 Hmmm.... let's see.... how many people have had happen the EXACT same thing as I have--Bad VVT causing timing chain stretch?Started to happen at 62k miles and thus Mazda is not standing behind the car. Luckily I caught it before it caused a snapped chain and ruined engine.Timing chains are supposed to last MUCH longer, and yet Mazda acts like it is a rare occurrence.I also struggled with the turbo lag.At first I fooled myself into thinking that it was normal for a turbo-until I owned a TDI Jetta--not even close.The unsettling lag and then surge in power at times was almost comical.The longer we owned it, the less an less we liked this car--sold it off for a new Subaru!
