2021 Volvo XC90 T5 SUV FWD

With 2700 miles my XC90 has the Emission Control System light is on. The engine noise is considerably louder than normal (being a hybrid the SUV is pretty quiet) and it is not using the electric option.

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.

ELECTRIC PARKING BRAKE ENGAGING VIOLENTLY AT HIGHWAY SPEEDS AT LEAST. 3 TIMES. RESULTING IN ABRUPT STOP IN MOVEING TRAFFIC! DEALER IN NO HURRY TO REPAIR SUGGESTING BRING BACK WHEN THEY ARE ABLE! AM NOTIFYING VOLVO, DEALER , THEY WILL ASSUME ALL LIABILITY FOR INJURY OR DEATH FOR THIS DEFECT AND LACK OF CONCERN IN REPAIRING ( TOLD A SOFTWARE PROBLEM , BUT ALSO TOLD CAUSED DAMAGE TO OTHER COMPONENTS DUE TO VIOLENT AND ABRUPT STOPS! VERY UNCOMFORTABLE ESPECIALLY SINCE REPAIR MGR IS SO ARROGANT!

*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.
