FORD Escape — What to know
The Escape is Ford's compact crossover with good independent workshop coverage. EcoBoost 1.5T and 2.0T engines are the most common. Some EcoBoost 1.5T engines in 2017–2018 Escapes were subject to a recall for coolant intrusion into the cylinder — verify recall status on any used example.
What is this repair?
Plain-English overview
Vacuum leaks allow unmetered air into the intake manifold, causing the ECU to run the engine lean; symptoms include rough idle, high idle speed and hesitation. Diesel and hybrid vehicles use a mechanical vacuum pump for brake servo assistance, which can also fail.
