My car consumes an over abundant amount of oil about 1 quart every 1000 to 1500 miles. There is a civil lawsuit right now about the piston rings having low tension and my car has every symptom of this. This could lead to turbo issues, and several thousands of dollars in repair costs. I’ve already had to replace my oil pan, timing cover, and pcv and the car only has 80,000 miles on it.

I am requesting that Volkswagen open a formal case regarding a fire involving my 2021 Volkswagen Passat. On May 6, 2026, at approximately 9:30 PM, after driving about seven miles, I came to a complete stop and the vehicle began smoking before catching fire. The vehicle has been declared a total loss and is currently being stored at a salvage yard pending investigation. I am requesting that Volkswagen investigate the cause of the fire and advise whether an inspection of the vehicle will be conducted.
NHTSA complaint #11742775 — an unverified report by a vehicle owner.
A major engineering and material design failure occurred involving internal fluid containment seals, resulting in a severe electrical safety hazard. Pressurized engine coolant breached an internal component seal and began migrating internally directly through the vehicle's engine wiring harness via capillary/siphoning action. The fluid used the sealed wiring loom as a literal pipeline, traveling inside the wire insulation to bypass all outer weather seals and completely flood the Engine Control Module (ECM) pin connectors. The vehicle's dealership service department documented extensive galvanic corrosion and shorting inside the primary vehicle computer pins due to this blue-green fluid pooling. Because the dealership has not yet completed the full repair, the exact originating component source of the leak (e.g., the engine coolant temperature sensor or the coolant expansion tank housing barrier) remains unconfirmed. However, the physical mechanism of the coolant migration through the sealed harness into the primary electrical architecture is fully verified. This defect presents a critical safety risk. The sudden flooding and short-circuiting of the Engine Control Module can cause an immediate and unexpected loss of engine propulsion, power steering assist, and electrical control while driving at highway speeds, creating an imminent risk of a high-speed collision.
NHTSA complaint #11741923 — an unverified report by a vehicle owner.
The vehicle experienced repeated catastrophic engine failures, including failure of a replacement engine. Approximately six months after purchase and at around 80,000 miles, the engine failed and required a complete engine replacement through Volkswagen and the MaxCare service contract. Approximately one to one and a half years later, at around 120,000 miles, the replacement engine also failed. The vehicle developed rough idle conditions, check engine light warnings, timing chain and camshaft-related issues, lubrication-related concerns, and severe engine performance problems. Volkswagen later recommended another complete engine rebuild or replacement along with additional engine-related repairs. The vehicle became non-operable and could no longer be safely or reliably driven. The repeated failure of both the original engine and replacement engine suggests an ongoing defect-related condition rather than normal wear or an isolated mechanical failure. The problems were confirmed and documented by Volkswagen service personnel. Similar engine-related concerns involving oil consumption, lubrication issues, timing system concerns, and engine performance problems are also reflected in Volkswagen Technical Service Bulletins involving this type of engine.

2020 Volkswagen Passat SE 2.0L VIN: [XXX] Complaint Summary: I am reporting a persistent and unresolved fault involving the secondary air injection system (DTC P0491 – insufficient airflow) that has resulted in repeated, conflicting diagnoses across multiple repair facilities. This raises concerns about a potential systemic defect affecting this vehicle model. Detailed Description: The issue began prior to March 2025 while the vehicle was still under warranty. The vehicle displayed a Check Engine Light associated with diagnostic trouble code P0491 (secondary air injection system insufficient airflow). On April 3, 2025, a repair facility diagnosed the issue as a failed secondary air injection pump and replaced the component. However, the Check Engine Light returned within 24 hours with the exact same fault code, indicating that the repair did not resolve the issue. A second independent diagnostic evaluation was performed later in April 2025. This inspection confirmed that: The secondary air injection pump was functioning correctly Airflow through the system was present Electrical controls and PCM commands were operating properly The fault was attributed instead to a mechanically stuck secondary air injection combination valve Despite this revised diagnosis, the issue has remained unresolved. As of 2026, a dealership evaluation has now attributed the same fault condition to a potential failure within the cylinder head assembly, indicating a significantly more serious underlying condition. Safety Concern: This issue involves the emissions and engine air management system and has resulted in: Persistent Check Engine Light Repeated failure of emissions-related components Conflicting and escalating repair diagnoses across multiple qualified service providers I am requesting that the National Highway Traffic Safety Administration review this issue for potential investigation into a systemic defect.

NHTSA complaint #11715843 — an unverified report by a vehicle owner.
I am reporting a recurring engine defect in a 2014 Volkswagen Passat that has resulted in repeated engine failure and loss of power while driving. Approximately six months after purchase, the vehicle required a complete engine replacement. One to two years after the replacement, the vehicle began exhibiting the same engine-related failures and has since become inoperable again. Manufacturer-issued Technical Service Bulletins addressing these engine defects were issued prior to the sale of the vehicle, indicating the condition was known. The repeated engine failures create unsafe driving conditions, including the risk of sudden loss of power during vehicle operation.

After recall 20AE (Fuel Pump Control Module) was completed at Performance Volkswagen in Lyndhurst, NJ, my vehicle began shutting off while idling and displayed code P0087 – Fuel Rail/System Pressure Too Low. This issue began immediately after the recall was done. On one of the first nights after the repair, my car suddenly shut off around 4 a.m. while I was in New York City, leaving me completely stranded in the middle of the street with no assistance and no warning lights beforehand. I was panicking, stuck alone in the dark, unable to restart the car until it was jumped. The next night, it happened again under the same conditions. The vehicle stalls randomly when stopped, creating a serious safety risk for both myself and others on the road. When I returned to the dealer, they refused to fix it under the recall and forced me to pay $220 under protest. Their own technician report shows they checked the fuel pump control module (the recalled component) but still claimed it was “operating as designed.” My independent mechanic confirmed the same fault code P0087, which clearly points to low fuel pressure and a failure of the recall component. This situation has caused significant distress, fear of driving, and ongoing safety concerns.

My vehicle is a MY2015 Passat TDI SEL with the EA288 (CVCA) diesel engine. Water Pump Failure Occurred at 99488 miles. Leaking coolant from underneath the engine and the expansion tank bottle became empty. Vehicle was parked after a quick 8 min drive to work from home in the morning (~8:45AM) and when I came back at 12PM around 1 quart of coolant had leaked out. Luckily I was not on the freeway or driving the vehicle where it would ride on its torque curve increasing probability of catastrophic failures even after there are usually software induced engine protection derates in place. Official service interval for water pump and timing belt on this engine is 130000 miles but there have been numerous field incidents of pre-mature water pump failures which can be very expensive to fix (~2500 USD). Volkswagen/Audi already have a class action lawsuit against them on their 2.0 TFSI (EA888) water pump failures and I'm wondering why their MY2015 2.0 TDI (EA288) diesel engine has not been investigated for the same. This engine was only available in certain MY2015 VW/Audi vehicles but just because the cumulative number of vehicles with this engine are lower does not mean that it shouldn't be investigated for a very similar manufacturing/design defect of the water pump. I would strongly urge NHTSA to do a similar investigation on this 2.0 TDI engine and hold the manufacturer accountable.
