2019 Audi Q7

During summer 2026 the check-engine light on our 2019 Audi Q7 came on BEFORE its first August service/oil-change visit. The light remained on when the dealer returned the vehicle. Within days, the driver found cruise control no longer worked; it had worked before that visit. She called the dealer in mid-August to arrange a return. At the second visit, the dealer reported intake-manifold runner controls for banks 1 and 2 stuck closed and recorded: "water pump has failed internally, causing a vacuum leak". The water pump was replaced. After the second visit, around August 28, 2026, a high-pitched whining/squealing noise began. It occurred while coasting or going downhill and generally when the accelerator was not pressed, not only while braking. The driver initially suspected a brake noise. She recalls the dealer advising measures to remove excess brake material and saying it should not pose a safety risk. The noise persisted after those measures. At a third visit the dealer diagnosed a PCV/crankcase-breather issue. That repair remains outstanding. The earlier reassurance concerned a suspected brake noise before the PCV diagnosis. We request investigation of the persistent warning, cruise-control malfunction, diagnosed vacuum/intake-manifold issues and later PCV/noise complaint, including any safety implications for vehicle operation. Whether these faults are related is UNKNOWN; their timing alone does not establish that service caused them. Our specific concern is abnormal crankcase pressure from the PCV fault, including possible overpressure, oil leakage or seal damage and impaired engine operation in traffic. Actual pressure/vacuum measurements and any resulting damage are UNKNOWN; these are concerns for investigation, not confirmed events. Receipts are available. Actual fault codes, diagnostic tests, and repair records should be reviewed. Availability of removed parts for inspection is UNKNOWN.

My car has experienced unintended automatic emergency braking while driving in active traffic with no obstruction present. This created a serious risk of a rear-end collision from vehicles behind. Prior to this, the car had ongoing alignment and steering issues beginning shortly after purchase. The car consistently pulls while driving and has required multiple repair attempts, including alignments and inspections of steering and suspension components. These repairs have not resolved the issue. The problem appears to be worsening. In addition to the unintended braking, the vehicle intermittently displays safety system warnings related to driver assistance features. The failure involves both mechanical and electronic systems, including steering alignment and automatic emergency braking. It's believed that incorrect alignment or suspension issues may be affecting sensor calibration and causing false collision detection. The car has been inspected multiple times by the dealership, but the issue has not been diagnosed or permanently repaired. The car's unsafe to operate due to unpredictable braking behavior. The warning signs that the car gives are “Traffic jam assist unavailable” and “Safety system malfunction” while driving.These warning messages and system malfunctions have been occurring intermittently since shortly after purchase in early 2025 and were previously reported to the dealership. The warnings continued after the incident and are documented with photos taken the following day. The safety systems appear to be unreliable and malfunctioning in real-time operation.

The starter in my Audi Q7 2019 failed and the car would not start. I was parked in my garage and manually had to put the car in neutral using the tool provided in the trunk and push the car out of the garage until a flatbed tow truck was able to take my car to the shop. If this happened elsewhere, I could have been stranded without the ability to start my car. My car was towed to a certified shop where they confirmed the failure and made the repair by installing a new starter.

While driving, the vehicle’s infotainment system suddenly froze and then rebooted on its own. During the reboot, the display was unavailable for several minutes, causing loss of access to navigation, vehicle status information, and warning messages while the vehicle was in motion. This occurred without warning and distracted the driver while driving, creating a potential safety risk.

Drive System malfunction code appeared while driving. Engine then shut off immediately. Had it towed to Audi dealership. Fuel Pump and Fuel Pump Module Codes reported in diagnostics check: codes P3044, P1158, and P0148. There is a NHTSA campaign number 22V516 (Audi recall number 20DR) that has been reported on this same issue with the fuel pump, however, my model 2019 is one year shy of the 2020 Q7 to 2021 affected vehicle range. Asking NHTSA to look into other repeated fuel pump issues for the same model vehicle, but for 2019 models. I have read of other 2019 model fuel pump complaints that match the 2020-2021 recall. The 2019 models need to be included in the investigation and recall.
