Hi, I’ve been a long-time reader, but this is my first post! Hoping someone can help me out! I have a small but annoying issue with my 2005 VZ Calais alloytec. I got it in mid 2015 and I love it. Since getting it, I noticed it surges every now and then (usually under load). When starting up...

Hi all, I bought a new SV6 Commodore Sportwagon 6 days ago (straight from the factory, only 17kms on it when I received it). For the first 3-4 days I was amazed at how smooth the car was on start up - completely quiet and still even when cold. The quietest and smoothest car I've ever driven...

Hey, On Monday when I was driving to work i noticed that when I was on the freeway going 100k's that when I accelerated the engine started making this clunking noise and as time went on the noise became more obvious. Then eventually the engine began to loose power so I pulled off and as I...
