Honda Accord multi point serviced July 2nd at Hendricks Honda Easley SC. Immediately after I was driving on Haywood Rd. Greenville SC when my vehicle slammed on brakes for no reason. There was no car, animal, pedestrian or debris in road to cause to happen. As a result I experienced whip lash and was seen by a doctor and therapist July 5th. This has caused me to be afraid to drive my own car plus miss work plus enjoy my July 4th. I have reported this to Honda Motor Company and I also returned to Hendricks Honda to have a diagnostic test performed but all they did was put 20 miles on my vehicle and said I would have to bring it in and leave it for 3 - 4 hours. WHY? If you truly checked it out today I don't feel I need to return for them to just tell me anything. I really feel like they wasted time doing nothing today. There diagnostic was just driving my vehicle and adding unnecessary miles.
