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.

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.

I got into the car and went to open the rear doors for my two children and put them in the car. They got in the car and the door open alarm continued even after the door was closed. I reopened and closed the door and it finally stopped. The next time I opened the door the windows would not go down, the locks did not work and I could not adjust the mirrors. I went to the dealership and they have said it was the wiring harness between the door and the car. A wire had broken and they ordered a replacement harness. After investigating the issue, I see their are a lot of people with the 2006 vw Jetta tdi with the same issue. I see this as a safety issue, due to the fact that in an emergency I would struggle with exiting the car with my two children. It also means an exposed wire is a regular occurrence with the vehicle.

I recently purchased a used, low mileage 2006 vw Jetta and soon after I noticed the headliner began to bubble, sag, and tear away from the c-pillars I knew that this was not normal for a four-year-old car and that this could quickly turn into a safety hazard if left ignored. Should the headliner continue to bubble and sag into the driver's line of sight this could become a serious motor vehicle hazard. I began to read around online and discovered, to my shock, news about the commonality of this issue to hundreds of owners. So, surely Volkswagen is already aware that this is a mass isâ­sue and would certainly want to take action to correct it, right? I am writing because I genuinely love this car, but feel that there is a serious motor vehicle defect within the headliner assembly, glue or the way the fabric liner was cut, possibly too short. I want to get my headliner repaired, but honestly do not feel that I should be fully responsible for low quality craftsmanship put into the headliner of a four year old vehicle. I'd like for Volkswagen to petition to have this item recalled citing the potential safe hazards it can cause due to loss of sight while driving. Also, I'd like for you to contact me in order to make the proper arrangements to have mine replaced. I am also sending this letter to Volkswagens consumer complaints department, consumer affairs, and the national highway traffic safety administration for their review. The consumer stated within one week of owning the vehicle, he noticed a vibration in the steering wheel. It was determined the rotors needed to be replaced. Soon after, the radio and window buttons began to peel as if they had been sitting out in heat. Updated ivoq 12/22/jb the consumer also stated the wiring in the driver's side door was defective. The exterior side mirror turn signals did not function properly. The wiring harness inside the boot of the driver's door showed signs of wear. The consumer stated 2 out of the 11 wires were broken, including the ground wire. Updated 06/07/11.

I have a 2006. 5 vw Jetta tdi which I purchased new in summer 2006. Starting in sept 2010 we have had an endless problem with door ajar sensor. While driving the dome lights and ajar light come on and off constantly. The alarm system arms itself and goes off when parked and the sensors stop working. I have had both door sensors changed along withlatch assembly to no avail , now the shop indicates it is the wiring harness. Yesterday I received a letter from vw about other wiring harness problems associated with the side impact airbag system. (service action 97u3/t3) though they don't call it a recall.

The contact owns a 2005 Volkswagen Jetta. The contact stated that the wiring that extended from the alternator to the power distribution center burned, causing the battery's inability to hold a charge and the engine's inability to start successfully. The vehicle was taken to a repair shop where the wires were replaced. Also, the gauges on the instrument cluster failed; while driving, the contact noticed that the gauges were moving around and not stay steady. The mechanic also replaced the instrument cluster and reprogrammed the computer. The contact called the manufacturer who offered no assistance. The failure mileage was approximately 67,000.

There is a defect within the wiring harness that causes most of the vehicle electronics to shutdown and occasionally stops the vehicle while driving. I can provide pics of the wiring issue if needed. The issue usually occurred when driving in very wet conditions. After the first time it happened, the problem grew worse as the wiring was chafed more & more over time. The Jetta tdi's should be recalled to have the harness checked & repaired before someone dies in a car crash.

