I have had bad experiences with engines and powertrains of GM cars. If you plan to keep your car for over 5 years do not buy GM.
My 2001 Chevrolet minivans had intake manifold problems, luckily fixed under warranty. Then, one of the minivan had engine gasket failure. Latest in the saga is that 8 year old Saturn Aura had transmission failure due to failed wave plate. There is a technical service bulletin out there.
But GM gives runaround and does not want to fix it. Says, only some cars are covered for this known defect under warranty extension, but mine is not!
GM covers some cars with this problem under TSB 14404.
They should cover all cars for the model years specified. Lodge complaint with NTHSA https://www.nhtsa.gov/recalls?gclid=EAIaIQobChMI0Kqd-Lzx2wIVi7XACh1aEgu2EAAYASAAEgL1F_D_BwE
