NHTSA Complaint #11428661 — 2017 VOLKSWAGEN GOLF

Issues with thermostat housing: the part fails, causing a slow coolant leak. Coolant light eventually comes on. I bought my car in fall 2016. Issue first occurred and was diagnosed and fixed by dealer under warranty in April 2020. It has now (August 2021) reoccurred and has been diagnosed again by the dealer as the same issue. This should be a lifetime part. I should not have had to replace this part twice within a little more than a year, on a car that is just about five years old. Safety issue: possibility of sudden failure/overheating that might leave the driver stranded by the side of the road. Numerous others have reported this issue occurring repeatedly; please see https://www.reddit.com/r/GolfGTI/comments/drna5m/mk775_thermostat_housing_issue_and_coolant_loss/ VW has also settled a class action on a similar issue on an older generation of cars (Coffeng, et al. v. Volkswagen Group of America, Inc.) A class action involving the current generation of cars is currently in progress (Zhao, et al., vs. Volkswagen Group of America, Inc., et al.).
