general problems of the 2017 Hyundai Veloster

I bought the vehicle 14 days ago and everything was going well until black smoke started to come out of the exhaust and it started to smell burnt. I brought a mechanic to my house and he told me that the engine had already died.

The vacuum pump had an internal mechanical failure, resulting in complete failure of the airbag control module, electronic stability control system, power steering, abs, and speedometer. These were all shown as warning lights on the dashboard, starting with the esc, then sporadic airbag light, sporadic steering light, etc. . In the event of a crash, the airbags would not have deployed. In the event of low-traction conditions, the car would not have been able to maintain control and I could have crashed. In the event of turning across traffic, my steering could have failed and I could have crashed. Due to the speedometer malfunction, I could have been going too fast and put myself and others at risk for high-speed collision. This problem has been confirmed and repaired by a Hyundai dealership. The repairs would have been covered under warranty, but the vehicle is no longer under warranty. The dealership specified that there was nothing I could have done to prevent this failure. Occurred at 78,000 miles on March 18, 2022.

My blue link connected care has sent me 3 monthly health reports of my vehicle and have all said air bag problem need service immediately but I have no light turned on in my tachometer, I barely got this car 3 months it's too soon to have a problem like this and also have took it to get it serviced . I'm only concerned because if it does come down to a accident will my air bags work?.

The airbag warning light came on soon after I bought the car and I took it to the dealership. They said it was sensor under passenger seat and repaired. A week later, did it again. Said it was probably another bad sensor under seat. It intermittently goes off and on now every few months. I have no idea if the airbag would work if I were in an accident. I haven’t continued to keep taking it back for more new sensors anymore. (I don’t believe every single new sensor they put in has gone bad. ) so I’m at a loss what to do.
