The Toyota Yaris has earned a solid reputation for reliability and affordability. While it consistently receives high reliability ratings, like any vehicle, it has its share of common problems. This article delves into those issues, offering solutions and preventive measures to keep your Yaris running smoothly.
Reliability and Common Issues
The Toyota Yaris consistently ranks high in reliability. RepairPal gives it a 4.5 out of 5.0, placing it first among 21 subcompact cars. This excellent score is a result of the combined low average annual repair cost, infrequent need for major repairs, and low severity of issues. In fact, according to CarEdge.com, the Yaris depreciates only 24% after five years, which is impressive compared to other cars in the same category.
While the Yaris is generally dependable, some common issues have been reported across various model years. It’s important to remember that these issues don’t negate the Yaris’s overall reliability, and many have been addressed by Toyota through recalls and service campaigns.
Here’s a look at the most and least reliable Yaris model years:
Most Reliable:
- 2020 Toyota Yaris
- 2019 Toyota Yaris
- 2018 Toyota Yaris
- 2017 Toyota Yaris
- 2016 Toyota Yaris
- 2015 Toyota Yaris
- 2014 Toyota Yaris
- 2013 Toyota Yaris
- 2012 Toyota Yaris
- 2011 Toyota Yaris
The 2012-2018 models are particularly noteworthy, receiving a 4.6 out of 5 reliability rating from Kelley Blue Book.
Least Reliable:

These earlier models had more significant issues, including problems with airbags, ranging from exploding inflators in 2009 to non-deploying airbags in 2008.
Specific Problems and Solutions
Engine Issues
- Excessive Oil Consumption: Some older Yaris models, particularly those manufactured before 2015, may consume oil more rapidly than expected. This can lead to reduced engine efficiency and potential damage if not addressed. Regularly checking and topping up oil levels is crucial. If the issue persists, replacing piston rings or valve seals might be necessary.
- Rough Idling: Both petrol and hybrid models have reported rough idling, often caused by dirty throttle bodies or fuel injectors. Replacing fuel injectors or spark plugs can resolve this issue.
- Engine Cylinder Head Bolts: In March 2020, a recall was issued for certain Yaris models due to potential deformation of resin spacers caused by heat. This deformation could cause the engine cylinder head bolts to become loose, leading to engine damage. If your vehicle is affected by this recall, contact your Toyota dealer for inspection and repair.
Transmission Issues
- Automatic Transmission Problems: The 2009 Yaris is known for automatic transmission issues, such as grinding noises when shifting, a burnt smell, and delayed or unresponsive shifting. Some owners have also reported unexpected stalling after shifting gears. Addressing this may involve transmission fluid replacement, a complete transmission flush, or more extensive repairs.
- Semi-Automatic Gearbox Problems: Some Yaris owners have reported issues with the semi-automatic gearbox, including no response when in gear, unusual noises when changing gears, and shaking or grinding. This could be due to a gearbox oil leak or worn-out gear shift and clutch servos.
- Clutch Problems: Manual transmission Yaris models may experience premature clutch wear, leading to juddering when changing gears and potential clutch slippage.
Steering Issues
- Steering Malfunction: The 2007 Yaris has reported steering malfunctions, including sudden brake engagement and stiff steering, potentially increasing the risk of accidents. Other potential steering issues include a stiff steering wheel due to a faulty power steering control module (models manufactured between July 2011 and March 2012 were recalled for this issue) , and a loss of self-centering steering.
- Power Steering Failure: In some cases, the power steering system may fail completely, making steering very difficult. This could be due to problems with the power steering pump, fluid, or lines.
Brake Issues
- Brake Fluid Leak: Second-generation Yaris models manufactured between April and May 2013 could experience a brake fluid leak from the rear brake calipers or cylinders. This can result in increased stopping distances and reduced braking efficiency.
- Locked Rear Wheels: Applying the brakes suddenly in some early Yaris models may cause the rear wheels to lock, leading to instability and difficulty controlling the vehicle. Toyota issued a recall for this, involving replacing the brake proportioning valve.
- ABS Problems: Some Yaris models may experience ABS module malfunctions or sensor issues, triggering the ABS warning light.
Electrical and Safety Issues
- Speed Control Issues: The 2015 Yaris has a known issue with erratic speed control. Owners have reported sudden acceleration and unresponsive brakes.
- Faulty Airbag Inflators: The 2008 Yaris has a history of faulty airbag inflators that may explode, potentially injuring occupants with metal debris. This issue led to recalls in 2016, 2017, and 2019.
- Headlight Issues: Some Yaris owners have reported problems switching between high and low beams. This issue was the subject of a recall in 2002.
- Hybrid System Malfunction: A recall was issued in November 2022 for a software issue in the Toyota Yaris Hybrid system that could prevent the vehicle from entering a fail-safe driving mode, potentially leading to a loss of control.
Exterior Issues
- Premature Clear Coat Peeling: The 2007 Yaris is known for premature clear coat peeling, which can be unsightly and may lead to rust. This can be caused by UV damage, environmental factors, improper washing techniques, or poor-quality clear coat.
GR Yaris Issues
While the GR Yaris is generally a well-regarded performance car, some common issues have been reported by owners:
- Fake Engine Noise: Some owners have complained about the artificial engine noise generated through the car’s speakers.
- High Seating Position: The GR Yaris has a relatively high seating position compared to other hot hatches, which may not be preferred by all drivers.
- Impractical Back Seats: The rear seats in the GR Yaris are quite small and offer limited space.
- Frequent Servicing: The GR Yaris requires frequent servicing, with intervals of 10,000 km (6,200 miles).
Addressing Common Issues
Many of the common issues outlined above can be addressed through proper maintenance, timely repairs, and, in some cases, by taking advantage of Toyota’s recall and service campaigns. Here’s a more detailed look at how to address some of the most common problems:
Engine Mount Issues
Causes of Engine Mount Damage:
