The 2014 Volkswagen Tiguan, while a popular compact SUV, has been reported by owners to experience a range of issues, particularly concerning its engine and electrical systems. Understanding these common 2014 Volkswagen Tiguan Problems is crucial for prospective buyers and current owners alike to ensure vehicle longevity and address potential repairs proactively. From engine malfunctions to electrical glitches, this article delves into the typical problems associated with the 2014 Tiguan model.
Engine and Powertrain Troubles in the 2014 Tiguan
Engine problems are a significant area of concern for the 2014 Volkswagen Tiguan. Owners have frequently reported issues affecting various engine components, leading to performance degradation and potential breakdowns. Let’s explore some of the most prevalent engine-related problems.
Throttle Body Malfunctions
Throttle body issues are a recurring theme in 2014 Volkswagen Tiguans. Symptoms often include rough idling, noticeable fluctuations in RPM, and the illumination of the check engine light. A faulty throttle body can disrupt the engine’s air intake, leading to diminished performance, especially at lower speeds and during city driving. This issue can affect both earlier and later production models of the 2014 Tiguan.
Turbocharger Failures
Turbocharger problems are another significant concern for 2014 Volkswagen Tiguan owners. Reports of turbocharger malfunction or complete failure are common, with drivers experiencing a drastic loss of power and difficulty maintaining speed, particularly at highway speeds. An engine that sounds like it’s working harder than usual can be an indicator of a failing turbocharger. The frequency of these turbocharger issues has even led to petitions from Volkswagen owners for a potential recall to address the problem.
Carbon Deposit Buildup
A known engine design characteristic in Volkswagen Tiguans, including the 2014 model, is the tendency for carbon deposits to accumulate. This buildup is particularly pronounced in the TSI direct injection engines used in the Tiguan. Carbon deposits can manifest as black smoke from the exhaust, sensor failures, and a general decline in engine performance. Specifically, owners may notice power loss, irregular idling, difficulty starting the engine, reduced acceleration, and engine misfires. Resolving carbon buildup requires a thorough cleaning of the intake manifold, cylinder head intake ports, and intake valves.
Timing Chain Tensioner Issues
Timing system problems represent one of the more serious and costly issues that can affect a 2014 Volkswagen Tiguan. The plastic timing chain tensioner is known to be prone to failure. Rattling noises or engine misfires, especially during idling, can signal a failing timing system. Additionally, a check engine light combined with engine oil contamination could also indicate a timing chain issue. Addressing timing chain problems promptly is crucial to prevent more extensive engine damage.
Acceleration Hesitation
Hesitation during acceleration is a particularly concerning problem reported by 2014 Tiguan owners. This issue is described as severe and unpredictable, potentially creating dangerous driving situations, especially when merging onto highways. Frustratingly, this acceleration hesitation often does not trigger any diagnostic trouble codes, making it harder to pinpoint the exact cause. However, it is frequently linked to a lean fuel/air mixture, which could stem from a malfunctioning mass airflow sensor, a failing fuel pump, a defective throttle position sensor, or clogged or failing fuel injectors.
Electrical System Issues in the 2014 Tiguan
Beyond engine problems, electrical system malfunctions are another common complaint among 2014 Volkswagen Tiguan owners. These issues span various electrical components, impacting both convenience and safety features.
Exterior Lighting Problems
Problems with exterior lights are frequently reported in the 2014 Tiguan. These include failures of both low and high beam headlights, issues with the ambient lighting bar in the sunroof, and taillight malfunctions. The prevalence of some of these lighting issues led Volkswagen to issue recalls to rectify them, highlighting the significance of these electrical faults.
Infotainment System Glitches
While infotainment system issues are more commonly associated with newer Tiguan models, the 2014 version is not immune. Freezing or complete blackouts of the infotainment screen have been reported. While sometimes these issues can be resolved with system resets or software updates, it’s worth noting that Volkswagen issued a recall in 2018 for Tiguans due to instrument cluster failures that could fail to warn drivers if the key was left in the ignition.
Other Notable 2014 Tiguan Problems
Beyond engine and electrical systems, 2014 Volkswagen Tiguan owners have reported a range of other issues, affecting various aspects of the vehicle.
Excessive Oil Consumption
Excessive oil consumption is another problem experienced by 2014 Tiguan owners. Engines requiring frequent oil top-ups are a common complaint, with some owners expressing concern over the alarming rate of oil depletion. While some dealerships have reportedly considered a quart of oil consumption every 1,000 miles as “acceptable,” many owners find this level of oil burning unacceptable. This issue is often linked to problems with cylinder seals.
Rearview Camera Malfunctions
Rearview camera issues are a fairly common problem in many contemporary Volkswagen models, and the 2014 Tiguan is no exception. The frequency of these issues has prompted Volkswagen to issue multiple recalls aimed at resolving rearview camera malfunctions.
Airbag System Concerns
Airbag-related problems are also relatively frequent in modern Volkswagen vehicles, and the 2014 Tiguan is no different. Complaints range from issues with the airbag control module to problems with frontal airbag deployment, side/window airbags, and coil spring issues. These airbag concerns represent a significant safety consideration for 2014 Tiguan owners.
Automatic Emergency Braking Problems
Automatic emergency braking (AEB) system malfunctions have been reported by 2014 Tiguan owners. These problems manifest as either the emergency brakes engaging unexpectedly without driver input, or conversely, failing to activate in situations where they should. While reported more frequently in 2018 and newer models, 2014 Tiguans can also experience these AEB issues, potentially caused by overly sensitive sensors.
Steering System Issues
Two primary steering issues have affected the Tiguan since its introduction, including the 2014 model year. The first involves the clock spring, which can break, leading to multifunction steering wheel failures and impacting systems like the airbag. The second common steering problem is the sudden disengagement of power steering assist, causing the steering wheel to become very heavy and difficult to turn.
Fuel System Problems
Both diesel and gasoline-powered 2014 Tiguan models can experience fuel system-related issues. These include fuel leaks, a faulty fuel pump, and problems with the N80 purge valve. Fuel leaks can arise from faulty fuel lines, while a failing fuel pump can lead to poor engine performance, increased fuel consumption, fuel leaks, and engine stalling. Notably, Volkswagen issued a recall in July 2014 due to fuel pumps failing to maintain correct fuel pressure.
N80 Purge Valve Issues
The N80 purge valve is another fuel system component that can cause problems in the 2014 Tiguan. Symptoms of an N80 purge valve failure include performance issues, reduced fuel economy, and a check engine light. A malfunctioning N80 valve can disrupt the fuel vapor recovery system, leading to either too much or too little fuel being delivered to the engine, impacting performance.
Engine Stalling
Engine stalling is a concerning issue reported by some 2014 Tiguan owners. This is often accompanied by the illumination of the Electronic Power Control (EPC) warning light. Engine stalling in the 2014 Tiguan has been attributed to a faulty fuel injector wiring harness or, in more severe cases, engine problems.
Seats and Seatbelt Wear
Finally, some 2014 Tiguan owners have reported issues with the vehicle’s seats and seatbelts. Premature tearing of seat upholstery and seatbelt malfunctions have been noted. While generally less severe than engine or electrical problems, these issues can still be frustrating for owners.
Conclusion: Addressing 2014 Volkswagen Tiguan Problems
In conclusion, while the Volkswagen Tiguan is a capable and popular SUV, the 2014 model year is associated with a number of potential problems, particularly concerning the engine, electrical system, and fuel system.
