1 Blind Spot Detection problem

Failure Date: 02/21/2025

I have a 2021 Jeep Wrangler 4xe rubicon. My vehicle has been recalled three times for updates. I have had one recall done for the defroster due to the faulty software that can cause reduced visibility increasing a risk of a crash. The second one was for risk of fire from a faulty high voltage battery driving or parked. The third recall call was to update software for the high voltage battery in which doing so caused my vehicle not to fully charge and to lose power when driving and not be able to start for hours at a time. I now have brought my vehicle back to the Jeep service center for a diagnostic test and it was found that the high voltage battery pack is faulty in which Jeep has said they will put a new battery in once approved from Chrysler. Jeep has not been able to be able to fix the problem with hybrid battery packs possibly catching on fire or exploding and the new one I'd be getting would risk the same problems possibly injuring or killing myself or any passengers I might have in the vehicle. Jeep is not able to get to the root of the cause of why these high volt battery can go on fire even when they are not in use causing possible property damage to my home or neighbors. I am told in the recall to park my vehicle away from properties and other cars which is impossible to do. I hope you take this serious matter into consideration that Jeep corporation must find a solution for this nationwide problem and for people on the road.

2 Blind Spot Detection problem

Failure Date: 07/01/2024

Hi the two major issues that need to reported. 1. The vehicle would just shut down while driving at highway speeds. It would have trouble restarting and you would have to cost to the shoulder. This issue was random, we took it to the dealership and they drove it for a week until it left them on the side of the road. They kept it for just over a month and a star case had to be opened. 2. 2nd issue, the vehicle would shutter when accelerating and would shutter when braking. Extremely dangerous when trying to drive it back to the dealership. It had something to do with the vehicle not knowing if it wanted to be in electric or gas. This also caused the ac to stop working and the blind spot system not to work . This time they had it for just over a month to change the main battery. Both case the vehicle was unsafe to be on the road and could have led to a major accident.

3 Blind Spot Detection problem

Failure Date: 06/29/2023

Earlier this year vehicle would sometimes do the following, not at start up but when driving; wipers on by themselves & driver can't shut off, turn signals inop, both sides blind spot warning continously on alerting driver every time a vehicle on either side is passed or passes vehicle, anywhere from three to five dash warning lights illuminated. Took to dealer in April 2023 & diagnosed a bad can bus connector. Replaced connector (approx $700). Seemed to be the fix until it started again June 2023. This time all the above issues started up again including loss of power steering. I was on i70 at highway speeds in rush hour traffic and it was very dangerous. Returned to dealer yesterday 6/29/23 immediately following loss of power steering while vehicle was displaying faults & they read codes. They are booked for 2 weeks so I'm scheduled to drop it off 7/10/2023. Dealer has been fine to work with and willing to help. My chief complaint is I have found numerous others that this is happening to (internet Wrangler jl forum) & I feel like car mfg knows about this and is not doing anything about it.

4 Blind Spot Detection problem

Failure Date: 08/08/2022

I was driving down the freeway, came upon traffic which caused me to come to a stop. When the traffic cleared and I put my foot on the gas, the Jeep refused to go forward and stalled out. I had just enough power to get to a safe area on the side of the freeway. My Jeep flashed the d on the gear shifter and I got a notification to put the car in "park. " on the control panel screen it showed "check charging system" and "check transmission. " it also showed a message showing blind spot alert was disabled and the battery light. I had nearly a full tank of gas when this happened and at least 34% of electric left to drive on electric mode when this occurred. My uconnect app showed the message "charging fault error has occurred" when this happened on the freeway.
