I drive a 2012 Buick Verano, 220 000kms, 2.4L 4 cylinder engine (according to google). The issue started about 5 months ago; I had been driving on the highway for about 2 hours, I stopped to get gas, and as I slowed down to park, my car shut off. I couldn’t drive for more than 5-10 seconds without it idling. I left it sit for an hour, then it seemed fine and I continued my drive (We only had 30 more minutes to go and my family was there to drive me home if needed). It stalled twice more when we got to our destination, again once we slowed down to park. After a day of not driving, we went home and it drove absolutely fine.

After getting home, I took it to a shop who told me it had a bunch of issues worth more than the car. Took it to another shop who told me they tried absolutely everything to get it to stall, and they couldn’t find a single thing wrong with it. That was 5 months ago, and Ive been driving it with no issues since then.

Then today, it happened again. I drove for an hour, then I pulled into my friends driveway and it happened again. It would stall every 2-5 seconds, I couldn’t even put my foot on the break. For a solid minute I wasn’t even able turn the car on or off, it was just completely locked. I left it to sit for about 12 hours, then drove for about 10 minutes home and it was fine again. It sounded a little more sensitive (?) and the engine light was on, but aside from that I had no issues.

I really don’t know anything about cars, but I would seriously appreciate any suggestions of what could possibly be happening. I hope Ive provided enough information.

If it matters at all, I was just told I need to replace my break, struts, and shocks. My car also burns oil but it has since I got it and its never caused any issues. Aside from that it has been well maintained and doesn’t have any other issues I’m aware of.

    Torque converter is a non mechanical connection between the engine and transmisson that uses the movement of the transmission fluid inside it to drive the transmission.

    Once it gets up to speed it will lock the two together, the solenoid unlocks it when you slow down.

    If it doesn’t unlock it will cause the motor to stop turning when the transmission stops turning.
