2018 Volkswagen Tiguan Problems

We have to add 1-2 quarts of oil every 600 miles. Our check engine light came on 02/2026 for carbon buildup. We had it cleaned, had timing chain replaced, piston rings, oil valves, manifold. Cost us $5300. The car ran fine before the light came on and all of a sudden it started making grinding noises and idling rough. We change the oil every 3,000 miles and the car burns through oil constantly. Our car stalled 4 times on the highway since then almost causing wrecks, it runs rough and now our check engine light is back on for the same issue. It’s causing emotional and financial distress. There are multiple lawsuits pending for this but something needs done. This is exhausting.

This vehicle goes through oil at a rapid rate. I am adding oil to my car every week. I have had to add at least 2 quarts between oil changes for the duration of owning the vehicle.

The contact's daughter owns a 2018 Volkswagen Tiguan. The contact stated that while her daughter was driving at an undisclosed speed, the vehicle shook and decelerated abnormally. The vehicle was taken to the dealer, who determined that the vehicle should not be driven because the drive belt needed to be replaced; however, the part was on backorder with no ETA. The vehicle was not repaired. The manufacturer was made aware of the failure but provided no assistance. The failure mileage was approximately 60,000.

On multiple occasions, while driving on the highway, subject vehicle displayed check engine light and EPC light at random intervals and an alarm saying exceeded 4000 came on. RPM's were not over 4000. Speed and acceleration severely limited making it dangerous to pull over on the highway in traffic. Had to pull car over and restart engine. This has happened numerous times. Also experienced shaking and skipping or missing of transmission. The car has also had the engine stall or stop when at red light or stopped forcing restart of engine.

I purchased this 2018 Volkswagen Tiguan in September 2019 and began noticing an intermittent rearview-camera problem around that time. I do not remember the exact date of the first occurrence because the problem initially happened only occasionally and was not persistent. When the vehicle is placed in reverse, the rearview camera intermittently fails to provide a reliable image. At other times, it operates normally. Because the problem is intermittent, it has been difficult for the dealership to reproduce consistently. Loss of the camera image reduces visibility behind the vehicle and creates a safety concern while backing up. An authorized Volkswagen dealership inspected the vehicle. The service manager stated that the stored fault indicates an intermittent open circuit in the video cable. The dealer’s diagnostic history reportedly shows approximately 90 fault occurrences beginning July 19, 2026. During recent testing, the dealership was able to get the fault to set once. The dealership has not conclusively confirmed that the camera control module failed. It proposes replacing the module as the first repair step for approximately $1,165 and stated that additional repairs may be necessary if the module replacement does not correct the problem. Volkswagen Customer CARE documented the concern under Case Number 07696586. I am submitting this report because the intermittent loss of the rearview-camera image may reduce the driver’s view behind the vehicle and increase the risk of a backing collision.

2018 VW Tiguan. The fuel injector harness failed. There is a NHTSA letter stating 2018-2019 Tiguans had this issue and there’s an extended warranty up to 120,000 miles. My Tiguan is at 91,000 miles, but VW is saying the warranty isn’t assigned to my VIN. So there’s a warranty for this exact issue and year, but my vehicle isn’t covered. This warranty obviously needs to be extended by build date as it’s a pretty costly repair.

A few weeks ago i noticed that a car passed me and the little blind spot alert light didn't light up. when i arrived at my destination I did some scanning through the menus and i discovered that the blind spot (side assist) was not on, but when i attempted to turn it on, the car said "function not available". After some investigation (using a odbeleven scanner) i discovered that the blind spot assist functionality has a fault with "no communication". This system, upon failure, give NO indication anywhere, plus this also means my rear back up alert ( a kid running behind my car, for example, which would normally cause a huge alert, nothing happens). I also learned that there is a technical bulletin : [XXX] related to this. This should be a recall, its dangerous to have no indication that a safety feature system like this is completely nonfunctional (without an ODBeleven read). a light on the dash should alert me, or a message on the screen. this is just plain dangerous!

The car went into limp mode on an Interstate Highway. It was taken to a VW dealer in Mooresville, NC after two other private garages could not diagnose the problem. Their is a current Factory Warranty Extension for 2017, 2018, 2019 VW Tiguan's. The dealer in Mooresville kept the car for two weeks. Drove it for over 100 miles. They claim They can see the code in the computer but it is not active so VW will not pay for the known problem. I feel this is a safety issue as the car will not only possibly go into limp mode at any time but when stepping on the accelerator when not in limp mode the exhibits another known fault. The engine initially sputters as if it is going to stall then accelerates very quickly.

