We investigated your computer issue and our records show that we did a complimentary oil change on your vehicle. We are sorry that your vehicle is having computer issues but it seems like this problem was pre-existing and had nothing to do with a simple oil change. We suggest that you contact the company in charge of your warranty so you can have it fixed or changed. We strive for excellence in our services so we were disappointed with your one star rating for our shop review. We value your business and hope that we can continue servicing your vehicle.
