2020 Jeep Wrangler: ABS light or ABS activating

Filed May 2, 2026 · Electrical · PA

The cam bus connector also known as the green star box behind the glove box was defective. I would drive 32-35 miles and my dashboard would light up with 17 codes, abs, 4wd, steering, anti skid, my speed would disappear as well as my mph into three dashes, my check engine light would eliminate as well as service 4wd, pull over to a safe location vechile disabled as the entire jeep slammed itself into park. I can’t imagine what would have happened to me if I didn’t get this resolved and I was going to work driving on the highway doing 55 and this happened and the vehicle slammed itself into park. I would not be here today to tell my story and potentially save other lives as I’m sure this is a known recall and or should be! I called jeep and was notified that this is a known recall but my vin was listed for the recall. So here I am in hopes to get this resolved for all jeeps out there to get this addressed. I would also like to be reimbursed for the parts and labor getting this fixed. I have the video footage of this happening as well and a pic of the cam bus fuse connector showing the burnt electrical components. This will not let me upload a video only photos.. the video is very important in this case and I feel you should have it for this, if so please email me or contact me and I can send it.

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.

The ABS module failed and caused an issue while in the middle of driving it. When the ABS module failed, I lost power steering and other critical functions. When I lost functionality, errors that I saw on the dash included: “service breaks, service ABS, service shifter” etc. Luckily it didn’t cause any accidents. The vehicle is currently at the dealer service department. It has been there for 3 1/2 months waiting on an ABS module that is on back order. The dealer just advised me today that it could be another 3 months. It’s already been on order for the last 2 months.

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.

Check engine, ABS, Sway Bar lights came on. Service shifter and suspension warnings. Loss of power steering almost caused me to drive off road at 30 MPH.

On 8/3/2020 with 300 miles battery is dead. On 8/13/2020 took to dealership and found nothing. 8/13 engine died at a signal and radio shuts down. Jeep is fine for 9 days without engine light on. 8/24 engine light returns on. 8/25 engine dies at a signal,and the radio shuts down. While on the freeway, battery lights, ABS, and traction/stabilizer lights come on. The power steering goes out, and was hard to steer. The heater comes on via defrost vents blasting hot air and unable to turn off. Power acceleration goes out. Very scarey and dangerous. All lights are flashing on dash panel and the car is dies. Jeep towed to dealership. On 8/27 the technician tried to charge batteries for one and half hours on 1st attempt with no success. Technician said battery severely discharged and they could not retrieve information. On 8/31 after hours on a charge on the 2nd attempt, the batteries charge and technician cleared all codes technician drove it a couple of days (mileage is now 670) and because no codes returned "on", says the jeep is fixed. On 9/3 we pick up the jeep. The next day 9/4 new panel lights come on for the parksense system. The dash panel says to wipe clean. They are clean. The turn on/off button light continues to blink. Opened a case # 77098337 with jeep care on 8/31 and have had no help and sent detailed documention and videos of the problems. The cause is definitely electrical with the batteries not being able to hold a charge. We are in fear of driving this jeep and being stranded somewhere remote and have what happened to us happen again ending in an injury accident or death because of the loss of power to steering and acceleration. Extremely dangerous. We thought the jeep was going to catch fire because of the heat coming out of the vents. Please help! I have videos but cannot upload here so took screenshots from the videos.
