Constant Warning Lights on My 2022 Suzuki Vitara

I've had many problems with my 2022 Model Suzuki Vitara, particularly during downhill drives. The car keeps flashing error messages such as "cruise system review," requiring me to inspect the LDP system, and warning system, disable hill start assist, and service the ESP system. Every warning light on the dashboard is flashing like a Christmas tree. To make matters worse, I've been having issues with phone connectivity, making it difficult for callers to hear me. I took the car back to the dealership several times, including during its annual maintenance, but they couldn't find a solution, and the problems continued. My car currently lacks phone connectivity, forcing me to use my phone manually. My frustration with these issues is at an all-time high.
