Warning problems of the 2023 Subaru Forester

The check engine light and a flashing 's' and other lights stating the safety features such as eyesight, lane departure, rab, etc. Are turned off. This started on 1/15/25, and I took the car to the dealership on 1/16/25. The dealership stated the evap system leak detection pump sensor indicated a leak, and the evaporateleak check module needs to be replaced but is back-ordered until mid-March 2025. They turned off all the lights and told me I could keep driving the vehicle. On 1/20/25, all of the lights were back on. The car lags to accelerate and is using gas at a rapid rate. I feel unsafe driving the car for another two months with the check engine light on and the acceleration capacity decreased. The dealership will not allow me a rental vehicle unless I leave it on their lot for two months until the part arrives. I cannot agree with that. The dealership informed me that multiple Forester and crosstreks models have the same problem. This car was purchased brand new from the olympia dealership and it currently has about 22,000 miles on it.
