I took my 2021 diesel Jeep in for a Y81 Emissions recall on 02.19.24. Since then, my vehicle has had its check engine light go on SIX TIMES with a P0133 alert which refers to an O2 sensor. I have taken it in to the dealership for a resolution six times. Currently, it is set to be diagnosed and repaired yet one more time on 01.22.25. Now we are in the middle of winter and I feel like the vehicle is about to die at intersections and roundabouts when I approach them. I tried to go through an arbitration with FCA USA LLC which produces the Jeep brand and it was denied for a repurchase of the vehicle because the arbitrator felt it was not a safety issue since I still drive the vehicle and they are technically not in violation of the warranty which I did not accept as a resolution. Due to my non-resolved safety concern, I am raising the issue in this forum so hopefully something can be done and others that potentially have the same issue can reach a resolution as well. My hypothesis of the cause of the issue is when the Y81 recall happened, it tuned down the emissions output that was originally higher necessary for the vehicle to run, because I didn’t have check engine lights before. By this tune-down of emissions, the engine is not able to produce the correct output to run the vehicle and thus the random lack of power causing a safety issue, and is currently adversely affecting components that are causing the P0133 O2 sensor to alert.
