Service techs didn't tighten bolts correctly after installing a timing belt. Several months later bolts broke. When I took the car back to them they told me that impact damage had caused two bolts on the top side of my engine to brake. Car has never been in an accident and shows no signs of impact damage. Furthermore two bolts don't just brake by coincidence on your engine for no reason and nothing you could hit could cause no other damage, but by chance just brake two bolts. They told me I had a cracked block and needed a new engine. I got a second opinion from a very repeatable shop in Berkeley and they confirmed that my car shows no evidence of any impact damage and that the bolts that were broken were from a botched install when I got the timing belt changed previously. Sonnen quoted me 7,000 dollars to replace my engine. Shop in Berkeley fixed my car parts and labor out the door for 800 bucks. They are unwilling to work with me at all on a reimbursement on the botched timing belt install or on the 160 dollars I spent on a false diagnostic telling me I needed to replace my engine block for 7,000. Stay away. I've been a loyal customer of theirs for years, but will never do business with them again. I spoke with a manger there and he didn't care and disbuted me without even looking into the matter or having the facts in front of him. Eye on the bay and a lawyer will have to get there attention since they can't reimburse an honest loyal customer for there screw up and for giving extremely false information.
