After having the government approved and MANDATED Phase 1 and 2 Dieselgate fixes performed on my VW Passat TDI it has randomly lost power and or stalled while at highway speeds at least 6 times. The last time my 16 year old son was left stranded in the middle of a busy four lane highway narrowly avoiding being hit and seriously injured and/or killed. Apparently there are thousands of these cases (a class action lawsuit filed in 2018) on the road. Why haven't I been notified? This mandatory fix is much more dangerous then the original issue it seeks to address. From what I understand, the fix is causing the DPF regeneration sequence to occur much more often and much hotter, thereby cooking/melting/boiling the entire cooling system and shutting the engine down without warning. …
The contact owns a 2015 Volkswagen Passat. The contact stated that while driving at various speeds, the vehicle sputtered intermittently. The vehicle was taken to the dealer, who diagnosed the vehicle and determined that fuel was leaking into the engine compartment, causing engine failure. The contact stated that the dealer had repaired the vehicle and possibly cleaned the engine. The dealer had informed the contact that the engine would last 4-6 months before complete engine failure. The vehicle was returned to the contact; however, while driving approximately 35 MPH, the vehicle sputtered and then lost power. The vehicle was restarted after several attempts to continue driving. The vehicle was returned to the dealer but was not repaired. The dealer suggested that a new vehicle be purchased. …
Mice and rodents just love eating various electrical wires, vacuum lines, diesel fuel lines (both from tank to engine & return lines), etc. Never once had any animals issues with my other vehicles. Discovered that VWoA thought it would be a brilliant idea to use Soy in the manufacturing of electrical insulation, fuel hoses, vacuum lines, etc. ANIMALS LIKE EATING SOY. Very frustrating. My vehicle has been disabled before and one time I sprang a nice leak, leaving a trail of diesel behind me. Since all repairs and parts were ordered and conducted at local VW dealership. All records are both on carfax & stored in VWoA servers.
Looks like the plastic the fuel pump housing is made out of is low quality or prone to degradation by fuel. Hairline cracks have formed on the fuel pump housing causing fuel to leak when the pump is pressurized and running. In my case a pin hole also appeared causing the leak to be quite significant. When reviewing the attached image. Most the major looking hairline cracks seep fuel. The pin hole can't really be seen in that image but is located in the middle of the raised lettering that starts with a "C" (in between M and E) (I have a video of it)
While driving on the highway my car suddenly began to stall. It lost power later after that & when I got an oil change then tried to drive it later I was stopped by another driver told something is leaking. While driving to a Autozone I noticed the gears jump while shifting from 1 to 2 and I now can't past 20 mph. I've already gotten the camshaft replaced and while researching I learned my cars make and model is being recalled for everything my car is going through. The vin says it's not eligible for any recalls. Its maintenance is unkept.
Gas and Oil comsumption is way too high ... Almost every 600-1000 the low oil lights turns on! Check engine on almost all the time due to an error with the ox gen sensor. EPC light gets on very frequently and the car loses speed. Also vehicle has a constant rattlesnake sound when speed is low. Issue was reported some years ago to a local VW dealership in Georgia but they never took care of the issue. Ongoing for a couple of years!. No additional details
Engine time chain skipped. Fuel rail leak from regulator(dangerous to drive as it can catch on fire). Suspension problem car shakes over 40mph(alignment and balance did not help), problem due to coils or other components. Mechanic shop checked car and they denied to work on it due to fuel recall.
The car went 8 blocks 35mph the engine started shaking, I was stopping at the red light the car surging forward with my foot on brake engine still shaking. This all happened in 3 minutes. No lights on dashboard, the rpm dropped from 2,000 to 1,000 and then everything was ok.
