🚫 Do not drive — If the starter has failed, the engine will not be able to start, leaving you stranded.
Key Takeaways
  • The original starter is a high-quality Denso unit; an aftermarket Denso is the best replacement option.
  • Failure symptoms often include a single click with no crank, intermittent starting, or slow cranking with a good battery.
  • Replacement is moderately difficult as the starter is located under the air intake and battery tray, increasing labor time.
  • Always test the battery and check for corrosion before assuming the starter has failed, as symptoms can be identical.
The starter in your Lexus ES350 is a small but powerful electric motor. Its only job is to turn the engine over so it can start running on its own. When you press the start button or turn the key, the starter motor gets power from the battery. It then pushes a small gear forward to engage with a large gear on the engine's flywheel, spinning the engine until it fires up. Once the engine is running, the starter disengages and waits for the next time you need it.

Is Your ES350 Starter Failing? Common Symptoms

A starter problem on the 2007-2019 Lexus ES350 usually gives you some warning. Before it fails completely, you might notice one or more of these signs. It's important to distinguish between a bad starter and a weak battery, as the symptoms can be similar.

  • Single, Loud Click: When you try to start the car, you hear a single, solid "click" but the engine doesn't turn over. This often means the starter's solenoid is working, but the motor itself is not.
  • No Sound at All: You press the start button and nothing happens. No click, no crank. While this could be a battery or ignition switch issue, it can also point to a completely dead starter or a problem in the starting circuit.
  • Slow or Labored Cranking: The engine turns over much slower than usual, as if the battery is weak. If you've confirmed your battery is good, the starter motor may be wearing out and drawing too much power.
  • Intermittent Starting: The car starts fine one day but refuses to crank the next. This can be caused by worn-out electrical contacts inside the starter, which is a common failure point on these Denso units.
  • Grinding Noise: A grinding sound during or after the engine starts can indicate a problem with the starter gear not disengaging correctly from the engine's flywheel.

Don't Mistake a Bad Battery for a Bad Starter

Many starting problems are caused by a weak or dead battery, or corroded battery terminals. Before replacing your starter, always have your battery tested and clean the terminals. 🎬 Watch this guide on how to diagnose your starter like a pro. A battery can sometimes have enough power to run lights and radio but not enough to turn the powerful starter motor.

Known Issues, Recalls, and Service Bulletins

The starter system on the Lexus ES350 is generally very reliable. Searches for official recalls from the National Highway Traffic Safety Administration (NHTSA) for the 2007-2019 model years did not show any recalls specifically for the starter motor. Likewise, there are no widespread Technical Service Bulletins (TSBs) pointing to a common factory defect with the starter itself. Most failures are due to normal wear and tear over many years and miles.

Choosing the Right Aftermarket Starter

Choosing a premium brand like Denso or Bosch ensures your ES350 receives an OEM-equivalent part designed for the same longevity as the factory original.

The original starter on your ES350 is made by Denso, a brand that is partially owned by Toyota and known for its high quality. When choosing a replacement, you have several options with varying levels of quality and price.

Brand TierBrandsQuality & Notes
Premium Aftermarket (OEM Equivalent) Denso, Bosch A new aftermarket Denso starter is your best bet for original quality and longevity. It's made by the same company as the factory part, ensuring perfect fit and performance. Bosch is another top-tier brand that makes excellent new and remanufactured starters, often considered on par with Denso.
Quality Aftermarket Remy, WAI Global Remy is a well-known aftermarket brand that generally offers good quality parts, though some users report mixed long-term reliability. WAI Global is another large aftermarket supplier. Quality can be comparable to other mid-tier brands, but like any non-OEM part, longevity can be a gamble.
Standard / Economy BBB Industries, Store Brands BBB Industries is a major remanufacturer that supplies many auto parts stores with their house brands. These starters are often the most affordable option, but quality can be inconsistent. They are a viable choice if budget is the primary concern, but may not last as long as a premium unit.

A Note on the 2019 Lexus ES350

The 2019 model year marked the beginning of a new generation for the ES350, featuring a different engine (2GR-FKS) than the 2007-2018 models (2GR-FE). While the starter's function and location are similar, the specific part number may be different. Always verify the part fits your exact year, make, and model before ordering.

The starter on the ES350 is located on the top of the transmission housing. Accessing it requires removing several intake components, which contributes to the labor cost.

Replacing the starter on the ES350 is a moderately difficult job because of its location. The starter is located on the top of the transmission, underneath the airbox and battery tray. This means several components must be removed to gain access, which increases labor time.

Frequently Asked Questions (FAQ)

Is it hard to replace the starter on a Lexus ES350?

For a DIYer with some experience, it's a manageable job. It does not require lifting the engine, but you will need to remove the battery, battery tray, and the entire air filter box assembly 🎬 See a step-by-step video on Lexus ES350 starter replacement. to access the starter. You'll need basic hand tools like 10mm, 12mm, and 14mm sockets and a ratchet. The job can take a couple of hours for someone who is familiar with this type of work.

Should I buy a new or remanufactured starter?

For this vehicle, a new starter from a premium brand like Denso or Bosch is highly recommended. While a quality remanufactured unit can be good, the labor to replace the starter is significant enough that you don't want to risk having to do the job twice due to a faulty part. Even starters from the dealership are often remanufactured by Denso.

What is the starter relay and could that be the problem?

The starter relay is a small, inexpensive electrical switch in the fuse box that sends power to the starter when you start the car. On Toyota and Lexus vehicles, it is often a distinct purple color. If you have a no-crank situation, a faulty relay could be the cause. It's a much cheaper and easier part to replace than the starter, so it's worth considering as a diagnostic step.

🎬 Troubleshoot a no-crank issue even after replacing the starter.
My car clicks but won't start. Is it the starter?

A single, loud click usually points to the starter solenoid engaging but the motor failing to spin. However, a rapid series of clicks often indicates a battery that is too weak to turn the engine over. Always test the battery first to rule it out.
