(Bloomberg) — It took Tesla Inc. about 15 years to rack up $5 billion in losses. The company known as China’s Tesla did it in four.

The bleeding continues. Shanghai-based NIO Inc. is poised to report Tuesday that it lost another 2.6 billion yuan ($369 million) — around $4 million a day — during the second quarter, according to the average of two analyst estimates. That would bring accumulated losses at the company, which is backed by technology giant Tencent Holdings Ltd., to about $5.7 billion since William Li founded the carmaker in 2014.

Cost overruns, weak sales, and major recalls have led NIO to plunge 74% since its market value hit a record $11.9 billion about a year ago. More broadly, the company’s reversal of fortune illustrates why concerns are mounting that China created an electric-vehicle bubble that may be about to burst.

“This year and the next, there’s going to be a lot of card-shuffling for these EV startups,” said Siyi Mi, an analyst at BloombergNEF. “Before, venture capital chased after them, but it’s not the case anymore.”

Total EV sales in China, where half of the world’s electric cars are sold, fell for the first time in July after the government scaled back subsidies. Deliveries dropped again in August, raising doubts that one of the final pillars of strength in China’s broader auto market, which has fallen 14 out of the past 15 months, is wavering.

China has dialed down subsidies for new-energy vehicles — all-electric, fuel-celled autos and plugin hybrids — since 2017 to help the industry stand on its own two feet and avoid a bubble. That’s undermined growth, prompting the likes of top Chinese electric-carmaker BYD Co. to warn recently that earnings will wane.

At NIO, pressure is building for it to raise more funds. The carmaker is seeking to reduce its workforce by 14% to 7,500 by the end of the month, according to the company. Incidents involving batteries catching fire or spewing smoke forced NIO to recall about 4,800 vehicles — more than 20% of all the cars it’s ever sold. Second-quarter deliveries dropped from the preceding three-month period.

The company also scrapped plans for a manufacturing plant in Shanghai after the government opted to provide financial support to Tesla. Instead, NIO farms out production of its ES6 and ES8 cars to Anhui Jianghuai Automobile Group Co.
