NHTSA Complaint #11494036 — 2014 BMW X3

The LED chips that control the running lamps in the rear and prone to fail based on my personal experience and reading forums; I've replaced 3 so far. However, BMW has yet to acknowledge the issue and will only sell you an entire brake lamp for $400+. You can find the chip that needs replacing on Amazon for ~$15 with a Lifetime Warranty through the Amazon retailer. During normal operation, these LED lights stay lit in the rear when you're not actively braking or signaling and when you're parking so they're important for any traffic following from behind especially if it's dark. I've seen other German auto manufacturers with similar issues where the rear LED lights no longer function due to defective chips or simply not making them easily available for repair should the chip fail.
