2020 Jeep Wrangler Brakes Problems

The contact owns a 2020 Jeep Wrangler. While driving at an undisclosed speed, the brake pedal became inoperable, and the brakes locked up without warning. The vehicle was taken to an independent mechanic, where it was diagnosed that the brake caliper had failed and needed to be replaced. The vehicle was repaired; however, the failure recurred. The vehicle was taken back to the mechanic, where it was later diagnosed with a failed brake hose, but the part was on backorder. The vehicle was not repaired. The dealer was contacted. The vehicle was not diagnosed or repaired. The contact ordered the parts for the repair from the dealer. The manufacturer was made aware of the failure. The approximate failure mileage was 114,000.

Both left and right brake hoses failed internally causing caliper to lock closed. About 2 months ago I noticed upon application of brakes vehicle would pull hard to the right and the left front caliper/rotor brake system remained locked causing overheating to the point on smoking. This was remedied with replacement of hose, caliper and pads. Recently the jeep began pulling hard to the left upon braking, and the right caliper/rotor brake system were overheating due to the right brakes being stuck closed. Repair has not been completed as replacement parts from Chrysler are back ordered. I feel this is unsafe on multiple levels as it affects braking action including antilock brakes, causes premature wear on pads and rotors, and could create a situation where it affects wheel bearings and other nearby components.

One day, my check engine light came on but when I went to Auto Zone no issues came back. The light came on again a week later so I went back to Auto Zone (I attached the photo of the diagnostic they gave me). I went back to the Jeep Dealership and they said the next available would about a week later but I would be fine in the meantime. I unfortunately was not fine. I attached screenshots from the video of all the issues that popped up during the incident a few days later. My steering wheel locked up while I was driving. My car came to a complete sudden stop like it automatically went into park while I was driving. Then, the windshield wipers started going by themselves. My gas meter went down to E then back up and down. The car not go into park and it would not turn off by pressing the push start button. I had to call a tow truck because I could not move. It was very scary and extremely unsafe. My car has been at the same Jeep Dealership since then on June 17, 2024 with no updates and no repairs. I have been waiting in limbo. I have contacted higher management and even they have given me no answers.

My vehicle had a rough idling and then flashed an autostart symbol and stated on the dashboard that my autodash has been disabled. Later that day I drove my vehicle again, then the dashboard lit up like a christmas tree and every light was on and my car went limp. I pulled over on the side of the road and let my car stay off thinking it would help. Waited some time and tried to turn it on and it wouldnt turn back on until the 5th attempt. took my vehicle to jeep a few days later where they diagnosed it saying it needs a new ABS control module. However, the control module is on back order with no ETA in sight. There are multiple other people in my exact situation waiting 6+ months for their ABS control module. My car is undriveable as it has no traction control, will go limp, and no ABS system. I have been without my car for a month and they have not provided a loaner. To my research this has been an issue since september of 2023 and has yet to be a recall.

When I pressed breaks the engine started to surge instead of breaking. After releasing and repressing the breaks the issue was over. Happened twice in one day, 2/7/2025, the weather was clear and dry, road conditions good. Did not reproduce since then. Not sure how this is even possible.

I am the origional owner of this vehicle. The vehicle has approximately 67,000 miles on it. I own a Mopar premier extended warranty covering the vehicle for 7 years, or 100,000 miles, whatever comes first. My complaint, which I believe creates a severe safety hazard on a public roadway, is the inner front fender wheel lines have failed on three different occasions requiring replacement. When the liners fail, it leaves exposed the 4 individual brake lines from the master cylinder. Road debris, when the inner fender wheel well is missing, can easily strick the brake lines by road debris thrown from the front tire while driving leading to brake failure and loss of control which can result in injury up to and including death to the driver, occupants, or others. I have contacted corporate Jeep on two different occasions to ask for repairs, and they refused to correct the issue. Their position is the vehicle is beyond the 3 year, 36,000 mile initial warranty, and my extended warrenty will not cover the repair as this wheel well liner is considerd a "trim piece". I am looking to NHTSA for assistance as this failure is something that should be mandated for a safety recall, and the dealer has told me the design of the liner on the JL series is prone to failure. I have owned 4 other Jeep Rubicon's over the past 10-15 years, and this has not been an issue on my other vehicles prior to the redesign of current Jeep Wrangler JL series. I have filed a complaint with Jeep, and they refuse to escallate my issue. The dealer says they cannot address the issue without corporate approval, and Jeep does not have a work flow to escallate the issue internally. I have photos which will clearly show the exposed 4 brake lines at the upper edge of the frame rail. I attempted to upload 8 photos of approximately 80-90 KB each. Your web portal would not accept any photos. Help me submit photos for review.

When starting my 2020 Jeep Wrangler all warning lights were flashing. I called dealership and they asked if the car could be driven. Eventually all of the lights went off except service engine and we were able to drive it to the dealer. They did a diagnostic check and could not identify the problem. They then reset the service engine light. One day later the same thing happened again shortly after starting and while we were driving. The car braked on its own without any notice while we were driving and everything started flashing again. We could not shift the car or move it. We decided to have it towed to the dealer. After 3 days they found that the ABS Module had to be replaced. Unfortunately these modules are back ordered for several months. I have no idea when my car might be fixed.
