Volkswagen Tiguan tire blowout problems

Filed Sep 16, 2026 · Engine · MA

At approximately 53,876 miles, my 2021 Volkswagen Tiguan experienced a severe, premature failure of the Positive Crankcase Ventilation (PCV) valve / oil separator assembly. The failure of this component caused an immediate, dangerous buildup of internal crankcase over-pressurization. Because the excess pressure could not vent safely, it caused a catastrophic domino effect through the engine block, structurally blowing out multiple critical engine gaskets and rubber oil seals. Furthermore, the extreme downward pressure physically cracked the factory-installed composite plastic oil pan, leading to an immediate and rapid engine oil leak. A sudden and rapid loss of engine oil and internal oil pressure while operating a vehicle at highway speeds poses an extreme safety hazard. Had the oil pressure dropped completely while driving with my children in the vehicle, it could have resulted in a sudden engine seizure, sudden loss of motive power, or complete engine failure on a live highway, placing my family and surrounding drivers in imminent danger of a high-speed collision. Volkswagen is aware of this engine design defect, as evidenced by active internal Technical Service Bulletins (TSBs) and a pending federal class-action lawsuit (Reece v. Volkswagen Group of America, Inc.) detailing identical PCV-induced seal and plastic oil pan failures in the exact same model year. Volkswagen's failure to issue a safety recall for this unlisted "lifetime" part forces families to drive under the threat of sudden component blowout and subsequent engine failure. A mandatory safety investigation and recall are required to address this systemic powertrain defect.

Like many others, at 55k miles, our oil separator malfunctioned causing our oil pan to crack and dump every drop of oil. We had to replace the oil pan and fortunately our mechanic friend figured out it was the new pcv valve malfunction causing too much pressure in the engine. My wife was luckily pulling onto our property when the car essentially shut itself off. When searching for the valve I needed, talking to multiple parts dealers and then a vw tech, none of them are sure why there’s no recall. It happens between 50-60k to THOUSANDS of people now. Then I watched videos on the issue and the mechanics online are all saying the same thing- this should’ve been a recall 2 years ago and are all asking the same question. It’s time VW does what’s right. It’s awfully coincidental that they installed plastic oil pans that would crack and leak under instead pressure, rather than a blowout seals because of the valve failure.

Here is a quick description of the issue from our Volkswagon of Huntington service report. We have had this ongoing issue for a few months now. the check engine light will come on. We get it checked, we replace a sensor, and all is good for a day or week. Then we do it again, replacing a different sensor. Now the dealer is saying the oil separator is leaking and requires repairs starting at $8,400 and going up from there as they uncover more. We have always maintained the car properly. From research this appears to be a very known issue with this model car and should be reported and covered by VW. SCANNED VEHICLE AND FOUND FAULTS PRESENT FOR SECONDARY AIR. OBSERVED OIL SEPARATOR LEAKING CUASING UPPER TIMING COVER GASKETS TO BLOW OUT ALLOWING OIL TO ESCAPE. FOUND SECONDARY AIR PORTS IN CYLINDER HEAD CLOGGED TRIGGERING CHECK ENGINE LIGHT. ADVISED TO REPLACE OIL SEPARATOR,CAM SHAFT MAGNETS AND CYLINDER HEAD TO START. APPROX $ 8480.00 PLUS TAX

Was driving on highway at 74 mph when the vehicles loss of air warning light came on. Five seconds later, I heard a pop which caused me to lose slight control of suv. Managed to pull safely over to the right side of highway where I managed to put on the spare tire. Luckily there was no other car to our right when the tire blew if not we would have hit another car and the incident could have been much worse. The tire was taken to two Volkswagen dealerships and they found no signs of nails or glass. It is unknown what caused the tire to rupture in such a way that it left multiple holes and cracks on the tire. The tire size is 255/45 R19 100H M+S

Daughter was driving at roughly 20 miles an hour when right front suspension collapsed causing her to lose control and striking a parked vehicle. Lower part of strut that connects to drive shaft was sheared in half causing complete loss of steering. The tire was pushed back against the the fender well which in my estimation caused tire to blow. Parts are available for inspection. A tire blow out at that speed should not cause strut to break and impact on parked car was minimal. Failed component has not been inspected by anyone. There was no warning of any issue. I did complain to dealer of slight suspension noise while turning but they could not find any issues.

I had a tire blowout on the highway and caused my airbags to go off without having impact on my vehicle. The airbags going off was extremely dangerous and could of caused serious harm to me or someone else by possibly crashing into another vehicle. I luckily managed to keep my car in control with minimal damage to the body. The dealer inspected and other than replacing tire and alignments is the 10,000 charge for airbags and seatbelt fixing. There were no warnings by the vehicle before incident.

Tires had 17,000 miles on them. Tire pressure was checked 6 days prior to tire failure. Tire failure occurred on 3/11/23. My 19 year old daughter and two friends were driving on I-26 just east of Columbia, SC, when the tire sidewalls spontaneously failed. The TPMS is functional and never alerted the driver to low tire pressure. I contacted Continental Tire and provided them photos, and they have brushed it off saying that the tire was driven with low tire pressure. Continental Tire recalled 94,000 tires during the same time frame that these tires were manufactured due to sidewall failures. As noted in my correspondence with Continental Tire, there was a hairline crack in the rim which Discount Tire said may have caused the low tire pressure. The TPMS did not go off - the crack in the rim was a result of my 19 year old daughter trying to get to safety while driving at 70 MPH on I-26.

This car is not even 6 months old and while driving on a highway the tire blew, my car fishtailed and I hit a guardrail. The tire is shredded. I took it to a tire shop the same night and they said this is not what typically happens to a tire.
