One problem related to suspension noise has been reported for the 2021 Subaru Crosstrek. The most recently reported issues are listed below.
On 11/30/2020 I purchased a brand new Subaru Crosstrek from sheehy Subaru in springfield, virginia. It had 15 miles on the odometer. On 12/01/2020 it was delivered to me at my residence in washington, DC. I immediately noticed that there was a loud creaking noise coming from the rear of the car whenever I took a turn or went over a small bump in the road, including speed bumps. Within 30 minutes of taking possession of the vehicle, I contacted the dealership to notify them that I was concerned about the noise. They dismissed the noise as a regular part of the "new vehicle break-in process" and claimed that it would go away quickly. After driving the vehicle for approximately 10 more miles to see if the noise disappeared, I became concerned about my safety because the noise only appeared to be increasing, so I stopped using the vehicle. On 12/05/20, the first day possible, I took the car back to the dealership for service. The service department quickly confirmed that something was wrong with the suspension of the car, but they were not sure exactly what. They indicated it was a manufacturing defect. They said that they would look into it. It is now 12/08/20 and the car is still not repaired. So, in short, a new car with 15 miles on the odometer when I purchased it has now spent an equal amount of time in my possession as it has spent in the shop for repairs to the suspension. I worry that this issue is not limited to my vehicle alone as it is an admitted manufacturing defect that apparently cannot be repaired quickly.
