Our j30 battery became drained because our brake lights stayed on even when the car was turned off. Jeff and Richard and staff analyzed the problem, brought us in quickly and soon had us back safely on the road. They serve up great customer service, display huge automotive knowledge and insure a customer learns all the options for a service issue along with their recommendations. They also now replace tires. We have purchased three sets in the past year! Prices are very competitive with free rotation. We feel very lucky to have these Master Mechanics on our side, keeping us safe and our vehicles running like new! Thank you, Nisstech. Linda and Dan M.
