Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering electrical on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
The electrical system of BMW vehicles has been subject to an ongoing development process over the last few years. This has led to increased demands being placed on the battery. This document covers important information for the dealer on how to handle âÂÂdischarged batteryâ complaints.

The failure pattern owners describe
Owners report multiple distinct electrical failures on 2015 BMW 328i vehicles. Rear tail light connector melting is the most common complaint—the left rear tail light connector melts, burning out prongs and causing turn signal and brake light malfunctions. Owners identify undersized ground wires in the tail light assembly as the root cause, citing design defects that allow connector overheating. These failures are intermittent at first, then persistent, with some owners reporting the connector fully melted.
A parked, locked, and powered-off vehicle caught fire in its engine bay while in an enclosed residential garage, with first responders confirming engine compartment origin. The manufacturer did not inspect the vehicle before it was disposed of, preventing investigation.
Trunk electrical malfunctions prevent locking and opening via fob, buttons, or latch; the emergency rear-seat release is the only workaround. Tire Pressure Monitor systems report false warnings intermittently over years of ownership. Driver's door electronic locks fail intermittently, trapping occupants without mechanical backup. Hands-free tailgate systems malfunction—failing to open on foot gesture, dropping partially, and closing without warning. Power loss during highway driving and check engine lights tied to engine coolant pump recalls (NHTSA #24V-608) leave vehicles inoperable or unsafe. Multiple owners smell burning plastic and see smoke from the dash or hood, citing fire risk, with no available remedy from BMW as of early 2025.

There has been an open recall since August with no remedy as of now still. My concern is this is an electrical issue and the safety concern for this recall is possible fire.
My 2015 BMW 328i x drive left turn signal and left brake have malfunctioned since I bought the car. The same thing happen in my mother's BMW 328 series as well and a recall was open. There is a open recall on the brake light and turn signals but not for my actual vehicle. I have replaced the bulbs so I know it is something electrical. BMW refuses to fix the problem although it is a known recall!…

I have only been given the…

Driver's door intermittently fails to lock and/or will…
