Non Starters

These are the top 10 reasons for car breakdowns, on the 4.2 million breakdowns attended by the AA in 1999. Although the order has changed over the years, most have been main factors since call-outs were first analysed In the 1980s - and correspond surprisingly closely to information from AA patrols going back 50 years

1 Battery. Usually flat because of unusual demand (a lot of short journeys in the dark), lights or accessories left on inadvertently, and/or because the battery is in need of replacement.

2 Tyres. Punctures are rarer than in years gone by but more motorists need assistance in changing wheels and fitting the spare - inadequate jacking systems and tools contribute to the problem.

3 Keys and Immobilisers. This ranges from losing the car key or locking it inside the vehicle to faulty alarm and immobiliser systems. An increasing problem.

4 Alternator. Battery not charging because the alternator or - more often - its drive belt is broken or unseated or is faulty.

5 Fuel. Usually the lack of it. AA patrols carry cans of fuel for sale to those with an empty tank. Sometimes problems with pump or blocked fuel line.

6 Starter Motor. Motor may have failed completely but more usually its solenoid is broken, the power connection unstable, or the engagement gear damaged.

7 Sparkplugs. Problems usually indicate a lack of regular servicing. With modern-day extended service intervals, sparkplug replacement can be overlooked.

8 Engine. Covers a wide variety of problems - often serious. The most common fault is a broken timing belt.

9 Distributor. High-tension leads and distributor have been replaced by more advanced electronics in latest cars but older systems are subject to damp. points out of adjustment and broken insulation.

10 Clutch cable. Surprisingly frequent failure, partly because of twisty cable routes in cars designed for lefthand drive. The AA supplies 35 miles of clutch cable a year!
