Authentication case
A company purchased an off-road vehicle. After driving 10,000 kilometers, the vehicle had a problem that it could not increase speed while driving, and sometimes the speed could not reach 50 kilometers per hour. The company sent the car to a repair shop multiple times but was unable to properly resolve the problem. During the repair process, it was found that the parts had signs of prying, and it was suspected that the car was a refurbished car. Therefore, we were entrusted to our company to conduct a technical appraisal of the reasons why the off-road vehicle could not speed up and whether there were traces of refurbishment.
After rigorous research and inspection, the expert team found that the off-road vehicle has the following problems:
1. The vehicle has a surge phenomenon when driving at high speed;
2. The front paint surface has touch-up paint. The phenomenon is that there are traces of collision repairs on the rear of the car;
3. After maintenance, the oil filler cap was not fixed properly, causing the oil to spurt out, posing a safety hazard to the engine;
4. The horn sound is hoarse.
