2022 Volkswagen Jetta Electrical System Problems

OBD-II port is not connected properly meaning that when a checked engine light came on I am unable to diagnose the issue.

Rear brakes replaced twice on warranty. The car only has 24,000. Car remains with loud chattering brakes on all 4 brakes especially when brakes are cold. Especially loud chattering and squealing brakes still exist especially on rear brakes. Issue with a fuel valve needing to be replaced on warranty. EPS engine light on dash. Driver's door widow regulator malfunction for door not going down with one touch. Replaced under warranty. Dealer for VW stated that they would no longer do any brake repairs. Obviously, the material being used for brake materials is cheap and doesn't last. Have had situation with the main radio Information screen going blank on 2 occasions and having to do a hard reboot to get it to work. Cause unknown for screen totally going blank.

It has been about over 3 weeks that my travel assist alarm has been going off without any notice.

This vehicle has a "digital cockpit" without traditional analog gauges. It completely shut down on me while driving on the freeway, leaving me without a speedometer, and a red caution "do not drive" warning indicator. I have a video of this incident captured by my partner that I can share, as well as a static image, which I attach therein. Prior to this incident, it repeatedly shut down while driving, but in those cases would come back up in 5 to 10 seconds. This may have been a computer "crash" as it came back up with 0 on the trip odometers. The dealer seemingly fixed this problem with a reset process described in a TSB. In the most recent incident, the display never came back online, and I was unable to safely continue driving. There are also random issues with this display locking into "night" mode during the day, usually after backing out of a dark garage or going through a tunnel, which leaves the display impossible to read in bright sun. The only fix when this happens is to pull over, turn the car off, wait 5 minutes, and resume driving.

Engine misfire on all cylinders. Engine start/stop failure, check engine light illuminates. Vehicle hesitates and looses power when accelerating. Vehicle then stalls while operating. Happens while in traffic or trying to pull out from intersection causing vehicle to stop in roadway. Almost causes crashes from rear due to sudden stop and sides due to not clearing the intersection. Dealer confirmed the issue but states there is no repair or known fix. Dealer said to use premium fuel which is not required by manufacturer. Problem still occurred with premium fuel. Several trips to two separate dealers and both state there is no fix for the dangerous issue just to keep driving it. The vehicle is available for inspection. This issues is occurring in other 2022 jettas and Taos models. Dealer stated they were aware of the issue but vw does not have a fix. Has occurred multiple times with my vehicle.

Vehicle problems experienced on 7/22/23. Traveling on Route 93 north to exit 17 just north of Concord, NH at 8:00pm. Used cruse control for most of trip, set to 60mph and 65 mph. The distance feature was working, what a PITA it is. Some where around Concord, NH a warning message in orange was displayed, “Engine speed max 4000” in center of display, an orange triangle with an “!” marked appeared just below the temperature gauge on left side of display, a yellow car with “!” on side appeared just below the estimated mileage remaining – it switched between that car and “EPC” cruse control was no longer available Stopped, checked the engine for over heating however it did not seem tooo hot, fans were not running (engine was off) Started again, lights were OFF. Rest of trip was on local roads so never tried cruse control. Left to return home around 2:00pm all warning lights OFF. Some where around Manchester, NH same thing happened plus orange picture of engine on right was illuminated, Cruse control would not maintain speed and then said unavailable. On hills vehicle would not move along with traffic even when foot was put to the floor. Drove directly to Colonial VW, did not shut vehicle OFF however nobody was available to read the computer codes. Scheduled appointment for Friday Driving home it was almost impossible to merge onto Route 93 even with accelerator pushed to floor. What ever the problem with your programming is the major fact that the vehicle is not able to keep up or merge with traffic even on local streets it a Major Hazard. VW may be concerned with saving their engine – I’m Concerned for my LIFE

The contact owns a 2022 Volkswagen Jetta. The contact stated while driving 50 MPH, a knocking sound was coming from the engine compartment, and the vehicle started shaking and stalled. The contact stated that the check engine and electronic power control (EPC) warning lights were illuminated. The contact pulled the vehicle over to the shoulder of the highway where the vehicle remained. Neither the dealer nor the manufacturer was notified of the failure. The vehicle was not repaired or diagnosed. The failure mileage was approximately 4,500.

Electronic Power Control (EPC) issue: The car unit bogs down the acceleration and limits the RPMs, making it dangerous to drive on high way or even local road. The issue pops up spontaneously but went away after car was OFF for hour and restarted. Engine runs ruff and shacks along with laud banging sounds from under car. Suspect sensors, other messages seem to be out of place, such as "turn lights on" in morning when driving directly into sun light or the large red accident display with nothing around at all, different locations. Scan taken of car by dealer, nothing to explain why, however 2 plugs were somewhat dirty & will be replaced, only 1800 miles on car. Other errors on display, the yellow Front Assist which switched between that and the ECP, to far left under the temperature a yellow triangle priority symbol (some what red) These all came on at time of fault. Speed varied from 20 to 30 even when pushing pedal to bottom.
