Manifold/header/muffler/tail Pipe Problems of Buick Enclave

Purchased 2010 Buick Enclave new on 8/17/08. Had 48800 miles on it, on 1121/16 check engine light came on with code p0008. Took it in garage & discovered timing chain had excessive wear plus replaced both camshafts, valve covers gaskets, timing cover gasket, intake manifold gasket & etc. Was fixed for $3536. 80. On 5/21/18 at 59050 engine light came on again with code p0017 took it back in found timing chain has excessive wear again replaced both intake & exhaust actuators with cam. , intake manifold set, catalytic converter, timing chain because it was prematurely worn, & cam actuator assembly. Sent all documentation to gm but they basically laughed and said sorry out of warranty. I believe something should be done to force them to do a recall & reimburse us for all the timing chain repairs. At this rate we will be replacing timing chain every 10000 miles. They need to recall this engine as there is evidence of major problems with it.
