Car troubles are like something that is given free with the car even if you did not opt for it as an add-on. That is true for any car in the world irrespective of cost of the car it will need car mechanical repairs, only the level of trouble varies.
With time and use any of the functions in the car may develop a malfunction. The car manufacturers cannot be entirely blamed for all of them though, here’s why. Due to competition among manufacturers most cars now have the best and latest features and technology. This means addition of more parts or replacement of proven technology with relatively new technology. That is not the only reason though, there are quality issues too. I am limiting myself to the reasons not related to the manufacturer’s quality standards. Even good quality parts fail in due course though the percentage of failed parts will be low. The fact that the conditions that the part has to endure will greatly vary and the possibility of misuse always exists. Take example of clutch plate for example which is damaged due to improper use by the most gentle of the drivers. Just to be prepared for a sudden gear change need few drivers rest their foot on the clutch pedal causing clutch damage.
Gear shifting problems
An example is the gear shift lever itself, where the changes in technology is not the lever itself but in the way it works. Old cars used to have a shift lever that actuates the gears using set of linkages but now they have been replaced by cable shifters. The result of using this design is that no vibration will be felt on the gear lever due to the engine and gearbox working. That is cool as long as it is smooth but the vulnerable part is that as dirt and elements of atmosphere act on the exposed area of the component. This will cause the shifting to be hard over time and can be mistook for a clutch issue. If it is mistaken for worn out clutch it can cause unnecessary clutch overhaul which will cost you dearly.
Noise on applying brakes
Noise while applying brakes is a problem that can arise in cars due to 3 reasons. The first one of them is due to the moisture accumulating on brake pads during parking of the car can simply be neglected. As brake is applied for the first few times noise may be heard and later it becomes normal. This is perfectly normal for any car and does not need attention. But if the noise occurs most of the times during braking the reason is most likely the condition of brake pads and brake discs. If pads are worn out beyond the minimum limit they sometimes make noise. Ideally these should be checked every service and changed before the discs are also damaged due to worn out pads. The noise generally comes when the pads are worn too much and are already damaging the disc. Also noise is not a reliable method to identify the problem in the pads or brake disc. There can be noise due to dirt or any matter trapped in the brake system which can be resolved by doing brake service. The third can be due to quality of brake pads installed in the car. Sometimes low quality brake pads can cause noise while braking this can be resolved by replacing them with good quality ones.
Fogging of windshield
Our third example is an apparently minor one but this is a potential safety hazard. The defogger malfunction and fogging of windshield. Visibility will be impaired by fogging of windshield glasses as well as window glass. Again this can happen due to 3 reasons and the solutions are as different as the reasons themselves.
First reason is not using AC in the correct setting during cold atmospheric conditions. In cold conditions if AC is not effective in the car moisture can build up and cause condensation of water vapor on windshields and window glass. The solution for this is to use AC and direct the vents away from the glass surfaces. In case the occupants feel the temperature is too cool to their liking then heater can be used along with AC to control the temperature at a favorable point. But the AC needs to be on as it will remove moisture from the air and thereby prevent fog on windshield. For the rear glass rear window defogger that works electrically can be switched on and fog will be removed in some time.
The second reason for fogging up of windshield is the misalignment of the AC vents or flaps that control the distribution of AC air to various vents. Recollect the switch that lets you select the vents from which you want air to flow. The options allow you to select between front, front and lower vents, defogger vent near front windshield. This is controlled by a set of flaps actuated by a cam. In some cars this system is controlled by electrical motors. In any case the actuators can get jammed and cause the AC air to unintentionally blow on to the windshield glass. This will in turn cause fogging of glass and can be rectified by clearing the defect in the flap actuator mechanism.
