The Chinese arm of German luxury automaker BMW is recalling 179,527 vehicles in the country after regulators identified a wiring flaw in the front-cabin air conditioning system that could damage the harness during routine maintenance and, in extreme cases, spark a short circuit and fire.
China’s State Administration for Market Regulation (SAMR) announced the voluntary recall on Tuesday, describing it as an immediate action covering both locally produced and imported models.
The vast majority — 133,849 units — are domestically manufactured 5 Series sedans built by the BMW Brilliance joint venture between December 5, 2023, and April 12, 2025. The remaining 45,678 vehicles are imports: 8,978 5 Series (produced October 17, 2023–April 8, 2025), 36,527 7 Series (June 9, 2022–April 3, 2025), and 173 M5 performance sedans (July 4, 2024–April 2, 2025).
The defect is straightforward but potentially serious. SAMR said the air-conditioning wiring harness in the front cabin was improperly routed at the factory. When technicians replace the cabin air filter — a standard after-sales service performed at dealerships or independent workshops — the harness can be snagged or pinched. Over time, repeated contact may fray the insulation, raising the risk of an electrical short circuit and fire.
BMW Brilliance Automotive Ltd. and BMW (China) Automotive Trading Ltd. will remedy the problem at no cost to owners. Dealers will inspect the harness, re-secure it with improved routing or retaining fixtures, and replace it if any damage is found.
Vehicles that have already undergone a related repair under earlier service campaigns will not require further work. Owners will be notified by registered mail, messages through the ConnectedDrive system, and the My BMW app. They can also check their vehicle status via the app’s customer service or by calling the national hotline 400-800-6666.
The action comes as BMW continues to navigate quality concerns in its single largest global market. China accounted for roughly one-third of the company’s worldwide sales last year, and the locally built 5 Series remains a bestseller among affluent urban buyers.
The recall follows several other recent campaigns, including one last November involving thousands of electric vehicles over a high-voltage software glitch and an earlier starter-motor fire-risk action that affected more than 147,000 cars.
A similar air-conditioning harness issue prompted a separate recall of roughly 58,700 vehicles in the United States in February, though those involved different model-year batches and were limited to certain 5 Series, 7 Series, i5, i7, and M5 variants.
In that case, BMW described the problem as a packaging issue uncovered during quality checks and stressed that no accidents or injuries had been reported.
No injuries or fires linked to the China-specific defect have been publicly disclosed by regulators or the company. Still, authorities urged owners of the affected vehicles to schedule an appointment promptly rather than wait for the official notice. “Safety recalls of this scale underscore the importance of routine maintenance being performed only at authorized centers,” one industry analyst noted, though BMW itself has not yet issued a detailed public comment beyond the regulatory filing.
For BMW, the episode is another reminder of the intense scrutiny luxury brands face in China, where consumers expect German engineering precision and regulators move swiftly on any hint of safety risk. The company has pledged full cooperation with SAMR and said the fix is simple and effective.
Owners are advised to monitor their dashboards for any unusual AC-related warning lights and to avoid DIY filter changes until the recall work is completed.
WHAT YOU SHOULD KNOW
BMW China is recalling nearly 180,000 vehicles (mainly 5 Series and 7 Series models) because of a simple but serious wiring fault in the front air-conditioning unit.
During routine cabin air filter replacement, the wiring harness can be damaged, raising the real risk of an electrical short circuit and fire.
Owners of affected cars should book a free inspection and repair at an authorised BMW dealer as soon as possible.
