## Narrative
On 8/20/2026 I had a vacuum leak from the intake manifold and crankcase hoses repaired at a Vic's Bimmer Shop in the city of Lancaster California. This included the replacement of the oil separator breather on the engine. I drove my Mercedes Benz 2017 GLS450 less than 100 miles and the engine lost power and suddenly turned off. I was able to pull off onto the side of the freeway and then I saw smoke coming from under the hood and my wife and I exited the vehicle, called the fire department and the car burned completed on the side of the freeway and is a total loss. I believe the oil separator leaked oil onto the exhaust pipe and engine turbo which then started the fire.
