2021 VOLKSWAGEN TIGUAN Complaints

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.

The J949 SOS emergency communication unit failed, disabling vehicle 911 automatic crash notifications and emergency response capabilities.” NHTSA opens defect investigations based on consumer complaint clusters for this exact failure pattern.

Known issues with Tiguan models of overconsumption of motor oil due to faulty engineering of top(head) of engine.

Taking left turns is dangerous. My turn very slowly and Hard press on pedal to turn. Oil consumption is insane. Started at 38k miles, manufacture warranty ended after 4 years. I’m under 52k miles now and have to fill oil about every 1k miles. I’ve had 4 oil changes this year alone. I’m regular about Maintenence. Last oil change was 08/03/26 check oil light came on 8/15 had to add 3.5 quarts 8/26/26 Will keep track of each time I need to add oil and update here. This has been an issue for many Tiguan owners where is the recall???

Noticed the check engine oil light started coming on periodically between oil changes 3-4 years ago, but no external or noticeable oil leaks. Was told by VW multiple times it’s standard for VWs to burn oil. I started having to top off oil much more frequently over the last year, 1 quart per 1000 miles. The check engine oil light would turn on every month at random times while driving. Took my car to a shop; they removed 02 Sensor 1 and borescoped the exhaust system. Found oil leaks from valve seals, leaking into the exhaust manifold. A few weeks later, the check engine light came on for the first time (codes: P24D6 and U3501). Brought car to another shop; they scanned the car and the following codes were found: U350100 (Passive/Sporadic) - Control Module Input Power "A" Circuit Low U041600 (Passive/Sporatic) - Invalid data received from vehicle dynamics control module) P003000 (Passive/Sporatic) - O2 Sensor Heater Control Circuit Bank 1 Sensor 1 U105400 (Passive/Sporadic) - Information electronics 1 control unit No communication P24D600 (Passive/Sporadic) - Evaporative Emission (EVAP) system pressure sensor/switch B circuit range performance. The second shop also stated the valve stem seals needed to be replaced in addition to the Upstream Oxygen sensor and PCV valve. The car was brought to Volkswagen for repair under the extended warranty. Volkswagen confirmed the PCV valve and valve stem seals were bad and needed to be replaced. VW also noted smoke coming from the exhaust. The vehicle has 53k miles on it.

Vehicle abruptly lost power on the highway and limited itself to 3000 RPM. PCV valve failed and oil pan cracked at only 45k vehicle miles.

PCV value/oil leak is a known issue with this specific model of car. The repair I was quited was over $2700 when the car is just out of warranty. There was no oil light indication showing that the oil was low! I only checked everything out because I saw oil in the drive way. The car read zero oil on the dip stick. I added 4 quarts and finallt started to get into operating range. My wife drives this car and could have been in a major accident if it hadn't been noticed.

My name is [XXX], and I am writing today to express my complete frustration mentally and financially with a CPO 2021 Volkswagen Tiguan (VIN [XXX]) I purchased XXX. To date my vehicle has been in for service multiple times – countless times for an issue with the infotainment system and driver warning indicators that is still unresolved and again for months waiting on a new engine due to an oil consumption issue that was finally resolved November of 2025 (Case XXX). My recent service visit on XXX was due to a “12 v battery not charging” error message. The vehicle was immediately taken to VW of [XXX] where we were advised it would be 3 weeks before my vehicle would even be looked at (which is atrocious) and not to drive it because further damage would be caused with no alternative solution offered for transportation. I then had the vehicle towed to a repair shop where I was advised the alternator “fried a 400-amp fuse and killed the battery, which should not happen, especially on a vehicle that has less than 50,000 miles on the odometer.” I paid $1,605.37 for a new alternator, 400-amp fuse and battery. Completely appalling and disappointing considering I take excellent care of my vehicle and it is supposedly an inspected, certified pre-owned vehicle – that’s a lemon in my opinion! I am seeking reimbursement for this huge expense for a vehicle that should not have these issues! I look forward to a resolve to this urgent complaint.

My Tiguan leaks and burns oil like crazy. Now it has 111k miles on it, but this has been an ongoing issue for the last five years since I've had it. I now have to put a quart of oil in every 100 miles. This is not the fault of me getting an oil change, this is a persistent problem caused by the manufacturing of the car. I have had the engine nearly seize up while driving on the freeway due to low oil from this issue. Please investigate and fix.

Electrical screen fail. Makes backup camera turn black and turns off while using. off and on repeatedly while in use. Very dangerous.
