but I couldn’t. This put everyone around me at risk. I took my vh to the dealership. They called me today and told me they sold the rental I was in and that I needed to bring the car back. Also they ran some codes and my car is coming back fine. So they did not find a problem. I honestly feel they didn’t look they just wanted to sell the rental car. I’ve had no warning lamps at all come on but the transmission is slipping.