I drive a 2007 Jetta wolfsberg. In April 2010 I was leaving for work and the car wouldn't start. My husband went out and it started for him. No warning lights were on. A week later the car's engine just died while traveling 60mph on the freeway and would not start. Towed to dealership where they checked all the wiring harnesses and overlaid a wire. One day after receiving the car back I had trouble starting it again. Reported this to dealership service. Two days later the engine died while driving down a residential street and would not start. No warning lights were on. Towed back to service where they had a vw engineer look at the car. They ended up replacing the computer in the car. All service was covered under warranty. I have not had any problems since the computer was replaced. I am reporting this because of an article my aunt sent to me. The article said the government is investigating the same problem with other vw models (stalling, loss of power and engine).

Slight smell of smoke in 2001 vw Jetta while driving. Parked car at home and returned to car aprox. 30 minutes later to find cabin full of smoke/smoldering from area behind right rear seat. Disconnected battery positive terminal and put water on smoldering area to extinguish fire. 8-10 inch hole burned completely through right side of rear deck. Upon my initial inspection it appears to have initiated from the center brake light wiring.

I have a 2003 Jetta GLS. I had about 65k miles on it and the speedometer first fluctuated wildly then died, or appeared to be dead. It would randomly start working for a few days and often would die again while I was driving. Non functioning speedometer affects function of auto locking doors, odometer, trip computer, and related functions (they do not work when speedometer not working). My mechanic tested the vehicle speed sensor located on the transaxle. It is fine. I had the entire instrument panel replaced (to the tune of almost $700, $500 of which is for the part!). Now I am being told it may be a coolant migration issue similar to that of the my 99-01 cars. However there has been no TSB for 2003 Jettas and now my car is out of warranty. Replacing the wiring harness is a very expensive ($6k has been mentioned) repair. Internet research shows that my issue is not unique, many failed speedometers in this model year Jetta, although vw to date is silent w/customers.

I own a 2001 vw Jetta GLS vr6. Since I have owned this car I have had problems with it. I am a young woman in the military and am in full time school, so I don't have the money to run around and fix it as much as I have been forced to do. First my gas gauge went out three months after buying it $600(under warranty) then a month later O2 sensor $300(non warranty). Then it was the catalytic converter$1500(non warranty) wiring system$1000(of course non warranty) windows wont roll up without rolling down again and sometimes get stuck$700(non warranty) cruise control went out$845 (non warranty), windshield wiper motor. . . Stationed in alaska and couldn't go without that $750(non warranty) now my secondary air pump is out and I was quoted $1294 from private mechanic and $1400 from vw. Also the cruise is still out and the windows are doing the same again. I have talked to many people in the same boat I have been in with so many repairs. Is there anything that can be done to stop vw from making faulty parts and charging an arm and a leg? I feel though that if it is brought up to you that my voice will be heard, because when I call the volkwagen customer service and complaints I get nowhere.

I turned on the driver's seat heater to 5 (highest setting) on my 2003 vw Jetta tdi when leaving my house at 7 am. I used this regularly to warm the seat for a few minutes on cold mornings, then would turn it off (lower settings never produced noticeable heat). Within one minute I felt a burning/electrical sensation in my upper left thigh. I was driving on a mountain road and the pain made me jump in my seat and nearly lose control of the car. I pulled over and turned off the seat heater (having heard of problems with the heater). The leather seat had a blister about the size of a cigarette burn but had not burned completely through. While I stopped the heater before it burned through the seat (and my pants), the real danger was in a possible accident from the burn/shock that caused me to momentarily lose control of the car. The seat heater is no longer safe to operate. My understanding from reading similar posts here and elsewhere is that the wiring is now broken in the seat (and many have had it break in the same spot). If I had not guessed the source of the problem quickly, or if someone were to unknowingly use the heat setter in the future, it could lead to a serious accident, personal injury, and car fire. Similarly, this poses a serious risk for other drivers of these vehicles who may not be aware of the problem and react too late. I request that the NHTSA urge vw of America to issue a recall on this dangerous and pervasive problem (many reports here and elsewhere, such as tdiclub. Com and vwvortex. Com). Vw has issued a recall on this problem in canada but not in the u. S. They also have a voluntary repair for passats of similar years, but not Jettas or golfs. Thank you.
