On XXX, I was driving northbound on US-101 from [XXX] to [XXX] to pick up a family member for an appointment. The vehicle had been operating normally at freeway speed. As traffic slowed for a construction zone near Summerland, I intentionally reduced speed to approximately 20 mph. At that point, I heard a sudden abnormal rotational mechanical noise from the engine compartment, best described as a flapping or rubbing sound. The noise had not been present earlier during the drive. Within moments, the engine lost power and shut down. The vehicle lost propulsion while in traffic, and power steering assist was lost after the engine stopped. I was able to safely maneuver the vehicle off the roadway. The engine would not restart. Before this incident, I did not observe any meaningful warning of an impending catastrophic engine failure. I did not observe an engine overheating warning, an oil-pressure warning, or any other dashboard warning indicating an imminent engine seizure. Before purchasing the vehicle, and during my ownership, I used Ross-Tech VCDS (Audi/VW-specific diagnostic software) as part of proactive maintenance and monitoring. Nothing identified an impending catastrophic engine failure. The vehicle was transported to an independent European repair facility for inspection. The shop determined that the engine is mechanically seized and advised that the precise initiating cause cannot be determined without engine disassembly. An Audi dealership likewise indicated that additional manufacturer-level diagnostic procedures would be required. A case was created, and Audi declined assistance. I am submitting this complaint because the engine failed suddenly during normal operation without a meaningful advance warning, resulting in an immediate loss of propulsion in traffic. I believe this type of unexpected catastrophic engine failure presents a potential safety concern if it occurs while the vehicle is being operated on a public roadway.

What owners say
On or December 5th, 2025 (4 days after taking possession of the vehicle, I experienced a sudden and severe steering system failure while driving. When turning the steering wheel (even slightly), the vehicle produced a loud buzzing/grinding noise and the steering effort increased significantly, creating an immediate safety hazard. Because the steering issue worsened quickly and made the vehicle difficult to control, I stopped driving and brought the vehicle to an authorized Audi dealership for inspection. The Audi dealership confirmed the steering failure was caused by a major power steering system defect, including active power steering fluid leakage from the steering rack area consistent with internal seal failure, and the power steering pump being faulty due to fluid loss. The dealership advised replacement of the power steering rack and pump and stated the vehicle was unsafe to test drive due to its condition. During the same inspection, the Audi dealership also identified additional serious safety-related defects, including a brake system condition where the brake pedal slowly sinks toward the floor when pressure is applied (indicating a braking system performance failure requiring brake fluid exchange and further diagnosis if unresolved). The inspection also documented multiple additional mechanical and safety concerns requiring extensive repairs, including suspension and drivetrain defects and other conditions indicating the vehicle was not roadworthy as sold. The vehicle remains available for inspection. This incident involved a sudden loss of steering assist and braking abnormalities that could lead to loss of control, crash risk, and injury to the driver, passengers, and other motorists.
Complete loss of steering control while driving at low speeds. Dashboard indicator illuminated for "Severe Steering Malfunction - Do Not Drive." Had the car towed to the dealership. Dealership indicated that the car needed a new steering rack and pinion. Cost estimate was $4000. The car had 72,000 miles with mostly highway mileage.
Was driving on small town road, pulling into gas station, and 'steering malfunction, stop car immediately' notice popped up, with red steering wheel icon above message with line across wheel and exclamation mark. I lost power steering at the same time, immediately. Very difficult to drive, and thankful it was not on busy, interstate road, and that nothing more happened. Very tough to drive, and so far, need to tow to Audi dealership to check and repair. I have been in touch with Audi, nothing they can do over phone, they suspect electronic issue. Very dangerous and disappointing. Just happy it did not cause death or injury.
Driving down the road at 50 mph and warning light came on stating "Steering Malfunction" and lost all steering capacity and had difficultly safely exiting the traveled road to safe location. No steering and avoiding a rear collision due to unexpected breaking to handle car.
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.
Power steering assistance unit stoped working suddenly while driving. Then car was very difficult to steer. Fault could not be reseted, unit was not accessible with service computer in Audi shop. The steering unit was replaced. Just by luck that did not happen while driving at high speed. This could have been resulting in crash with casualties. While browsing the internet for advice it shows multiple incidents with the Audi electric powered steering unit. In the attached pic’s it shows a wet rubber seal and a corroded drive shaft of the replaced part (note the part numbers). Water and oil can find its way into the resolver unit and render it useless, cause lost of feedback signal hence kill the unit. Additional observation: Month before this incident happen, while driving at low speed in warmer/hot environment, a stepper motor feeling was noticeable on the steering wheel. Also a sound can be heared similar to rubber scratches over a dry surface. The disturbance went away when the car cooled down for some hours. It would be advisable to investigate the issue further as the consequences of loss if steering power could be very serious. Wishing everyone a safe travel.

Driving about 25 mph power of steering wheel was lost, steering became very hard. I stopped, no accident. Not reported yet. Messages appeared: 1. Steering: malfunction! please stop vehicle 2. Audi pre sense 3. Lane departure warning 4. Emergency assist
Steering wheel intermittently gets really HARD to turn. Like a total loss of power steering assist. This only usually lasts a moment or two, then functions as normal. Always while driving, but not always while navigating a turn. Might only happen once or twice a week... Really frightening. Dealer has performed numerous repairs, including even a new Rack (at my expense) It doesn't happen again for a while, and then it does the same thing again.
