2021 Volvo XC90 Engine Problems

“My 2021 Volvo XC90 Recharge has experienced multiple hybrid system failures under Volvo's factory 8-year/100,000-mile hybrid warranty, with fewer than 45,000 miles on the odometer. The high-voltage battery modules have failed multiple times, directly related to recall R10312 (NHTSA 25V-179), which identifies a supplier process deviation in LG battery modules creating a risk of internal short circuit and thermal runaway — an acknowledged fire risk. Critically, my vehicle has suffered two actual battery module failures, not preemptive recall replacements. …”

“Unintentional acceleration.First, I was in line at car wash proceeding slowly ahead as directed in line. Foot on accelerator lightly moving, when car surged rapidly hitting back end of Tesla about 6-8 ft ahead (2/26/26 12:30pm) Impact strong enough to push Tesla into truck hitch damaging it front of it as well.

Made right turn on green light and started to accelerate when it revived and surged forward until applied brake. Dealer could not replicate. …”

“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.

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. …”

“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. …”

“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. …”
