I am unable to carry rear passengers (adults or kids) as the rear door do not operate consistently. I consider this a major safety concern. Dealer wants a large amount of money to replace two rear wiring harness as well as the electronic door actuators. This seems to be improper lack in the wiring harness to the rear doors. I have never had so many electrical problems with a vehicle is short a period of time. This really needs to be address so that nobody is injured form a door that will not open from the outside or inside, inconstantly. I will hold both NHTSA as well as vw if a tragic event does unfortunately does occur. This item has been posted numerous time in ve formus. My Jetta tdi has 156k miles, and it makes no difference to weather or time of day. This is a persistent problem that does not ever go away. Please investigate this major safety consern.

Rear electric doors will unlock consistently. Dealer ran diagnostic which points to a faulty wiring harness. This seems like a production issues and needs to be corrected. End result rear doors can not be opened unless you use the inside door lever. First responders or good samaritans will not be able to pull people from the rear passenger area. This happens intermittently vw forums cite similar problems.

My vehicle has had previous electrical issues as they pertain to the driver side door and window and its connection to its power draw and battery. In 2014, there was an extended warranty placed on my particular vehicle for replacement and repair of the window/door motor mechanics and wiring harness. I am now experiencing recurring issues and my brand new battery's charge will not hold - often beyond 24 hours as a failure is causing a power draw to drain the car's battery.

On September 21, 2015, at approximately 8:00 am in the morning, my seat warmers had burnt out. I was on my way to work; it was a chilly morning so I turned the seat warmer on to 4. The highest it goes up to is 5. Soon after, I felt it was a bit too hot. When I looked down, I saw smoke! I could not stop anywhere so I immediately turned off the seat warmer. I remained calm until I arrived to a stop light. When I looked behind me I noticed 3 holes in my seat. Two little ones and one big one. You can see the burnt wires. I was so angry by the time I got to work. I drove over to vw nemer in latham, NY to have them check it out and make sure there was no engine problem. The service rep. Was not sympathetic and not very polite. He kept saying I should have called and I should have made an appointment. I told him I was going to stay there and wait to find out the results. He came back to tell me that the seat warmer burnt out and that was all. He also tried to get me to fix my brakes (I did not come in for brakes). He told me I would need new wiring and seat covers (leather) to fix it. I had an extended warranty and had to pay a $100 deductible. I am not paying that deductible. However, it does not matter, because for some reason my warranty expired, but my car has not reached 100,000 miles yet. . . I have written a complaint to vw demanding some type of resolution. They need to check their cars very thoroughly. I read that there was another seat warmer incident that happened in canada and vw did not take responsibility for it. I am afraid to turn on any heating system in the car now, because it too might fail and shock me. I have pictures to show my torn seats. I can send them if needed.

Drove the car in the afternoon and parked it at an office building. Got back into my car about an hour later and when the car turned on, the radio was completely black. Nothing worked and would not turn back on. Checked fuses and they seemed to be fine. Took it into the dealer and after several hours of looking at it, they said there was something wrong with the radio wiring and there was no way to fix it with a new part and the only parts available were refurbished parts for at least the sale of $600+! this is a ridiculous amount of money for just a radio I think when there are parts cheaper after market. I only had the car for almost 5 years, it shouldn't have these problems so soon!.

Failure Date: 10/15/2014

A key feature of this vehicle is the capability for hands free use of on-board communications systems which is mandatory in several states for increased safety while driving. This capability is controlled through the factory installed radio system and blue tooth technology. When the oem radio fails the hands free safe communications system fails. This can result in a major safety concern. The radio installed in this vehicle failed with a pronounced pop indicating an electrical fault and will not operate. The radio is wired through other connections in the wiring harness to the vehicle information system above the steering wheel which includes operation data including miles per hour among others. Since this is an apparent electrical defect and is tied to other vehicle operation system information it becomes a major safety concern. Other owners have reported that their vehicles of this make and model have experienced related problems including failure to start and engine turning off intermittently. Volkswagen does not consider this fault a safety concern. These vehicles should be recalled to correct this deficiency at no charge tot he customer.

