2018 AUDI Q7 Complaints

Passenger side rear coil spring broken, shocks leaking. Confirmed by dealer. No warning lamps, messages. Potential safety risks include: Suspension compromise with the balance and alignment of the vehicle. There is a risk of loss of control especially with emergency maneuvers or sharp turns. This leads to poor vehicle control, increase risk of roll of vehicle and braking control. Can cause uneven wear on tires which can cause a blow out or loss of grip on roads. The leaking shocks puts stress on other parts of the vehicle. Suspension may not respond correctly if the vehicle were to hit a pothole or make a sudden turn. The broken coil can puncture a tire, causing loss of control which can result in an accident. The vehicle is garaged year round, maintained very well, with no excessive wear and tear. One owner vehicle.

The rear passenger side suspension spring coil broke while driving. The possibility of this failure puncturing a tire, dislodging from the vehicle into traffic, or causing control/stability issues of the vehicle is significant. The vehicle has been towed and is sitting until a fix is determined. No warnings were given before the incident. It happened on a smooth, flat, straight road at the time of occurrence.

This is a well known issue and multiple People have reported on this issue to Audi.

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 NHTSA. 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 NHTSA will take appropriate action to ensure the safety of all drivers affected by this defect.

We had a warning light go on on the dash advising there was an issue with the driver's side side marker lamp. In looking at the lamp, it is still illuminating, just not as bright as normal. This is a known issue with Audi - several complaints have been made already and there is even a recall on certain vins. My vin was not included in this so the cost is falling on me (in the form of $6200 not including tax) despite this being the exact same issue in the recall.

The engine burns oil. At about 60k miles started to burn about a liter every 10k miles. Once the engine got to about 80K engines it started burning a leter about every 1K miles. The high amount of oil consumption fouled the spark plugs, coils, injectors and sensors. This resulted in a drive system malfunction, caused loss of power in the engine that ultimately ruined the engine with less than 100K miles.

Engine Rebuild/Replace: Cylinder 1 intake valve has broken causing misfire/ oil consumption. Due to piece of valve falling into combustion chamber, damage/scoring on cylinder wall. Recommend replacement of engine
