2024 Volvo XC40

Right when I turned the car on, a million different alarms went off saying different systems weren’t available. Then I started driving, and it accelerated normally, but when I took foot off accelerator: it didn’t slow down. This was really noticeable because I had one pedal drive on, which means taking foot off the gas acts as a very light brake. I could slow down with the brake, but then as soon as I took my foot off the gas, it would speed back up. Really weird feeling: it was like the cruise control had set itself and it was taking me back to that speed. But braking worked, so I could stop and control the car with just the regular brake. But then when I came to a full stop, it just locked up: parking brake on and wouldn’t come off. I just basically kept trying things to get it going again and it finally did. But then it happened again, where it would accelerate on its own and I had to control the car with just the brake. I had the car towed for repair the next day, and the tow truck driver said he noticed it accelerating on its own as he drove it up onto the truck. Volvo maintenance also confirmed the problem. They had the car forever and ultimately decided it was a problem with my “external audio module”.

Randomly, the sound from the infotainment system stops working. This impacts the turn signal sound inside the car, the cross traffic alert sound, blind spot warning sounds, etc. This can be fixed by restarting the infotainment center, but this is not safe to do while driving. Being unable to hear the turn signal increases the chance of forgetting to turn it off, causing confusion for other drivers. This issue has not been confirmed by the dealer or manufacturer, although other infotainment issues have been acknowledged. The failure is random, with no indication before hand.

passenger side map light keeps activating. It will not shut off via touch controls. only cycling the dome light manually (not by opening a door) tends to rectify the problem. Shutting off and restarting the vehicle does not work. It's particularly distracting at night for both driver and nearby traffic. Repeated trips to service deny the activity, although it is discussed heavily on discussion boards and forums, particularly centering on recalls of the infotainment head unit (which the dealer also denied there was a recall despite notices and even carfax reports).

Brake system failed. I was NOT in one pedal mode. I have up to date software. After break system failed I was unable to put vehicle in park. Parking break could not be applied. Could not turn car off or lock doors. I was driving on interstate when it occurred. I got multiple warnings on display. I was lucky to pull over and not crash.

The contact owned a 2024 Volvo XC40. The contact stated that his wife was entering a parking lot at approximately 10 MPH when she heard the vehicle engine abnormally revving and the vehicle independently accelerated. The vehicle drove through the parking lot and crashed into a tree. The contact stated that the driver's and passenger front air bags deployed, and the front collision avoidance had not engaged. The contact stated that the vehicle crashed into the tree almost at the center of the front bumper and grill. The hood had been crushed, the grill cracked, and the bumper had been torn off. The contact stated that the police arrived on scene but did not write a report since no other vehicles were involved. The contact stated that his wife had scrapes and bruises on both arms and scrapes on her nose and forehead. The wife was not attended to by EMT, but later went to the ER for neck and back pain. The vehicle was towed to an impound lot and later declared a total loss by the contact's insurance provider. The contact had contacted the manufacturer, who sent a technician to download information from the vehicle computers. The contact stated that a summary was released by the manufacturer that indicated that the crash was a driver error. The failure mileage was approximately 8,000.

On two separate occasions, brakes failed completely in snow. Vehicle did not appear to be hydroplaning, and anti-lock function did not kick-in despite the pedal being floored. Pumping had no effect either. Safety sensors around the car should have detected motion even if the wheels were locked-up and should initiate anti-lock procedures as well. Distance traveled (at low speed due to snow and heavy traffic) was well over 100 feet. Emergency stopping feature finally engaged anti-lock brakes about 1/2 second before impact. To avoid a second crash (someone two vehicles ahead caused a pileup) a year later, driver had the wherewithal (and space) to leave the roadway when brakes failed to even slow the vehicle.

The contact owns a 2024 Volvo XC40. The contact stated while in reverse (R) and backing up at approximately 2 MPH, the vehicle rear view camera proximity warning lights had failed. The contact described the proximity warning as dots that show a visual progression of how close the rear bumper was to objects, yellow, orange, and red. The contact stated that the red dot signaled to stop the vehicle. The contact stated that the colored dots had been working as she was adjusting the vehicle to allow her to open the trunk, however when she had again shifted to reverse (R) to park the vehicle, the warning dots had disappeared from the display panel, and the contact crashed into some shelving located behind the vehicle. The contact stated that a shelf at the level of the rear windshield had shattered the windshield. The contact had not yet taken the vehicle to a glass shop or to a dealer. The contact stated that she had only called the dealer for information and was advised to bring the vehicle to the dealer's repair shop. The vehicle was not repaired. The manufacturer was not informed of the failure. The contact reported that in 2025, she had had a recall, NHTSA Campaign Number: 25V282000 (Back Over Prevention), completed, but was not sure if the current failure was related. The failure mileage was approximately 12,000.
