2007 Toyota Camry stability control problems

Currently I am having a problem with my ABS and brake light coming on and my module not reading my speed, temperature, or rpms correctly or at all some times. I spoke with a technician that I have gotten work done with before and he told me that he had another customer with the same year same model call in and their car was having the same problem. While the people at my insurance company told me that it may have to do with the age of the vehicle and dismissed my claim.

Moving at 70 MPH, battery light started to flicker. Then 2 loud bangs, like rocks hitting windshield, speedometer wildly fluctuating, check vsc sys light on instrument cluster briefly lit. No loss of power or control. Battery lite now off. Continued on 3 minutes later repeat, bam bam, check vsc sys, now with red triangle warning, ABS light, security, passenger air bag & skid lines flashed on. No problems on return trip, although I was traveling at around 50 MPH.
