Even though the VW Tiguan is a mid-tier premium vehicle, it still has some problems to be aware of before buying.
The Volkswagen Tiguan suffers from intake manifold failure, timing chain tensioner failure, steering clock spring failure, water pump failure, PCV valve defects, ignition coil failure, and excessive oil consumption.
To help you make a more informed decision, we’ve broken down these issues below and looked at some Tiguan recalls you need to be aware of (especially if you have one of these models).

7 Common Volkswagen Tiguan Problems
1. Intake Manifold Failure
This isn’t a problem you hear of often with other manufacturers, but since the Tiguan has a plastic intake manifold, it can be a problem.
The affected engine is the 2009 2.0TFSI 4-cylinder, around 55,000 miles (88,514 kilometers).
The intake manifold distributes the air equally between the cylinders, and if it gets a crack, it results in a vacuum leak.
This will affect the car’s performance because it is turbocharged, it will lose boost pressure to the cylinder under load, and at idle, it will be rough since there is unmeasured air coming into the engine because it is behind the Air-flow meter and throttle body.
The only solution for this problem is replacing the intake manifold, which can cost up to $760.
2. Timing Chain Tensioner Failure
The job of the timing chain is to keep the engines crank and camshafts in time with one another, and the tensioner is there to take up the slack in the chain.
The engine affected is again the 2.0 TFSI 4-cylinder from 2009 to 2013 at around 90,000 miles (144,841 kilometers).
Catastrophic engine failure can occur if the tensioner fails since it can make the timing chain skip a tooth on the crank or on the camshafts resulting in the valves hitting the piston.
Luckily you can hear the tensioner starting to fail because it will emit a rattling and ticking sound at startup when the oil pressure builds up.
If you can catch the problem in the early stages, you only need to replace the tensioner and timing chain, which will cost about $2,600.
If you are not lucky, you will need to replace your engine, which can cost up to $6,500, or you can rebuild it.
3. Water Pump Failure
The first generation of external plastic water pumps on the Volkswagen Tiguan had an issue where it would crack and start leaking coolant.
This can result in the car overheating and causing engine damage, like a head gasket.
This was a problem on all vehicles in 2009 fitted with the electric water pump at around 78,000 miles (125,529 kilometers).
In most cases, the owners reacted to the water temperature warning light, pulled over as quickly as possible, and only had to replace the pump, which cost up to $910.
Some owners were so unlucky in the first year of replacements and got the nonupdated part, so it failed again in a very short time. The worst I’ve seen is this one owner who replaced three water pumps in an 18,641 miles (30,000 km) range.
4. PCV Valve Not Functioning
The PCV valve controls the crankcase pressure by letting it breathe into the engine’s intake so the engine can burn the oil vapors.
With the Tiguan, the PCV valve isn’t letting enough air through to properly vent the crankcase pressure, pushing out the rear main oil seal.
This was at its worst in the 2010 model year 2.0 TFSI 4-cylinder models at around 81,800 miles (131,644 kilometers).
The problem with losing the rear main seal is the loss of engine oil which can result in engine damage and turbo damage since it also uses the engine oil to lubricate its bearings.
The updated PCV valve and rear main seal will set you back around $1,700.
5. Ignition Coil Failure
The ignition coils give spark to the sparkplugs to ensure the engine efficiently burns the fuel.
The 2012 model year of the petrol-engined Tiguans had ignition coil packs that failed prematurely at around 54,000 miles (86,905 kilometers).
Bad coils can result in misfires, bad acceleration, and poor fuel economy.
The only fix is replacing the coils, which costs up to $570 for four coils.
6. Steering Clock Spring Defect
The steering clock spring’s job is to connect everything electronically on the steering to the vehicle’s ECU and airbag control module.
When they turned hard to the left or right, many owners heard a snapping sound from the steering column followed by the airbag warning light illuminating.
This is common in 2012 and 2013 model Tiguans at around 39,300 miles (63,247 kilometers).
Over time, the clock spring will bind on the inside and break randomly.
The biggest problem with the clock spring breaking is that the airbag won’t deploy in an accident.
7. Excessive Oil Consumption
This is quite a normal problem in modern vehicles, and even the Volkswagen Tiguan is not spared from it.
This problem was worst in the 2018 Tiguan 2.0TFSI 4-cylinder at around 18,150 miles (29,210 kilometers).
Some owners complained of oil consumption of 1.6 quarts (1.5 liters) in approximately 1,243 miles (2,000 kilometers).
Volkswagen says normal oil consumption is a quart (0.95 liters) every 621.4 miles (1 000 kilometers), which is a lot compared to older vehicles that could get by on 100ml between services.
Volkswagen Tiguan Recalls
While many Volkswagen Tiguans have been recalled, many out there were still not repaired, so consider these problems when buying a second-hand Tiguan.
If you own a Tiguan, take your vehicle to a dedicated Volkswagen dealer to rectify these problems as soon as possible.
- 2009 model-year vehicles equipped with the 2.0TFSI have an engine control module (ECM) with software that may not properly control the engine idle when the air conditioning is turned on, resulting in an unexpected increase in rpm.
