Recently, a Tesla owner said in the car friend group that his Tesla Model Y accidentally hit the corner of the wall when reversing, resulting in damage to the body. The accident pictures released by the owner show that the entire right rear rear of the car collapsed seriously, and the tailgate, taillights, rear wheel arches, including the triangle window, were damaged to varying degrees.

After the assessment of the insurance company, it was concluded that the maintenance cost of the car was close to 200,000 yuan. The chat records released by the owner show that the model is the standard version of the Tesla Model Y model, which is priced at about 280,000 yuan when the car is purchased, and the maintenance cost of the accident of 200,000 yuan exceeds 71.4% of the purchase price.
In response to the specific circumstances of the accident, Tesla said: The relevant staff is communicating and following up.
Earlier, the premium of new energy vehicles rose, and some insiders said that the increase in premiums was related to the higher maintenance costs of new energy vehicles. A car insurance claimant told reporters that because there is no engine, so the maintenance cost of batteries and headlights, doors, bumpers and other surface coverings is an important factor that determines the claim cost of different new energy models, some new car-making forces due to the lack of substitution of their parts, so the maintenance cost of its surface coverings is higher, and some traditional car companies launched a new energy version of its surface cover may have versatility or sub-factory parts, etc., and the maintenance cost has dropped significantly.
Take the Tesla Model Y in this accident as an example, the car uses an all-aluminum body, and most of the automotive products on the market use a steel body. Compared with steel bodies, when the aluminum body is scratched and damaged, the aluminum material with poor ductility cannot be repaired by sheet metal, and the maintenance is usually directly replaced. In addition to Tesla, brands such as Weilai and Jaguar Land Rover also apply aluminum alloy bodies on a large scale in their products.

In addition, the rear body of model Y uses one-piece die-casting technology, Tesla data shows that earlier production of the rear body of the Model 3 model, it is necessary to use 70 parts to create a structure, and Model Y has an integrated die-casting technology, a giant structural part can replace it. Some car company body engineers told reporters that in the accident, if the body using traditional welding technology only needs to replace the corresponding parts, the cost is relatively controllable, and the one-piece die-cast casting means that the replacement and maintenance costs of parts are rising.
"This deformation has a great impact on the body parameters and may need to be replaced together with the housing." Said the engineer.
In addition, in this accident, there is also a possibility that the three-electric system will be damaged. A new energy vehicle company R & D engineer told reporters: "Even if the use of all-aluminum body and integrated die casting, if only the body damage, the maintenance cost should not reach the order of 200,000 yuan, the car's three-electric system, especially the battery may also be damaged in the accident, as long as the battery is involved, the maintenance price will rise rapidly." ”
