I was on a ski vacation, and when I arrived in North Conway, I noticed a knocking noise coming from the left front tire area. I continued to drive for a few days and the noise became more frequent. I contacted Johnson's, and they got me in the next day to take a look at it. They were very busy, had staff out with Covid, and said they could take a look at the car to see if it was safe to drive, but would probably have to schedule repair later. Definitely not safe to drive. The technician informed me that the lug nuts for the left front tire were very loose, & the tire could have fallen off. He tightened the lug nuts, problem fixed, and no charge for the service. I highly recommend Johnson's. Professional & courteous staff, great service.
