Example complaints

“Camshaft adjuster bolts starting to become loose and back out, which is a known manufacturing defect on those cars, can lead to sudden unpredictable loss of steering and braking, and potentially accidents, especially with very heavy and very fast car like this one. Dealer quoted $4000 to fix with new bolts and adjusters. Attached are pictures taken with a borescope from my engine. I am scared to drive it. This should be a recall. Owners should not be paying for this. Also attached is quote from dealer.”
