2020 Volkswagen Jetta Complaints

FORWARD COLLISION AVOIDANCE — Filed 04/08/2026

Volkswagen mandatory software update/campaign 24Fi corrupted the OCU/Telematics firmware on my vehicle. This firmware corruption deactivated the critical emergency SOS safety system (Automatic Crash Notification), leaving a persistent red fault light on the overhead console. The dealership confirmed the internal malfunction code(B105207 & B200049) occurred immediately after they performed the flash, but the manufacturer is refusing to remedy the compromised safety system at no cost.

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. Fortunately, the sunshade was closed, which prevented most of the glass from falling into the cabin. However, the incident caused a significant distraction which posed a serious safety risk while driving at highway speeds. No warning lights, messages, or symptoms appeared before the failure. The glass appears to have shattered from internal stress rather than impact, as there were no visible signs of an object strike. The vehicle has not yet been inspected by Volkswagen, law enforcement, or insurance, but the glass remains available for inspection if needed.

October 9, 2025 EPC light on. October 10, 2025, called Brown's VW in Charlottetown, PEI and brought the car in. The EPC light was off. The scan revealed that turbo on the vehicle had a seized wastegate. The cost of repair is $4,026.85 and a wait for parts. If the EPC light was flashing, the vehicle would buck and stop in the middle of the road causing a safety issue. There were no warnings previous to the EPC light going on. the vehicle is out of warranty but low mileage. Please note I spend 6 months a year in PEI, Canada and 6 months in the US. My address in Canada is: 81 Kilkenny Rd., Rte 250, Harrington, PE CIE 3A5. The vehicle is registered in PEI and had a RIV certificate. I was also told by an independent source that the above problem is common in the Atlantic Provinces because of the position of the wastegate and also the salt in the air in the Atlantic Provinces. I am certain in sea coast areas of the US, there is a similar problem with this VW turbo and the VW Tiguan is also affected. Many years of the VW Jetta have the same problem.

While driving down a the road, my husband, 2 children and I, with no cars around us, we heard a loud pop (almost exploding like). We all looked around and then my husband looked up and our sunroof glass was shattered. As we exited the vehicle to take a better look, you could clearly see that the glass was broken from the inside, as if it was popped like a balloon. While no glass fell in the vehicle due to the shade being shut, there was glass all over the top that my husband had to clean up. Unfortunately due to no negligence on our part, we had to file an insurance claim.

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. I see there is an ignition switch recall on the 2019 and the 2020 cars but for some reason I don’t see my 2020 included in that. Now the proximity sensor is at fault and I have to take it to the dealer again. Please let me know what I should do

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.
