How to inspect an accident car: a comprehensive guide combined with recent hot topics
When buying a used car, checking to see if it has been involved in an accident is a crucial step. Recently, hot topics about second-hand car transactions on the Internet have focused on "the rising accident rate of new energy vehicles" and "the application of AI detection technology in the field of second-hand cars." This article will combine these hot spots to provide you with a structured guide to inspecting accident cars.
1. Analysis of the correlation between recent hot topics and accident cars
| hot topics | Related points | Data reference |
|---|---|---|
| New energy vehicle accident rate rises | Battery pack damage may be hidden | The accident rate of new energy vehicles in 2023 will be +18% year-on-year |
| AI detection technology application | Identifies minor repair marks | Accuracy rate reaches 92.7% |
| Crisis of trust in second-hand car platforms | Accident car refurbished for sale | Complaint volume averages +35% per month |
2. Detailed explanation of accident vehicle inspection steps
1. Appearance inspection
•Paint surface inspection:Use a paint film meter to measure thickness, original paint is usually 80-150 microns
•Seam inspection:The gaps in the hood, doors, etc. should be even and consistent
•Glass date:The production date of all glass should be earlier than the vehicle factory date
| Check site | normal characteristics | Accident car characteristics |
|---|---|---|
| front bumper | There are no signs of disassembly of the fixing screws | The paint surface of the screws is damaged or displaced |
| trunk | Sealing strips are even and smooth | There are welding marks on the rear panel |
2. Inspection of structural parts
•Stringer inspection:This is the key to judging major accidents. The original solder joints should be clearly visible.
•ABC column detection:Use a magnet to test, too much filler will affect the adsorption force
3. Interior inspection
•Airbag:Check the status of the indicator light and whether there are any signs of prying on the edge of the cover
•Seat belt:Pull out all to see if there is any water damage or replace the label
| Interior parts | Check method | Accident signs |
|---|---|---|
| instrument panel | Observe traces of screw removal | Screwdriver scratches are obvious |
| seat track | Check the fixing screws | There is sand or rust |
4. Mechanical system inspection
•Engine compartment:Check whether the wiring harness label is complete and the production date of each component
•Chassis inspection:Lift the vehicle and observe whether there is any deformation or non-original welding.
3. New technology detection methods combining hot spots
Regarding the recently hotly discussed AI detection technology, we recommend:
1. Use the VIN code to query the professional database and obtain maintenance records
2. Use a third-party detection APP to scan abnormal areas on the paint surface
3. New energy vehicles focus on checking battery management system data
| technical means | Detection accuracy | Applicable scenarios |
|---|---|---|
| OBD diagnosis | 85% | Electronic system failure |
| 3D scanning | 94% | Body structure deformation |
4. Summary and suggestions
In the context of recent fluctuations in the used car market, consumers are advised to:
• Prioritize merchants that provide 90-day buyback guarantee
• Be wary of low-priced cars. If the price difference exceeds 15% of the market price, you need to check carefully.
• New energy vehicles require battery health reports
• Always do a road test to get a feel for the steering and braking system before making a final decision
Through a systematic inspection process, combined with the latest detection technology, you can effectively avoid the risk of car accidents and make wise car purchasing decisions.