The wiring harness of the driver's door failed, which prevents the left turn signal, windows, door locks and gas fill door from functioning. The car becomes unsafe since the left signal will not work and the window will not operate so the driver can do a manual signal. Vw has issued a service bulletin on the issue stating that the original wiring harness is too short and breaks causing this issue, but they refuse to recall the car and fix the problem. A class action lawsuit has been filed on this issue, and is close to settlement, but will only cover cars less than 8. 5 years old. Most of the cars effected by this issue, 2005 and 2006 model years, are older than 8. 5 years so vw will not fix them. The following youtube video demonstrates all of these issues, please view it for full details: www. Youtube. . Read more...

The wiring harness in the passenger front door has broken. The windows, locks, and blinker on mirror do not work at all or will work sporadically and the airbag light in the dash turned on indicating the airbags are disabled. A mechanic confirmed it was the wiring harness and it was temporarily fixed so the windows could be rolled up to prevent any damage inside from snow and rain. I received a letter from a settlement company in regards to the wiring harness needing to be replaced. The letter states ". . The left front (driver's side) door or any wiring or connectors that needed to be replaced when replacing such wiring harness,. . . " I called the number to ask about the replacement of my wiring harness, and was told because it was the passenger door it did not meet the qualifications. I have since researched the recalls on the 2006 vw Jetta wiring harness and what I was able to find, it did not specify a particular side, but stated the Jetta's made in that year where manufactured with the wiring harnesses being to short, causing the wires to break. This is what has happened to mine. Any information regarding if I meet any guidelines to have this fixed with no cost to me would be greatly appreciated. The safety of my son and I is very important. Thank you for your time.

Wire harness in both front doors are broken due to short wires and the purge valve is also broken and the over head light is faulty and I feel like the 2005 -2006 Volkswagen Jetta 2. 5 should be recalled due to faulty wiring in the vehicle and Volkswagen is aware of the problem but will not resolve the issue and I think they should at least fix the problem for the consumer. I hope someone investigate this issue ASAP!!!!.

Leaving work I had started my car let the car idle down put it in drive and it slammed into gear after taking off the car shifted into 3rd gear and no higher after noticing this I pulled over put the car in park and tried shifting through the gears and it continued to slam into drive and reverse so I turned the vehicle off and started it back up at that point the mil was on and the service wrench was light up. Called me dealership they had the car towed to a Volkswagen dealership upon their diagnoses they said it could be a wiring issue possible a transmission control module issue upon further investigation the transmission control module had been warrantied previously (as I am the second owner of the car).

All electronic components in drivers door ceased to function. Auto door lock, driver's window, gas latch. Could not open driver's window. Apparently the orignal design of wire harness was defective in that it was 80 mm too short. Vw has issue a technical service bulletin on April 20, 2011 (v97-11-04) identifying this inherent defect. Dealer replaced driver's door wiring harness after diagnosising multiple broken wires. Vw will not reimburse car owners for repair/replacement.

I have run into numerous issues on my car that have caused me to troubleshoot and solve these problems. Multiple times I have pulled back the abrasion protection on the wiring and found that the insulation common to the wires is crack or worn off exposing the center conductor of the wires. Many times there are numerous wires within a harness that are worn through. So far I haven't found any that are shorted out but many are very close and at high risk of causing an electrical short/fire. I am an aircraft electrician/inspector and have found the abrasion protection to be horrible inadequate. There are 2 harnesses that go to the turbo that have a hard plastic abrasion cover but nothing shielding the wire from this cover. On both of these harnesses I found that the plastic had worn a series of ridges down the entire length of wire they covered and exposed the conductor in multiple places. My right hand mirror turn signal was not working so I pulled it out and tested the bulb and found that it was good. When I pulled the rubber boot that covers the wires in the door jam I found a power wire in there that the insulation had cracked and pulled apart exposing . 150" of center conductor in multiple places. It seems that the majority of the wiring is either poor quality or just not protected causing the insulation to fail and become a major safety hazard for potential electrical shorts or fires. I have heard these cars are prone to electrical caused fires and strongly believe that something needs to be done in order to avoid more very serious problems with these cars that could cost someone their life. I have only owned this car since may of 2013 and have already repaired 4 wiring harnesses throughout the car. This is something that should never happen on a car that is only 7 years old.

