2025 Volvo EX90 Electrical Problems

Mileage when the problem started

Owner reports

Selected complaints filed with NHTSA by 2025 Volvo EX90 owners, lightly cleaned up (personal details are redacted by NHTSA).

The contact owns a 2025 Volvo EX90. The contact stated that while the vehicle was parked, an over-the-air software update was attempted but failed. The vehicle locked during the update process and remained inoperable for approximately one hour after the update was completed. On a separate occasion, the vehicle failed to shift into gear while driving on the interstate. The message that the vehicle was not in gear was displayed. The download process took an extended period and after the update was completed the vehicle operated as intended. Additionally, the infotainment system turned black and was inoperable, while the instrument panel was dark, and caused the turn signal indicator and speedometer to become inoperable. The instrument panel was flashing. The vehicle was taken to the dealer where it was determined that the battery was in low power mode. …

The contact owns a 2025 Volvo EX90. The contact stated that while using the house charger, the breaker tripped. The check connection message was displayed. The vehicle failed to charge at the residence. The vehicle was later taken to the local dealer, who was unable to charge the vehicle. The contact eventually used a standalone charging system to charge the vehicle. The vehicle was taken to another local dealer, Subaru of Melbourne Service Center (4340 W New Haven Ave, Melbourne, FL 32904); where it was diagnosed and determined that an unknown part needed to be replaced; however, the part was on backorder. The vehicle was repaired, but the failure recurred. The manufacturer was contacted, and a case was opened. The failure mileage was approximately 80.

I was parked in a parking lot and when I released my foot from the break, the car accelerated on its own and crashed into the car in front of me. The automatic emergency braking did not deploy. It was most recently a safety risk and put others in the parking lot, particularly the driver in front me, in danger. I have reported this issue to Volvo and they instructed me to get the body of the car repaired and then the dealer will inspect it. I filed an insurance claim with my insurance company and the car is going to be repaired. There were no warning lamps or messages prior to the failure.

Please note this is an all electric SUV. On Saturday 6th December, I unplugged the car from the A/C charger after it had finished charging to 90% in my garage and there was a very loud bang heard from under the car. The dashboard then reported there is a fault with the car and it cannot charge. Took the car to the dealer same day and they suspected it was a failed GHCA part (AC to DC converter). They ordered a replacement and fitted it on 20th December but the car still will not charge on A/C. It still charges on DC and the dealer is using that to keep it powered. I received a call from the dealer today (1/2/26) to say that Volvo corporate needs to perform a detailed investigation as to what has caused the car to stop charging on AC. The dealer will not let me have the car back as they are concerned about the safety of the car and have been without it for approaching one month now. …

The vehicle has experienced repeated intermittent electrical-system-related failures since the start of the lease, which have remained unresolved despite eight months of formal engagement with Volvo and multiple service and software-related repair attempts by Volvo. Most recently, on May 15, 2026, while operating the vehicle in approximately 90 F Arizona temperatures, the vehicle displayed a "Limited Performance / Electrical System Temporarily Limited" warning message. Shortly afterward, the driver was temporarily unable to re-enter the vehicle, despite the exterior door handles deploying normally. Vehicle access was restored only after several minutes. The side view mirrors would not open. Driving for two minutes did not resolve this. After ten minutes of remaining parked the mirrors reconnected. …

Vehicle: 2024 Volvo EX90 VIN: [redacted] While driving on the highway, the entire digital instrument cluster and infotainment screen went completely black without warning. I could not see my speed, gear indicator, or use turn signals. This created an immediate and dangerous safety hazard, especially at high speed. The issue has occurred more than once, and despite taking the vehicle to the dealership, it has not been permanently resolved. I have filed a California Lemon Law claim with Volvo, and while Volvo acknowledged the defect and promised a buyback on March 18, 2025, they have failed to follow through or provide a resolution for over two weeks. I am submitting this complaint because the vehicle presents an active safety risk to myself and others, and I am concerned that this defect could result in a serious accident or injury if not addressed immediately. …

On September 3rd 2026, my wife was driving our 2025 Volvo EX90 Ultra (approx.1560 miles) with our three children, ages 1, 4, and 6, in the vehicle when the air conditioning failed completely. Outside temperatures were over 100 F in Austin, Texas. The EX90 has a large glass panoramic roof, and the cabin heated rapidly once the AC stopped cooling. This created an extremely dangerous situation for young children. Along with the AC failure, the vehicle made a rumbling noise every 5-10 seconds and its charging was limited. Because these symptoms occurred together, I am concerned the fault may involve the vehicle's thermal management system, which could affect the high-voltage battery as well as cabin cooling. The vehicle has been at an authorized Volvo dealer, for approximately two weeks. …

While driving on I-5 north by Castaic (exit 176A) the car displayed "electric system temporarily limited" then "critical electric fault" at which time it rapidly decelerated while on the freeway. The hazard lights were pressed but did not work. There was no shoulder and cars nearly rear ended our vehicle, with our family of 4 (including 2 kids) inside. We were able to navigate the vehicle to a small shoulder at the freeway exit and called CHP for support to ensure our safety while we seemed roadside assistance. Volvo roadside assistance contacted a tow truck and walked us through a "hard reset" of the vehicle. After about 15 minutes we were able to drive the car with a CHP escort off the freeway ramp to a nearby parking lot. The "electrical system temporarily limited" fault remained. Our car was towed to the nearest dealership where the fault was observed. …

While driving the car on a state road (45 mph) the car suddenly notified me of an "electrical fault", a light that looks like a turtle came on, and the vehicle lost power and couldn't go any faster than 5 mph. Another vehicle almost rear-ended me around a blind curve because I was moving significantly slower than normal traffic. I pulled into a parking lot, shutdown and restarted the car and everything seemed fine. It happened again a few minutes later so we started to head back home. But the real issue happened a minute or so after the second fault - the fault cleared itself and all of a sudden the vehicle's speed shot up to over 60 mph with very little throttle response or control from me. I slowed the car down using the brakes and continued home. …

My husband and I were driving with our [redacted] son on the southbound [redacted] in the fast lane. There was some traffic so we were not traveling too fast, but in the fast lane nonetheless. An error message came on the screens indicating there was a critical electrical failure. At that moment, my husband realized that the car's acceleration was no longer working. We went to turn on our hazard lights and those did not work either (as they are solely in the computer panel and not a separate mechanical button). Thankfully we were able to safely make our way to the side of the highway to wait for a tow truck. The car was towed to Galpin motors, and has been there ever since. As of today, we have been told the issue is with the VCU (hardware and software) and is on indefinite back order. Previously we had to have the entire TCAM module replaced twice on this same car.
