Suzuki Kizashi 2010 Problems

Transmissions that are sealed for life always seem like a pretty big statement of faith from a manufacturer, don’t they? Unfortunately, that faith sometimes seems to be misplaced, at which point the car-maker has to issue a service bulletin and change the rules, usually after a number of failures. And automatic or CVT transmissions are a classic case.

That’s exactly what happened to Suzuki in the USA when it issued a Technical Service Bulletin (TSB) to cover the US-market version of your car after enough owners reported CVT problems, usually in hot weather when the unit would start to act erratically. The TSB included the new information that, if the car was used in tough conditions, perhaps a CVT fluid change every 50,000km might not be a bad idea.

Given that Australia has similar levels of ambient heat to the US, I don’t think that’s bad advice for an Aussie Kizashi owner, either. Plenty of other car-makers have had to change their recommendations mid-stride, so it’s not just a Suzuki thing. But as any transmission specialist will tell you, heat kills automatics and CVTs, and that starts with a break-down of the fluid which, as well as providing the drive, also cost and lubricates the transmission. For the sake of the few dollars involved, I’d have the fluid in my CVT changed every 50,000km.

It would seem that a faulty sensor caused it, and the problem has been fixed by replacing it.

The car’s official Suzuki fuel ranking is regular 91 octane.
