Hyundai Tucson: overview of problems

The Hyundai Tucson is regarded as a popular compact SUV with a solid reputation, but this model also has its weak spots. From transmission issues to electrical faults, owners report various complaints that you should know about before buying or while owning one. Want to know whether the Tucson is a reliable choice and what you need to watch out for?

A solid model with a few caveats

The Hyundai Tucson has developed into a widely purchased compact SUV, both in the Netherlands and internationally. The model combines space, modern equipment and relatively sharp pricing. However, owner experiences and studies show that not all model years are equally reliable.

In the WhatCar? reliability survey the Tucson scored 94.3 percent, which is higher than brands such as Kia and Ford. Honda and Lexus scored even better. A recent Car Buyer Driver Power survey showed that 22.8 percent of owners experienced problems in the first year. That percentage is lower than for Mazda and Volvo, which puts the Tucson in a fairly favourable light.

However, there are specific model years and components that require extra attention. The 2011, 2012, 2015 and 2017 models are known as the least reliable versions. Owners of these model years report transmission faults, air conditioning problems and acceleration issues more often. By contrast, the 2008, 2009 and 2018 models have a better reputation in terms of performance and reliability. For Hyundai car problems, early detection and preventive maintenance often make the difference.

Transmission: juddering and hesitation in many models

Transmission problems are one of the most common complaints with the Hyundai Tucson. Models with the 7-speed dual-clutch transmission (DCT) in particular suffer from rough or delayed gear changes. This leads to a jerky driving experience that is annoying and uncomfortable.

The 2016 and 2017 models are especially prone to hesitation when pulling away from a standstill. Hyundai has released a software update for the transmission control unit (TCU), but several owners report that the problem persists even after this update. In severe cases the transmission fails completely. The car will then not move forwards. The gearbox also fails to shift correctly.

Hybrid and plug-in hybrid versions also suffer from jerky gear changes at low speeds. A defective flywheel is often the cause. Calibration issues with the transmission control unit are regularly at the root of the problem. This is not always easy to resolve.

What can you do if you have transmission complaints?

• Have the TCU software checked and, if necessary, updated at a Hyundai dealer
• Ask about known recalls for your specific year of manufacture
• If problems persist, consult an independent specialist for a second opinion
• Consider extending the warranty if you buy a used Tucson with DCT transmission

Engine problems: from knocking to complete failure

Older Tucson models, particularly the 2012–2014 versions, suffer from serious engine problems. Owners report engine knock, which may point to defective connecting rod bearings. This issue mainly occurs at higher mileages and sometimes leads to complete engine failure.

Intermittent starting problems and the engine cutting out unexpectedly are also reported. Some owners hear a loud knocking noise; the engine then stalls. These are warning signs that require immediate action. If you act quickly, further damage is often limited.

Newer models with turbocharged engines more often have problems with fuel injectors. This results in rough idling, misfires and the engine warning light repeatedly coming on. Fuel injector issues are often caused by contamination or wear and tear. They noticeably affect engine performance.

Prevention and early detection

• Listen for abnormal engine noises, especially knocking or ticking sounds
• Keep a close eye on the oil level and change the oil according to the prescribed schedule
• Have starting issues or engine warning lights checked immediately using diagnostic software
• Use quality fuel to minimise contamination of injectors

Infotainment and electronics: frustrations with modern systems

The newer generations of the Tucson are equipped with advanced infotainment systems, including the 10.25-inch touchscreen. This regularly leads to complaints. Owners report unresponsive touchscreens, completely frozen displays and connection problems.

Some users experience the screen going black and having to tap it several times before it responds. Full system restarts also occur, which can be distracting and unsafe while driving.

Apple CarPlay and Android Auto also cause headaches. Connections are frequently dropped, sometimes several times a week. Temporarily switching the vehicle off sometimes helps, but the underlying problem remains. Hyundai has released several software updates to tackle compatibility issues, but not all owners have been helped by these.

In addition to infotainment issues, there are reports of electrical faults under the driver’s seat that can affect the entire display and radio system. Battery problems and unexpected warning lights on the dashboard also occur, albeit less frequently.

Safety systems: false alarms and unreliable assistance

Tucson models built between October 2018 and October 2020 can experience a loss of brake assist. This limits braking performance and increases danger in emergency situations. Hyundai has carried out official recalls for this.

The Forward Collision Avoidance Assist (FCA) on the 2019 Tucson does not always work properly. Owners complain about false warnings from the forward collision warning system. The automatic emergency braking also works inconsistently. This leads to confusion and can undermine confidence in the system.

The lane-keeping assist also has weaknesses. Instead of making smooth corrections, the system sometimes lets the car weave between lanes. This feels unsettled and unreliable.

Recommendations for safety systems

• Check whether your Tucson is subject to a recall and have it carried out as soon as possible
• Do not rely entirely on driver assistance systems and stay alert yourself
• Report repeated false warnings to the dealer for possible software updates
• Test the performance of brake assist and emergency braking functions in a safe environment

Chassis, suspension and steering: noises and wear

Problems with the chassis and suspension are less common, but certainly not absent. Owners report unusual noises from the suspension, such as creaking or knocking when driving over uneven surfaces.

