Information checked: November 12, 2026, at 1:31 a.m. London time, Greenwich Mean Time (GMT, UTC+00:00). This is the time of this report’s source review, not the time of BYD’s announcement.
BYD has confirmed that some Da Tang electric SUVs were fitted with the wrong front and rear wheel rims, and it has announced free inspections and corrective work for affected owners. In a statement issued on November 11, 2026, in China (China Standard Time, UTC+08:00), the automaker attributed the mix-up to a supplier’s coding-entry mistake. BYD said its own testing found no adverse effect on handling or driving safety, but apologized and promised remedies. Its statement did not disclose how many vehicles or production batches are affected.
The development turns earlier owner complaints into a manufacturer-acknowledged assembly fault. For buyers, the immediate issue is whether their specific vehicle is included and how a service appointment will be arranged. This concerns the Da Tang, also called the Great Tang, sold in China; it must not automatically be assumed to cover every vehicle marketed elsewhere under the Tang name.
On November 11, BYD responded publicly after owners complained that front and rear rims had been assembled in the wrong positions on some Da Tang EVs. The manufacturer said it had completed an investigation and identified an error by rim subassembly supplier Hubei Boyu Industrial Co., Ltd. in the way codes were entered. That mistake, it said, led to incorrect fitment on some vehicles. The account is supported by Reuters’ November 11 report and the company statement described in Yicai’s report of BYD’s statement.
BYD said it had started checking and correcting the codes used in production. It also said the supplier had introduced visual error-prevention checks on its production line. Those are the preventive steps the company reports having taken; there has not yet been an independently published assessment in the sources reviewed demonstrating that the measures eliminate every possibility of recurrence.
Earlier reporting had identified complaints involving the 2026 Da Tang EV 950-kilometer rear-wheel-drive version with 20-inch wheels. That is useful context, not a comprehensive list of affected trims or VINs. The statement itself referred to some Da Tang vehicles without releasing a precise affected-unit count. Shanghai Securities News’ reporting documented the emerging owner complaints before the manufacturer’s response.
The reported error concerned the wheel rims, rather than an announced defect in the electrical drivetrain or vehicle software. The 20-inch configuration discussed by owners uses different rim widths at the front and rear. Accounts of the affected vehicles described rims intended for the rear being mounted at the front, and vice versa, while tire positions were not similarly changed.
Owner descriptions cited a specified 8J-by-20 front rim with a 255/50R20 tire, and a 9J-by-20 rear rim with a 275/45R20 tire. The reported mix-up placed the wider 9J rim at the front and narrower 8J rim at the rear. These details describe the configuration highlighted in complaints; they should not be treated as a specification sheet for every Da Tang trim. A wheel that looks normal from the outside may still carry the wrong rim-width marking, which is why a qualified inspection matters.
BYD says no. Its November 11 statement said dedicated checks found the affected vehicles’ handling was unchanged and identified no driving safety risk. That is the manufacturer’s assessment, not a separately verified safety clearance for every car or an explanation of all test methods.
Some owner accounts raised worries about tire wear and vehicle behavior. Those are concerns and allegations, not proof that the rim swap caused a crash, blowout, or specific component damage. No substantiated incident total or independent technical findings establishing such outcomes were available in the materials reviewed. The practical response to an unexpected vibration, pull, tire bulge, pressure loss, or other abnormal behavior is to stop using the vehicle when safe and have it checked promptly, rather than rely on a general statement about the model.
BYD says it will invite affected owners to their local service centers for free vehicle inspections and professional correction of the rim installation. It also says affected customers will be offered a temporary replacement vehicle or reimbursement for transportation expenses. In its apology, BYD pledged that the whole-vehicle warranty period for incorrectly assembled cars would restart from November 11, 2026.
Those undertakings are important, but several implementation questions remain unanswered publicly: how owners will be identified, the precise VIN or build-date coverage, how quickly replacement appointments can be completed, and whether additional tires or components will be changed after individual inspection. Owners should request written confirmation of their car’s eligibility, the work performed, any tire or suspension findings, the applicable transportation provision, and the updated warranty terms. Do not assume that all vehicles receive new tires or that compensation amounts are uniform.
It would be inaccurate to describe the China announcement as a confirmed UK safety recall. The evidence reviewed documents a manufacturer-led remedy for some Da Tang vehicles, but does not establish a formally issued UK recall notice, a British affected-vehicle population, or a UK-wide campaign covering other BYD models.
That distinction matters because the Da Tang/Great Tang named in the announcement is a China-market flagship SUV, whereas BYD uses several different model names across international markets. The BYD UK’s model lineup is a better guide to current UK retail models than similarly named posts from another country. A UK driver who believes their vehicle has an issue should contact BYD UK customer support with their registration or VIN through the company’s official customer-service channel, and can use the UK government vehicle recall checker to check registered safety recalls by registration or make, model, and year.
A voluntary inspection or correction does not automatically mean that the regulator has issued a recall. Conversely, the absence of a recall listing is not proof that a particular car is mechanically sound. When there is uncertainty about the wheel fitment, a direct check against the vehicle’s approved specifications is more meaningful than a broad headline.
The next verifiable milestones would be BYD publishing a more detailed range of affected cars, explaining how all affected owners will be notified, and reporting the completion of inspections and corrections. Regulatory findings, if any are issued, could also clarify the safety classification. None of those future outcomes should be assumed in advance.
For now, the strongest established facts are the confirmed assembly mix-up, BYD’s account of the supplier data-entry error, and the company’s announced service and warranty response. The number of cars affected and any independent assessment of their long-term condition remain open questions. Readers should distinguish newly published manufacturer or regulator documents from social-media estimates when tracking this story.
The manufacturer announcement concerns some BYD Da Tang (Great Tang) electric SUVs in China. Owner reports particularly discuss a 20-inch-wheel rear-wheel-drive configuration, but BYD has not published a complete affected-VIN list in the material reviewed.
BYD has promised free inspection and professional rim correction for affected vehicles, along with replacement transportation or travel-cost assistance. Owners should confirm the precise repair and warranty details with their authorized service center.
No specific UK recall for the Da Tang rim mix-up was verified in this review. UK owners should check UK government vehicle recall checker and ask BYD UK customer support about their own vehicle rather than assuming that a China-market service action applies to them.
