2023 Volkswagen Jetta Engine Problems

My 2023 vehicle has needed coolant topped off every 5-10K miles. This appears to be a very common occurrence for several owners however dealerships are just telling folks to top off as it's due to evaporation (it's a closed system and shouldn't evaporate). It is due to a faulty head gasket that VW even later redesigned. If you review reddit and numerous forums about the 1.5T produced before July 2023 it is a known issue that caused VW to redesign the headgasket. The powertrain warranty on new vehicle purchases is very short (50K miles) so they avoid replacing and tell folks to just "top off" until the warranty expires.

While driving home from work (I travel with the railroad weekly) on Thursday, [XXX], I had my vehicle set on cruise control going west on [XXX] in TN. Out of nowhere, my engine overheated and I lost my coolant. Upon pulling over, I observed no trail of coolant and nothing leaking under my vehicle. I refilled the coolant and made it home. The next morning, my coolant tank was empty again. I took it to my local VW dealership and was informed that the head gasket needed to be replaced. Upon research, I found that on August 17th, 2023, VW put out a Technical Service Bulletin stating that the "Original engine production head gasket design can lead to coolant leaks." This Bulletin did list the engine for my vehicle purchased that year. I was told that "Our manager name is Tim. He informed me that TSB is sent out when they are seeing these issues occur. It is a tech tip to help the technician diagnosis the vehicle. Your vehicle is out of warranty therefore it wouldn't be cover." The engine issue is well known with VW, with a statement that the issue is known. The Bulletin also advised "Improve head gasket design and coating as of Engine Number DNKA 234 458 July 27th 2023." So there is a fix to this issue and BW refuses to fix the issue at hand and is attempting to charge just under $3,500 for the repair.

The contact owns a 2023 Volkswagen Jetta. The contact stated while operating the vehicle, the check engine warning light remained illuminated.

The vehicle was not yet repaired. The manufacturer was notified of the failure, but no assistance was offered. The failure mileage was 43,000.

The check engine light would come on due to it misfiring on cold starts, dealer seems to have fixed it by replacing the coil packs. Many others also have this issue and haven’t been able to get it fixed. This is a serious issue that seems to be only happening on 2023 and newer model year Jetta GLIs.
