- BYD delivered 1,265 2025-built vehicles instead of promised 2026 models to Australian buyers.
- Automaker claims a clerical error meant date vehicles left factory was used instead of build date.
- BYD initially offered just $1,100 compensation but has now pledged to refund the entire amount.
How long does an owner’s new-car glow last after leaving the showroom? For 1,265 BYD buyers in Australia it was a lot shorter than it should have been after they discovered their supposedly 2026-built vehicles had actually rolled off the production line in 2025.
The Chinese automaker has now offered every affected customer the option of a full refund after initially proposing compensation of just AU$1,100 (US$763). Across more than 1,200 buyers, honoring those refunds could run into the millions.

According to the company, an internal administrative mistake caused the mix-up rather than any attempt to mislead buyers. BYD has also apologized to affected customers and says it has updated its internal processes to prevent the mistake from happening again.
How The Mix-Up Happened
BYD says the problem came from recording the date vehicles left the factory instead of their actual production date. The incorrect information then filtered through its customer systems and into sales documentation, even though the official government records reportedly contained the correct manufacturing details.
Mechanically, there’s no difference between the vehicles. They remain compliant with Australian regulations, carry the same warranty, and perform exactly as intended. That hasn’t stopped customers from worrying about resale values, since a one-year difference on paper could leave owners accepting lower offers when it’s eventually time to sell.
“It was an administrative error that occurred,” BYD Australia PR boss Paul Ellis told the country’s ABC News. “There was no deceit,” he claimed, while also insisting that the U-turn wasn’t prompted by media scrutiny, saying discussions had already been underway.
Price Deals Will Be Honored
Affected models are believed to include the Atto 3 EV, Sealion SUV and Shark pickup. As an alternative to a full refund, customers with the wrongly dated vehicles can swap into a brand-new 2026-built vehicle for what they paid for their original car, Car Expert reports. If they bought while a special offer was in place, BYD says it’ll replicate the deal. Customers can also choose to keep their current vehicle and accept the original AU$1,100 payment instead. Ellis said most affected owners had indicated they were satisfied with that option.
Even if the build-date blunder was an innocent mistake, the fact that it happened at all, and that BYD initially only offered $1,100 compensation, will have hurt its reputation just as Australians had taken to the brand. It has placed second behind Toyota in Aussie sales in April, May and June of 2026, beating more established rivals like Ford, Kia, Mazda and Hyundai.
