Did you ever figure out what was wrong with your Enclave? I have a 2012 that we had the timing chain replaced and a month or so after that mine started doing what yours did, engine shutting off , no codes etc. it does it all the time now so we can’t even drive it, had it to a mechanic and the dealer neither had any luck.id appreciate any guidance you could give as now I have a 2 ton yard ornament And I’d really like to have my car back.

 

I had happened to me. I have a 2019. Did you figure it out?

 

No we have not figured it out the car has not been drivable since last year

 

I have an 08 Enclave CXL, 45k miles -- purchased new, no accidents or major issues ever (minor issues, yes).

This has happened to me over the last month, 4 times. Random times, various speeds, while driving I lose engine power but not electrical power, so I don't know I have a problem until I try to steer or accelerate. No warning lights sounds, nothing. I took it to the dealer and they didn't find anything wrong, they fixed a braking system malfunction and was hoping it was somehow tied into that. But the next day after getting my car back from them it does it again. Today when I took it in, the foreman actually drove it with me and it did it AGAIN (thank goodness because you know it NEVER malfunctions when they are behind the wheel, lol). He is completely dumbfounded and has never heard of this happening -- the strangest part being that no warning lights come up on the dash so that they might have a "trail" to follow to find the source of the issue.

Also, once this happens, it can be restarted immediately with no problems. In fact, after it stalled on the foreman, he shifted into neutral and restarted it while coasting.

They have it now and are going to drive it with some sort of device that is supposed to capture an image of the system, should it do it again.

Has anybody ever experienced this or know somebody that has? It has me very worried and paranoid about my safety, my passengers' safety as well as other motorists out on the road.

Did you ever figure out what was going on with your car? My Enclave has been parked for well over a year now with this same issue, we’ve had it to 3 mechanics 1 dealer and no one can figure out what is wrong with the car. We had the timing chain replaced and it started shortly after that.
