Abstract:
According to Jiemian News, the Tesla Model Y L, which has been on the market for just over a year, is facing intensive complaints from car owners about the car's rear end sinking.
Many car owners have reported that the gap between the rear wheel and the wheel arch has shrunk from more than four fingers when picking up the car to three or even two fingers. There are still cases of recurrence after replacing the springs. Tesla has not initiated a recall or publicly responded.
It is reported that Model Y L will be launched in China in August 2025, with a starting price of 339,000 yuan. It is the first time Tesla has launched a six-seater version of Model Y. The car was developed by a Chinese team.
According to data from China Automotive Data Research, the cumulative sales of Model Y L in China from January to July 2026 was about 36,000 units. A communication group for the rear wheel collapse problem voluntarily formed by a car owner currently has about 300 members. The basic solutions given in the group are to replace the rear suspension springs.
The symptoms described by car owners are highly consistent. The gap between the rear wheel and the wheel eyebrow continues to shrink, accompanied by hardening of the shock absorber, bottoming out over potholes, and the body shakes or deviates.
After driving about 33,000 kilometers, a car owner in Nanjing found that the height of the rear wheels was significantly lower than that of the show car, and the children in the second row were obviously thrown when passing the speed bump. A Zhengzhou car owner noticed a sinking trend after driving about 8,000 kilometers.
When a Hangzhou car owner purchased the car, he was told that the new car had been replaced with B-type springs and would not sink easily. However, after driving for more than 30,000 kilometers, "it was difficult to put a finger in".
Two chassis engineers believe that irreversible plastic deformation of the spring is the main cause of the collapse of the rear wheel.
One of them pointed out that the six-seat Model Y L design makes the rear axle load heavier than that of the four-seat Model Y. If the same spring specifications are used, long-term overload conditions will accelerate fatigue decline. "Just replacing the supplier's springs does not solve the fundamental problem." He judged that Tesla should have started the internal design change verification process, and the recall would be possible only after a solution was found.
In addition,
Another car owner said that he had the spring replaced at the end of April, but it sank significantly again at the end of August.
When entering the store for the second time, the service center did not replace the spring, but disassembled the coil spring to "relieve the stress", and the work order no longer reflected the specific height value.In response to this matter, the media asked Tesla about the reason and whether it would recall it, but received no response.
