In theory, it is not normal for a brand-new car to have a dead battery. Possible causes include battery leakage, alternator failure, or the car being a stock vehicle. The specific reasons for a car battery draining are as follows: 1. Unclosed electrical devices after locking the car: For example, leaving lights such as high beams, low beams, automatic headlights, or parking lights on can drain the battery. 2. Related to installed accessories: Equipment like audio systems, dash cams, or headlights can also draw power from the small battery. 3. Parking in an underground garage: Weak mobile signals in underground garages can cause the car's internet connectivity features to continuously search for a network, consuming power. Additionally, the mobile app may fail to detect vehicle information in the background.

What is the reason why the right turn signal keeps flashing and cannot be turned off?

Right turn signal keeps flashing and cannot be turned off may be due to relay failure or poor circuit connection/short circuit, requiring circuit inspection. Below are relevant explanations: Relay failure: A relay is a controllable mechanical switch mainly composed of coils and contacts. During use, relays often experience various failures due to reasons such as low product quality, improper use, or poor maintenance. This type of problem can be solved by polishing the contacts or directly replacing the relay. Poor circuit connection: Poor circuit connection in automotive wiring is also known as poor grounding. The main causes are unauthorized circuit disassembly/alteration or position changes by drivers, leading to incomplete connections. For poor connections at plug points, it's recommended to replace the socket end; for loose wiring connections, re-tightening or soldering is needed; for poor connections at control switches or modules, replacement or re-soldering is required.

What does MOT mean?

MOT is commonly seen in automotive sales techniques. It is not only applied in car sales but is also widely reflected in social life, work, and study. MOT (Moment-of-Truth) – the critical moment. MOT is a key indicator, a concrete measure of customer orientation, because from the customer's perspective, they only remember those critical moments – MOT. Additional information: Below is an introduction to the concept of MOT research: 1. In satisfaction research, there is a very important branch called Moment-of-Truth research, which is often used in satisfaction studies for human-centric services. 2. In the 1980s, Jan Carlzon, the president of Scandinavian Airlines, proposed that on average, each customer interacts with five service personnel during their experience with the company's services; within the brief 15 seconds of each interaction, the entire company's impression in the passenger's mind is determined. 3. Therefore, it is defined: every point of contact with the customer is a critical moment, which is approached from three aspects of the personnel: A appearance, B behavior, and C communication. These three aspects are important factors influencing customer loyalty and satisfaction.
