On 8/5/2026, the power boost on the vehicle was lost while at a nearby shopping center. Braking became very difficult and it was dangerous to drive even a little distance. There were no warning lights from the vehicle. We had it towed to an independent repair shop where they determined the brake booster had failed. They did a recall check and saw that it didn't apply to our specific vehicle. They repaired it which cost $2500. Later, we did research and found that there is an expanded recall, 22V315000, which includes our year, make, and model! Our vehicle brake booster failed in the same manner as expressed in that recall. I still have the failed brake booster itself. We'd like you to have Mercedes expand the recall to include our vehicle as well as those with similarly sourced brake boosters. I called Mercedes customer service and they simply confirmed that our vehicle wasn't covered by the recall but to contact NHTSA to file a complaint to start the inclusion process.
