11 October 2002: The majority of cars on our roads have mechanical faults relating to safety components such as tyres, lights and brakes. This was the finding of a series of checks carried out in the Greater Dublin area last month by RAC Ireland. And things might be worse, as the study only involved voluntary checks.

Over 400 cars were subjected to a 26-point examination by qualified mechanics from RAC Ireland patrol units. The units were stationed in various car parks around the city and county and motorists were invited to have their cars checked free of charge.

Over 60% of cars failed the check on at least one criterion. One quarter of all cars were found to be on faulty tyres – in most cases tyres worn below the legal tread depth, but also tyres with sidewall damage due to cuts, nails, etc. Oil was the next most prevalent source of failure, with 18% of cars checked having inadequate oil levels. One in six cars required attention to lights, typically rear light bulbs, while in 14% of cases wipers and washers were not functioning properly.

Worryingly, more than one in ten cars exhibited brake-related faults, ranging from brake pads and fluid to handbrakes.

It was not only older cars that were found to have faults. Exactly 50% of the 94 cars examined registered from 2000 or later were found to have at least one fault.

Faults uncovered by the checks were as follows:

Condition of tyres 25%;
Engine oil level 18%
Lights 16%
Wash/wiper operation 14%
Brake–related faults 11%
Coolant/antifreeze level 5%
Windscreen condition 4%
Wheels 2%
Exhausts 1%
Other 12%

Robert Taylor, Managing Director, RAC Ireland, says that one in four cars are on worn or damaged tyres is a huge cause for concern. Likewise, the prevalence of faults relating to brakes and lights poses a major safety threat to fellow motorists, especially in winter conditions.

“Simple faults like worn wipers and washer fluid – again, important safety items in winter – indicate even a minimum level of maintenance is wanting. Failure to ensure sufficient oil level will increase wear and tear and ultimately lead to engine failure.

“This check shows we cannot rely on the National Car Test to ensure cars on our roads are roadworthy,” continued Mr. Taylor. “Indeed, 50% of newer cars, outside the remit of the Test, were found to be faulty. Drivers need to be responsible for their vehicles – this means regular DIY checks in addition to scheduled servicing.”
