Engine Issues

Nu Engine Tick

One common problem with the Hyundai Elantra in Australia is the Nu engine tick. This issue often presents as a knocking or clicking noise that varies with the engine's revs. Drivers may also notice reduced power or hesitation, and in some cases, the engine may even seize or stall suddenly. Mechanics frequently report oil starvation issues, bearing wear, or metal debris in the engine oil.

Engine Bearing Failure

Engine bearing failure is another significant concern. Symptoms include a burning smell, oil leaks, and sometimes even smoke or fire. The 'check engine' or 'engine oil pressure' warning light may illuminate, indicating a serious problem. Regular maintenance and timely repairs are crucial to avoid these issues.

Oil Sludge Problems

Oil sludge can build up in the engine, leading to reduced performance and potential engine damage. This problem is often due to infrequent oil changes or using low-quality oil. To prevent oil sludge, it's essential to follow the manufacturer's recommended maintenance schedule and use high-quality oil.

If you experience any of these issues, it's advisable to consult a guide on filing safety complaints for vehicles to ensure compliance with standards and potential recalls.

Electrical System Faults

The Hyundai Elantra, like many vehicles, can experience various electrical system issues. A steady supply of power is crucial for the proper functioning of numerous components, making electrical problems quite common.

Malfunctioning Car Alarms

Car alarms in the Hyundai Elantra can sometimes malfunction, causing them to go off without any apparent reason. This can be both annoying and inconvenient for owners.

Ignition System Problems

Problems with the ignition system can prevent the car from starting or cause it to stall unexpectedly. This issue can be particularly frustrating and may require professional diagnosis and repair.

Battery Drain Issues

Battery drain is another common problem, where the battery loses its charge quickly. This can be due to various factors, including faulty wiring or components that continue to draw power even when the car is turned off.

It's important to stay updated on manufacturer recalls & service campaigns to address any potential safety issues related to the electrical system.

Steering Problems

The Hyundai Elantra has had its share of steering problems, with over 530 complaints reported. These issues can be quite serious, especially when they occur at high speeds or while using cruise control.

Power Steering Failure

One of the most alarming problems is the electronic power steering locking up. This can happen unexpectedly, making it difficult to control the vehicle. In 2017, Hyundai recalled some Elantras due to a faulty EPS connector, which could cause the power steering to shut down.

Steering Wheel Vibration

Drivers have also reported vibrations in the steering wheel. This can be due to various reasons, such as unbalanced tyres or issues with the steering column. It's important to get this checked out to avoid further complications.

Steering Column Noise

Another common issue is a knocking noise coming from the steering column. This is often caused by a faulty steering coupler. If you hear unusual noises while turning, it's best to consult a mechanic to diagnose and fix the problem.

Regular maintenance and professional inspection are crucial to ensure your vehicle's steering system is in good condition.

Suspension Problems

The Hyundai Elantra has faced several suspension problems over the years. One notable issue is the corrosion of suspension parts, particularly the front coil springs. In 2015, Hyundai recalled certain 2011 Elantra models because their front coil springs were prone to rust due to exposure to road salt. A rusty coil spring could break and puncture a nearby tyre, posing a significant safety risk.

Worn Out Shock Absorbers

Shock absorbers in the Elantra can wear out over time, leading to a less comfortable ride and reduced handling performance. This wear and tear can be accelerated by driving on rough roads or carrying heavy loads frequently.

Suspension Noise

Many Elantra owners have reported unusual noises coming from the suspension system. These noises can range from squeaks to clunks and are often a sign of worn or damaged suspension components. Regular maintenance and inspections can help identify and fix these issues before they become more serious.

Alignment Issues

Alignment problems are another common issue with the Elantra's suspension. Misaligned wheels can cause uneven tyre wear, poor handling, and reduced fuel efficiency. It's important to have the alignment checked regularly, especially if you notice the car pulling to one side or the steering wheel vibrating.

Brake System Concerns

Service Brake Problems

In 2017, Hyundai recalled over 33,000 Elantras due to a manufacturing issue. The problem was a dislodged diaphragm in the brake booster, causing a vacuum leak. This reduced the power brake assist, making it harder to stop the car. In some cases, the power brake assist failed completely.

Brake Pedal Response

A faulty brake booster can reduce the Elantra's braking power, increasing the distance needed to stop. This can be dangerous if the driver doesn't apply the brakes in time. Some 2013 models had issues with grinding noises while braking, traced back to bad brake pads and rotors.

ABS Malfunctions

ABS sensor problems can cause the brakes to lock up. Replacing the ABS sensor often solves this issue. However, some drivers noticed that their brake lights stayed on even when the pedal wasn't pressed. This was due to a deteriorating brake pedal stopper pad, which Hyundai recalled last year.

Regular maintenance and timely repairs are crucial to ensure your Hyundai Elantra's brake system works effectively.

Airbag Defects

Airbag Deployment Failure

One of the most serious issues with Hyundai Elantra airbags is their failure to deploy during crashes. This can be extremely dangerous as it compromises the safety of the driver and passengers. More than 1,130 separate problems related to airbags have been reported since the Elantra debuted in 1996. These issues include malfunctioning front airbag sensor controls and problems with the inflator.

Airbag Warning Light

Another common problem is the airbag warning light switching on and off without reason. This can make drivers worry that the airbags might not work properly when needed. It's crucial to address this issue promptly to ensure the safety of all vehicle occupants.

Recall Information

Serious airbag issues have led to multiple recalls for the Hyundai Elantra. For instance, a faulty front seat weight sensor can accidentally deploy the airbags in the 2006-2008 model years. Additionally, excessive pressure inside the airbags of the 2006 and 2007 models could cause them to deploy by accident. The Takata airbag recall also included some Elantra models, where faulty airbags could burst or deploy too slowly, putting the driver in danger.

When purchasing a used car, it's important to check for recalls before buying. This is especially true for the Takata airbag recall. Use tools like Carify to check for recalls before making a purchase.

Transmission Issues

Transmission Slipping

One common problem with the Hyundai Elantra is transmission slipping. This can cause the car to shudder or hesitate when changing gears. Drivers might also notice a burning smell or see the 'check engine' light come on. If you experience these issues, it's best to get your car checked by a mechanic.

Gear Shifting Problems

Another issue is difficulty with gear shifting. This can include knocking or clicking noises, especially when the car is revving. Sometimes, the car might even stall or stop suddenly. These problems can make driving unsafe, so it's important to address them quickly.

Transmission Fluid Leaks

Transmission fluid leaks are also a concern. If you notice fluid under your car, it could be a sign of a leak. This can lead to reduced power or hesitation while driving. Regularly checking and changing the transmission fluid can help prevent this issue.

If you notice any of these problems, it's crucial to take your car to a reliable mechanic. Ignoring these issues can lead to more serious damage and higher repair costs.

Conclusion

In summary, while the Hyundai Elantra offers a range of appealing features, it is not without its share of common problems.
