Volvo EX90 Electrical problems by year

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 NHTSA investigate the recurring electrical failures that have zero mechanical or safe manual override

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.

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.

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.

occurred previously. Because of the unexpected loss of propulsion at freeway speed, I no longer considered the vehicle safe to drive. The vehicle was subsequently transported by flatbed tow truck to an authorized Volvo dealership for diagnostic inspection. The dealership is working with Volvo technical support to diagnose the incident. I also reported the incident directly to Volvo Customer Care and requested escalation. At the time of the incident, the vehicle had approximately 1,531 miles. There was no crash, fire, injury, or fatality. I am concerned that an unexpected loss of propulsion at freeway speed could result in a collision if the failure occurs in heavy or high-speed traffic. I am reporting the incident so NHTSA can evaluate whether similar propulsion, electrical, charging-system, or software-related failures have occurred in other Volvo EX90 vehicles.

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.

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.

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.

approximately 578 miles when the vehicle stopped charging. Volvo attempted repairs, but the same charging defect returned. The vehicle required additional repairs on January 21, 2026 (1,304 miles), early March 2026 (2,846 miles), and April 27, 2026 (3,810 miles). Despite multiple repairs and component replacements, the same issue continued. By the fourth repair, the vehicle had been out of service approximately 80 days. Volvo later approved a manufacturer repurchase; however, while waiting for the repurchase process, the vehicle developed additional failures where it would completely lose power and become inoperable. The vehicle required towing on multiple occasions, leaving me stranded and without transportation. During a later repair visit, Volvo kept the vehicle for approximately 39 days and stated they could not duplicate the problem and that the vehicle was operating as designed. The day after receiving the vehicle back, the same failure occurred again. The vehicle has now required seven repair attempts. Even after the latest repair, I continue to receive dashboard warnings while driving instructing me to stop the vehicle. Due to the repeated failures, loss of vehicle operation, and unresolved warnings, I have lost confidence in the safety and reliability of this vehicle and have changed my driving habits to avoid being stranded. I believe these recurring failures represent a potential safety defect that warrants investigation by NHTSA.
