Audi A6 collision warning problems

Filed Mar 28, 2024 · Driver assistance · CA

I am the original owner of my vehicle and have had my vehicle maintenance done at Niello Audi in Sacramento, CA. In May 2023, the forward facing camera on my 2016 Audi A6 stopped working. The dashboard error message was "ACC and Audi braking guard Unavailable". As a result, the automatic emergency braking, forward collision warning, lane keeping assist, and cruise control stopped working. In June of 2023 I took the vehicle in to the above named dealer and they indicated that the front facing camera would need to be replaced but they could not do so because the part in on back order. The part number is 4H0907217FX. Ever since June 2023, the dealer has indicated that the part is still on back order and unavailable. Today March 28, 2024, I contacted AUDI USA and was informed that Audi stopped making that part and it is no longer available. I have been waiting almost a year for Audi to correct this to no avail. The part in question is tied to several safety systems (emergency braking, collision warnings, etc.) and I feel that my vehicle is unsafe to drive. Obviously, this concerning safety issue affects all Audi owners in the United States and I think Audi should immediately be required to fix this safety issue.

The camera associated with the adaptive cruise control and collision warning systems thought there was an object in the road multiple times while on active cruise control. This resulted in the brakes being engaged - could have been rear ended very easily causing an accident. The camera system has now stopped working all together resulting in the safety systems being disabled entirely as well as the cruise control. After researching the issue and talking to the dealership I have found the camera to be a very common part failure with all Audi's. I can't even get the part there is such a large demand for repairs.

Received a message for "Electrical System Failure" and drove ok at first but began receiving failure messages for various systems including but not limited to Start/Stop system, transmission, power steering, and crash avoidance systems. Soon after the entertainment and comfort system screens went blank followed by the dash screen and the car eventually just turned off as I was trying to find a safe place to pull over. Safety was put a risk as I was stranded on a busy road with no shoulder and because the battery was impacted my hazard lights only lasted a short time which left me and my vehicle exposed on the side of the road. The car was towed to the dealer (Audi of Albany) who inspected determined the failure was related to a faulty ignition generator. The car is currently at Audi of Albany and will be for at least 2 weeks so I am assuming it would be available for inspection. Many different warning lights appeared in the short time leading to total shutdown of the car. I recall a start/stop failure message, batter charge low, transmission failure light, power steering failure warning, adaptive cruise control, frontal collision avoidance among others. As stated above all screens in the car eventually turned off and the car fully failed on a main road and required a tow to the dealer.

On my way to work, my car alerted me to an electrical malfunction and told me to call for service. When I called my Audi dealership, they told me to bring it in for service the following week. After asking if the car was safe to drive, they told me they wouldn't know unless they looked at the car. After pleading with them, they agreed to an appointment that day. On my way to the dealership - about 10 minutes into the trip on a highway, driving at highway speed, all electrical systems in the car started shutting down, and quickly - air conditioning, all safety features like lane keep assist, collision avoidance, etc. The steering became very heavy, the brakes were underperforming. After slowing down safely, the car shut down and was completely immobile and inoperable.

Starter warning followed by electrical system malfunction, these were followed by Multiple warning lights (Lane departure, adaptive cruise control, collision avoidance, etc) then 1 minute later transmission failure and engine failure imminent.... pull over immediately and contact dealer. I turned into a road off main highway within a minute of the last two warnings and as I turned, my center MMI went blank then my electronic dash went blank, transmission went into neutral and the engine died all within a few seconds. Fortunately I was able to coast to a stop.

Massive safety liability here. My 2019 Audi A6 was on the highway traveling at 75mph on 4/25/2023 at noon when with no prior warning, all of the electrical systems started failing rapidly. In the course of 90 seconds, there was an electrical malfunction warning, quickly followed by malfunction warnings for steering, brakes, and cascading shutdowns of all systems like the transmission, ABS, Collision Warning, Lane Departure, lights, hazard warning lights, instrument screens/clusters, HVAC, windows- literally everything. A complete failure of every component and safety system while driving highspeed is extremely dangerous. Had this happened at night, I would have been bricked in the middle of the road without headlights, hazard lights, airbags, etc. The car had to be towed away to the dealership and is available for inspection. The dealer is aware of this issue and called it a 48 volt starter/ alternator issue which is apparently systemic/ widespread with 2019-21 Audi 48 volt architectures; parts are generally backordered for months. Please take note: There is an extremely high risk that someone will be killed and seriously injured as a result of this defect. The vehicle is awaiting inspection and repair at an Audi dealership. It is under extended manufacturers warranty at 50,700 miles. No other diagnostics/ inspections/ or reports have taken place yet.

Multiple warnings indicating to contact dealer (Lane departure, adaptive cruise control, collision avoidance, electrical system, start/stop, etc) then 1 minute later transmission failure and engine failure imminent. After a minute or two my center MMI went blank then my electronic dash went blank, transmission went into neutral and the engine died all within a few seconds. Fortunately I was able to coast to a stop in the center median of an expressway and contacted the dealer. Flatbed towed to dealer who stated most likely the generator between the lithium battery bank and gas engine failed. They have seen several in this year for A6 and A7's with mild hybrid engines. I was lucky to be in low volume traffic as there was no power to indicate to drivers around me that my engine quit and not even turn signals worked. After having car towed to Audi dealer, they proceeded to tell me it was the starter/generator and the part was on back order for two to three months.

On sunday february 21, 2021 at about 330pm on rt 30 in amsterdam ny we were driving in stop and go traffic less than 30mph. As the car in front of me started to slow in traffic I started to brake my a6, at about 20mph and about 1.5 car lengths behind the car in front of me the audi presense collision warning screen activated with a red screen in the driver's cluster and a "chime" the car then went into emergency collision stopping mode...car's antilock brakes activated bringing my car to a complete stop in traffic. Traffic in front of me never stopped and I was at a distance that I had complete control of my car with more than enough distance to slow or stop my car safely. The car behind me came within inches of rear ending my car. I'm speculating that the driver behind me did not expect me to stop dead in traffic anymore than I did. Traffic conditions and distance did not warrant the presense to warn at all let alone activate the emergency collision response braking. This is the third malfunction of safety systems I have reported to the federal safety agency re: malfunctions of advanced safety systems. Audi USA is unresponsive.
