general problems of the 2015 Volkswagen Passat

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 oxígen 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.

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).

The contact owns a 2015 Volkswagen Passat. The contact stated while veering left, the vehicle stalled. The battery lights was illuminated. A towing service was called who performed a diagnostic on the vehicle and stated the cause was not from the battery or the alternator. The contact drove the vehicle to the residence. The contact stated the failure recurred. The vehicle was taken to the dealer who performed a diagnostic, replaced the battery and serviced the cooling system. However, the failure persisted. The vehicle was taken back to the dealer who stated the fuel pump needed to be replaced. The manufacturer was not notified of the failure. The failure mileage was approximately 70,300.

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. My vehicle has been in the service dept of vw for over 6 months (this last time) because they cannot figure how to fix it permanently. Vw corporate is very aware of the situation and has fed me a bunch of bullshit not even a child would believe and has refused my suggestion to self report the problems to nthsa and carb. If the cars are not taken off the road this issue will definitely (if not already) result in major injuries and likely death. I have done my duty notifying this government agency and now if a tragedy occurs there will have been actual notice as required by the law.

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.

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.

Sluggish, hesitates, will not accelerate uphill. Codes: p039b, p93af, p03b9.

On two occasions, the vehicle's engine stopped working while the car was moving. The first instance, the car stalled while moving at 5mph on an expressway exit ramp. It restarted after 30 minutes (blocking traffic for that period of time). When attempting to restart, the motor would turn over, but the engine would not start - as if there was no gasoline. The second stall occurred while driving on an expressway at 55mph. In that case there was again a sudden loss of all power. However, the vehicle would not restart. The car was taken to a dealer on both occasions. The dealer replaced the batter on the first visit. On the second visit, the dealer claimed that there were fault codes related to the high pressure fuel rail that needed to be reset.

Fuel filler door opens intermittently. Not good when attempting to fill car with gas, and the door won't open. There is no manual release for this, and you would have to break parts to get to the fuel filler cap.

Engine failure due to fuel system failure. During driving complete engine shutdown. Will not restart, vehicle towed to dealership. This happened a second time within 2000 miles. Dealer states contaminated fuel both instances. Fuel was purchased at two separate gas stations each time. Costing 7000 dollars in repairs for each instance.

I got a recall notice regarding the cam issue with this vehicle. They are tell me the fix is to change the software in the ecm. However doing so will change the timing on my car which will affect the performance, gas mileage and emission that my pzev car puts out. Vw refuses to give me a straight answer on what they are changing. I believe that said changes will cause my vechile to pollute more and get worse mileage as they must be adjusting the timing to change the amount of vacuum the cam shaft makes.

With no warning car would not brake . Brake was stiff and would not go down , emergency brake had to be used which could of caused the car to spin out. This car was serviced for the matter at hand . This situation should never had happened it was hazardous ,life threating , and a total safety fail. My family and I were at risk because of this!.

Tl-the contact owns a 2015 Volkswagen Passat. The contact stated that while driving at approximately 70 mph, the fuel gage was providing inaccurate reading levels. The failure recurred numerous times. The vehicle was not taken to a dealer or diagnosed. The vehicle was not repaired. The manufacturer was not notified of the failure. The VIN was not provided. The approximate failure mileage was 6,000. Ak.
