A car which judders and jolts is not marketable, but then again nor is one which moves in absolute silence. This explains a law in February 2018 which made it illegal for electric and hybrid cars to be silent when traveling at low speed.
The legislation was needed because there is hardly any engine noise, generally the only sound you hear is the sound of tires against the road. There is still debate on whether to use a pretend engine noise or some beeping sound. Porsche went for a Sports car sound.
Ford at the time wondered if police cars could be excused from the law if they needed to creep up on suspects. Although this may help the police or security services a bit, police cars tend to have a look about them, one which not making a noise wouldn’t disguise. It is not clear who the person at Ford made this suggestion.
If you hear any noise when driving its advisable to see a mechanic as quickly as possible, but here’s a short guide.
Squeaking, especially high-pitched, when breaking, means that you should inspect the brakes as they may need to be changed.
If there is clunking, or crunching noise, then there is a problem with the suspension. Your car may also feel unstable and tires may wear quicker than usual if not fixed.
If there’s a groaning noise which gets louder and maybe higher pitched it is due to your bearings. It is best to see a mechanic as quickly as possible.
The sound of ticking is not that unusual in cold weather. However, if it continues it may be something in the engine and is worth investigating.
A hissing sound around the engine suggests a leak somewhere; this must be checked as soon as. A shrieking sound meanwhile in the engine may be serpent belt, which could be age?
A click clack in the wheels suggests that the constant velocity joints in the front wheels need replacing.
Hearing rattling is a common complaint, so you need more information in order to diagnose a problem. It may possibly be a combustion problem, if so, it should be heard when accelerating. If it gets worse, it becomes a hammering noise. Look too at the ignition. Try switching to the gasoline to higher octane.
A howling sound is the differential which leads to work gears.
A slapping sound is a flat tire which should be changed.
If your gear stick makes a grinding noise it suggests that it’s worn out and needs to be fixed.
A banging from an exhaust pipe is known as backfiring. It is due to unspent fuel being ejected from the valves only to ignite in the tailpipe. If you hear a similar noise in the engine it may be something burnt there, or it may be due to spark plugs.
Beware especially of any noise that occurs when you turn a corner. There’s certainly axle trouble.
No wonder every driver hates it when a sound occurs, but if you can fix it quickly then all to the good.
