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.

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.

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.

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.

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.
