new engine

Recently bought a new suv and had to have a crank shaft sensor put in. ..mechanic broke a part on engine and we had to get new one. One month later they said car was done, i picked it up and not 10hrs later, problem again. They had to change valve cover gaskets because they never checked the old ones on the new engine. .cost $100:(. 3 days later check engine light back on and it is leaking coolant. ..worst mechanic I've ever been to. I will never take any vehicle i own to them again and would strongly recommend to anyone to take their vehicle to someone who stands by their work.
