“The check engine light came on, my gas tank needle went down to empty on a full tank of gas and will not come back up, and it stalls. While I was driving.”
NHTSA complaint #11404272, filed 2021-03, 210,702 miles“Engine started chirping, replaced idler pulley and the other stationary pulley and belt, the air condition pump was replaced before winter , well with the recent warm up this spring I needed to use the air, at an idle it works ,some light squeeling, but as you are driving it lacks acceleration, it will go if you hit the gas pedel a few times, but it's pretty scary, as soon as you turn off the A/C it drives normal. I see this has been a problem for others that I have read in various car truck forums.”
