Car looses power and goes into reduced engine power. Unable to drive over 2mph. Happens at random times, in all modes of travel, uphill, downhill, from a stop and acceleration. The worst was when it happened going 55mph on a highway. Two separate mechanics have been unable to pinpoint the problem even after $1,300 worth of work and new parts. It's been happening since mid october 2019

Found a broken off exhaust manifold bolt on driveway 3 years ago. Found another broken one today. Both are from the same side. Now instead of 6 bolts I have 4 bolts. This is causing an exhaust leak, engine light and emissions problems that harm the environment. This is an ongoing problem per this article: https://www.youtube.com/watch?v=0yg6wlbnzgi.
