Reliability, common problems and owner reviews for the Suzuki Grand Vitara 2.0 / 2.4 petrol (J20A / J24B). Check this before you buy used.
The larger petrols suit the GV's weight far better. Two specific things decide the verdict: the accessory drive-belt rollers/tensioner must be replaced around 45,000–50,000 km (skip it and the belt can fail), and the timing chain tensioner can stretch — when it does the engine audibly 'runs like a diesel'. The 2.4 (J24B, from 2008) additionally has reports of cylinder-head/valve issues and oil consumption. A well-maintained one is great; an unchecked 2.4 is a gamble.
