NHTSA Complaint #11547691 — 2023 CHEVROLET BLAZER

I purchased this car in May 2023.Since day 1 one the car stalls after filling and out of nowhere. Can be sitting still or going down the highway and highway sped. I took it on snd they could not find anything. Was told to keep track of when it happens. After almost being rear ended several tons and being put in extreme safety I called them and took it back in . They have now had since 9/21/2023 saying they’re some kid of valve problem in the gas tank. So I am paying for a brand new car that is unsafe to drive and is at the dealer for who knows how long .
