2021 Volkswagen Tiguan

On April 19, 2026, my 2021 VW Tiguan experienced a sudden loud gunshot-like sounding noise and my sunroof exploded. I fortunately had the screen closed, but large pieces of glass fell and were caught by the screen. It endangered me and my 3 children in the car. It was extremely stressful, as I was worried the entire sunroof would collapse on us and I was traveling at a high rate of speed. After pulling to the side of the road, further inspection showed the glass protruding upward. No sign of a rock or anything. There was absolutely no warning. I have filed a claim with insurance and plan to call VW tomorrow.

Engine has excessive oil consumption. Low oil indicator light will come on and Engine oil needs to be topped and added about every 2500 miles sometimes more often depending on driving conditions.

Oil consumption issue. The vehicle is experiencing blue / white smoke from tailpipe when starting also lost of oil due to a valve seal issue with engine that requires dealers to remove head and service it

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

After oil changes (always maintained at dealerships) it would require a quart of oil with in 2 days. Random starts will blow smoke out the rear. random sluggish behavior. Dealership confirmed PCV valve is causing a buildup in engine pressure which caused a premature oil pan gasket leak. Without full teardown cannot know full extent of damages caused. (which spills out of the bottom and towards tires.....) dealership and fellow Tiguan owners have all reported the same issue! with a repair cost of $1,000-8,000+. same with alot of other years as well.. The date below that i will list is for when the problem was fully confirmed (89k miles) but has always been an issue told its fine ... really noticed it after (68k miles) when i purchased the vehicle. With how many people are dealing with this it is hard to understand how we dont see an open recall for them..... also dealer said pvc valves are on back order and have been. why should one replace with oem if they won't acknowledge its a faulty part?

The contact owns a 2021 Volkswagen Tiguan. The contact stated that while his wife was driving slowly in traffic, several unknown warning lights illuminated orange, and the speedometer and RPM went to zero. In addition, the vehicle failed to accelerate as intended while depressing the accelerator pedal. The contact stated that minutes later, the vehicle returned to function as intended. The contact's wife stated that after several minutes, the lights and indicators returned to normal function. A short while later, the failure reoccurred, and the vehicle failed to accelerate as intended while depressing the accelerator pedal. The vehicle then returned to function as intended. The contact stated that on a separate occasion, the driver’s side door failed to open. While using the key fob, the doors failed to open. The contact's wife tested the door, and the only door that opened was the rear passenger’s side door. The contact's wife opened the driver’s side door manually. The vehicle then failed to start. No warning lights were illuminated. The vehicle was not taken to the dealer or an independent mechanic. The vehicle was not repaired. Three hours later, when the contact arrived at the residence, the contact was able to start the vehicle, the doors opened as intended, and the contact was able to drive around the neighborhood. The manufacturer was not notified of the failure. The failure mileage was approximately 29,180.

Wipers randomly start when switch is turned off. Wipers will randomly not start when wipers are turned on. Safety of others is affected due to visibility being obscured due to wipers not turning on. Injuries can occur when wipers randomly start. There was no warning prior to the problem starting.

My fuel system level indicator does not work properly when the tank is below 1/2 full, and the check engine light comes on. It does not correctly deplete, instead leaving me with no gas when it shows it still has gas available. This has left me stranded in various locations as my car runs out of gas, but doesn't show me that until it is completely empty. Most recently, it was on a very busy road in the middle of traffic. The gas gauge went from 1/2 full to empty while I was driving. Upon taking it to the dealer, they said to replace the 1 sensor, which is a very small, simple piece, they have to replace the entire fuel system, which is over $5000 in repairs. My car is only 4 years old and only out of warranty by 6 months. Further research shows this is a common issue with the make and model of my car. Many seem to happen under warranty, but with the age my car is now, many of these warranties will expire, leaving owners to have to pay to fix this outrageous, costly repair.