Abnormal wear patterns on shock absorbers and springs occur in older models. Intensive use on poor roads also accelerates this wear. The steering system generally appears reliable. There are, however, occasional complaints about play or odd steering behaviour.

These problems often only become noticeable after several years or at higher mileages. Regular inspection of the chassis and suspension during servicing is therefore sensible.

Braking system: wear and ABS issues

Abnormal brake wear does not occur more often on the Tucson than on comparable SUVs. However, there are reports of malfunctions in the ABS and ESP systems. These systems are important for safety. Faults require immediate attention.

Some owners report vibrations in the brake pedal or a spongy-feeling brake system. This may indicate air in the braking system, worn brake discs or problems with the brake fluid. Regular checks and timely replacement of wear parts prevent most problems.

Bodywork and interior: minor irritations

Although less critical than engine or transmission problems, there are various reports of bodywork and interior issues. Rattles in the interior occur, especially in older models. These are often caused by loose clips or trim panels that are not properly secured.

Water leaks through the roof also occur, often in models with a panoramic roof. This can cause moisture in the interior and in the long run lead to mould or rust. Thanks to improved protective coatings, newer Tucsons are less prone to rust. Older models sometimes show rust on parts such as wheel arches and sills.

Recalls: what do you need to know?

Over the years Hyundai has carried out several recalls for the Tucson. Important recalls concern loss of brake assist in models built between October 2018 and October 2020. This recall focuses on a braking system problem that can reduce braking performance.

Hyundai has also carried out recalls for engine-related issues, particularly for older models. Defective connecting rod bearings increase the risk of engine damage in these cars. Electrical systems and safety system software have also been the subject of recalls.

Always check whether your Tucson is subject to a recall by checking the registration number or VIN on the RDW website or directly with a Hyundai dealer. Recalls are carried out free of charge and can prevent serious problems.

Climate control system: air conditioning and heating problems

Air conditioning and heating problems affect various Tucson model years. Owners report systems that do not work, work intermittently or emit unpleasant odours when switched on.

These complaints have various causes, such as leaks in the air conditioning system, a defective compressor or clogged filters. Unpleasant smells often point to mould growth in the system, which can be prevented by regular cleaning.

Intermittent operation is often linked to electrical faults or defective sensors. Have climate control systems checked and serviced regularly to avoid more costly repairs.

Maintenance tips: prevent problems proactively

Many problems with the Hyundai Tucson can be limited or prevented through good maintenance and by being alert to early warning signs. Follow Hyundai’s service schedule closely and do not postpone inspections.

Pay particular attention to the following:

• Change engine oil and filters on time, especially with turbocharged engines
• Check transmission fluid regularly on DCT models
• Keep infotainment and safety system software up to date via the dealer
• Inspect the chassis and brakes annually or at every service
• Clean the air conditioning system annually to prevent odours and bacterial growth
• Check whether your model is subject to recalls and have them carried out

Where possible, use original parts or high-quality alternatives. Cheap imitation parts can cause new problems or shorten the lifespan of systems.

What should you do if a fault occurs?

Are you experiencing a problem with your Tucson? Then take the following steps.

First, note down exactly when the problem occurs. Also write down under which conditions it happens. Is it in cold or warm weather? At low or high speed? During acceleration or braking? These details help the mechanic with the diagnosis.

Have a fault read out as soon as possible using diagnostic equipment for fault codes. Many modern problems are stored in the car’s electronic memory. These fault codes provide clues to possible causes.

First visit an official Hyundai dealer, especially if the car is still under warranty. The five-year warranty with no mileage limit offers important protection. Carefully document all repairs and contacts.

Does the problem return after repair? Then request a thorough analysis in writing and stick firmly to your complaint. Some owners experience the same fault recurring, which points to an incomplete or incorrect repair.

Do you have persistent problems, or has warranty coverage been refused? This also calls for action. Contact a consumer organisation and consider legal advice. You have rights if major defects occur within the warranty period.

The balance: reliable with a few points of attention

The Hyundai Tucson is not an unreliable car, but the model does have specific weaknesses. These depend on the model year and engine variant. The DCT transmission, turbo engines and modern infotainment systems are the main concerns.

The five-year warranty with no mileage limit provides an important safety net and sets Hyundai apart positively from many competitors. The dealer can solve many problems with software updates and recalibrations. Not all owners are completely satisfied with how long these solutions last.

Where possible, choose reliable model years such as the 2008, 2009 or 2018 versions. Avoid the 2011, 2012, 2015 and 2017 models if you can, unless there is extensive service history and known problems have already been resolved.

Regular maintenance, proactive checks and quick action at early warning signs make the Tucson a reliable and pleasant car. Be aware of the weak points and do not let yourself be caught out by known problems that can be prevented.
