Suzuki SX4 S-Cross Exhaust System: The Part That Announces Its Own Problems

A Genuinely Useful Piece of Context Worth Knowing About Suzuki's Diesel History — Suzuki SX4 S-Cross Exhaust System
If you're cross-shopping against a diesel Vitara or Grand Vitara, this is genuinely worth knowing: Suzuki has reportedly recommended those diesel models be used primarily for long-distance driving, and hasn't supported warranty claims for DPF replacement where this wasn't followed. This doesn't directly affect this specific model, but is worth knowing as context on Suzuki's broader approach to DPF-related warranty support.
It's also worth knowing that DPFs generally need genuine sustained motorway-speed running to regenerate properly, worth bearing in mind if your typical journeys are mostly short, local trips and you're considering a diesel variant of any car.
