BMW iX3 Battery Failure Left My Vehicle in Service for Months

I am the owner of a BMW iX3 with plate number 35 BAF 9**. On 9 February 2026, a “Engine Drive Failure” warning appeared on the screen, and I immediately took the vehicle to the authorized BMW service in Izmir, Turkey. For about two weeks, the service stated that they could not identify the cause of this error. Afterwards, they informed me that the battery protector, which should protect the system against external factors, was weak and had been damaged, and as a result rainwater had gone inside one of the battery groups. Following this finding, I waited another two weeks for the insurance company to carry out its checks. Later, I was told that a new battery group was needed, but as of today I have been waiting for more than two months for this battery group to be supplied. My vehicle has been at the Izmir authorized service since 15 May 2026, and an order was opened on 18 May 2026 with the service file number SORD237940-01. During this entire period, no BMW customer representative has called me, and I have not been provided with any written information. Each time I contacted the service, I was only given the same vague answer of “2 weeks more,” without any concrete date, plan, or official declaration. For a brand that positions itself in the premium segment, I find this level of communication and customer care extremely disappointing and unacceptable. The fact that my vehicle has been left unusable for such a long time, without a clear roadmap or transparent information, has seriously damaged my trust in BMW and in its so‑called premium service approach. I also find it worrying that a weak battery protector allowed rainwater to enter the battery group and cause such a serious malfunction. If this battery group is not available in stock and cannot be supplied in a reasonable time, I question why this vehicle was sold without ensuring proper part supply. Given the long period my vehicle has been unusable, the uncertainty in the process, the lack of communication, and the fact that the problem concerns a main battery group affected by weak protection and rainwater ingress, I expect BMW to replace my vehicle with a new one. I request a clear and definitive solution as soon as possible and an official explanation regarding the delay and stock situation.
