A Guide to the Starter for the 2007-2019 Hyundai Sonata
Is your Sonata refusing to start? Learn to diagnose a failing starter and choose the right replacement.
- Before replacing the starter, always check the battery, terminals, and starter relay first to rule out simpler issues.
- A 'whirring' noise on a 2009-2013 Sonata likely means a broken starter lever, which can be fixed cheaply without replacing the whole unit.
- If you own a 2018 Sonata that won't start in the cold, check for a loose starter terminal nut as noted in TSB 19-EE-007H before buying a new part.
- For the best quality aftermarket replacement, choose an OEM supplier brand like Mando or Valeo for a guaranteed fit and performance.
Is Your Hyundai Sonata Starter Failing?
A failing starter can leave you stranded. Before you blame the battery, it's important to recognize the specific signs of a bad starter in your 2007-2019 Sonata. These symptoms often start intermittently but will get worse over time.
Common Failure Symptoms
- Single Loud Click: You turn the key, hear one loud click, but the engine doesn't crank. This usually means the starter solenoid is engaging, but the motor itself isn't turning.
- Rapid Clicking Noise: A series of fast clicks often points to a weak battery, but it can also happen if a failing starter is drawing too much power for the battery to handle.
- Whirring or Grinding Noise: If you hear a high-pitched whirring or grinding sound when you try to start the car, it often means the starter motor is spinning but its gear is not properly engaging with the engine's flywheel. This is a key symptom for a known issue in 2009-2013 models.
- No Noise at All: You turn the key and nothing happens, but your dashboard lights and radio work. This indicates the starter circuit is receiving power, but the starter itself is completely dead.
- Slow Engine Crank: The engine turns over very slowly, as if the battery is weak, even when it's fully charged. This suggests the starter motor is worn out and struggling.
- Smoke or Burning Smell: Smoke or a burning smell from under the hood can indicate an overheated starter, often from a short circuit or too many failed starting attempts. This is a serious sign and you should stop trying to start the car.
Known Issues & Technical Service Bulletins (TSBs)
Hyundai has issued official service bulletins for specific starter problems on the Sonata. Check if your car is affected before buying a new part.
- TSB 13-EE-001 (2009-2013 Sonata 2.4L): These models are known to have a plastic starter lever that can break. The main symptom is a whirring sound where the starter motor spins but does not crank the engine. A repair kit with just the lever is available, which is much cheaper than a full starter replacement.
- TSB 19-EE-007H (2018 Sonata 2.4L & 2.0L Turbo): Some of these vehicles may experience a no-crank condition, especially in cold weather. The cause is often a loose starter M-Terminal nut. The fix is to simply re-tighten the nut to the proper torque, not replace the entire starter.
Choosing the Right Aftermarket Starter
When shopping for a new aftermarket starter, it's helpful to think in terms of quality tiers. Not all brands are created equal, but a higher price doesn't always mean better for your specific vehicle.
Tier 1: OEM Supplier Brands
These brands are the original equipment manufacturers for Hyundai. They produce the exact same part that was installed at the factory, but sell it in their own box without the Hyundai logo. For a direct fit and factory quality, these are your best bet.
- Mando: Mando is a well-known Original Equipment (OE) supplier for Hyundai. Choosing a Mando starter is essentially buying the genuine part without the dealership price tag.
- Valeo: Valeo is another major OEM for Hyundai and Kia vehicles. Like Mando, a Valeo starter offers a guaranteed fit and long-term reliability.
Tier 2: Premium Aftermarket Brands
These companies are respected for their engineering and quality, often meeting or exceeding OEM specifications. They are a solid choice if an OEM supplier brand is not available.
- Bosch: A global leader in automotive parts, Bosch starters are known for their durability and performance.
- Denso: While more known for their role as an OEM for Japanese brands, Denso produces high-quality starters for a wide range of vehicles, including the Sonata.
Tier 3: Standard Aftermarket Brands
These brands offer a great balance of value and reliability. They are often remanufactured units, where wear components like brushes and bearings are replaced with new parts. They provide a cost-effective solution for getting your Sonata back on the road.

Pro Tip: Check the Relay First!
Before spending money on a new starter, check the starter relay, which is usually in the engine bay fuse box. A faulty relay can mimic the symptoms of a bad starter (like a no-crank, no-click situation) but is a much cheaper and easier part to replace. You can often swap it with an identical relay (like the one for the horn) to quickly test if it's the problem.
Frequently Asked Questions (FAQ)
How do I know if it's the battery or the starter?
If you try to start the car and the interior lights dim significantly or go out, you likely have a weak or dead battery. If the lights stay bright but the engine won't crank, the problem is more likely the starter. If a jump-start works, your battery is the problem. If it doesn't, the starter is the prime suspect.
What does the single "click" noise mean?
A single, loud click is the sound of the starter's solenoid activating and pushing the starter gear forward. The fact that it clicks means it's receiving power from the ignition. The lack of cranking after the click means the electric motor inside the starter has failed.
For my 2012 Sonata, can I just replace the broken lever?
Yes. For 2009-2013 Sonatas with the 2.4L engine, a broken starter lever is a very common problem addressed by Hyundai TSB 13-EE-001. You can buy a replacement lever kit for under $15 and replace just that part, saving you hundreds of dollars on a new starter assembly. This is a known weak point on these specific models.
How difficult is it to replace a Sonata starter myself?
For most 2007-2019 Sonatas, the starter is located under the intake manifold. This makes replacement a moderately difficult job. You will need to remove the air intake assembly, throttle body, and potentially other brackets to gain access. While it is feasible for a DIYer with some experience and the right tools, it is not a simple bolt-off, bolt-on job for a beginner. Expect it to take 2-3 hours.
