2021 Volvo XC40 Electrical System Problems

Back up camera consistently does not turn off. Audio system, including turning signals and reverse alert do not activate. This continues to be a safety risk despite numerous software updates that have allegedly fixed the issues.

1. OBC failure. Stranded unable to charge. Situational could be dangerous. 2. Rt side mirror defaults to extreme angle after locking car evert time. Dealership could not troubleshoot solution.

Turning out of parking lot , car started pulsing, and stopped. Propulsion failure box popped up. Thankfully no cars behind us (young daughter in car seat)or was not attempting to merge on highway. Tow truck manually pulled car as no electric (cannot unlock or open trunk), completely shut down.

The 12-volt battery has failed on 5 occasions. Each time, I tried to unlock the vehicle after being away from it for a short period (e.g., 5-40 minutes). I had to use the manual key to unlock the vehicle, but the vehicle wouldn't start. I had the vehicle towed 4 times. One time it started on its own. I have taken the vehicle to my Volvo dealership 3 times for this issue. The most recent time this happened the dealership instructed me to have Volvo Roadside Assistance tow the vehicle to the dealership, even though the vehicle was 91 miles from the dealership. The tow operator confirmed to me that the car wouldn't operate, and that she reported this to the dealership. Still, because the dealership has be unable to replicate the problem, it refuses to replace the 12-volt battery system. There have been no warning lights. This is a safety issue because it has occurred at night, far from my home and outside of mobile phone coverage. I am also concerned that it may occur while I am driving, although that has not occurred.

The check engine light has been on my vehicle since April 1, 2024. I have taken it in twice to a Volvo dealership and they cannot give me an answer as to why this is happening. They reset it and it comes right back on after a few miles. They tell me when they get an answer they will call me back in to have it fixed. It still has not been fixed.

The contact owns a 2021 Volvo XC40. The contact stated that at a stop light, the vehicle became inoperable. The contact stated that the doors would not unlock, and the seat belts became inoperable. The Rear Collision Avoidance warning light was illuminated. The contact stated that the warning light remained illuminated without another vehicle being behind. The vehicle was towed to a dealer. The vehicle had not been diagnosed or repaired by an independent mechanic or dealer. The manufacturer was made aware of the failure and confirmed that the VIN was not included in a recall. The failure mileage was approximately 58,000.

I was driving our vehicle on the highway and proceeded to exit on the ramp. As I was decelerating, the instrumentation started making electrical noises and then the center console and the entire navigation screen went black. They flickered then came back up briefly before shutting off a second time, then the entire car shut down. There was no power to anything. I then attempted to push the start button, and the car did not start the first time. I tried pushing the button a second time and the car started. I brough the car to the Volvo Dealership where we purchased the vehicle and they said the car was due for a major software upgrade. I thought this was ridiculous, but said ok. After a few hours, they said the car was completed and let me take it. I did not get 100 feet down the road and noticed my moon roof no longer worked. I brought the car right back, and the technicians got in my vehicle with me in it and attempted to re-calibrate the moon roof with no luck. It was at this point they gave me a courtesy vehicle and kept my car over the weekend until Monday afternoon when they called to sday they were finally able to re-calibrate. I am extrememly concerned about this incident, and did not like how the dealership brushed it off as normal! This is a serious issue, thank God my wife was not on the hoghway when the car shut down!!

On October 12, 2021 the above described car had a catastrophic failure of the power system. All functions ceased and the car was dead towed on a flatbed truck. Because the tow mode could not be engaged due to loss of all power the vehicle was dragged onto the flatbed. The repair indicated the cause was a The Battery Energy Control Module (BECM). This is noted in recall R10078. This car was sent for service in April where a request for a software update was made. At that service, no recall was noted and no update was given for this condition. There has been no attempt to recall this vehicle for this problem and it is not noted as a recall for this vehicle. The failure of the energy module caused a complete loss of all power and an inability to move the car.

The 2021 XC 40 vehicle will periodically not restart - may be something to do with the safety key or some other electrical malfunction. The dashboard shows the battery symbol when the car will not restart as if the vehicle is dead (no electrical connection). Also, when the start button is depressed the dashboard illuminates with the dead battery signal, but otherwise, it seems the button is not connected to the vehicle in that the engine does not respond. Also, we had an issue where the vehicle, while we were beginning to stop at a stop sign, went dead and was not responsive. The “Start/Stop” function, although engaged in the center console, is often not operational and will show in the dashboard that it is not operational, but then, randomly (not consistent with the reasons itemized in the Volvo manual for why the start/stop function may not work), will work on a few stops for that particular drive and then revert back to not being operational on the next trip, although it is engaged to be “on” in the center console. Again, this appears to be a sign or symptom of some sort of electrical malfunction. Now, most recently, my wife and daughter were driving the vehicle, and it lost power and shut off in the middle of the road, horrifying these two individuals and greatly upsetting me that a vehicle sold by Volvo would perform so poorly and create a significant hazard to driver and passengers of the vehicle (not to mention others on the roadway). Again, and clearly, there appears to be some sort of electrical malfunction. Clearly, what we first reported to Volvo on or about May 17, 2021 was an electrical problem that Volvo had an idea or knowledge (knew or should have known) that was or may be similar to the problem they had already issued a recall for on the XC 40 recharge.

I WAS GIVEN THE CAR A A DEMO PENDING DELIVERY AND IT STOPPED UNEXPECTEDLY WHILE DRIVING NEARLY CAUSING AN ACCIDENT.
