My vehicle was diagnosed in August of 2026 with a suspension thrust arm failure showing leaking hydraulic fluid. The repair cost was quoted at $2,200.00. I found on the internet a BMW of north america service bulletin that called out these thrust arms can fail due to "Various external influences can cause premature aging of the tension strut hydro-mount elastomer; whichcan lead to cracks in the material, and leakage." The service bulletin noted that BMW covers repair costs (parts and labor) on this for cars within the new manufacturer warranty which unfortunately my car had just passed the manufacturer warranty. It is clear these have been leaking for some time and likely failed well before the manufacturer warranty expired but was only diagnosed later. This is clearly a defective part as noted by BMW themselves and for them not to provide coverage of this which is also a safety concern is what I am writing about.
