NHTSA Complaint #11717388 — 2019 VOLVO XC60

While driving at 10 mph on a residential street, I experienced a sudden and dangerous loss of power braking assistance, making the pedal nearly impossible to depress. An expert Volvo technician has confirmed that the brake vacuum pump failed because the exhaust camshaft, which drives the pump, sheared or failed internally. I want to emphasize that this catastrophic mechanical failure occurred at only 45,000 miles. A camshaft is a non-wear item that should last the lifetime of the vehicle; for it to fail at such low mileage and take out the braking system is an unreasonable safety risk. This is a known issue (Internal Ref: TJ 29131) that directly links an engine defect to a primary safety system failure. The vehicle has been properly maintained, and the failed parts are available for inspection."
