Unless you're a mechanic or some sort of super knowledgable car wizard, you probably aren't aware of the going rate for various car parts. Like, does a new intake manifold gasket cost $20 or $200? Also, what's an intake manifold gasket?
But just because you're clueless when it comes to car stuff doesn't mean you shouldn't do what you can to avoid being taken advantage of when you take your car in for an oil change or to the local auto repair shop.
FIXD is a sensor and app that notifies you when there's an issue with your car or when it needs to be scheduled for a routine maintenance service. The sensor works with any gasoline-powered car from 1996 to today's vehicles. It plugs into a vehicle's OBD-II port, which is connected to the check engine light and operates like a computer to monitor data. Once the sensor is plugged in, it will transfer information to the FIXD app and send you notifications when it senses an issue with your car. If you need to take your car in, the app will provide estimates of repair costs so you don't get overcharged by technicians. Plus, it'll help you understand your car, if you so desire.
