5 common errors in new car models
When spending hundreds of millions or billions of dong on a new car, everyone certainly hopes that the car will be perfect for the first few years. However, that is not always the case; for example, new cars can have unavoidable defects.

According to the website Which (compiled from customers in the UK), these faults make new cars no longer reliable and safe.
1. Emission control system failure (5% of vehicles are defective)

| Emission control system fault. |
The main job of the emission control system is to reduce the emission of harmful gases such as NOx(nitrogen oxides). This issue has always been at the forefront, especially after the Volkswagen emissions scandal.
Which looked at a number of cars with emissions control system faults, and found that it wasn’t a matter of long-term wear and tear. A faulty emissions control system would cause a fault light to come on in the instrument cluster. Many drivers also reported losing power and producing thick smoke when the fault occurred.
2. Fault in satellite navigation system (4% of vehicles have fault)
 |
| Error in satellite positioning system. |
There are quite a few new cars under 3 years old that have this problem. While it’s not necessarily a dangerous problem, it can be a real pain if you’ve paid extra for this feature.
3. Battery error (3% of vehicles have errors)
 |
| 3% of new cars have battery failure. |
Battery failures are common in older cars, but Which’s survey found that up to 3% of new cars also have them. The cause may be more down to driving habits than the batteries themselves.
Such habits include: frequently driving short distances, leaving lights on all day, and not unplugging devices that drain the battery.
4. Mechanical brake system failure (3% of vehicles have failure)
 |
| Fault in mechanical brake system. |
Mechanical brake failure is serious and can be dangerous if not detected early. Symptoms of this failure include: screeching noise when braking, the car spinning in one direction and vibrating when you press the brake pedal, and slow acceleration can also be caused by brake sticking.
5. Faulty suspension components (2% of vehicles are faulty)
 |
| New cars can also have faults in suspension components. |
The main components of the suspension system are the leaf springs, shock absorbers and tie rods. If any of these components fail, it can affect the performance of the vehicle and make it very dangerous to drive, especially at high speeds.
Like a brake system fault, if the car leans too much to one side and has poor steering response, then the car is definitely faulty.
