Financially inconvenienced due to service delay

My husband took his car mid January for service and was told the car needed to be stripped the engine. He was not told when the car would be ready and with multiple follow ups, he was told the parts are being ordered from China and the service job will take 2-3 months. This is such an inconvenience as he needs to uber everywhere while the car is still under warranty. He was told no vehicle is available for him to use in the interim. I then stepped in and made follow ups and was informed that there are internal issues going on at Havel hence the delay. Now how is that ok for the customer as we are heavily inconvenienced. Other brands have courtesy vehicles (I called the car brand I drive Chery). We are still waiting here on and it’s money we are needing to spend on top of the instalments we are paying.
