2023 Volkswagen Jetta Engine Problems

“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.”

“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. …”

“On April 1, 2023 I leased a 2023 VW Jetta for 39 months. I test drove the car. Upon delivery, it had 12 miles on the car. I drove the car for 150 miles (162 TOTAL miles on car) At 11:30PM on April 6th, it left me stranded in the middle of the road. I called VW 36 month/36,000 roadside assistance for help. They asked if I was in a safe place. I told them No, I am in the middle of the road, in the middle of the night. They proceeded to tell me to call 911 and hung up on me. I then went to push the SOS button in my car, to my disbelief, “this feature is not active in your vehicle.” I called AAA. …”

“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.”

“Accelerator petal does not always result in acceleration from a stopped position. This causes the hill assist to hold and does not allow movement forward, resulting in an engine stall. The vehicle has also set the EPC light while traveling resulting in reduced engine power to the point of not enough power to move forward. Turn the ignition off, then on resets the EPC and limb mode.”
