I purchased this 2020 Jeep Wrangler from SunToyota car dealership in Holiday, FL on [XXX]. There have been several ongoing concerning safety issues with this vehicle and the car dealership over the past year since I purchased it. My vehicle has had immediate malfunctions and service visits upon purchase. On 12/31/24, the car went to the shop for broken visor (as is) as listed on service invoice- during this same visit I explained that turn signals lights were not functioning properly- was told that it was too much labor and they are aftermarket lights that the dealership cannot fix- dealership did not attempt to rectify the issue at this time. Broken visor/turn signal lights did not function properly upon purchase of the vehicle. In February, the car had what is known as the “death wobble” on major highways [XXX] and [XXX] in Florida, which was an extremely dangerous experience for all passengers in the vehicle. Invoice from 2/27/25 reflects suspension concern in regards to “death wobble” that was rectified, but again highly unsafe, and vehicle is beginning to shake again at high speeds as of December 2025. Invoice from 10/19/25 highlights the turn signal malfunction once again (it was never fixed from previous visit after purchase of vehicle and continued over several months). Car was taken back to dealer. Received call on 11/11 stating it was ready, to receive another call on my way there stating another issue with lights arisen. Received call on 11/12 stating it’s ready again, service advisor not present, and ALL lights flickering severely worse. Spoke to executive director, Dylan, who stated “[XXX] things happen” and walked away. Vehicle stayed at dealership. (Invoice from 11/12 highlights the turn signal issue again.). Vehicle was returned to me on 11/28/25, where lighting and turn signals appeared to work properly. As of December 2025, the turn signals have malfunctions again. When I tried to get in contact with the dealership they didn't call back. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORM

I was pulling into work when my dash lit up with all warning lights, I was unable to shut my vehicle off. I had to disconnect the battery to do so. After a couple hours of being disconnected, it operated normal. Few hours later, went to leave a store and it lit up again, this time my steering was nonfunctional. The common issue was the can buss connector. For several years this has been an issue, apparently a TSB was placed but I am unable to find it. This should be a national recall. This part controls literally every electrical component of this vehicle. It's I intermittent and unknown to when it will malfunction. This creates a huge hazard to driving as when it does malfunction, you're unable to steer, your vehicle can shut off, it's not safe at all. Then come to find that the part isn't even covered as a replacement on the TSB. There is no reason this part should not be recalled, how does a small plastic block become defective other than poor craftsmanship? When the vehicle can't communicate to the other parts (engine, transmission, steering, fuel system, etc) that is a huge problem and is not worth the risk of death because someone can no longer drive or steer when going 65 mph.

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 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.

After having the steering damper replaced for the death wobble on my 2020 Jeep Wrangler, a week later I was driving my jeep down the road and the vehicle stalled out on me. The auto start/stop light turned on and the car stalled out in the middle of a busy roadway in drive and would not go into park. After getting it into park, several lights turned on my dash, including “service power steering” and “service electronic stability control. My shifter lights all began flashing at once and my windshield wipers began to go while they were turned off. The vehicle would also not go into N and after finally getting it into neutral, we had to hold the emergency neutral pull while steering across 4 lanes of a busy roadway. This is now the second major safety issue (1st is death wobble) i’ve had with my jeep and no recalls have been issued. My car is at 42k miles and a lease, these cars should not be having these issues so early! It has now been at Jeep for a week and they have yet to look at the vehicle and keep giving me the run down of “we haven’t been able to look at your vehicle but it doesn’t look good” Jeeps seem to have major safety issues lately.

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.
