NHTSA Complaint #11631711 — 2017 FORD ESCAPE

The car experienced a sudden loss of boost power and, at the same time, and MUCH more concerning and dangerous, a total loss of brake power assist. The brakes were firm (hard), but had ZERO power assist, and I could barely stop the car at idle in my driveway, much less on a highway or open road. I thank God that my son, who was driving at the time, was not in a dangerous situation when this failure occurred. It turns out, a single vacuum pump, mated directly to the camshaft, applies vacuum boost to the turbo (power loss) and brakes (catastrophic brake failure). I replaced the vacuum pump, but the problem persisted, so I had to take it in to the dealership for evaluation. I was told the problem is the bolt that mates the vacuum pump to the cam shears off when the vacuum pump seizes. I subsequently read of many cases of this problem on the Escape, but also on the F-150 (for which there is apparently a recall???) -- really, any Ford with an Ecoboost turbo engine. Additionally, the bolt shearing and vacuum pump disintegrating, leads to metal shavings that destroy the turbo. How this VERY serious road hazard caused by a terrible engineering design flaw (single point of catastrophic failure) hasn't resulted in a MAJOR safety recall for all these Ford Ecoboost engines is totally shocking and beyond me. This is coming from an engineer who has spent 50+ years working on cars. NHTSA has absolutely failed in not addressing this terrible safety and design problem.
