The contact owns a 2018 Audi Q7. The contact stated that there was an abnormal fuel odor inside the cabin of the vehicle at start-up, and the MMI System warning light remained illuminated. The vehicle was taken to a local dealer, where the vehicle was diagnosed, and the contact was informed that the fuel pump was faulty and needed to be replaced. The vehicle was repaired; however, the MMI System was not fixed. The manufacturer was notified of the failure. The approximate failure mileage was 93,000.

The Audi MMI system, which controls almost everything (radio, navigation, vehicle settings etc) shuts down and restarts every few minutes all by itself. The MMI system restarts completely randomly. It started out of nowhere a few months ago and happens whether driving or parked. Since then it is happening more and more frequently, making the system unusable at times (meaning navigation, radio, etc do not work). I'm afraid this issue is in the vehicle's computer and other components of hte car could be faulty, putting myself and other drivers with Audi cars at risk of injury or death if something with the computer fails. I have researched this issue extensively online and this seems to have appeared in numerous different Audi models and years. This also seems to have started happening fairly recently in most cases. I have not and will not take my vehicle to the dealership for diagnosis because I know they will charge a few hundred dollars just to tell me they cannot find anything (this is what many people have already posted online). There is an OBVIOUS computer system issue with Audi vehicles affecting their MMI system and some sort of fix is needed, for the safety of all vehicle owners.

To Whom It May Concern, I am writing to formally report a serious and recurring safety issue involving my 2018 Audi Q7. The vehicle has experienced repeated drive system malfunctions that result in sudden loss of power, reduced acceleration, and warning messages on the dashboard such as “Drive System: Malfunction” and “Electrical System Failure.” These incidents have occurred while the vehicle was in motion, creating a hazardous situation for both the occupants and surrounding drivers. In my case, the vehicle unexpectedly lost power while driving at highway speeds, forcing me to maneuver to the shoulder with diminished control. This sudden malfunction is unpredictable and could easily result in a collision or serious injury, especially in high-speed or high-traffic conditions. Upon researching this issue, I found that numerous other 2018 Audi Q7 owners have reported similar problems. These complaints consistently cite the same symptoms, including sudden deceleration, electrical system errors, and power steering failure. It appears to be a widespread defect that may warrant a recall or further investigation by the federal safety agency. I urge your office to investigate this matter promptly to prevent potential injuries or fatalities. I am willing to provide service records, diagnostic codes, photos, or any other documentation that may support this complaint. Thank you for your attention to this serious safety concern. I hope the federal safety agency will take appropriate action to ensure the safety of all drivers affected by this defect.

Getting error message again regarding "Front Right Side Marker Light Defective". This issue was already addressed back in late 2024 by my local Audi service center, but has popped back up again for the second time. My car has a little over 100K and has no other problems. There was an Audi recall Campaign 97CB (the federal safety agency campaign ID #16V642000) that addresses this exact issue and applies to some affected VIN numbers, but mine is not included. Seem to be occurring with a lot of regularity based on research online.

I researched this issue and noticed a widespread problem with the light detection of the 2017 modes and the 2018 Audi Q7 left front-side marker light. I have had this issue with my vehicle twice, resulting in over 4,000 dollars in repairs each time. I noticed that the 2018 models were left off, but I am sure there are more owners with this exact problem, and I believe this recall should be granted to 2017-2019 owners since the vehicles are in the same generation and have the same vehicle components on them. This is a widely known issue and a clear cash grab for Audi as the repair process to fix this is over $4,000 dollars each time, and the issue has not been resolved and is not covered under many warranties.

The problem: I was driving and noticed a high remaining fuel range, or a fuel gauge that appears to be stuck at a specific level, I ran out of gas while in motion, and my engine stalled almost causing a crash on the highway. My vehicle was towed to the Kansas City Audi dealer and they have identified the same issue in the recall in the federal safety agency campaign number: 22V155. Audi’s own number for this recall is 20DN. The dealer has quoted $5,000 to make the repair (My vehicle is currently at the dealer). My 2018 Q7 has the same engine as the 2018 A7 where there is a recall regarding the same reported issue. "The fuel level sender, which is located inside the vehicle’s gas tank, may get stuck on the gas tank’s ventilation pipe, leading the dashboard display to show an incorrect gas level and remaining range level."

My Audi with 42k miles ran out of gas on the Interstate Highway without any warning. Failure was a fuel sending unit which provides fuel quantity info and the low fuel light. The erroneous display indicated just less than half tank and the display indicated 185 miles to empty. This failure of the engine to suddenly quit on a busy freeway is potentially catastrophic! At a minimum there should be a safety recall requiring the Audi company to design the low fuel light to be on a separate circuit.

1.Interior color light bars: These light bars developed inconsistency. Audi repaired the inconsistency however now the light bars only display pink (not white) during start up. The dealership tried telling me it’s not pink, then claims to be color blind. I have artiest friends who maintain the color is pink. 2.Engine start-stop: Dealership confirms the Q7 will shut down as part of the start-stop feature before the vehicle has stopped. I explained to the dealership that the Q7 speedo claims moving 1 to 2 mph faster than it is moving. Therefore, during slow speed braking, stop sign, the Q7 will shut down before it stops moving. Without the engine on, the Q7 will lurch to a stop or and forcing the transmission to turn. 3. Low oil light comes on between oil changes sometimes.
