The adaptive cruise control (ACC), forward collision warning, and automatic emergency braking/front assist systems have repeatedly malfunctioned. The vehicle has been returned to the dealership multiple times for diagnosis and repair, but the issues remain unresolved. These are safety systems designed to help prevent or mitigate collisions. When the adaptive cruise control and automatic emergency braking systems become unavailable or fail to function properly, I cannot rely on features intended to assist in maintaining safety. The loss of these systems creates a potential safety risk for me, my passengers, and other motorists. The vehicle has been presented to an authorized Volkswagen dealer on multiple occasions for these concerns. The dealer has attempted repairs, but the problems continue to occur. Warning messages indicating that adaptive cruise control, front assist, or automatic emergency braking systems were unavailable appeared before and during the malfunction. I thought before they were just faulty sensors. The dealer never explained these features were not functioning. The symptoms first appeared while the vehicle was under warranty and have continued despite multiple repair attempts. The car was purchased brand new from the dealer.

While you driving an annoying beep comes on with the message ‘Lane assist is not available’ The beep comes on then off for several times during the ride..it’s very disturbing and annoying for me and for my passengers..My vehicle which has 30000 miles is being used for Hire I consider this issue as a safety one and that the manufacturer has to take some action to solve the problem Thank you for your cooperation and looking forward to hearing from you soon Best regards

The vehicle experiences sudden loss of motive power during acceleration. Between 30–60 mph, the transmission fails to upshift correctly, causing the engine RPMs to spike to 5000 while the vehicle fails to gain speed. This creates a severe safety hazard when merging into high-speed traffic. Additionally, the infotainment system frequently blackouts and reboots while driving, and there are intermittent malfunctions with the power windows and door locks. Authorized dealerships have been unable to resolve these persistent safety defects after multiple repair attempts.

Travel Assist keeps showing unavailable and giving constant warnings

On April 19, 2026 at approximately 9:40 PM, I was driving my leased 2024 Volkswagen Tiguan southbound on [XXX] [XXX] . I had three minor passengers with me — my daughters ages [XXX] and [XXX] , and their stepsister age [XXX] . We were returning home to [XXX] from a family trip to Walt Disney World. Without any warning — no dashboard lights, no sounds, no hesitation — the engine completely lost all power at highway speed. I pressed the gas pedal repeatedly with full force and there was absolutely no response. The car decelerated uncontrollably in active nighttime highway traffic. We were stranded on the highway shoulder for approximately one hour before the car restarted. I drove home on side roads. This is a recurring defect. In December 2025, I brought the vehicle to Gunther Volkswagen of [XXX] , where it was documented on official repair order RO#XXX that the vehicle ‘SHUTS OFF AT LOW SPEEDS.’ The dealer replaced the EVAP canister and N80 purge valve under warranty. The defect was not resolved. In May 2026, an independent professional diagnostic by 4 Rings European using an Autel MaxiSys Ultra scanner (Report ID: XXX) found 30 stored fault codes across 19 vehicle systems, including fault code P253200 (Ignition Switch Run Position Circuit High) — directly consistent with the sudden engine cutout — plus active cylinder misfires on cylinders 2 and 3, three active EVAP system fault codes confirming the December 2025 repair failed, and a compromised airbag system (U140000 — function restriction due to low voltage). The vehicle was subsequently taken to Gunther Volkswagen of Coconut Creek again in May 2026, where the dealer diagnosed low voltage faults and replaced the battery under warranty. This is the second warranty repair attempt for recurring defects on this vehicle. I have filed a formal evidence preservation demand with Volkswagen Group of America’s General Counsel. I have also filed a BBB AUTO LINE arbitration INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
