While driving the car it gave a "Critical Electrical Failure" error message and slowed. It said to stop when safe. When stopped, it would no longer move. The screen was unresponsive. It could not be put into neutral so it could be pushed out of the way.

I am reporting repeated total electrical failures in my 2025 Volvo EX90 that create a serious safety concern, particularly regarding access to and escape from the vehicle. The vehicle has repeatedly become completely unresponsive, with the dashboard, headlights and interior lights dead. In the latest incident, this occurred approximately 15 minutes after parking at home. The alarm sounded for around 10 minutes before stopping, but the vehicle remained completely dead. The key fob, key card and Volvo app could not restore access. A roadside technician jump-started the vehicle through its 12V system, and it immediately woke up. The dealership had reportedly tested both 12V batteries and found them healthy. The most alarming issue is that the vehicle can be impossible to open from outside even when the doors are understood to be unlocked. If a child or another occupant were inside during a total electrical failure, someone outside might be unable to gain access to help them. We have young children who regularly travel in this vehicle. My wife’s phone was inside during an incident, and she could not access it. This creates a potentially life-threatening risk if a child is trapped inside during hot weather, a medical emergency, a fire, or another dangerous situation. I am also concerned about whether occupants can reliably exit during a complete power failure and whether an effective mechanical override is available for exterior entry. The vehicle spent approximately one month at the dealership for diagnosis but was returned without a confirmed root cause or lasting repair. The failure recurred on the same day I drove it home. Earlier, the dealership reported a loose ground cable contributing to a general electrical failure and performed software updates. The problem remains unresolved despite repeated contact with Volvo Customer Care (case 07229666). I request that the federal safety agency investigate the recurring electrical failures that have zero mechanical or safe manual override

My car is a Volvo EX90 and it is totally electric. Twice in the past 6 weeks the car has died, once I was driving and an electric and brake warning came on and told me to stop the car. I pulled over immediately and the car never worked again-- it would not turn on and it has been "bricked" for the past 21 days. I was in the middle of a 4 lane street which is very dangerous, luckily there was an entrance to a church where I pulled over because the car immediately died thereafter. If I would have been on the highway when this occurred I could have died. The first time the car "bricked" it failed to turn on in a parking garage after being parked for about 90 minutes. Volvo replaced the batteries after the first incident but they have been unable to tell us what is wrong with the vehicle now and the service department has had it for 21 days as of today.

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. The dealer replaced the AC compressor, but the problem is not resolved and they have not been able to diagnose the cause. Volvo customer care case number: 07200479. I understand other EX90 owners have reported similar AC failures. A total loss of cabin cooling in extreme heat is a safety hazard, particularly for families with children and in vehicles with large glass roofs.

Center screen goes black when driving. Driver display goes black when driving leaving me without speedometer or any data as everything is on those 2 screens. Misaligned passanger door that doesnt open properly. Dealership has fixed trim piece but not the alignment of the door. I have been back to the dealer several times - I bought the car XXX, it has spent at least 3 months in the shop. Volvo corporate on XXX said "At this time we do not have information on a permanent fix. Please rest assured that our technicians work on software updates to improve the infotainment center as well as the overall state of the vehicle. Once an update is available you will be notified with this information." The dealer (General manager) wrote me and said "We have done what Volvo recommends for the repair on this vehicle, unfortunately we have very few other options Have you opened a customer care case on this specific issue?" - I have 3 if not more customer care issues with Volvo. The dealer wont respond to messages, Volvo Corporate offers no help - they each say to contact the other these are well known issues with this car.

My husband and I were driving with our [XXX] son on the southbound [XXX] 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.

Failure of the onboard AC charging component, known as the Grid to High Voltage Converter A (GHCA) or onboard charger module. This vehicle would not charge on AC current, but could only be charged on DC current. This is a safety issue, as you may get stranded without access to a DC capable charger, since AC is the primary source for a majority of EV owners. Problem has been confirmed by the dealer. Volvo seems to be aware of the issue, as this is a common failure point according to other Volvo EX90 owners. Warnings that occur is a red illuminated light near the charge port when it is unable to accept a AC charge due to failure.

My 2026 Volvo EX90, with approximately 3,000 miles, experienced a complete vehicle failure while being used as our family vehicle in Phoenix, Arizona. While my nanny was driving my two young children, including my [XXX], the air conditioning stopped functioning during approximately 110–115°F outside temperatures. After she parked, the vehicle’s displays went dark and the vehicle became completely unresponsive. The exterior door handles also stopped functioning normally. My nanny was unable to open the rear doors from outside to remove the children and had to climb through the front seats into the rear passenger area in order to gain access and get them out of the vehicle. The vehicle would not respond to the key, would not restart, and did not respond to Volvo’s recommended reset procedures. Roadside assistance was required and the vehicle was towed to an authorized Volvo dealership. Several days later, the vehicle remains completely inoperable. The Volvo dealer has been unable to power the vehicle on, establish diagnostic communication with it, or open the doors normally. The vehicle is so immobilized that the dealership must place it on dollies simply to move it around the facility. This appears to involve substantially more than an infotainment failure. The incident involved simultaneous loss of climate control in extreme heat, complete vehicle shutdown, and loss of normal exterior door access while young children were passengers. I am particularly concerned about the potential safety implications if this failure were to occur again in extreme heat or in another situation where occupants needed to exit the vehicle quickly. The vehicle remains at the Volvo dealership for diagnosis, and no root cause has yet been identified.

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. The fault happened again, and cleared itself again in the same manner but this time while I was turning causing me to almost hit a curb while trying to turn. The car is dangerous. These should be taken off the road permanently.

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.