Engine light and ecm (engine control malfunction) light both come on. Have taken this new car in 6 times in 2 years, and the lights are on, yet again. After vw replaced sensors (four times), and wiring (module), and harness. . . . All under warranty, this is still a problem. And I do not know if it is a safety defect or not. I want to know that before a crash, fire, or fatality happens. Please. . . . If this is happening to your vehicle, make it known to this site. Thanks.

Sometime in early to mid 2013, I received a notice from Volkswagen that I needed to bring my 2005 Jetta in to have the driver's seat wiring harness repaired due to a recall. I had no prior problems with the air bags or warning lights. I took the vehicle in and they did the work. Within a few days, I got an error message in the display that there was a failure with the air bags. I took the vehicle back to Volkswagen. I was told that the technician failed to clear something in the computer memory so the failure message had come on. They indicated they cleared the message and the air bag light on the display did go off. A few months later, the air bag error message came on again. I tool the car back to Volkswagen. This time they said it was not related to the wiring harness and I would have to pay to have a new driver's seat side airbag installed, at a cost of about $700. In November 2013 I corresponded with Volkswagen and complained about the issue because I had no problems until they replaced the wiring harness. Volkswagen's response was that, even though I had brought the vehicle in for recalls on "a campaign related to airbag connectors and wiring", it was now the airbag itself that was bad not the connectors or wiring, so they would not repair it. The airbag light on the display is still there.

The seal between the connectors and the drain hose for the sunroof drains leak (three of four connectors), allowing water to run down the both driver and passenger side a-pillars. This resulted in the airbag and its associated mounts/wiring and harness getting soaked. The water continued down the a pillars to collect in the front wheel wells. The path of the water was over/through the drivers side interior junction/fuze block. The rear drains also leak, causing intermittent electrical malfunctions. Note that this leak is not due to the drains being blocked. Rather the seals between the white plastic that connects to the drain and the brown drain hose is not complete. This allows water to drip down onto the frame. As much as 2-3 gallons of water could enter during a mild rain storm.

Car has had issues 4k on. Car would accelerate on its own from 70 mph to 75 like wide open throttle. Car will quit at highway speeds 70 mph (no power steering, no brakes, just the service engine now and glowplug light are on flashing,(50k on) this has happened 4 times, car will quit making a right hand turn hitting pothole (50k on). Total dpf system has been changed out two times from two dealers , 3 total with original. Erratic egr signal was always tripping check engine light, some faults but not all are exhaust gas recirc flow insufficient detected sporadic, cylinder 2 injector n31 open circuit sporadic, exhaust aftertreatment fuel supply control performance sporadic, throttle actuator control motor circuit range/performance sporadic, navigation antenna (gps) short to earth. Dealers have spent over 20 thousand dollars parts and labor, in 4 different shops over 83 days (overnight), over 95 including reading codes only. Out of warranty expenditures over 1 thousand dollars so far. 69,000 miles and the dealer tech has no idea how to fix this car, he started out saying he has never seen a car he can't fix. I have over 50 pages of dealer documented faults and repairs, reprogramming ecu, was replaced this year to see if that would fix problems, some gone but now major issues listed above are happening. Replaced diesel particulate filter 2 times, replaced O2 sensors, replaced egr sensors and gaskets 2 times, replace throttle position sensor, replaced pressure sensor. Only item not replaced is the wiring harness.
