Vehicle Shudder problems of the 2018 Subaru Forester

First, driving on the highway the air conditioner stopped working. Second, the very next day, the vehicle began to make noises (squealing) when driving it anywhere. Streets, turns, hills etc. Then it began race and it felt as if the back tires were racing to catch up to the front tires. There was lurching forward. Shuddering. No dashboard warning lights came on. I called the dealership, then took it to the dealership. It was scary to drive it there. I felt like the transmission was going up. Third, the tailgate, ( in or out) release buttons were not working consistently (repeat complaint). I left the vehicle at the dealership and telephoned Subaru of America. This 2018; I had owned for exactly two months. I had only driven the car approx 1200 miles total. Mileage 47,000. The dealer has repaired the ac and cvt transmission. The ac is a known problem and it was the condenser that was leaking and needed replaced. The cvt is also a known problem. The service tech test drove the vehicle and able to duplicate concern. He found the rpm increased and the squealing could be heard. Vehicle would shudder. When he removed the pan he found metal in the oil. Confirming the cvt (transmission) needed replaced. Repairs were made under the extended warranty. Given the information found on the web regarding these problems it was important to report that these problems continue. Safety is concern.
