XPeng X9 owners in Chongqing have reported air-suspension faults that left some vehicles sitting low on one side or across the body during a spell of hot weather.
Jinzhao News, citing Chongqing City TV, said several owners experienced the problem while driving. Some vehicles had been parked in underground car parks during the day before being taken onto the road in the afternoon.
Owners described air loss from the suspension, followed by a partial or complete drop in ride height that prevented normal driving. They suspected the high temperatures, although no published technical investigation has established heat as the cause.
According to Jinzhao News, XPeng customer service said frequent suspension adjustments in hot weather could cause the compressor to enter thermal-protection mode.
The vehicle may then display a warning that the compressor is too hot to adjust the suspension. Drivers were advised to stop safely and allow it to cool.
The system would generally resume normal operation after some time, while persistent faults should be inspected at a service centre.
That explanation covered compressor overheating but did not address owners’ accounts of air leaks or vehicles dropping on one side or across the body.
Customer service also said the X9 could adjust its ride height automatically while moving, meaning compressor use was not controlled entirely by the driver.
XPeng did not disclose the temperature at which protection mode is activated, the number of complaints received or whether the Chongqing cases shared a common fault.
Jinzhao News also cited an owner of an extended-range X9 Max who reported an air-suspension failure at 1,552km. The same problem allegedly returned at 2,500km following repairs.
An inspection reportedly found a motor-inverter short circuit and a blown fuse. The owner claimed the service outlet refused to sign the inspection sheet and said the five-month-old vehicle had been returned repeatedly for repairs.
No connection between that case and hot weather was established.
Similar claims appeared in July 2025, when a social-media post alleged that dozens of members in an X9 owners’ group of more than 100 people had experienced suspension collapse.
XPeng had not released a public investigation report or general repair plan when the Jinzhao News article was published.
The X9 went on sale in China in January 2024 and is now offered with battery-electric and extended-range powertrains.
XPeng delivered 16,859 X9s during the first half of 2026, including 2,584 in June, according to China Passenger Car Association data compiled by CnEVPost.