I began intermittently noticing a gasoline/fuel odor shortly after taking possession of the vehicle in June 2026. The odor became significantly worse, and I formally reported it to the selling dealership on July 9, 2026. The vehicle was subsequently taken to an authorized Volkswagen dealership for evaluation. A repair order dated July 23, 2026 documents: “Customer states that the vehicle smells of fuel. Could not duplicate customer concern.” Before the evaluation, I explained that the odor becomes most noticeable after the vehicle has been driven for an extended period, particularly in extreme Arizona heat. My normal commute is approximately one hour each way and 60 miles per day. I do not know how far or under what conditions the vehicle was road-tested during the evaluation. The vehicle remained with the dealership during the repair process and was returned to me on August 13, 2026. The condition has continued and has become substantially worse. After extended driving in extreme heat, the gasoline odor can become unbearable and is now noticeable inside the passenger compartment while I am driving. When parked in my home garage, the gasoline odor becomes strong enough to enter the house, and neighbors have also noticed it. The odor has also resulted in complaints from others in the parking garage at my workplace. I’m currently using approximately one tank of gasoline every two and a half days. I do not know whether the fuel consumption and gasoline odor are related. The specific failed component is UNKNOWN. The vehicle remains available for inspection. The concern has previously been presented to both the selling dealership and an authorized Volkswagen dealership, but the cause has not been identified and the condition continues.

My 2018 Volkswagen Tiguan experienced a failure of the airbag control module caused by water intrusion through the HVAC access area and failed seam seal tape at the cowl support. The dealership confirmed that water leaked through a factory seam, accumulated at the airbag module, and caused the module to fail. The airbag warning light is illuminated, and the system is inoperable. This failure matches the same defect pattern covered under Volkswagen’s recall campaigns for the Atlas and Atlas Cross Sport (water intrusion leading to airbag control module failure), but my VIN is not included. The root cause and safety implications are identical: water entering through a body seam/HVAC area and compromising the airbag system. This is a safety‑critical issue that disables the airbags and creates a risk of injury in a crash. I am requesting NHTSA review this defect for potential recall expansion. Dealership Findings: • Water present at airbag control module • Water leaking through HVAC access hole • Failed seam seal tape at cowl support • Water accumulation damaging the airbag module • Cowl trim cracked and repaired • Recommended replacement of airbag control module and seam sealing tape • Estimated repair cost: $1,377 + tax Safety Concern: Airbag system is disabled due to water intrusion from a factory seam. This creates a risk of injury or death in the event of a collision.

1)My sunroof/window is leaking. This has caused internal damage. My car had 2-2.5 inches of water that has damaged by carpeting and pads the 60E5 was performed. ~72,500 miles 2018 Tiguan. 2) dealer service has advised of service:REPLACE SET OF (4) FUEL INJECTOR O-RINGS DUE TO FUEL LEAK AT FUEL RAIL-INCLUDE INTAKE MANIFOLD GAKET AND THROTTLE BODY GASKET.

The 2018 Volkswagen Tiguan SE (4Motion) has approximately 75,000 miles on it. The rear driver-side brake lines failed, snapping in half, which resulted in a complete loss of brake fluid. Consequently, the vehicle was unable to stop unless the emergency brake was engaged.

The panoramic sunroof continually leaks into the rear c-pillar. Each time it rains the seat belts become saturated with rain water. I am of the opinion this will cause more rapid deterioration of the seat belts than usual. Additionally, water ponds in the rear floor boards and is a mold hazard. The last rain, the rear seat also became saturated and our baby's carseat got wet. VW claims there is no defect in the sunroof.

Seatbelt is not functioning adequately. The seatbelt itself that’s contained in the column near the door is not retracting or staying taught when in use. It’s very loose and something inside is rattling when ejected, and it has to be manually assisted to retract.

Low beam on Both headlights failed without any explanation. Everything was checked. The bulbs, the fuses, the relay, and the cause of the issue is still not known.

The light of the roof inside. Mainly problem of a lot of cars !

The contact owns a 2018 Volkswagen Tiguan. The contact stated that while driving at an undisclosed speed, the parking brake independently activated, and the air bag warning light illuminated. In addition, while attempting to turn off the vehicle, the key failed to function as intended. The vehicle was driven to the shoulder of the road and turned off. The contact stated that while attempting to start the vehicle, several unknown warning lights were illuminated. The parking brake was not activated. Additionally, the front driver's side door latch failed to unlatch as needed. The contact stated that none of the electrical system features functioned as intended. The vehicle was taken to the dealer, where it was diagnosed with a failed wiring harness and a failed front driver's side door harness. The contact was informed that the wiring harness and front driver's side door harness needed to be replaced. The vehicle was not repaired. The dealer reset the codes. The contact was informed that until the repair was performed, the failure would recur. The contact referenced an unknown recall with a similar failure; however, the VIN was not associated. The manufacturer was not made aware of the failure. The failure mileage was unknown.

