My family and I have been VW owners for over 60 years. Unfortunately, the 2006 VW Passat has been layered with defects, negligent manufacturing issues, faulty wiring, electrical problems, computer glitches, to mention a few. There have been many recalls including an official recall by the NHTSA, for steering linkage problems and tie rod assembly which caused a loss of steering, crashes and deaths. Over 292 complaints are filed with Consumer Affairs, over 561 defects reported, and thousands of horror stories like mine about this car. It's considered a lemon by many car professionals. Many dealerships in the USA offered to inspect, and replace the electronic steering column lock free of charge and address any other concerns, which should be standard, reasonable behavior for all VW dealerships, mandated by this Federal agency. …

"in relation to fuel pump recall"....since the year started my car has been hesitant to start and sometimes needs a second start. On January 9th I started my car up in the morning and about 3 symbols popped: the gas cap, engine check, and the warning symbols. I turned it off securing my gas cap and waited a few mins and turned it back on. Now the engine check is gone so I continue my morning commute. Eventually the gas cap symbol is off, warning is still on but now the engine check is back on so I went to get it checked out at advance auto parts with emission and leakage codes identified. So then I bring it to a local shop who specializes in vw and they tell me I have fuel, oil, and coolant leakage. They cant fix the fuel leak but the other two is fixable which only brings to me concern about this recent recall. …
Tl* the contact owns a 2006 Volkswagen Passat. While driving 5 MPH out of the driveway, the vehicle stalled and the check engine warning indicator illuminated. The vehicle was able to restart and operate with no further issues. Upon returning home and driving back into the driveway, the vehicle stalled again. The vehicle was taken to an independent mechanic where it was diagnosed with a malfunctioning throttle body that needed replacement. The contact stated that the throttle body was replaced. The vehicle was taken to mcdaniels Volkswagen, 440 killian rd, columbia, sc 29203, [phone]) for reprogramming. The dealer stated that they could not reprogram the throttle body due to it being a used part. The contact then purchased another throttle body online. Upon taking the vehicle back to the dealer, the contact was informed that the computer needed replacement. …
It's common knowledge that the 2006 3.6l v6 engines have a terrible flaw. The oil pump bolt installed from the vw factory was either specified incorrectly, installed wrong, or has some other fatal defect. My wife drives less than 10 miles to and from work everyday conservatively. While driving 30 MPH the engine lost power started smoking and leaking oil all over the ground. The check engine light came on. We got misfiring codes so we immediately parked and had it towed to a local vw dealer. The dealer said the loose bolt & chain rubbing was what caused an internal failure so we'd need a new engine @ $4,554.00! The car has driven perfectly and is serviced regularly but suddenly died due to no fault of my wife or myself. …
While driving a 2006 Passat 3.6l, the oil pressure warning came on. Took to vw of orland park il.they told me the oil pump bolt is backing out, it hasn't yet, but it will, it's a common problem. They reccomended a new oil pump, bolt included, and new timing kit as that would have suffered residual damage from the bolt backing out. They offered to do this for $6000. A new engine for $11,000. Being disgruntled, the lead tech supervisor pulled me to the side and said this bolt was fixed in late 2007 models. I asked him how much to just replace the bolt. He told me $3000 + $12.00 for the bolt. I couldn't afford the repair. Vw offered no goodwill for issue. Every time car is started, oil pressure warning sounds and then goes off, no check engine lights ever come on. No weird sounds. Car is not being driven now. Vw is aware of this issue and has done nothing. …
