SUSPENSION
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.

SUSPENSION
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. It’s is very common in Audi Q7 models from the year 2017 - 2023 where the PCV valve have a defect and the marker on the front passenger and driver side lights as well are out. These are both very costly repairs that are thousands of dollars that truly hurt the consumer. They know that the 3.0 L engine had a severe problem with the PCV valve and crack case and they have not warned customers and it’s truly hurting the consumer in this economy. Please file this petition and I bet customers flock as I saw a Reddit thread with thousands of people complaining about the same common issue and problem with their Audi Q7.

ELECTRICAL SYSTEM
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.

ELECTRICAL SYSTEM, ENGINE, POWER TRAIN
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.

EXTERIOR LIGHTING
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.

ENGINE
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.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
Twice, without logically-relevant symptom or warning, when the vehicle attempted to accelerate from a low speed in the middle of a busy intersection, the AEB incorrectly activated, suddenly stopped the vehicle, startled the drivers, and nearly caused accidents. Turned out, this was known behavior caused by a design defect software bug in the "door control modules" for which a software update had been released but never publicly announced. Audi charged us $315 for the software update, but since it is a manufacturing defect causing a critical safety issue, it should be covered by a safety recall, all owners of Audi vehicles with the affected "door control modules" should be proactively notified of the software update and should receive it without cost.

ENGINE
For over 24+ months now, the engine has been showing signs of excessive oil consumption. I've had the engine light come on requesting for me to add a quart of oil...on average, every 2,000 miles. I'm concerned with this excessive oil consumption as it is a major safety issue, as the piston rings may fail due to a possible faulty engine design (most likely since this excessive oil consumption is a frequent occurrence with other drivers of this vehicle). When discussed with the dealership, they are aware of the situation (2017-2019 Audi Q7 excessive oil consumption) and they request that I pay for an engine compression test. This amount of oil consumption shouldn't happen.

First time on highway since getting it back from the car repair vendor two days prior. Drive system malfunction occurred on the highway drive approx.13 miles from my house. Car lost power and would stall and would barely idle. Stopped in the middle of highway traffic 3 times. Got the car towed to vendor that had serviced my car 2 days prior which involved changing rear brake pads and rotors, 6 supercharged spark plugs and air filter. Estimate of issue was damaged exhaust valves on cylinder 2 & 4. Recommended service was remove the cylinder heads, replace all exhaust valves, clean pistons and combustion chambers $8,032.99.
