A:An anti-theft device does not guarantee that a car can't be stolen. If you buy a can of pepper spray does that guarantee that someone can't mug you?
If you sue, you have the burden of proving your case. That can be quite a hurdle. Here's why:
Issues you must prove would probably include: Proving by what method your car was stolen, that the device was supposed to stop a theft carried out in the specific way that your car was stolen, proving that the actual theft device on your car was defective, (just because there was a recall does not prove that the actual device on your car failed to work, even though many other purchasers had defective devices). And, how do you prove what else was in your car, other than just your word?
Joining a class action suit is nice. But I have NEVER heard of anyone in the class making any money from a class action other than the lawyers. However, I have heard of people, (me included) who wind up with just a check for $1.98 and a $3-off coupon on our next purchase.
Realistically, your insurance is likely to be the only source of recovery for you. The money you invested in the car has already been returned to you in the form of your use of the car. In the law, your damages are the fair market value of the vehicle at the time of the theft. And if you owed money on the car, your insurance might cover the gap left over between the loan balance minus the value.
