Product: Vehicle loan or lease

On XX/XX/XXXX I traded in my leased XX/XX/XXXX XXXX XXXX XXXX for a XX/XX/XXXXXXXX XXXX XXXX. The initial intention was to purchase it but they said they would give a good deal on the XX/XX/XXXX and convinced me to bring that specific car that was outside. The car did not have the net, and has a lot of water marks on the glass, which has been cleaned with acid 3 times and every time it gets worse, to the point it is difficult to drive at sunset. That is not the major problem. When the car had approximately XXXX miles, on Sunday, XX/XX/XXXX I was driving to a hospital in LA with 2 friends in the car, on the fast lane. Suddenly the car slowed and slid to the left with an abrupt movement. It was very scary. If felt like it hit a pocket of ice. I thought it was normal because it is a new car. I was doing an internship at Hospital so I had to drive about 80 miles each way and I did it on Mon., Tue, & Wed. and Thu. one way, ( about 560 miles ). On Thursday, coming back, when entering XXXX XXXX, I was driving in the middle lane.  Suddenly, the car slip to the left and was very difficult to control ; this time was stronger thant the first time. On Friday I was very afraid so I didn't show up to work and on Sat. XX/XX/XXXX & Sund. XX/XX/XXXX I drove around in town and nothing happened. On Mon. XX/XX/XXXX & Tues XX/XX/XXXX. & Wed XX/XX/XXXX. I drove to and from LA, about XXXX miles a day. I went to XXXX XXXX for a job interview ( drove about 500 miles ). On Wed XX/XX/XXXX, driving on XXXX XXXX to XXXX, I was driving on the slow lane about 55-60 miles/hr and the car abruptally switched to the left and Right in ZigZag. It was very scary. The car has been to the dealership several times to resolve this situation ( after the third incidente ) ... It is now 4 incidents, but they are focusing more on me saying that this bothers me due to my XXXX   condition, than for the problem itself ... indeed, their report looks like a report for the cardiologist and not from a mechanic at a dealership. They drove the car for 75 miles and stated that they could not duplicate the problem and called me stating that the car does not have a problem and didn't even bother tocheck it. I am VERY AFRAID of driving a car that is not stable but mostly, a car that we don't know when the slipping will occur. It looks like the car hits an ice puddle. It was so strong that I was ucky in not having any cars on the left or to the right ... I could have killed somebody or killed myself. I need help. I can not continue driving that car. The promised me at the dealership that they would give me another car, but unfortunately they did not give me another car stating that my credit score had dropped. Anyway, their intensions at the dealership were to take this car back but giving it a much less value, meaning that the car they would give me, would be a totally different deal plus the devaluation on this car, making this way the payments go up to around XXXX higher. 

On their repair orders, actually it is funny ... they do not mention the problem at all. I even told them that the problem had happened 3 times and it had been very scary. 

They removed the " driver 's assistant '' button and told me that the car would be OK. I trusted them and yesterday I almost killed myself!
