2022 Audi e-tron Brake Pedal Complaint

What Owners Are Reporting

An owner of a 2022 Audi e-tron has filed a complaint with NHTSA, identified as NHTSA ID 11510001, detailing a critical braking issue. On three separate occasions, the "brake pedal went all the way to the floor without stopping the vehicle." The owner noted that "Pumping the brake pedal did not help" as the pedal continued to go to the floor each time. After several panic pumps, the "brakes worked as if nothing had happen" suddenly, without a gradual return of pedal force.

Crucially, no indications or warning lights appeared on the dashboard during or after any of these events. Each incident occurred after the vehicle had been parked for at least four hours, suggesting a potential cold-start or initial operation condition for the 2022 Audi e-tron brake pedal complaint.

Diagnosis and Repair Attempts

Following these incidents, the 2022 Audi e-tron was taken to an Audi Service center for evaluation. Despite the owner's detailed description, the service technicians were unable to duplicate the issue during their assessment. The vehicle remained at the service center for 11 days while the problem was investigated.

Ultimately, the Audi technical team recommended replacing the brake booster module. This repair was carried out by the Audi Service center in South Burlington, VT. The original brake booster module was retained by the service center.

Potential Component Involved

The component identified by the Audi technical team as a potential cause for the intermittent brake pedal issue was the brake booster module. The specific part number for the replacement module was 4KE-614-100-AG-BEF. This component is critical for providing power assistance to the braking system, helping the driver apply sufficient force to the brakes with less effort.

If You've Experienced This

If you own a 2022 Audi e-tron and have experienced similar issues where your brake pedal goes to the floor, it is important to take action. Even if no warning lights appear, an intermittent braking problem can pose a significant safety risk. Document the circumstances of the event, including mileage, date, and any specific conditions (e.g., after parking for an extended period).

Contact your authorized Audi service center immediately to have your vehicle inspected. Additionally, you should file a complaint with the National Highway Traffic Safety Administration (NHTSA) to contribute to their database of potential safety defects. Your report helps NHTSA identify patterns and initiate investigations, such as the one related to NHTSA ID 11510001.

Important Warnings

Owners should be aware that intermittent issues, especially with critical safety systems like brakes, can be challenging for technicians to diagnose if they cannot be consistently reproduced. If you experience the "brake pedal went all the way to the floor without stopping the vehicle" symptom, ensure you clearly communicate all details to your service advisor, including the conditions under which the problem occurred.
