my car came to a sudden and immediate stop, causing the car behind me to collide with my rear end. in researching this, i have discovered that my car make and model are subject to a class action suit for what is called "phantom braking." I was not injured but the driver of the other car claimed that his son in the back seat was injured. There were no warning indicators going off, either visual or audio. the vehicle's condition was observed by a XXX Police Officer at the scene, and an accident report (XXX) was filed, to be available sometime next week. I contacted my insurance company, State Farm, about 8 PM, after having been directed by an officer to pull around the corner to a side road. they issued a claim # XXX and told me to have the car towed to their approved body shop Bucci's Auto Body in [XXX]. [XXX], the principal at Bucci's inspected the car the following morning and provided an estimate for repairs which State Farm accepted and I authorized to begin. He has not touched any of the electronic data system modules, nor disconnected the battery, and has been instructed in writing not to, so that the forensic evidence can be retrieved. Therefore, there is no information available yet on the mechanical or systems causes of the crash, but it is being preserved for future retrieval and analysis.
