   Sudden power loss or engine cut-out while driving

   • 9 complaints (17%)
   • median 3,421 mi at 1.1 yrs old (4 state mileage, few)
   • filed 2020–2026

   Owners describe sudden loss of power, bogging, or the engine cutting out while driving, including on highways, when merging, and when pulling away from a light. Some say an EPC or check engine warning light came on, and some complaints describe needing to clear fault codes before the engine would restart. Some complaints say the dealer found no fault during testing. Where mileage is given, reports range from under 1,000 miles to about 47,000, and most are under 10,000 miles.

   What to check: Ask for any stored fault-code records, including intake-air leak codes, and test drive with a full acceleration from a stop and a highway merge.

   “As I was driving home late last night from work on a city street , my car suddenly would not accelerate in speed while in motion but you can hear the car accelerate when I was pushing on the gas. It felt as if the car has turned off because then my steering wheel got hard was hard to move while in motion. Cause of problems is unknown but may not be safe to drive if it continues”

   NHTSA complaint #11388795, filed 2021-01, 843 miles

   “The epc light comes on randomly at highway speeds when revving up the engine to overtake cars. The engine suddenly bogs down and engine rpms are limited to 3000 when light is on. It could be a potentially dangerous situation because the car will not want to accelerate and forces me to get off the freeway. The only way for the light to come off is to turn off the car and turn it back on. I visited a local vw dealer and they informed me of a fault code p227900 intake air system leak passive/sporadic. …”

   Electrical system

   Electrical systems shut down or prevent restart

   • 8 complaints (15%)
   • median 25,000 mi at 2.7 yrs old (3 state mileage, few)
   • filed 2021–2026

   Owners describe the instrument panel going blank, the car shutting down while driving or at idle, or the vehicle failing to restart. Some complaints link episodes to heat, such as a car left in the sun or a hot dashboard that turned off the front panel, air, and stereo. Other complaints describe a no-start after a pothole hit, where a code showed the engine and powertrain control modules were not communicating, and a no-start where the dealer found an overheated ground wire. A report with mileage lists about 25,000 miles, and others describe heat, sun exposure, or a pothole hit rather than mileage.

   Recall 23V604000

   What to check: Ask whether the ignition switch recall 23V604000 has been checked against this VIN, and ask the dealer to inspect the ground wiring and harness connections for heat damage.

   “When I start the car Multiple times the car will throw over half of all the error code and could not start the vehicle. Driving in the highway doing 65mph with the cruise control on the car completely shut off and I had to limp it to the shoulder and was unable to start the car. Each time I cleared the fault codes then was able to start the car. If I didn’t have my scanner I would have had to get towed each time to the dealer. …”

   Owners describe sunroof glass breaking suddenly while driving or after a door is closed, with a loud bang and no impact or object seen. Some describe glass scattering across the sunshade or into the seat belt area, and some describe being cut by falling glass. A complaint says the dealer denied warranty coverage for the repair. Where mileage is given, reports fall between about 42,000 and 72,000 miles, and most describe the glass breaking while the car was moving.

   What to check: Look over the sunroof glass for existing chips or cracks, and ask whether any prior sunroof inspections or repairs are on record.

   “Vehicle's sunroof spontaneously shattered while driving, raining down thousands of shards of glass. There was a loud bang, it sounded like a firecracker went off. I was not behind another vehicle and was going 55-60 mph. Another issue that this brought up was that after I had pulled off and assessed what happened, I wasn't initially able to buckle my seat belt due to glass in the receptacle.”

   NHTSA complaint #11586466, filed 2024-05

   “While driving southbound on I-15 near Exit 300 (5300 S, Murray, Utah), the sunroof on my 2020 Volkswagen Jetta SEL suddenly and spontaneously exploded outward without any impact or external object striking the glass. The vehicle had approximately 72,000 miles at the time. There was no tint, film, or modification to the sunroof. The weather was clear, and the road was smooth. The explosion produced a loud gunshot-like sound, followed by glass fragments scattering across the sunshade. …”

   Electrical system

   Emergency SOS and connectivity module failures

   • 6 complaints (11%)
   • median 140 mi at 1.0 yrs old (1 states mileage, few)
   • filed 2020–2026

   Owners describe an Emergency SOS or Car-Net error light, a message that emergency services are unavailable, or a module that failed soon after purchase. Some complaints say a software update was followed by the SOS function being disabled and a fault light staying on, and the owner says the manufacturer declined a no-cost repair. The dealer found no problem at some visits, and after the warranty ended the dealer said a telematics control unit needed replacing. Some reports describe the warning appearing within days of purchase, and others say it has been intermittent since the vehicle was new.

   1 related service bulletin

   What to check: Check whether the Emergency SOS and Car-Net functions work and whether any fault light is shown, and ask whether service bulletin 11026186 on activating the emergency call module has been applied.

   “Vehicle has been displaying Emergency services unavailable along with lights for steering and braking systems, Intermittently since new. The dealer stated no problem found.. Now that the vehicle is out of warranty they tell me it needs a new computer module. I believe they said Telematics control unit.”

   NHTSA complaint #11632961, filed 2024-12

   “Vehicle is brand new and has been in my possession for 7 days. Car-net module and bluetooth audio modules have both failed. Car-net failed on day 5, bluetooth on day 6. Prescribed resolution involves pulling the appropriate fuse to reset the system. After this procedure, system failed to reset.”

   Electronic parking brake faults and unexpected engagement

   • 5 complaints (9%)
   • median 9,475 mi at 1.2 yrs old (4 state mileage, few)
   • 1 mention a crash, fire or injury
   • filed 2020–2026

   Owners describe the electronic parking brake engaging on its own while driving at highway speed, or engaging when shifting into reverse. A complaint says the car rolled into a wall while the owner was inside a building, and that no alert showed the parking brake was set. Other complaints show parking brake fault or engagement messages on the instrument panel, sometimes with a car that would not restart. Where mileage is given, reports range from about 2,200 to 66,000 miles.

   What to check: Test that the parking brake sets and releases as expected, and ask whether the dealer has checked for stored electronic parking brake faults.

   2 excerpts from owner complaints in NHTSA records

   “My car rolled into a wall on the other side of a parking lot while I was inside the opposite building. There is no alert/indicator/notification that the e-brake is engaged. There are alerts for the seat belt, air bag, truck/door opened, low gas, lights, etc. There is even a notification on the screen to remind me to grab my phone after I turn off the car and open the door. …”

Buying note. Buyers considering this model year may want to check for stored electronic parking brake and fault codes, and ask whether the ignition switch recall and the emergency call module bulletin have been addressed. A test drive that includes hot conditions and a check of the Emergency SOS function can help clarify these concerns for a specific vehicle.
