NHTSA Complaint #11505478 — 2016 CHEVROLET SUBURBAN

I purchased my 2016 Chevrolet Suburban from Jupiter Chevrolet on March 18,2021 at that time the car had 74,931 miles on it after driving off it home 35 min away from the car lot I noticed the RPMS would go up on their own I called and asked what the cause of it and they would be said that it was normal because these new vehicle have the downgrade break. I drove it off and on since then this is a vehicle used for when we have a family trip or just store runs. My truck currently has 107,750 miles on it, that is a total of 32,819 miles put on this truck since 2021. On January 28,2023 as I was driving on the highway to the store that is three miles down the road the truck went into limp mode all the sudden Iwas almost hit by an 18-wheeler because it suddenly owed down and would not go over 20 mph. My daughter who is 5 years old was in the car with me at the time. I was able to turn around and slowly get it back home since I was not far, when I got home the check engine light came on I had my neighbor read the code and it said P0700 and P0796 they said to change the fluid and it would probably fix it so I took it to have the transmission oil changed and new filter put in and they told me then that I will need a new transmission because of all of the metal shavings that was in the oil and filter and on the magnet in the oil pan. There is no recall on this problem, I do not have that many miles on my car and have not driven that many miles to be having a transmission problem on my vehicle this is something out see on vehicles with 300k. miles on them. I must have my vehicle and right now I am not able to drive it at all, but I am still having to make the payments on a vehicle I am not able to drive.