- Power steering pump PN#5QN-423-055-A, not sure if dealer kept. - Risk to both as lost all power steering in winter weather. - Yes, confirmed defective by dealer - I do not know if they did additional inspection or send to Manufacturer. - On [XXX] a yellow power steering light illuminated while driving and steering became more difficult. I took vehicle home and reached out to Volkswagen and then to local service center where I purchased. I was given a date of 2 weeks out at the Countryside, IL location and then was told the Orland Park, IL location could accept my vehicle on [XXX] which when I started the vehicle and the yellow light was now red and had completely lost power steering. I had vehicle dropped off in early AM. I was told they cannot provide a loaner because they are all out because they have so many vehicles in for repair. I did not get any response about situation for over a week and after few calls a week and half later I was told the rack and pinion needs to be replaced & the part is backordered & not expected until March 7, 2014. Could not guarantee because were unaware of quantity & how many need to be fixed before as 1st come 1st served. The service advisor told me they have been experiencing many issues with power steering, engine, turbo, timing chain errors, and a # more of issues throughout their lineup. I asked a percentage and he stated 30-40%, this shocked me completely. He calmly said that they produce so many vehicles that this is a low #? I reached out to Countryside, IL told them that I need a vehicle it the interim after negotiation they finally agreed to transfer vehicle to their location and provide a loaner. I was required to to get vehicle there myself on [XXX] I was not able to start vehicle because battery was dead, after jump still red light no power steering. Was told that typically they don't do transfers and would have to diagnose again. I received car back on [XXX] have less than 10 miles seems ok4now INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFOR

My 2018 Tiguan won’t turn on. The dash says, “Steering Lock Fault. Stop!” I towed it to the dealership and they replaced the steering column. Four days later it happened again while I was in the middle of the city at night and couldn’t go anywhere. This is a safety hazard because it could mean even after a repair, it can continue to lock up and not turn on out of no where. Both times there was never any warning given anywhere by the vehicle that this could happen. Just out of the blue it decides not to turn on and gives me that message.

While I was driving down a flat road this past week, the front left coil spring on my 2018 VW Tiguan S spontaneously broke, causing a large chunk of the coil spring to bounce around in the wheel well of the car and ultimately flying out into oncoming traffic as well as the left front end of my car to dip forward due to the shortening of the leftover coil spring. After going to the repair shop, I learned that this is a very common issue among VW products of these years. I also came to find out that my front control arms bearings are in need of replacement due to loose bushings, which is an already recalled issue on certain 2018 VW Tiguan vehicles, but of course, my vehicle is not listed under the recall. I am extremely upset and disappointed that my vehicle is being affected by all of these known recalled issues, yet when I run my VIN number, my car is never "affected". Suspension issues can be extremely dangerous, and I feel as if the issues that I have been having are known issues; I should have the right to get them repaired under recall rather than having to pay out of pocket once the part ultimately fails, putting me and others at risk for injury.

Front coil spring fractured at 84,554 miles. I am the original owner with full dealer-maintained service history. VW issued Safety Recall 42J5 for premature rear coil spring fracture on 2018–2019 Tiguans due to material specification and manufacturing process defects at the spring supplier. The front springs on this vehicle came from the same supply chain and production window. VW dealer in [XXX] noted that spring failures are common in this area on these vehicles. VW Customer CARE declined goodwill assistance. Requesting investigation into expanding Recall 42J5 to include front axle coil springs.

I discovered a potential safety defect while inspecting and preparing my Graco Turn2Me child restraint for eventual forward-facing use. The seat is Model 2170122, manufactured 08/26/2024. The physical SnugLock/LATCH configuration of my seat appears inconsistent with Graco’s published Turn2Me instructions and installation videos. The rear-facing SnugLock lock-off/release mechanism shown by Graco does not appear to be present or accessible on my seat. The gray InRight lower-anchor/LATCH strap is routed through the blue rear-facing belt path and cannot be repositioned in the manner shown in Graco’s instructions. I cannot move the lower-anchor system into its designated storage location or reroute it through the orange forward-facing belt path as required for forward-facing LATCH installation. This child restraint has been used to transport my child before I discovered the condition. There was no crash, fire, injury, or fatality associated with the discovery. I have stopped using the seat. I reported the issue directly to Graco. Graco created Case #52041838 and Case #52041872, cross-referenced them for Product Safety review, and instructed me in writing to “refrain from using the product until further advice is given.” I am requesting that NHTSA review this as a potential manufacturing/assembly or child-restraint safety defect. Photographs documenting the seat, lower-anchor routing, apparent SnugLock discrepancy, and manufacturer label are available.

I originally started out at World Kia in Matteson, where I was approved for a newer vehicle. But then they suddenly changed their minds and tried to put me in an older car instead. That rubbed me the wrong way, so I went to their Joliet location hoping for better service. Boy, was I wrong. Even though they had already run my credit in Matteson, they reran it again in Joliet, which made no sense and damaged my credit even more. I really needed a car at the time, so I felt pressured and couldn’t walk away. After I bought the car, it broke down shortly after, and I was never given any paperwork about its condition or inspection. They sold it to me “as-is,” but I later found out that under Illinois law, used cars must be safe and reliable for at least 15 days or 500 miles, even when sold “as-is.” My car didn’t meet that standard at all. The car has suspension issues which is very dangerous. The mechanic stated to not drive the car at all it's a safety hazard and I could cause a major accident. There is no recall on my vin#, but several other owners have had the same issues based of the information on the website. I just want some kind of resolution. I'm still responsible for the car, which is so unfair. This has caused so much stress that I have no clue what to do. please help.
