my car recently started acting up. i have a 2014 dodge charger r/t i took it o the dealer but they just wanna take money from people just for a diagnostic i was charged $100 just the diagnostic no repairs included. turns out the battery was "really low" so they charged me almot $300 for a "new battery" that my car didnt even need i was so frustraded and mad bevause that still wasnt the problem. i said oh hell no let me tow my car out of here. i looked online and found this vechice code reader my husband plugged it in it told us the code i took it to a diffrent dealer and so i wont get chargd another diagnostic fee i told the the code the car was marking and wala they fixed it. thank you very much once again for saving me a arm and a leg.
