Front Air Bag Sensor Control problems of the 2008 Toyota Prius

I was in an automobile accident in Feb of 2015 I hot another vehicle going approximately 15mph no air bags were deployed and the police officer and body shop both were surprised no air bags deployed. I'm curious if this was due to a fault you airbag and luckly I wasn't seriously injured. My dash computer sensor went out in 2015, causing me to not be able to read an odometer, speedometer, etc. I had this part replaced at my expense due to the safety hazard it potentially could cause I'd like to see a formal recall for this part. Toyota acknowledged the safety error and did issue a extended warranty which I was not covered by. I replaced my inverter a third time in 2017 die to over heating. After the recall was performed I did noticed deceased power which greatly affected the performance of my vehicle making it more sluggish. Due to the performance loss I've not been able to use the car for normal trips that were taken previously due to safety concerns.
