Stalled at Red Light

[rowen727]

I recently noticed that my 2020 Telluride with 58,000 miles was shuttering as I stopped at red lights. It does not happen every time. I thought it was the brake pads and rotors, given that it has almost 60,000 miles. But it also felt like it was about to stall. I thought maybe the A/C was working too hard, or it was something with the stupid auto stop/start, so I shut off the stop/start during a recent short trip. Not long after that, the car stalled while sitting at a red light, and several dash lights came on. It did start back up. But I am not sure what is up.
Does anyone else have an issue like this?

Sounds like ignition problems to me or possibly gas injector problems. When one cylinder is not firing the engine will tend to shudder at low RPMs and stall at idle. In olden times, Chevron Techron would sometimes clear a marginal injector but I am not sure what the right magic juice might be for these direct injection engines. Odds are it won't work anyway but there should be trouble codes to review.

Thanks for the reply!

This actually happened to me today as well. I noticed the shuddering when slowing to slop at intersections and then today it stalled and the dash lights came on while I was sitting at a red light. If you get any feedback about the mechanical fix, please share! I will have to explore the repair options now too.

Changed the oil and the air filter and it hasn't happened again. I think it was lower on oil and the air filter was plugged with leaves.
