BLOG: Common Service Questions

Why is my check engine light on?Check Engine Light - also known as the Malfunction Indicator Lamp (MIL) is a signal from the vehicles engine computer telling the driver something is wrong.

If the light begins flashing, it indicates a more serious problem and in that case, it is strongly recommended to shut the vehicle off and call your Hyundai Dealership immediately.

The technicians at the dealership will diagnose the problem by hooking up a special tool to your vehicle to determine what code appears. The code tells them what the vehicle is reporting as malfunctioning.

Common reasons why your check engine light is on:

1. Loose or cracked gas cap: a loose or faulty gas cap can cause fuel to evaporate which can signal your check engine light. This is something you can check yourself
2. Replace Fuel Injectors
3. Replace Exhaust Gas Recirculation (EGR) Valve and Clean All EGR Ports
4. Replace Thermostat
5. Replace Spark Plug Wires and Spark Plugs
6. Replace Mass Air Flow (MAF) Sensor
7. Replace Ignition Coil(s)
8. Replace Ignition Coil(s) and Spark Plug(s)
9. Inspect for Loose Fuel Cap and Tighten or Replace as Necessary
10. Replace Catalytic Converter(s) with new OE Catalytic Converter(s)
11. Replace Oxygen Sensor(s) (O2s)

What's wrong with my car?

Common Complaints:

If your car seems to be vibrating at highway speeds it could indicate an issue with the balancing of your wheels. A licensed technician will diagnose the issue but in most cases, a wheel balance will solve the issue.

If your vehicle feels like it is pulling to the left or the right it could indicate your alignment is out. By having one of our technicians preform a wheel alignment, it could possibly solve the issue.

If your brakes are noisy, squealing or grinding, it could indicate low brake pads or warped rotors. By having your brakes serviced regularly you can avoid this issue.

Does your center unit (head unit) have no sound, no display or does your navigation not work at all? See your service advisor today as the head units are covered under warranty (3 years or 60,000km whichever comes first).

If your windshield is chipped or cracked you can come have it either repaired or replaced through our shop.

Why isn't my air conditioning cold?

It Needs Recharging:
The most common cause of an air conditioner not getting cold enough is that it needs to be recharged.

There's a Freon Leak:

Freon is the chemical that cools the air, so if there's a leak in the system, it will eventually run low or run out. Todays A/C systems are very sensitive. They require a specific amount of Freon, measured in pounds, to operate correctly. The proper way to check the system for the correct volume of Freon is with a charging machine. This device will first remove all Freon form the system then input the correct amount for proper operation. Freon leaks may be very, very slow. If you add more Freon and lose your cold air within a few weeks, however, you may need to have the hoses and other system components checked and replaced.

The A/C Compressor May Not Engage:

This problem can occur due to a variety of conditions. Failure can occur when there's an electrical fault in your compressor's circuit or clutch, Freon can be low or the vehicle can be overheating.
Today's cars are computer controlled and one of the first systems that is turned off when the computer senses an engine problem is the A/C system. Usually, the malfunctioning part has to be replaced by a qualified mechanic.

The Blend Air Door is Stuck:

There's a small hatch inside your car's ventilation system called the "blend air door". When you turn your environmental system from heat to cold, the door should change to drawing in cold air. If it doesn't change, it will still be drawing heat from the engine and blowing it on you! Again, this is a job for a qualified mechanic.

You Can Feel Cold Air, But It's Not Blowing:
This could mean the A/C's fan has stopped working. It may be as simple as changing a wire, or you may need a new fan unit. Again, this isn't something you can really change yourself, especially since it may require taking apart your car's dashboard to reach all of the components.

Should I repair or replace my car?

The choice is yours. Here are important things to consider:

- Is your vehicle becoming unreliable?
- Are the cost of recommended repairs, or mandatory safety repairs becoming greater than the value of your vehicle?
- Have major components failed, or are starting to fail (engine and transmission for example)?
- Are maintenance costs above what you would pay for a monthly car payment?

If so, it may be time for a new vehicle. You can meet with one of our sales consultants to calculate the cost of your trade and get you in a new ride in no time!

How long will my engine last?

There is no timeline on engines, can last up to 300,000km to 400,000 km. By following the vehicles recommended maintenance schedule and having regular oil changes done you can help keep your engine running smoothly and prevent many costly issues.

How long should my alternator last?

An alternator is the electrical component that keeps the battery system charged and provides electrical power to all accessories and ignition systems after vehicle is started and running.
Alternators have no timeline, but on average can last up to 10 years.

How do I know if it's failing?

If the dash lights are coming on and vehicle starts to loose power while driving then that would be one sign. A licensed technician can perform a charging test to see if your alternator is failing or not.

How long will my transmission last?

