While driving and I go over a bump the car jumps to the side. Also lights on dash stay on for seatbelts, tire pressure.
Had new tires put on my Infiniti Qx56. . . . After doing so sounds as if rear end is slipping. I have 3 children and am afraid that this could result in an accident. Horn quit working 1 year after I purchased vehicle. This I know is dangerous because there is no horn to blow, in cases where needed. Fan on blower quit working, only works on high. Passenger seat will no longer adjust. Fan and passenger seat quit working approximately at the same time. No one wants to have an accident, but when you hear things like the rear end and front wheels sound as if they might fall off. . . . That is scary.
Vehicle feels as though it is jumping side by side on the road while driving over small bumps on the pavement. Requires firm grip on steering wheel to maintain control.
While traveling at normal highway speeds any road imperfections, pot holes, bridges, or bumps will cause the vehicle to veer to the right and feel as though you are loosing control. Two hands must be used while encountering anything other than a perfect road. It is extremely scary and unsafe when traveling at speeds greater that 50 mph. It feels as though the rear of the vehicle is getting ready to pass the front. This is our family vehicle and I fear for my families safety while driving. The suspension has been checked and has been found to be in working order although it is obvious something is extremely wrong.
