Volvo XC90 purchasers have complained of various problems including check engine light.

1. NHTSA Complaints

Here are some typical complaints

The compressor (or another component controlling the HVAC system in the 2018 XC90) failed while driving. The heat inside the vehicle quickly raised.  In October 2018, I again, finally, took the 2018 XC90 to the service department because (1) the check engine light came on; and (2) the electronic safety systems, such as the auto braking, had automatically engaged without any cars around the vehicle. The vehicle was also driving and handling in a strange manner.
