2017 Volkswagen Jetta: headlights failing or too dim

Filed Jul 22, 2025 · Driver assistance, Electrical · CA

I purchased my car used. In the past 3 years I have had problems my headlights became increasingly dim I checked my fuses and it had blown so I replaced it. Upon doing so my windshield wipers that had just been working no longer moved. But my headlights worked. Then my passenger window would not work with the drivers door controls. I can put it up but not down. I have never had the front collision warning work. Nor the lane departure the tire info used to work. Now it doesn’t. I toook my car into be caked and I was told that everything except the windows and wipers was fine. The wipers had a blown motor. Replaced it and they are good the window motors are dying? And need to be replaced. Also when in cruise control it will accelerate for just a second before slowing to the speed set at. Love the Volkswagens family has had four others and never had smyproblems

I am continually have issue with my headlights bi-xenon ds3 bulbs going out. I have replaced the ballast and the bulb w oem parts and the issue continues. My day runner LED lights work on the passenger side but the HID bulb does not work. I have no low beam. Everything else works. Same issue on drivers side until I replaced the entire housing unit. Regardless both lights DO NOT REFLECT IN DISTANCE making it EXTREMELY HARD TO SEE AT NIGHT forcing me to have to drive w my fog lights on just to see.

FRONT HEADLIGHT ASSEMBLY: 1) the HID HALOGEN lights- (a.) the main DS3 buld continues to burn out not lasting longer than a month. (b.) the ballast also than shorts out (c.) the HIGH BEAM does the reverse effect making everything black (d.) the LOW BEAM do not work right as i cannot see obstacles in the road clearly- WHEN DRIVING AT NIGHT; I ONLY HAVE MY FRONT DRIVERS SIDE HEADLIGHT AND FOG LIGHT ASSEMBLY TO DEPEND ON PRIMARILY. THE PASSENGER LIGHTS WHEN SOMEWHAT WORKING; ARE DIM AND WHEN THE HID BULB BURNS OUT- ALL I HAVE TO DEPEND ON (for that side of car) ARE MY DAY RUNNING AND FOR LIGHTS. 2.) FORWARD COLLISION WARNING SENORS ARE NOT WORKING MAKING IT TOO LATE IF OBSTACLES DETECTED 3.) THE DRIVERS SIDE SEAT WARMER STOPPED WORKING

Front left headlight has no power going to it. Rear right tail light has no power going to it. Third, brake light has no power going to it. Wind shield washer pump has no power going to it. Both rear doors do not lock. This issue is all connected with each other because it fixed itself. Once and they all came back on together and then it went back out.

A random notice appears on the dash display, "driver assistance button is disabled". Then windshield wipers randomly activate, door locks click locked and unlocked, and cruise control disables all while driving. High beams no longer function and occasionally all electric display, radio sound, and lights go black while driving. You must pull over, shut off the car, and wait approximately 5 minutes before restarting to recover to normal. Volkswagen service claims nothing is wrong with the car because it doesn't show up on the diagnostic report.

I havve been having electrical issues the past three-five months on this vehicle today when in a car accident the air bag lights came on but no air bags deployed fire and rescue siad they should have deployeed. The radio would turn on and off and sometimes the head lights wouldnt turn on.

Issue on zero intensity of the instruments gauge illumination during the daytime I have experienced the dimmed instrument gauges on my 2017 jetta and confirmed this is due to the automatic illumination adjustment feature of the model. This report covers only for the specific VIN, however, the issue is caused by the design, any model year jetta and the same design architecture models from vw will have the same issue. I have experienced the issue under bright sunlight while driving on the regular street, but a bit of shady area by nearby tree or building. Even I'm using the sunglasses due to the reflection of sun light or direction of the car facing to at that time. My 2017 jetta has light sensor in between a bit offset position of tachometer letter "7" and "8", that is about 1/4 inch or 5 mm diameter in size, and this sensor controls the illumination of both tachometer and speed gauge. (graphic lcd display and needles keeps the full brightness.) it will be dark if surrounding is dark and becomes bright if surrounding is brighter. This controls too much and becomes zero intensity is not acceptable according to the regulation "s5.3.2 brightness of illumination of controls and indicators" under "49 cfr 571.101 - standard no. 101; controls and displays." I did contact with vw of america to inform this issue, but customer care representative cannot do anything beyond diagnostic result at dealer that they are insisted the vehicle operated as spec. It is very simple to replicate the same issue at any location, without driving and without turn on the engine. It just simply covering the light sensor area by the palm or any cloth to imitate the darkness while ignition is on. It is even darker than illumination while headlight on at that time for experiment. Again, this is under the daylight.