The contact owns a 2021 Volkswagen Tiguan. The contact stated that while driving at an undisclosed speed, the contact's dad who was following behind the vehicle noticed oil splashing onto the front windshield of his vehicle. The contact's dad then noticed while the contact was driving uphill, oil was splashing out of the oil pan. In addition, the contact's dad noticed smoke coming out of the exhaust. The check engine and PCV warning lights were illuminated. The vehicle was driven to the shoulder of the road. The vehicle was inspected, and the contact's dad noticed that the oil pan was completely empty. The vehicle was towed to an independent mechanic, where it was diagnosed with a cracked oil pan. The contact was informed that the oil pan, gasket, and filter needed to be replaced. The vehicle was repaired; however, the failure reoccurred. The contact stated that while driving at an undisclosed speed, the contact's dad noticed the oil splashing underneath the vehicle again. The vehicle was driven to the shoulder of the road. The vehicle was inspected, and the contact noticed that oil was spilling out onto the road. The oil pan was empty. The vehicle was towed back to the independent mechanic. The independent mechanic contacted the dealer. The independent mechanic was informed that this was a known failure with the vehicle. The independent mechanic was informed that the failure was that the PCV valve had either failed or was clogged. The independent mechanic was informed that the failure normally occurred between 60,000-100,000 miles. The contact was informed that the failure might recur after the repair, however there was no recall for the failure. The vehicle was being repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 93,000.

The 2021 Tiguan, R-Line that I own now requires a new engine after roughly 70,000. The engine is no longer under warranty, According to the VW Dealership, this is what is wrong with the engine - Based on our observations and diagnostic review, we have determined that damage to the rotating assembly was caused by the presence of one or more metal objects entering the engine. This type of foreign-object intrusion can lead to significant internal impact, which is consistent with the damage we found during our assessment. Also, if you do a search on Reddit and other public forums, there are a lot of 2021 VW Tiguan's with similar issues.

I’ve had my Volkswagen Tiguen since 2021 fresh off the lot. I have been the only owner of the car at about 30,000 miles my head gasket blew, causing the engine to go into default after weeks in the dealer. They replaced the head gasket and stitched it up, the head gasket blew again at this point I was still under warranty so they agreed to replace the engine. It drove fine after the engine was replaced this year 2025. I started to have a whole host of problems. It began to jerk and hesitate at acceleration. My engine light came on with continuous jerking upon acceleration for weeks until I started to lose power in my engine. I couldn’t go over 50 60 mph. I would always pull the car over power it off and power it back on just to see if it would change and it didn’t do much I had a local mechanic add oil to each tire also drain the engine, which had shards of metal in it. And basically stitch the car back together until we can figure out the bigger issues. It’s only been a day since the oil was added to each tire. I had a very violent jerk of the engine, which made it feel and sound like I blew a tire I got out to look at the tire and it was just fine. It was the backfire of the engine going into the exhaust that caused such the violent jerk. Happy that no one was on the road. If somebody was behind me it would’ve easily been an accident. Most of these dealerships know exactly what’s going on and have been avoiding the big conversation of what to do next they rather just replace and Band-Aid these things into the consumer just gives up. I have two small children and this is the only means of transportation. I’m fearful that I’ll be stuck with a car note for a car. I can’t drive.

Mechanical trunk lid emergency release will not release from the rear of the vehicle. The locking mechanism failed and lid will not open.

I am experiencing severe oil consumption and leakage with my 2021 Volkswagen Tiguan. The low oil level light began coming on weekly, and I have had to add oil nearly every week to keep the engine from running dry. Recently, I noticed oil leaking underneath the vehicle and immediately parked it. After parking, the vehicle began leaking oil excessively. The problem appears related to PCV system failure, which has caused multiple oil seals to rupture. After researching online, I found many other Tiguan owners reporting the same issues — including PCV valve failure, cracked oil pans, damaged valve seals, and crankshaft seal failures. My vehicle is no longer under the manufacturer’s warranty, and the dealership has not provided a fix. This defect presents a major safety concern because the engine can suddenly lose oil pressure or seize while driving, leading to sudden loss of power or control, which could cause an accident and potential injury. It appears Volkswagen has been aware of similar issues in other model years, but has not issued a recall or permanent repair for this problem. There is currently a class action lawsuit for the exact same issue for 2022 - 2023 Volkswagen Tiguan but doesn't currently include the 2021 Tiguan that I have. I am requesting that NHTSA investigate these widespread PCV and oil consumption failures in 2021 Volkswagen Tiguan vehicles.

Check engine light came on with excessive oil leaking from engine. Dealer inspected and diagnosed the PCV/Oil separator had failed, multiple valve stem seals had failed, and valve stem guides were worn causing excessive crankcase pressure. Dealer recommended cylinder head replacement. Vehicle has been at the dealer a month with the cylinder head on backorder and no timeline for resolution. Dealer indicated thousands of cylinder heads in the queue, with tens of units being distributed per month.

