Multiple Xpeng X9 owners report recurring air suspension failures, raising questions about reliability and safety amid extreme temperatures.
Xpeng’s flagship multi-purpose vehicle (MPV), the Xpeng X9, has come under increasing scrutiny after several owners reported recurring air suspension failures, with some incidents allegedly linked to extreme temperatures in China’s Chongqing region.
The complaints have triggered concerns about vehicle safety and reliability, particularly as some drivers experienced sudden suspension malfunctions while on the road.
According to reports, affected vehicles suffered air leaks within the suspension system, causing the chassis to drop unexpectedly on one side or, in some cases, collapse entirely. Owners claim these incidents occurred during a recent heatwave, raising questions about the vehicle’s ability to perform under challenging weather conditions.
Responding to customer inquiries, Xpeng’s customer service team stated that the X9’s air suspension system may activate a “thermal protection” mode in high-temperature environments.
The company explained that frequent manual or automatic height adjustments while driving could cause the suspension compressor to overheat. When this occurs, drivers may receive a warning indicating that the compressor has overheated and can no longer adjust the suspension.
The automaker advised drivers to stop in a safe location and allow the compressor to cool down, noting that the system typically resumes normal operation after some time. However, Xpeng has not yet provided a detailed explanation regarding reports of air leaks or incidents involving chassis collapse.
Customer complaints suggest the issue may be more widespread than initially believed. Information published on the automotive quality complaint platform 12365auto revealed that one Xpeng X9 EREV Max owner experienced air suspension failures at just 1,552 kilometers. The problem reportedly reappeared at 2,500 kilometers, and inspections later identified a motor inverter short circuit and a blown fuse.
The owner expressed dissatisfaction over repeated repair visits within just five months of ownership and claimed the service center declined to formally acknowledge the fault inspection report. Similar complaints have also surfaced on social media, where Xpeng owners have discussed recurring suspension failures in large online communities.
The controversy comes after Xpeng’s P7+ sedan faced steering system issues last year, eventually resulting in a recall of approximately 48,000 vehicles. Despite mounting complaints, Xpeng has yet to release an official investigation report or announce a comprehensive solution for affected X9 owners.
Launched in January 2024, the Xpeng X9 is marketed as an advanced seven-seat MPV and has achieved cumulative sales of 13,324 units during the first half of 2026. However, the growing number of suspension-related complaints could present a significant challenge for the brand as it seeks to strengthen consumer confidence in its premium vehicle lineup.
