WE HAVE BEEN EXPERIENCING PROBLEMS WITH OUR VEHICLE FROM THE BEGINNING. WE FILED AN EARLIER COMPLAINT. WE HAVE NOT HEARD ANYTHING COMING FROM THAT COMPLAINT, BUT HAVE BEEN IN CONTACT WITH AN ODI INVESTIGATOR. WHEN TRAVELING DOWN THE ROAD, OUR TRUCK HIT A BRIDGE ABUTMENT AND THE CAB BOTTOMED OUT HARD ON THE CHASSIS AND THE CAB SWAYED AGGRESSIVELY TO THE POINT THE DRIVER LOST CONTROL. I WAS IN THE BACK OF THE VEHICLE WHEN IT BOTTOMED OUT AND FELT AN INTENSE PAIN GO FROM MY LOWER BACK AND UP THROUGH MY SPINE TO MY HEAD. THE TRUCK SWAYED AND JERKED AND MY NECK WAS SLAPPED BACK AND FORTH AND I COULD FEEL AND HEAR MY SPINE SNAP IN MY NECK. I HAD AN INSTANT AND INTENSE HEADACHE. I THOUGHT IT WOULD GO AWAY, BUT IT DID NOT. I SAW A DOCTOR AND HE DIAGNOSED INJURY FROM THAT INCIDENT. I HAVE BEEN OUT OF WORK FOR OVER A MONTH NOW FROM THIS INCIDENT. VOLVO HAS MADE NUMEROUS AND UNSUCCESSFUL ATTEMPTS TO FIX MY TRUCK. THE TRUCK IS GETTING WORSE AND IT IS GETTING HARDER TO CONTROL THIS VEHICLE WHEN ON UNEVEN ROAD SURFACES. IT SWAYS SO BAD, PASSING VEHICLES ARE AFRAID TO PASS US AND SLAM ON THEIR BRAKES. I AM AFRAID THAT WHEN I RETURN TO WORK, I WILL JUST GET INJURED AGAIN. DRIVING THIS VEHICLE CAUSES AN EXTREME AMOUNT OF FATIGUE WHICH IS REALLY AFFECTING MY HEALTH. I REALLY NEED THE ODI TO LOOK INTO THIS MATTER.
