An adjuster supposed to have 48 hrs until he/ she comes out and inspect the vehicle it’s been 3 days and haven’t a inspector been out yet this is causing me miss time at work

My previous vehicle had engine issues that caused challenges to get back from work and other needed places.
I went to Drivetime and encountered a good experience of purchasing a preowned vehicle.
Unfortunately, while driving on the interstate several months later, the car began to decrease in speed and all lights came on until I cam to a total stop. I was completely terrified yet thankful that my now inoperable vehicle did not cause an accident while slowly coasting to the side of the road while other vehicles passed by going 70 mph...
I had the vehicle towed in which I was stated I would be reimbursed by the warranty company silverrock (still waiting on that check).
After submitting the claim to silverrock, they assigned an inspector/adjustor that Friday. The policy states inspection of the vehicle takes 24-48 hours. The adjustor was over the policy's timeframe; he/she viewed my vehicle the following Wednesday.
The following week, I was told the claim was approved. The third week, the parts arrive and I was told it wound take two days to repair (engine issues). Then I was told upon the arrival of the parts, one of the parts was broken and needed to be reordered and was told it wound be ready that Friday. Friday arrives vehicle is not ready and I am told Wednesday. Wednesday arrives and I am told a part has been ordered in regards to the radiator.
I call the warranty company in which I was told that the adjuster stated the car will be ready Thursday and they would offer me a per diem amount for the timeframe they were repairing the vehicle.
Engine and radiator issues is unacceptable. I thought I was purchasing a reliable safe car in which I wouldn't have to worry about major repairs for several years maybe more.
I am truly terrified driving the car. It's been 3 weeks, 3 days, and counting that my car has been at the repair shop.
I am truly upset but more do disappointed that this car is a lemon. I will never feel safe driving this vehicle again.
