Left side boost tube blown twice on my vehicle. Technical part info: 204-528-00-00, Charge Air Hose Both incidents involved sudden loss of power in the middle of the free way driving. First incident: Christmas Day 2018, on the way to Las Vegas from Grand Canyon visit, on highway 93. Fortunately, no vehicle was behind when I lost the power, moved to right lane and continued driving slowly to reach the hotel in LV (about 50 miles at low speeds). Check engine light came on immediately after loosing the power. Next day morning, visited the local Mercedes dealer to repair the vehicle, it costed me $520.19 This was in the middle of a long road trip from Phoenix to San Fransisco. Second incident: July 29th 2021, right after I picked up the vehicle from a repair shop to repair the rear bumper. Vehicle pick up was slow, no check engine light. Next day morning, on the way to work on I-17, vehicle lost the power while merging onto Freeway. Almost got hit a by trailer truck which was right behind me. Moved back to right lane and slowly drove to work. Check engine light came on after few minutes of driving. Took the vehicle to repair on August 6th to a local dealer. This time they didn't charge me for the repair and said it's covered under warranty. I don't have any warranty. Seems like it's a design issue with turbo charge air hose and/or a faulty part. It's a real safety issue if it blown in the middle of driving.
