Suzuki Swift 2012 Problems

This model Swift was recalled to check and tighten, if necessary, the bolts that connect the torque converter to the car’s engine. However, if these were to fail or fall out (as happened in some cases) it would be a one-off event and the car then wouldn’t work at all.

Your problem sounds more like a worn transmission which is not accepting the load you put on it when you try to accelerate. This could be worn bands or some other component inside the transmission. CVTs are pretty complex things and rely on physical parts like bands and pulleys as well as hydraulic bits and pieces to take drive to the wheels. It would also be worth checking the torque converter, as a damaged or worn unit can also produce the symptoms you’re seeing. I’d start with checking that the recall was carried out and work backwards from there.

While the less sporty versions of Suzuki’s Swift of this era used a conventional automatic transmission, the Swift Sport used a CVT transmission. And I’m wondering if maybe that’s all there is to your question. The CVT is quite capable of feeling like its slipping when you use lots of throttle, such as when going up a hill or accelerating to overtake. It’s actually quite normal and is the method a CVT uses to maximise fuel-economy by keeping the engine operating in its most efficient zone.

But if you’ve owned the car for some time and its behaviour has changed, then it could be that the CVT is beginning to wear internally. Or perhaps it’s the torque-converter (that links the engine to the transmission) that is starting to wear out and allowing the engine to rev harder than it used to for a given road speed.

Suzuki did recall this model (and conventional automatic versions) to check for loose bolts that secured the torque converter to the transmission. But if these became loose and fell out, you’d have no drive at all, so I don’t think that’s the problem here.

Both are fun cars to drive, they’re relatively new, so should be reliable. I would prefer the Swift; I reckon you’ll get a better run out of it.

Do not buy a Cruze, or buy a European brand. They will prove costly. It's best to go for the cars that are well proven over many years. The Lancer is a good one, but so too is the Toyota Yaris or Corolla, Suzuki Swift, Mazda2 or 3, or Mitsubishi Colt.
