Buick Envision
2.5L Ecotec with port and direct injection, 197 hp. Fundamentally reliable engine with few complaints. Brake vacuum pump is the only notable weakness. Adequate for city driving, struggles on the highway.
Underpowered and boring
197 hp naturally aspirated in a 4,000-lb SUV. Functional, but no joy. The 2.0T is the better choice.

The brake vacuum pump can fail and damage the exhaust camshaft during failure. Affects braking performance. The 2.5L is otherwise very reliable — this is its main known weakness.
Symptoms: Spongy brake pedal, longer braking distances, camshaft noise
