2019 Audi SQ5 Tail Lights, Brake Lights and rear blinker failure. All lights inoperable with errors and warnings appearing on the dashboard display. Failed while driving home from a weekend trip in the evening approximately 1 hour from home. Had a friend follow behind me to reduce risk of any issues with other drivers colliding with my vehicle. The dealership inspected the vehicle and found numerous faults stored in comfort module for short circuits to B+ in lighting for rear of vehicle. Dealer performed software update to comfort module per technical service bulletin 2055123/4. As the owner of an expensive vehicle with Platinum extended warranty coverage, the dealership and warranty company (VWFS Protection Services, Inc.) claim software is not covered by my warranty. The dealership stated: "At this time the module has not failed, so there is no replacement needed. Audi has a technical service bulletin for optimized software to address this concern. That is where things would need to start with having the most current version. If there was a continued issue after that update, then it's possible there's a replacement of parts that would be needed." This is a serious safety concern. The vehicle software caused the failure. Audi has created a problem that caused the lights to become non-operational. This presents a clear and apparent risk to driver safety. This could easily be deemed grounds for a recall for leaving the vehicle in a dangerous condition. The vehicle tail lights, brake lights and rear blinkers do not work without the software update. The same statement can be made for the control module. They now fail to operate with this vehicle. If Audi chooses to fix the vehicle via a software fix instead of replacing them with parts that do work mechanically and/or electrically with this vehicle, that was the choice Audi and their dealership made, thus eliminating my warranty coverage for the fix, forcing me to pay full cost for their software errors/update.

First, the tail lights malfunctioned randomly. Both tail lights were out due to some software error that eventually resolved after a week. Thankfully this was covered by Audi, and there is a redundant tail light system in place. The error just suddenly came up and all main tail lights and turning signals failed. This could have ended terribly as i was driving at night. An additional issue is the power steering also randomly failed. This is probably my biggest issue so far. The vehicle has 37k miles, and the power steering randomly went out while driving. This could have been catastrophic if i wasnt on a small road. In winter this could have easily caused a crash either to the terrain around me or another motorist. Issue has been diagnosed as electronic steering rack failure. For both these issues there were 0 symptoms just a sudden loss.

The trunk lid has opened on its own while I was driving on the highway in the night time, some small cargo (made of plastic) fell out of the trunk and was destroyed by the traffic behind me and in adjacent lane while creating some minor road hazard. Instantly pulled over on a soft shoulder, put the hazard lights on and got out to check out what happened. The trunk was wide open but hazards were not visible as they are attached to the trunk lid which was open and facing upwards, effectively making the hazard lights invisible to the traffic in the night time behind me. Small reflectors on the bumper are so tiny that in the night time are practically useless and invisible to the cars behind you if they are cruising at highway speeds. A few cars behind me had to brake hard and change lanes. There are essentially two safety problems: 1) the trunk opened while driving (no sound or dashboard warnings) and 2) design flaw of the tailgate lights which are attached to the trunk lid instead of at least partially being attached to rear part of quarter panel. Since it was too dangerous to stay on the highway in the night, I pulled in to a nearest parking lot to report to Audi roadside assistance. Imagine the situation when someone gets a flat in the night on the highway and needs to change the tire themselves, if the trunk is open while you get the spare and tools, they are in great danger. Discussed this with Audi corporate and they sent me to a dealership for diagnostics but dealership could not replicate it. Seems like neither of them have a solution. Please investigate. Thank you.
