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.