2021 Volkswagen Tiguan, Approximately 40,000 miles
Date of failure: Oct 12th, 2025
Component(s): Engine, Powertrain, Vehicle Speed Control, Throttle body Description of the problem:
My 2021 Volkswagen Tiguan experienced a complete engine failure despite having multiple prior service visits for engine-related issues while it was still under warranty. During the warranty period, I brought the vehicle to Grand Junction Volkswagen (Grand Junction, CO) several times for problems including: * Excessive oil consumption * “Check coolant” warning light turning on * EPC (Engine Power Control) mode activating and loss of power The dealership performed an oil consumption test and told me the results were “normal,” but they did not address the coolant light or EPC issues, stating these conditions were within normal limits. The same problems continued after each visit. At approximately 40,000 miles, the engine failed completely while driving, leaving the vehicle inoperable and creating a significant safety risk. The vehicle had to be towed. Volkswagen is now denying liability, claiming the vehicle is out of warranty, even though the same engine problems were documented repeatedly while it was still under warranty. I have opened a case with Volkswagen of America Customer Care (Case #07085098), but there has been no resolution so far. Safety concern:
This issue poses a serious safety hazard. The vehicle can lose power suddenly and stall while in motion, which could lead to a crash or leave occupants stranded in unsafe conditions.

The overhead console has come disconnected inside of the vehicle. I am seeing countless comments and posts online, both on Volkswagen site as well as other automotive sites, that also report this same issue for Tiguan autos from the 2020 through 2022 years. My car is a 2021 VW Tiguan. I am calling the Perrysburg Auto Mall VW Dealership located in Perrysburg, OH to request full service and that this should be covered under the extended warranty that I have seen is a part of this automobile. I wanted to make sure I reported this incident to this governing board.

The check oil light indicated that the oil level had become too low. The Volswagen dealership service technician identiifed the cause to be from the exhaust valve seals wearing out. The cylinder head needs to be replaced per their recommendation. No warning apart from the low oil indicator.

I purchased about 4 months ago with about 139,000 miles on it. The vehicle now has 142,000 miles and is experiencing excessive oil consumption—approximately 0.9 quarts per 600 miles. VW seems to be pushing this off and as I try to use my extended warranty I purchased when I got the car, AUL has asked for an engine tear down. VW knows about this issue, as it is internally a known issue for this model, yet they are unwilling to help. At time of purchase, this issue was not disclosed to me, as such had it been, I would not have chosen this car.

Check Engine Light came on and got estimate from Pete Moore VW Dealer in Pensacola, Florida and was told the car needed extensive engine repair which included a new cylinder head part. So we waited to come get the car repaired on 3/5/2026 once we had saved up the money for it. We found out the cylinder head is on a Nationwide back order with NO estimated time to get it fixed properly. The technician who gave us the estimate back in September 2025 failed to mention that the cylinder head has been on a Nationwide back order during that time. I am not the only person dealing with this issue in the USA but feel VW has not provided a fix or estimate time to repair these cars properly causing a safety hazard. This time to wait for a part is unacceptable and feel our cars fall under the Lemon Law.

Upon starting my 2021 Volkswagen Tiguan, the vehicle immediately went into "limp" mode and the check engine light and EPC light came on. The vehicle would not drive over 18 mph. The car was towed to a close by Volkswagen dealership and checked for codes using a multipoint inspection. The report came back with a throttle body issue (Multipoint inspection report attached). The throttle body was replaced and the vehicle was taken for a 15 mile test drive. During the drive, the same problem occurred. After the drive, 34 codes were found in VWs report. I have also attached the report to this complaint. The technicians at the VW dealership didn't understand the problem, so they opened up communication with Volkswagen in Germany. The Volkswagen engineer advised the dealership to replace the wire harness. After the wire harness was replaced, the car has no more issue (although it has only been 5 days since), which cost $2314.54 in total. There is a class action lawsuit in the state of New Jersey (Case [XXX]) against Volkswagen Group of America that states "VW is aware of concerns involving faulty wire harnesses"... affecting 2019-2022 Volkswagen Atlas, Golf, Jetta, TIGUAN, and Taos. Thank God that this happened to my vehicle with the car was at rest and not traveling at a high rate of speed that could have been fatal.
