2016 Volkswagen Jetta: sudden loss of power

Filed Jan 18, 2026 · Engine, Transmission · AL

Car was great for first 100000 miles. Then it was not. While driving in heavy traffic on a three lane highway, car lost power, ability to accelerate and went into limp mode. EPC code went on. Very dangerous. Took it to several mechanics, VW dealerships, could find nothing wrong. Issue has happened over 100x since, but I am unable to afford another vehicle and pray over car continually to keep me and others on road safe. Few times car would suddenly shudder like engine was quitting. Canceled medical trip to city when this happened 50 miles from home. Have had to cancel work as well one day when this happened. Recently bought a FIXD sensor and it diagnosed issues with faulty gas cap and purge valve. Replaced both. That issue seems to have resolved. Car has been burning oil like crazy. Sometimes 1L after driving 150 miles. Fuel efficiency is terrible. Even running 91 grade fuel hasn't helped. In cold weather, around -30, sometimes driver door won't close. Literally have to drive with one hand holding steering wheel and one hand on door. Scary. Newest issue this week. While driving highway speed, low oil light flashed momentarily. Then speedometer and rpm gages quit. Then entire instrument cluster went black. Was almost at work, so prayed and got there safely. After work, instrument cluster worked, but car started and stalled immediately. Mechanic code reader pulls up nothing. My FIXD reader says it's a upstream oxygen sensor. Looking at youtube videos, the issue it describes sounds like this may have been what contributed to those EPC codes for last few years. Borrowing a vehicle from family - car is stranded at work. This is my first and likely last VW.

When driving the car, it will randomly stall, lose power or not accelerate. Sometimes the EPC light and oil light will illuminate other times it gives no warning. It shut off on the interstate while going 72mph. I have taken it to the dealership since a month after I got it and they keep telling me nothing is wrong with it. I have to get oil changes every month despite not driving it much and the gas consumption is 3tines what it should be. I’m having to fill the tank up three times a week despite going to and from work which is 9 miles from my home. I have taken it to the dealership and had to pay $1000s of dollars only for it to start having the same issues within a week

We purchased the car in May 2021, within a week, the check engine light, EPC and oil lamp became illuminated. Contacted dealership who "inspected" it and said "nothing was wrong and reset the lights." A few weeks go by and the same thing. We noticed the car was "stuttering" during acceleration. We attempted to bring it to the dealership they couldn't inspect our vehicle because they didn't have "availability". My husband brought it to a local mechanic who recommended bringing it to the dealership again because of the codes it was throwing. We scheduled an appt which was 4 months out. During that time the oil was changed every 1.5 months because the lights kept coming on. Moved to Mississippi and the issues became worse. The vehicle would seem to lose power while driving on the interstate causing a Semi to veer into the other lane because the car went from 70mph to 20mph in a matter of seconds. Brought it to VW of South MS, was told Timing case, sealant, rail, tensioner, gasket, and several other things were needed to be replaced. Was told the vehicle was burning oil, lower timing cover was replaced and found bolts from tensioner broken and metal shavings. Was charged over $2500. 1 week later same exact issues occurred again. Brought it in, reset lights told us "it's fine" Few weeks of the car not being driven, happens again. We bring it back and they inform us of an array of "new issues" charges us $2000 and within a week the car is back for the same exact issue. I reviewed the recalls but it is saying none of them apply to my vehicle but they are the exact things that are going on. It is unsafe to drive the car. My husband will not allow me to drive it out of fear that it will stall and result in a serious MVA. Why isn't VW doing anything about this issue? How many people have to get injured or killed for them to conduct an investigation for this issue?

While driving in the morning rush hour my vehicle lost power. As I pushed on the accelerator the vehicle did not speed up and maxed out at 40 mph. I was not able to keep up with the speed limit or traffic and I pulled over to the shoulder to get out of traffic so that I did not cause an accident. Dealer confirmed that my transmission had gone out. The check engine light came on.

This driver has been quoted for a new transmission by VW. There is an existing recall for 2013-2015 Jetta hybrids for the same symptoms as listed below. The issue was preceded by a check engine light and a service hybrid system light and inconsistent braking force that would often pose a system risk as regenerative braking would often stop working forcing the driver to quickly apply more pressure unexpectedly (almost resulting in front end accidents). Now , the car is jerky while stopping and still unpredictable in its application of brake force. When taking off from lights, occasionally the transmission will stop providing power from the hybrid system to the wheels forcing driver to stop and restart the car in the intersection resulting in near accidents. The car’s gas engine often will fail to start while driving resulting in a loss of power when the car’s hybrid battery is depleted. The driver has had to pull over to stop and restart the car. Failure to start often happens on first startup as well. The car will no longer remain in electric mode due to this issue and often cycles the engine on and off many times while sitting at red lights.

Seat belts no longer working except for the driver side. Passages side will not lock and pops out. All three back seat belts are stuck and will not release. I've had the car only a year purchased from drivetime. Then my key got stuck in my ignition and could not turn car off had to rush to dealership to find out the issues had to pay for something I have no control over. Then had issues with throttle position sensor, and trubo supercharger issues losing power. Almost was hit my a semi truck on the freeway for losing power to my car. These issues I feel have nothing to do with me a a customer to have to pay for only having the car a year. These issues are life threatening. I was forced to purchased gap and this extended warranty for nothing to be covered! This car is a lemon, especially when it has ignition and engine issues. The car is only 4 years old.
