A Guide to Replacing the Starter in Your 2010-2022 Toyota Highlander
Experiencing starting issues with your Highlander? This guide covers common symptoms and how to choose the right new aftermarket starter.
- A single, loud click is the classic symptom of a bad starter, while rapid clicking usually points to a weak battery.
- Denso is the Original Equipment Manufacturer (OEM) for many Toyota starters; choosing a new Denso is a reliable option.
- Replacement is much more difficult on V6 models because the starter is located under the intake manifold, increasing labor time and cost.
- There are no major recalls or TSBs for starter failure on the 2010-2022 Highlander; it is a standard wear item.
Is Your Highlander's Starter Failing?
A starter motor usually gives warning signs before it fails completely. For the 2010-2022 Toyota Highlander, these symptoms are often mistaken for a bad battery. Knowing the difference can save you time and money.
OEM vs. New Aftermarket Starters
When replacing your starter, you have a few options. An OEM (Original Equipment Manufacturer) starter from Toyota is the same part your vehicle was built with. Denso is the original supplier for many Toyota starters, so choosing a new Denso part is like getting an OEM part without the dealership price tag.
High-quality new aftermarket starters from reputable brands offer a reliable and cost-effective alternative. They are designed to meet or exceed original specifications and are a smart choice for a vehicle like the Highlander, which is not known for being unusually hard on its starters.
Pro Tip: Always check your battery first! A rapid clicking sound when you try to start the engine is a classic sign of a weak or dead battery, not a bad starter. A single, loud click is more indicative of a starter problem.
Choosing the Right Aftermarket Brand
Not all aftermarket brands are created equal. Here’s a look at the brands available for your Highlander:
- Denso: As an OEM supplier for Toyota, Denso offers the highest quality and a guaranteed fit. If you want OEM performance, this is the top choice.
- Bosch: A globally recognized OEM supplier for many carmakers, Bosch produces high-quality new and remanufactured starters that are built to last and perform reliably.
- Remy: Remy has a long history in automotive electrical parts and is a well-regarded aftermarket brand. Many owners and mechanics have had good success with their new and remanufactured starters.

Known Issues, Recalls, and Service Bulletins
There are no widespread recalls or technical service bulletins (TSBs) from the National Highway Traffic Safety Administration (NHTSA) for starter motor failure on the 2010-2022 Toyota Highlander.

Frequently Asked Questions (FAQ)
How difficult is it to replace a Highlander starter myself?
The difficulty depends heavily on your engine. For 4-cylinder models, the starter is often easily accessible on top of the transmission 🎬 Watch this step-by-step guide for replacing a 4-cylinder Highlander starter., making it a straightforward job for a DIYer with basic tools. For the 3.5L V6 engine, the job is much more complex. The starter is located under the intake manifold, which must be removed for access. This is an advanced DIY job that can take 3-5 hours.
What's the difference between a new and a remanufactured starter?
A new starter is made with all-new components. A remanufactured starter is an original starter that has been rebuilt. It's disassembled, cleaned, and worn components are replaced. High-quality remanufactured parts from brands like Bosch or Denso can be a good value, but new parts from the same brands offer the longest potential lifespan.
Do I need a special starter for a Highlander with an auto stop/start system?
Yes. Later model Highlanders with the automatic engine stop/start feature place more demand on the starter. You must use a replacement starter specifically designed and rated for stop/start (or "stop-go") applications to ensure durability and proper function.
How long should a starter last on a Toyota Highlander?
An original starter can last 100,000 to 150,000 miles or more. Lifespan depends on driving conditions, such as the number of starts per day and climate. Starters on vehicles with auto stop/start systems may have a shorter lifespan due to more frequent use.
