It’s a simple question: how come some car models pass their NCT test in greater numbers than others?
The answer is not nearly as simple as the mere statistics would suggest. Several complex factors play a role.
Recently released figures from the Road Safety Authority (RSA) show that three SUVs – the hybrid Toyota C-HR, Suzuki Vitara and Renault Kadjar – and the Mercedes Benz CLA were the only cars in the top 200 most popular models to achieve inventory ratios above 80 pcs
The numbers refer only to first attempts. There is usually a high retest pass rate, so we have to be careful not to jump to conclusions too early in the process.
Despite all of that, there’s no doubt that some cars are just better built to withstand the rigors of everyday driving.
Drivers of the popular Toyota C-HR crossover will be pleased to know that the car had an 85.42 percent success rate last year. It’s a relatively new model and benefits from the latest technological improvements. Like all of the manufacturer’s vehicles, it is subject to strict manufacturing standards.
However, if you’re the owner of a Lexus IS200 sedan (Lexus is owned by Toyota), you could be among those who did worst the first time, as it has a success rate of just 27.73 percent. Just to put things in another perspective, Lexus consistently performs well in reliability surveys like the JD Power report.
IS has been around for a long time and age has to play its part. The same is true of many of the other top 10 failures, including the Volkswagen Bora, Nissan Primera, and Chevrolet Aveo, all of which are age-old when it comes to motoring. Age, mileage and wear and tear have taken their toll.
But if age were the only determinant, the Lexus CT200h wouldn’t be in the top 10 highest pass category (78.89 percent) because it’s been around for quite a while too. How can you have one model in the “Best” and another in the “Worst” category to pass the NCT?
Let’s take a look, in no particular order, at what might be the main factors affecting your chances of getting your car through first time regardless of make.
It goes without saying that the more kilometers you drive, the more wear and tear your car has to endure and the more likely it is that this will affect the overall condition of the vehicle over time.
But there are people out there who drive cars with 200,000 to 500,000 km on the clock that run well. Because they are cared for, regularly serviced and driven with care. They’re much more likely to happen.
It’s possible to keep your car in tip-top shape, regardless of age, if you invest the time and money to keep it NCT-Fit. A little like people can ward off little and often a lot of trouble.
Make sure you go to a trusted source for any work done, especially when it comes to brakes, lights and suspension. Bad work causes problems elsewhere in a car.
3. Preparation to test
In addition to regular maintenance, make sure tires and lights are working properly; Windows, mirrors, license plates, etc. must be clean; Seat belts must be fully visible; Top up oil, engine coolant, brake fluid, windshield washer, wipers, etc.
There’s no denying that some cars have earned a great reputation for reliability. They are more likely to be perceived by the public as being built in Japan or South Korea, although many European brands build much more trust as many apply warranties. And the numbers show a good selection of high-rate passes.
There are exceptional situations where people only cover a few thousand kilometers a year. But overall, the average is 15,000-20,000km, so a 10-year-old is pushing big numbers.
In times of scarce used and new cars, if you switch more often when you can, you will have fewer problems later. It also means that due to upgrades in technology and engineering, you drive a safer car and are more likely to get through the NCT unscathed.
6. Let the test discover the errors
Some people don’t bother with a lot of preparation and let the NCT fix the bugs. Then they get the repairs done (or not if they’re too costly) and pass the retest (usually).
Because of this, the numbers can be misleading for the first time unless viewed as part of a larger picture. But it can be a waste of money to “double test” as you will (in most cases) have to pay to retest if a few bucks would have corrected what the NCT discovered.
7. You the driver
A lot of what you do behind the wheel can affect wear – such as: B. heavy braking/accelerating, using the clutch/gearbox excessively when not necessary, etc. The advice is to drive gently and anticipate rather than react to what is likely to happen.
8. Road conditions
Drive ultra-slow on bad roads, as constant, high-impact bumps and shocks can severely affect your suspension and cause rattles that increase the risk of car failure – and a loss in the value of your car when you sell it.
9. Between tests
Finally, remember that you need to keep your car in tip-top shape between tests. They are just a one-day snapshot of your car’s roadworthiness.
