2020 GMC TERRAIN Structurebody Problems

I noticed a sticker in driver door stating recall however no evidence. The vehicle will not pull hills, back up on a hill and will not accelerate over 25 miles per minute. Dangerous to drive on roads. Took vehicle to a GMC dealer for diagnostic test, received the report for what the report found. Took the report to auto shop to get repaired however the vehicle still continues with same issue. Took the vehicle to another auto shop. I was informed of some differences added issues. I had those issues fixed. The vehicle still running the exact way after all of the repairs. The top hood on the vehicle paint starts peeling after a year of owning it. I purchased the vehicle at Kia of Gardendale 2020. No one had any answer regarding the situation. Very disappointed with a GMC vehicle. I just want to know the mystery.

After heavy rain the backseat of the car was flooded as well as the rear wheel well likely due to the sunroof not draining properly. This led to electrical failure of the sunroof mechanism and potential to damage other electrical elements. This will be looked at by the dealership but have read that this is a known issue.

THE COMPLAINT I HAVE IS THE INSIDE FRONT OF THE CAR IS TOO SMALL AND I CANT REACH THE GAS PEDAL EXCEPT WITH MY TOE. MY FOOT KEEPS SLIPPING OFF AS I AM DRIVING. I HAVE TO HAVE THE SEAT WAY UP OR I CANT REACH. I AM 5 FOOT TALL WOMAN. THIS IS A RIDICULOUS THING THAT I HAVE TO PUT UP. I DROVE IT FOR 10 MINUTES AND DIDN'T REALIZE IT. I ASKED FOR A PEDAL THAT IS LONGER AND CLOSER TO THE FLOOR AFTER I HAD BOUGHT IT AND SERVICE PEOPLE TOLD ME THEY DON'T HAVE ANYTHING TO DO TO FIX IT. THEY ASKED IF I HAD A BUTTON TO ADJUST IT AND I DON'T. ITS ON THE EXPENSIVE ONE. THIS SHOULD BE ON ALL VEHICLES FOR SAFETY. I WANTED TO GIVE IT BACK BUT THEY NEVER HELPED ME. I HAVE 1100 MILES ON IT .IT NEW...
