replacement modules 1K0-907-375-AP or 1K0-907-375-AN. Furthermore, Page 2 text contains the technician's actual notes stating he only did a temporary module reset to force a signal and explicitly writes: "CONTINUED WITH RECALL AND FOUND MODULE REQUIRES REPLACEMENT." Due to this uncompleted safety recall repair and use of non-compliant hardware, the ABS module suffered a complete network communication crash immediately upon leaving the dealership lot. This sudden network failure cut off critical speed sensor data to the vehicle's transmission, instantly dropping the vehicle into an automatic transmission 'Limp Mode' while driving on public roads. The transmission locked into a single safety gear and refused to shift, causing a severe, sudden loss of vehicle acceleration and creating an immediate traffic hazard. When contacted immediately at 5:30 PM, the dealership refused to tow the vehicle to correct their failed recall remedy and demanded I pay an out-of-pocket diagnostic fee. The vehicle is currently un-repaired, hazardous to operate, and stranded.

Volkswagen told me on 7/25/2026 that the ECM needs to be replaced as they did not think it was safe for them to release the vehicle until this repair has been made and they were waiting for Volkswagen to authorize the repair. The representative later stated that Volkswagen will not authorize the replacement of the ECM and this is a safety concern. The dealership has not completed a repair for this issue and this vehicle does not need to be on the road for the safety of me and others. The dealership have told me I can pick up the vehicle and just bring it back if the safety issues occurs again, I refuse to pick up this car due to the safety issues and concerns. I have contacted the corporate office of Volkswagen and they have not responded to me on why they declined the authorization for this repair.

on me completely while driving. The first time it happened, they inspected the car again and assured me after several tests there were no issues with the car. I had the car back for about 2 weeks and then this past Friday 7/17, the car shut off on me again and I towed it to the same service center. They keep claiming it has nothing to do with the recall and provide me with service reports that say "no codes found" after their inspection. They want to charge me for additional tests and "mechanical diagnostics" as per the owner of the center. There is ample evidence online that suggests the symptoms I am experiencing with my car are exactly attributed to the recall they claim to have fixed. There was never an issue prior to getting the recall taken care of and the inspection at this service center. They do not care about my safety concerns and I am legitimately afraid to drive the car around. The only reason why I am not injured yet is because it thankfully has died while driving at lower speeds leaving work in a parking lot.

SYSTEM." The car was purchased new by me in October 2022 and my warranty expires in October 2022. It has just over 17,100 miles on it. Further, Volkswagen published a Technical Service Bulletin 15-23-01 - Head Gasket Leakage on [redacted] documenting known problems with head gaskets for my car's engine. Despite dealership stating the head gaskets is leaking, Volkswagen stated to the dealership it doesn't warrant repair. I believe Volkswagen should repair at their expense the defect of their vehicle. The dealership acknowledged the head gasket is clearly "seeping" coolant. Coolant shouldn't be leaking at all from a closed loop system. This is causing a potential safety issue for my [[redacted]] daughter who drives the car, as when the head gasket fully fails as documented by Volkswagen, the car could be in traffic and put my daughter's life and other peoples lives in jeopardy from a blown engine or an overheated engine. It's unacceptable that Volkswagen's direction is for us to carry around a gallon of coolant and constantly check the coolant levels because they don't want to fix their known defect. I called Volkswagen customer care and complained. They refused to assist, stating they stand by the dealership's assessment. I reminded them that the dealership was doing what Volkswagen directed, but that didn't change their decision. I asked for escalation, was told it was escalated twice and that their decision is not changing. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

This defect creates a serious safety risk because the vehicle can lose power and stall while in motion. The unexpected shutdown places the driver, passengers, and surrounding motorists at risk of a crash, especially when driving at higher speeds or in traffic. The problem has occurred multiple times and has persisted despite repair attempts. More than $1,000 has been spent on repairs related to this issue, but the problem has not been resolved. The vehicle has been inspected and repaired by service technicians; however, the underlying cause has not been successfully corrected. The vehicle has not been involved in a crash as a result of the defect, but the recurring stalling and loss of power present an ongoing safety concern. Volkswagen has been contacted regarding the issue, but assistance has not resolved the problem. Prior to the vehicle shutting off, warning messages including "Starter System Faulty" appeared on the dashboard. The issue is more likely to occur during hot weather conditions. These warning messages began appearing before the stalling events and continue to occur despite repair efforts.
