NHTSA Complaint #11703443 — 2022 VOLKSWAGEN TAOS

2022 Volkswagen Taos SE 1.5T (DNKA engine, <60,000 miles, <5 years old) developed internal coolant leak from cylinder head gasket. On 11/03/2025 Smith Volkswagen, Wilmington, DE (RO 692953/1) performed coolant system pressure test and confirmed leak coming from cylinder head gasket area at rear of engine below turbo (exactly as shown in Figures 1 & 2 of VW TSB 15-23-01). Dealer noted possible related engine damage that may require complete engine replacement in addition to head gasket. Vehicle available for inspection upon request. Safety risk: loss of coolant can cause sudden engine overheating, power loss, or seizure while driving, creating risk of crash, stranding, or fire. Symptoms began November 2025 with “Check Coolant” warning; reservoir was below MIN. Added coolant once; warning has not returned, but pressure test proved ongoing internal leak. No visible external drips. This exact failure is a known manufacturing defect per Volkswagen Technical Service Bulletin 15-23-01 (Transaction 2071245/1, issued 08/17/2023), which states: “Original engine production head gasket design can lead to coolant leaks” and was redesigned as of engine DNKA 234 458 (July 27, 2023). Despite VW’s own bulletin documenting the defective gasket in all 2022–2023 Taos/Jetta 1.5T engines built before the fix, VW classifies the TSB as “information only” with no warranty coverage. VW Goodwill offered only 50% assistance on the $4,927 head gasket replacement and nothing toward a potential full engine replacement, leaving owner responsible for thousands of dollars in repairs on a documented factory defect in a low-mileage, young vehicle.