The transmission acts like the middle man between the engine and the wheels. Once a gear is selected (Drive, Reverse etc.) it transmits the power from the engine to the wheels At that point the vehicle either propels you forward or backward depending on the gear you're in.

There is no exact timeline on how long a transmission will last but here are a few tips to keep it operating smoothly.

By following the vehicles recommended maintenance schedule and having regular oil changes done you can help keep your transmission running smoothly and prevent many costly issues.

Do I need a new battery?

Signs you may need a new battery:

- engine seems having trouble to start (slower than usual when you turn the key)
- one day it may start fine, the next it may not
- you've already had to jump start it a lot
- car doesn't start at all, no crank, no auxiliary lights are on either
- check engine light may be on
- battery may be leaking or casing may be swelling

If you suspect your problem may be linked to the battery you can purchase a replacement battery and install it yourself if you're incline, or you may want to schedule a service appointment and have a license technician troubleshoot and replace it for you.

Common brake problems

1. brake noises/squeals - pads are low, pads have gone metal to metal, debris stuck in brakes. Using aftermarket parts can cause brake noise/squeals as well.
2. soft mushy brake pedal - brake worn low and out of adjustment, poor brake fluid condition/level
3. brake pulsations - caused by rotors warped, calipers sticking or seizing

Regular brake service can help detect the problem before it becomes a bigger issue.

Spot a water damaged vehicle

You would think a flood damaged unit would smell like mold and have rust and electrical problems right off the hop but that isn't always the case. Even if the engine runs good and the vehicle looks great, it could still potentially be a flood damaged vehicle. Corrosion can creep into some of the major components causing expensive repairs and potential injury to you or your loved ones inside. The best way to tell if the vehicle you're looking to purchase has water damage is to have a general inspection done on the vehicle before you purchase it.

It is illegal in Canada to resell a flood damaged unit as they are deemed a total loss once involved in any type of water situation. Buyers purchasing any pre-owned unit should always ask to see a carproof. More information on carproofs can be found here:

If you suspect your vehicle may have water damage please book a service appointment and have it inspected by a licensed technician to determine your safety. You can book your own service appointment online HERE!

Ways to increase fuel efficiency

- Don't be a NASCAR driver, slowly accelerate and decelerate at all stops to avoid using unnecessary fuel.

- Try not to idle your vehicle as much as possible (i.e. park and go into get a coffee rather than sitting in the drive-thru line up)

-Avoid installing aftermarket products such as light bars, roof racks, bike racks and side runners. These items create a drag effect as you propel forward and can increase the amount of fuel you burn on a daily basis.

Car smells and what they mean?

1. Musty old locker/smelly gross shoes - A dirty cabin air filter can smell like an old musty locker or smelly old shoe soles. The fix is quick, replace the cabin air filter and you will notice a considerable difference within a few days. Hyundai Canada recommends 15 thousand and 24 thousand kilometers. If the smell persists after a few days, a technician can blast out the A/C vents using a special spray to clear any mildew built up in the vents.

2. Rotten Eggs - Gasoline contains a trace amount of Sulfur. The bi-product it creates is called hydrogen sulfide (it smells like rotting eggs). If you are smelling this while the vehicle is running, you may have an issue with the catalytic converter.

3. Maple Syrup -when outside of your vehicle you may get a whiff of something sweet syrupy smelling. It could be your coolant leaking. Even though it smells pleasant, it is very toxic and should be addressed. If you smell it outside the vehicle it may just need something tightened or resealed. If the smell is more predominant inside the vehicle, it may indicated a bad heater core.

4. Fire and Brimstone - over time the gear lube can start to break down in the components gear housing or the transmission which creates the foul smell. Inspect any oil spills your car may be leaving behind. If it smells like sulfur then a visit to the service department is in order.

5.Moldy burning newspaper - if you smell this while driving, the smell is telling you it's time to replace the clutch.

6. Burning hair/acid smell - it is normal to smell this if you are driving under intense brake conditions however if you smell burning carpet under normal driving circumstances you may have a seized caliper piston. Having regular brake maintenance services can help you avoid this issue.

Battery maintenance tips

DO: start and run your vehicle at least once a week. If you cannot do this (maybe it's a summer driver) then we suggest putting the battery on a charger.

DON'T: run your vehicle in auxiliary mode for long periods of time (ex. Having the car stereo on while deep cleaning out the garage, or waiting for your mom who is STILL In the grocery store). This can kill your battery before you know it, resulting in having to boost your vehicle.

DO: refer to your owner's manual before attempting to jump start your vehicle

DON'T: just wing it when jump starting your vehicle, this could result in serious injury.

DO: Make sure the battery terminals are clean and free from corrosion.

DO: Unplug accessories and turn off lights when your car is turned off.
