2021 VOLVO XC90 Engine Problems

The ERAD (Electric Rear Axle Drive) transmission on my 2021 XC90 T8 Recharge has suffered an internal failure at approximately 112,550 miles. The vehicle makes loud grinding and slamming noises from the rear drivetrain and locks up when attempting to drive, making the vehicle completely undrivable. The dealership (Volvo Cars Gilbert, AZ) diagnosed the ERAD clutch as slamming and suspects internal gears are missing teeth. A software update was attempted but did not resolve the mechanical failure. The ERAD transmission needs full replacement at a quoted cost of $5,211.56 (part number 32324105-9). This is a known failure point on the T8 platform and Volvo has redesigned this component (ERAD2) for newer models due to reliability issues with the original design. This failure presents a safety concern as the rear drivetrain can lock up unexpectedly during driving. This ERAD failure occurred alongside two other hybrid system component failures within a 3...

I plugged my usb to usb-c charging cable into my iphone 20 seconds after starting the vehicle. I proceeded to exit my driveway when the infotainment screen went completely blank and the same thing to the driver's display 10 seconds later. I drove to the end of my street to a stop light where the car completely shut off and automatically restarted within a few seconds. I was traveling with my wife and [XXX] daughter. I have yet to reproduce the problem but have an appointment scheduled with the dealership later this week. Zero warnings or messages were present before, during or after the incident.

On two separate occasions, while driving car on highway at high speed, the car has gone into a special shutdown mode, where a turtle icon lights up on the dash and the car begins to shut itself down rapidly, limiting maximum speed of vehicle to 35mph. There is no warning or advanced alert. Suddenly the car reduces speed and feels like it is dead, and the systems begin to alert you that they are going into a reduced function mode. This was extremely scary thing to happen at highway speeds with flowing traffic. I had to crawl to side of rose at very low speeds. I could have been injured. I took the car to dealer for service and they said it was a software issue. A few months after, this happened yet again, also while at highway speeds. I have read that others are having similar issues with the...

Vehicle is lurching on slow acceleration in Hybrid Mode. For example, lurching occurs when pulling away from a stop sign, pulling out into traffic, pulling into a parking spot. Issue started beginning of January 2023. In February Fields Volvo Service diagnosed issue as a software problem (Code IEM-P287100) and that Volvo hasn't written the software yet. Fields Volvo Service said software update should be available in Quarter 2. Advised that I do not drive my car in Hybrid Mode. I own a hybrid vehicle that I have been told not to drive in Hybrid. Unfortunately, Hybrid is the default mode so upon each start I have to manually change mode to AWD. There is also lurching in AWD on slow acceleration (not as bad as in Hybrid). On several occasions while driving in AWD the vehicle will spontaneously change the mode back to Hybrid resulting in decreased or no acceleration...
