Transmission without warning; "check engine light'. It was collision. I made a left turn from the stop sign when I pulled into the path of the vehicle which had the right way. I saw white vehicle and it was little further and I can make it to turn left without collision. But the suv won't let me move to 2 lanes and collision. I remember that one day before collision. I notice that rpm was 5 when I was on highway after traffic light. It is not normal for rpm 5 and usually 3. NO warning - 'check engine light'. I feel that it is not safe without warning. The grandchildren and I were in accident and escaped from hurt. Airbag curtains are really work.
