2018 Volkswagen Tiguan Complaints

UNKNOWN OR OTHER,LANE DEPARTURE,BACK OVER PREVENTION — Filed 04/25/2026

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!

ENGINE,FUEL/PROPULSION SYSTEM — Filed 04/25/2025

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.

SUSPENSION — Filed 03/11/2026

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.

ELECTRICAL SYSTEM,AIR BAGS — Filed 12/10/2025

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.

ELECTRICAL SYSTEM,AIR BAGS,STRUCTURE — Filed 03/20/2026

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.

POWER TRAIN — Filed 02/01/2026

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.

This vehicle experienced a rear shock spring failure identical to the symptoms noted in VW recall 42i7. We paid out of pocket for the springs to be repaired, and VW corporate along with the dealer reported this VIN does not qualify for the recall. They are unable to tell me why our particular VIN does not, other than it simply wasn't on the list. It seems unlikely the exact year/model/failure occurred on our vehicle as what was stated in the recall but somehow it didn't qualify I would expect VW to cover the spring replacement and required alignment

ENGINE — Filed 09/05/2025

I own a 2018 Volkswagen Tiguan with approximately 70,000 miles. The vehicle requires a full cylinder head replacement due to faulty valve seals. I have been having to add engine oil frequently between oil changes. The repair has been confirmed by an authorized Volkswagen dealership. The required cylinder head part is currently on manufacturer backorder with no estimated time of arrival. Dealership told me to check in every 2-3 months, as no additional cylinder heads can be ordered due to excessive backorder. Dealership charges $6,000+ for this repair. Volkswagen has not provided a solution or timeline for repair with this ongoing issue. There were no warning lights prior to the issue, and the vehicle has been routinely maintained. A major engine component failure at this mileage raises concerns about a potential defect rather than normal wear. This situation creates a safety and reliability concern, with no reasonable repair timeframe due to parts unavailability as well as no communication from Volkswagen regarding this ongoing issue.
