2023 Volkswagen Jetta engine problems

Car was started on afternoon of XXX and the Low Coolant alert sound and dashboard light came on. Opened hood and car was completely out of coolant. Took to Royal Automotive, Vestavia Hills, AL on Wednesday XXX to be fixed. Dealer assessment was “PERFORMED COOLING SYSTEM LEAK TEST. THE VEHICLE PASSED TEST. CHECK FOR VISUAL LEAKS. FOUND NO LEAKS, BUT FOUND SEEPAGE AT THE HEAD GASKET. VOLKSWAGEN SAID THIS WAS NORMAL PER 00-26-01 - DIFFERENCE BETWEEN FLUID LEAKAGE AND SEEPAGE. TOP OFF COOLING 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 XXX 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 [XXX] 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

About 6 months after I bought my car the check engine light came on, took to vw still under Warranty. And they said it was just a harness on sale about 4 months later, it came back on and they kept my car for a week. And when I got my car back about 2 to 3 weeks later, it came back on again, and they cound't figure it out and said its something wrong with the emmission and now it's back on so I don't know what's wrong with it, I took it to a different shop and they said they couldn't read the codes and I have to take it to Volkswagen dealership. Car is new and fail emmission.

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 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.

This is now the second time this has happened on my brand new 2023 Jetta SE. The vehicle only has 1831 miles on it. The fault happens when the car is being driven after approx. 15 minutes. EPC light, Check Engine Light, and Yellow Warning Light illuminate. Also sounds like a misfire when limping off the road. Codes read at dealer are P0304, P0363, P1D74, and P1D75. All of these codes relate to Cylinder 4 misfire. Car is driven only at highway speeds, since it is a commuter car. This happened on 2/16/2024 and 2/22/2024. I attached PDFs of the Service Invoice from the first instance. I also attached a PDF of a the federal safety agency file containing a list of VW vehicles that are having the same issue, with the same engine.
