Just bought my G8 GT last month had alot of issues with only 40,000 miles. Harmonic balancer went out day after i bought it, decoupler pulley on the alternator went out and had to replace entire unit. Now recently the trans has been clicking when putting into gear P to D, D to R and so on. Brought it to the dealer today on the last day of the factory drivetrain warranty and they said they need to pull the transmission because its internal. Anybody else have the same problem?
