Hi q phoenix

Worst place I could have taken my. My car had new suspension installed by Hyundai with new clutch kit. I take my perfectly working car for alignment. When they were done I drove home which is 20sec away. I start my car for work and my speed sensors are not working. I have no speedometer and the car is locking itself in and out of traction control. Hi q in phoenix tells me they had nothing to do with it yet everything worked fine before going there. My neighbour took his car to them for alignment and they damaged his breaking system. Poor old man almost went off the road into the bush. And again they insist they did nothing. Please guys don't use them for own good. The owner insisted his a technician and I know nothing because I'm not one.
