There's no solution, no unified solution. That's the real answer to the owner of the 2019-2022 iron shell ants by august 2026。
The same car, which had been out of the plant since 2023, had all aluminum alloy casings replaced, while earlier the owner had been defending the rusted crust. It's not technical incomprehensible, it's a hard wound from early selection. Chili has not issued any uniform notice of treatment of rust in the iron shell batteries, and all successful cases of shell exchange occurred after the car owner had caused the incident。
Car iron battery casings are severely rusted down
If you have a car in your hand that has no water, no bottom, no self-retrofitting over a period of 8/120,000 km, the path you have to follow is clear and only this path has been tested repeatedly:
You might ask, why do you have to take this step in the media? As of august 2026, none of the publicly available records showed that the owner had been granted a free exchange of the shell simply by submitting a quality assurance application. All success stories are accompanied by advocacy actions or media involvement. This is the common situation of the owners of the steel shells。
Another legal basis you must know is that the shell of the battery is part of the total composition of the power cell, and that the risk of water entry, short circuits brought by rusting is itself a failure of the trielectric guarantee。
The quality assurance commitments announced by the manufacturer were part of the purchase contract, the unilateral reports issued by the battery supplier, which were not certified by a third-party neutral body and rejected, and the lawyer had made a clear statement and questioned fairness。
If you have passed the quality assurance period or don't want to interfere with the rights, there are two ways to do this. The official programme of 4s was to remove the entire battery package and send it back to the polyfluorinated plant to replace the shell and reload it, but the official did not have a single public offer and had to ask for it。
Third-party maintenance is either local welding and rustproofing, addressing only the immediate perforation without treating the root; or the whole shell is replaced at an approximate lower cost than the official one, but the waterproof seal can meet the standard and has to turn off itself。
How do you do it on a daily basis? Every time maintenance takes the initiative to have the battery casing checked, the northern winter runs through the snow melt road and the coastal areas and wash the chassis in time. Car washes are carried out with high-pressure water guns, which sews to the battery pack for long periods, and seals are ageing into water, accelerating internal rust。
In conclusion, the rusted crust is a batch of disease, and chirré does not give a single loop, but the owner of the car has a proven and effective path to rights protection during the quality warranty period. Follow it and get a free shell exchange。
