This Problem Across All Years
The vehicle’s Start/Stop system began displaying warning messages and malfunctioning prior to the expiration of the factory warranty. The issue first appeared before 50,000 miles and reappeared at 49,997 miles, when a warning was displayed on the dashboard. The vehicle was taken to an authorized dealer for inspection. A diagnostic review confirmed the need to replace the Start/Stop auxiliary battery and repair the Park Assist system. A diagnostic fee was charged, and both system failures were documented. The Start/Stop system’s failure raises a potential safety concern because the vehicle may not reliably restart after automatically stopping at intersections or in traffic. This could lead to dangerous situations if the vehicle stalls unexpectedly or fails to re-engage power at a critical moment. Although the issue has not caused a crash or injury, it introduces unpredictable behavior that could compromise safe operation. The Park Assist system also failed, triggering system warnings and disabling parking assistance features. If a driver is relying on these systems during low-speed maneuvers, a sudden or silent failure may increase the risk of collision with objects, pedestrians, or other vehicles. The dealership confirmed the problem through inspection and diagnostic testing. The manufacturer was contacted and declined to cover the repairs under warranty, despite the vehicle being within the mileage limit when the issue was first documented and presented for service.

I plugged my usb to usb-c charging cable into my iphone 20 seconds after starting the vehicle. I proceeded to exit my driveway when the infotainment screen went completely blank and the same thing to the driver's display 10 seconds later. I drove to the end of my street to a stop light where the car completely shut off and automatically restarted within a few seconds. I was traveling with my wife and [XXX] daughter. I have yet to reproduce the problem but have an appointment scheduled with the dealership later this week. Zero warnings or messages were present before, during or after the incident.

The infotainment system has locked up and has shut completely off while driving. When it shuts down (screen goes black) or glitches, the car actually loses power. Luckily it powered right back on but it was scary and could happen again and be much worse. The screen/ infotainment system has had this issue for awhile. We’ve even told Volvo of Tulsa about it when it was in for service but they said they couldn’t do anything about it because they couldn’t reproduce the issue. We have also had the brakes and rotors replaced twice at the dealership because they seem to be lemons or faulty. We are currently dealing with vibration once again (conveniently now the warranty is out).

Check engine light illuminated at 11,000 miles. Diagnostics showed a software update was needed but the software update did not fix the problem. Volvo corporate said the IEM module needed to be replaced. The IEM module controls the rear axle / propulsion and this is a serious safety issue because sudden loss of propulsion while driving at high speeds increases risk of having an accident. After replacing the IEM module, the mechanic cleared the DTC codes, test drove the car, and re-ran the DTC - and the code indicating a software update was still needed was present. Also the hybrid battery doesn’t keep its charge and depletes at an extremely fast rate.

*WITH THE BOWERS & WILKINS SOUND SYSTEM* TWICE WITHIN 1400 MILES, THERE WAS A LOUD "POP" SOUND FROM THE SPEAKERS FOLLOWED BY NO SOUND FROM ANY PORTION OF THE VEHICLE. THE POP SOUNDED LIKE A WINDOW OR THE SUNROOF SHATTERED. ALL SOUND WAS LOST: SENSUS FEEDBACK, TURN SIGNALS, PARKING SENSORS, PHONE, ETC. THE ONLY THING THAT WORKED WAS THE BASS. AFTER THE CAR WAS PARKED AND OFF, AND RE-STARTED, EVERYTHING WORKED AS NORMAL. ODDLY, THERE WAS THE FEELING OF STATIC ELECTRICITY JUST PRIOR TO EACH POP. THESE POPS WERE CAUGHT ON DASH CAM FOR PROOF. THERE WAS STATIC HEARD IN THE DASH CAM VIDEO TOO. THE DEALER PROVIDED A "FIX" WITH A SOFTWARE UPDATE DESCRIBED IN TECHNICAL JOURNAL. TJ 35554.20-2020 (IHU VOLUME RESTRCTION WITH ORANGE KEY). THIS SOFTWARE UPDATE HAD NOTHING TO DO WITH THE PROBLEM I HAD. THE ORANGE KEY WAS NO WHERE NEAR THE CAR DURING ANY OCCURRENCE. SINCE THE UPDATE, THERE HAVE BEEN SEVERAL IDENTICAL LOUD POPS, BUT THE AUDIO CONTINUED WORKING. THE SAME STATIC ELECTRICITY FEELING OCCURRED MILLISECONDS BEFORE THE POP. ALL INCIDENTS OCCURRED WHILE ON A FREEWAY OR MERGING ON A FREEWAY, WITH MY PHONE ON THE WIRELESS CHARGER AND THE AUDIO ON AT LEAST AROUND 50%. MULTIPLE REPORTS OF THE SAME ISSUE ON A REPUTABLE VOLVO FORUM.
