There are 3 owner-reported suspension complaints for the 2021 Polestar Polestar 2in NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
1 - The rear axles have failed. 2- A rear axle failure while driving presents extreme safety hazards, including sudden loss of vehicle control and stability, potential wheel separation, and abrupt loss of drive power, greatly increasing the risk of a severe accident 3 - Polestar has created a report on 3/4/24 regarding the issue AND IS AWARE OF IT - Technical Journal 36854.1.0 - Ticking noise during deceleration at Low Speeds. My car is 2 months out of Warranty and is a 2021 model and has 48,000 miles and they refuse to cover the cost of the repair Polestar owners have confirmed this online in various Polestar forums. 4- The Polestar dealer inspected it. 5- No warnings
There is a TBS out for a strut mount bearing replacement that causes clunking/rattling of the front suspension while driving on slight rougher roads or while turning left or right. However, this TSB does not solve the issue. Polestar claims they have an updated component/strut mount bearing that solves the clunking issue but it does not. My vehicle has the latest components installed under warranty (due to my vehicle exhibiting this issue) and it has not solved the suspension clunking. At this point, it is safe to say that the strut mount bearings are not the main or only cause of the front suspension clunking. There are other components involved that may be failing or have failed but have not been properly identified by the service centers or Polestar. Polestar does not seem to want to address this issue head on. In their own TSB, their wording is clear that they wish to delay the process of updating components so as to prevent buy backs during warranty periods. It's written in black and white and this seems highly irregular or illegal to have such a business model. We do not know if this issue poses a safety hazard or not but given it's a front suspension issue, it's only a matter of time before a vehicle loses control due to component failure that was not looked into or was not anticipated beyond the strut mount bearings. Please do something to solve this problem. This vehicle (Polestar 2) has been out now for FIVE YEARS and this issue has yet to be resolved.
While turning at moderate speed into a parking lot across traffic, a rear passenger side suspension component (potentially lower control arm) failed, causing excessive toe and camber on both sides of the rear axle as the components shifted around. At this point, the car stopped driving straight, and crabbed to the side aggressively. It seems to me that some suspension component is either at the design limit in this application and received enough stress to fail during normal operation, or a manufacturing defect wasn't caught and failed over time. My safety was put at risk as the rear wheel was no longer pointed in the direction of travel. Had this occurred at a higher speed (highway cloverleaf for example) complete loss of control of the vehicle would have been likely. Had this failure prevented me from entering the parking lot, I would have been left perpendicular to the flow of traffic and at high risk of collision with other drivers. The problem has been observed by the dealer service center, though they do not yet understand the cause. The components have been inspected by a service tech, but not by any manufacturer representative as far as I'm aware. There were no warnings or other presentation. When the tow driver struggled to drive the car onto the truck, he remarked in surprise that the car still showed no sign that it knew there was a problem. We were unable to get the car entirely onto the trailer, as it pushed sideways threatening to fall off of the ramps. The driver had to secure the vehicle to the ramps and take it like that.
