Suzuki: what breaks, model by model

Where the model year matters most

Reliability talk usually stops at the nameplate, and the nameplate is the wrong unit. A redesign changes the engine, the transmission and the electronics; a mid-cycle fix quietly ends a failure that defined the first three years. What follows is the distance between the best-scoring and worst-scoring year of each Suzuki model we can rate. A long bar means the used listings you are scrolling through contain both a good car and a bad one under the same name.

• Vitara Suzuki64–78
• Aerio Suzuki64–78
• Sx4 Suzuki63–77
• Grand Vitara XL-7 Suzuki59–70
• Verona Suzuki68–78
• Esteem Suzuki63–72

Longer is worse: the bar is how far the risk score moves between the best and worst model year of that model. The figures on the right are those two scores, best first, and the colour is the band the worst year falls in.

How to read this page

The report count is the number of complaints owners chose to file with the US National Highway Traffic Safety Administration about that model. It is not a failure rate. A model that sold three million copies will out-report a model that sold sixty thousand even if the second one is worse, which is why every ranking deeper in the site divides by an estimate of how many vehicles are out there before it puts anything in order. Treat the count on this page as a measure of how much evidence exists, not of how bad the car is.

The two score columns come from the model years underneath. Each one is a 0–100 risk score built from how often reports arrive relative to fleet size, how serious those reports are, and how early in a car's life they land — and each is ranked against other vehicles of the same model year, never against other years. That last detail is what makes the columns comparable: a 2003 car is not penalised for having had two decades to accumulate complaints.

Models showing “not rated” have too few reports for a score. On a low-volume model that is a sample-size problem rather than a verdict, and the model page still lists every reported failure and the mileage it was reported at. How the score is built.

Questions this page answers

Which Suzuki model has the most owner complaints?

The Suzuki Forenza carries the most, with 1,360 reports filed with NHTSA across model years 2004–2008. Raw counts follow sales volume as much as reliability, so the per-model-year pages divide by an estimate of how many were built before ranking anything.

Does the model year matter on a Suzuki?

On some models it decides the purchase. The Suzuki Vitara swings 15 points between its best and worst model year — 64 against 78 out of 100 — which is a wider gap than most buyers assume exists inside one nameplate.

Are Suzuki vehicles reliable?

Nothing on this site rates a manufacturer as a whole, because owners do not buy manufacturers, they buy one model year of one model, and the spread inside a single badge is usually wider than the gap between badges. Of the 123 models listed here, 26 carry enough owner reports to score at all.
