2018 Volkswagen Tiguan problems

FUEL/PROPULSION SYSTEM

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.

ENGINE

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.

FUEL/PROPULSION SYSTEM

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.

SUSPENSION

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.

ELECTRICAL SYSTEM

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.

Other/I am not sure

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.

Our 2018 Volkswagen had a light that came on so we took to dealership. The part that needs replaced is the cylinder head assembly which will be over $6000 plus $3k for timing. It will take over 28 weeks to get the part. So the car is not able to be driven. After looking into this, this is a known issue and there is a class action lawsuits going on right now. There are 4,600 back order parts nationwide. This is a defective part that the company has not recalled. The dealership is aware also that this is a known issue. There was not an injury but they say it is unsafe to drive. Volkswagen has no resolution for problem for a known defect part.

UNKNOWN OR OTHER

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!

First purchased this car from a dealership in 2023, used at128,051 miles. Did not have any problems with it in the first year I would say. Then suddenly while driving down the road the epc light would come on limiting my speed to 4,000 rpm. It would come on and off also causing my check engine light to come on and off. It has now become more frequent, the epc and check engine lights will come on and off creating a major hazard while driving. Got it scanned while the check engine light was on and it ran a code for a cylinder 4 engine misfire from my fuel injector wiring rail harness. It looks to be a common problem with this model but it’s showing my vin is not attached to a recall.

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.

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.

AIR BAGS

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.
