In September of this year, I would get a random code thrown by the computer, usually telling me that the sway bar disconnected required service, but sometimes it was also the 4wd system. These codes would reset themselves within a few minutes, but I still took it to a dealership for a checkup. The dealership told me that since it currently was not throwing any codes there wasn't really anything they could do. The problem continued to worsen over the next few months. The codes thrown become more varied. I took the vehicle to the dealership two more times and again, no solution was found. Sometimes in the morning when I would go to start the vehicle, it would start, but would not allow the shifter to move, saying that service was required. I took it to the dealerhip again, and no solution could be found. Then the worse started happening. The computer would start throwing several codes at the same time, and then enter a reboot cycle, as I was driving down the freeway. During the reboot cycle, power to the accelerator and power steering would flap on and off, and my ability to steer the vehicle would alternate between powered and unpowered within seconds, leading to a very dangerous situation. The accelerator was the same, disabling my ability to respond to the conditions on the road. I escalated to Jeep's corporate system and left my Jeep at the dealership for two weeks. They were eventually able to identify the CAN BUS as the problem and replace it. I was informed that this was a common problem in Jeep Chrysler vehicles. SInce the replacement of the CAN BUS, I have not experienced any further incidents.

The vehicle begins to shake violently after hitting a sudden bump in the road causing the vehicle to become uncontrollable. This happens at speeds in excess of 40mph. We asked both the dealer and jeep to look at the issue and they said it was not covered by the warranty and there were no warning light indicators.

When you try to accelerate on to highway or try to accelerate to change lanes the engine losses power or the power shuts down. Trying to pass and losing power I had to return to my previous lane and forced several vehicles to slam on their brakes in my previous lane so I could return. Loosing power trying to enter the passing lane forced the vehicle to slam on their brakes that I had just merged into. On another 2 other occasions vehicle looses power when trying to merge onto freeway. First occasion I was able to pull off to shoulder to avoid flowing traffic. Second incident there was no shoulder when merging onto freeway. Semi truck changed lanes to avoid my vehicle because I could not accelerate to speed. These incidents seem to happen with altitude and freeway driving speeds. There are no engine codes showing. This recent incident happened in the Shasta pass area.

Driving on the interstate with cruise control set at 79 mph (dash has digital indicator of cruise control speed, as well) and the vehicle kept accelerating upwards of 90 mph without touching the buttons or gas. Then speed would drop/deceleration would occur intermittently going down as much as 9 mph before I stopped cruise control. I had to pull the vehicle off the interstate, turn it off and back on to enable cruise control to safely function again.

Test drove a 2020 Jeep sahara on 8/7/2020 and drove good. Bought a white one but was not ready so it was going to get delivered the next day at my house. White 2020 Jeep sahara was delivered on 8/8/2020 at around 12:00 pm. Salesman showed all features and left. I did a test drive around 5:00pm, wen on the highway and steering was really off, did a turn around to come back home. At 55 pmh I tried to change lanes and I I lost control and ended up in a ditch. Steeting was very loose going left to right and right to left. Felt I was swerving so much and did not feel the same as the one we test drove at the dealership. Called dealership told me that since the vehicle is still brand new that the roadside assitance was not avaible, left me there in the ditch and I had to call my insurance. This happened in san antonio, tx. Do not buy Jeep!!!
