Have you ever noticed that buying a car is like choosing a partner? I really regret the wrong choice!
For example, many fans have complained about their cars recently, either there is a problem here, or it is not easy to use there.
In fact, these problems are not unique, but "common problems" unique to some models.
Today I will share that those models that have repeatedly been on the "black list" have long been reminded by insiders that it is best to buy carefully.
01 Cheap small electric car
Although these trams are really cheap, they are also very suitable for urban commuting: if you don't have an option, it's best not to get one!
It's not that the body material is a problem, after all, it's only a car of tens of thousands of yuan, and everyone has expectations in their hearts.
Why?
The reason is that an excellent pure electric car must not only have qualified battery cells, but also have excellent thermal management system, battery management system, flame retardant materials and so on.
But can cheap small electric cars be sufficient? It's really hard!
Don't think this is alarmist, know that the battery will heat up quickly whether it is charging or discharging.
If the thermal management system cannot effectively cool down, it is easy to have a "thermal runaway" phenomenon, which will eventually lead to spontaneous combustion or even burning of the vehicle.
For example, in June 2022, in the parking lot of Yixin City in Haikou, Hainan, a cheap small pure electric vehicle spontaneously combusted while charging, and an explosion occurred at the same time.
This is not an isolated case, and similar situations actually occur every summer!
Although many people will think that cars with small batteries are not easy to catch fire - but this kind of thing is good to listen to.
Because the failure to catch fire has nothing to do with the size of the battery, it is related to safety redundancy.
If this theory is really reliable, then it stands to reason that the "battery car" is the safest.
But is that the case? Not at all!
02 Software Tuning Bad Tram
I'm "funny" when I mention this question, because it's 2024, and many people are still convinced that traditional car companies are more reliable: they have rich experience in car manufacturing, and the chassis and tuning are more solid!
However, if this logic were true, such as not being beaten.
Because in terms of car manufacturing experience, no one can compare with them!
But the reality is cruel, and the feedback from the market tells us that "the logic of the tram has changed", and the software tuning is much greater than that.
It is also because of this that Volkswagen will cooperate with Xpeng Motors, gradually abandon its own electronic and electrical architecture, and begin to cooperate in the development of CEA (China Electronic Architecture) architecture.
Why is this outrageous?
In a way, the software controls everything and becomes the brain of the car.
Considering this situation, once the software is not powerful, the next step will definitely be big trouble!
This is not to scare everyone, because there are many users complaining:
In addition, a certain brand of tram even drove and suddenly stopped on the road and began to update automatically...
The owner can only restart and start hitting the road!
03 New energy vehicles converted from oil to electricity
In fact, I have talked about this topic many times, but many people still disagree and think it is irrelevant.
But if you dig a little deeper, you'll see that the problem is more than that.
Because this kind of car is essentially the design structure of traditional fuel vehicles, forcibly "stuffed" into the electric system.
For example, the chassis architecture of a fuel vehicle is usually designed to accommodate the engine, gearbox and other components.
What the tram needs is a high-capacity battery pack.
If the chassis structure of the oil truck is modified, there will be problems that directly affect the handling and safety of the vehicle.
A more serious problem is that there are also natural shortcomings in the heat dissipation and electrical architecture of oil-to-electric vehicles.
The heat dissipation system of a combustion engine is designed for the internal combustion engine, while the battery pack and motor of an electric vehicle require a completely different thermal management system.
Considering this difference, models that switch from oil to electricity often have the problem of low "thermal management level".
Especially in long driving or hot weather, the battery and motor tend to overheat, resulting in degraded performance or even failure.
Due to the unreasonable internal layout, the security of the battery is lacking, and it is often more likely to spontaneous combustion in serious car accidents.
In general, buying a car is a technical job, not only to look at the "hardware", but also to pay attention to the "software" and the overall design.
Battery management, safety systems, and software tuning are all indispensable.
The neglect of every detail will bring endless troubles to the future life of the car.
I hope that when you choose a car, you will not only make a rational choice, but also have more responsibilities for yourself and your family!
