I have only had the vehicle for a year. On multiple occasions the vehicle feels like it is slipping gears (more often when the autostop feature is turned on). On multiple occasions the vehicle has stalled out and would not do anything when pressing on gas- didn't even rev, did absolutely nothing. These stall outs happened crossing highways, at stop lights, stop signs, etc. There were no warnings prior to the incidences, though the vehicle did through an engine/transmission code afterwards, the code would go away. The first several attempts of taking it to the dealership (last year) as it is still under warranty- it was not checked. i was simply told it was a "glitch" and it was fine. They did not record in their system that i requested it to be checked either apparently. They only recorded that i brought it in for an oil change. They only checked into it this February after my boyfriend told them what it was doing. They kept it and replaced one part in the transmission. The vehicle continued to have the same issues and threw a code withing the first 5 minutes after picking it up. I took it back in- and they said it was doing the issues because of the code it threw. I told them it was doing it again before it threw the code. They said it simply needed a line vacuumed out, and then gave it back to me. It continued to have the same issues and stalled out again causing me to roll backwards onto the highway-into traffic. I took it back again. They kept it, and then told me they'd be replacing the entire transmission, but it is on backorder. Still no time frame when it will be repaired. They then told me i could have my car back and continue to drive it until the transmission comes in"!" I said no- it isn't safe, I just told you what happened and i could have been hurt or killed. I am not driving it, especially when i have my son to drive around as well! I have been without my car for at least a month now. I am paying for a car that i don't even have/can't drive.

2/3/2021 I was driving with my daughter today. She was driving and we were approaching a left hand turn at an intersection. We had a green light and I could see that her foot was on the brake. She started the turn with her foot still on the brake. The vehicle accelerated while her foot was on the brake and the steering wasn't responding. We hit a telephone pole. This vehicle was purchased less than 2 weeks ago and has less than 115 miles on it. This is a major safety issue.
