Here's an update as of 12-9-15:
1. We've put about $700 into the repair for the ABS and ESC lights going on over 50 MPH. These lights still come on and now Crestmont is blaming a loose exhaust gasket. Our mechanic at Automotive Excellence in North Royalton says the exhaust has nothing to do with the lights. He said they apparently do not know how to repair cars. The right way is to drive the car over 50 MPH and take resistance readings for all four sensors he said. Crestmont apparently did not do this.
2. On 12-8-15 radiator fluid is dripping quickly onto the ground from the side of the engine where they replaced the water pump. They could not take the car last night so my wife left the car there. I called this morning and they are not returning my calls. My wife called and finally around 2:50 they said the car was looked at and they could not find anything but did say the crankshaft pulley was going. They were the ones that replaced the belts and never noted this. When my wife confronted them about this they said that the pulley was fine then. Sounds like they over tightened the belt. Crestmont wants $400 to replace the pulley. I contacted Hyundai USA and they said that the pulley IS covered under the 10 year drivetrain warranty. Crestmont is trying to get money from us and Hyundai for warranty work. These guys are crooks!
