The BMW X3 went in for a recall to reprogram the DME. After updating the DME software by BMW the DME was no longer talking to other modules. The BMW Assistant Service Manager said and I quote him "IT'S A KNOWN ISSUE WITHOUT A FIX". I ask for clarification and I was told that there were some 100 modules or so that are in the car and that they now no longer reliably talked with other modules as a result of the updating the DME recall software. I was given one example by BMW of possible implications to modules not talking to each other where BMW was not sure if the airbag was getting correct information. BMW when on to say they were not sure what exactly was and was not affected but they considered it now a safety issue. They have had our BMW X3 since February 7th, 2023 after numerous fix attempts. As of today that would be 101 days at the BMW service department. …

My vehicle is subject to an active safety recall (NHTSA #25V-636) issued in September 2025 involving the engine starter. As of today, no remedy has been provided by the manufacturer. Due to the safety risk associated with this recall, I do not feel safe operating the vehicle and have been forced to keep it parked and unused for an extended period of time. This has caused significant financial hardship, as I am still required to make monthly loan payments, maintain insurance, and cover related expenses for a vehicle that is unsafe to drive. The issue has effectively rendered the vehicle unusable. The manufacturer has failed to provide a repair, replacement, or timeline for resolution. This situation places my safety and the safety of others at risk, as the vehicle may fail to start or function properly without warning. …

I was at a stop light and when the light changed I stepped on the gas. The car suddenly turned completely off. I had no steering, no braking no ability to turn the hazard lights on. I was in the middle of the street with traffic behind me and my child was in the back seat with me. The car completely died. There were no warning signs at all Cars started to go around me and I exited the car with my child to avoid getting hit because I could not put my hazard lights. I called my husband and after about 10 minutes I could see the headlights were on. My husband gave me his care and he took my car home but he said the car was acting weird and kept shutting off while on the way back home. then it shut off completely again in our driveway and we cannot close the doors. We are waiting for BMW to pick up the car tomorrow.
