1. Toyota Highlander Years To Approach With Caution
Which Toyota Highlander years should you be cautious about? While the Toyota Highlander is generally a reliable SUV, some model years have had more issues than others. Being aware of these years can help you make a more informed decision when purchasing a new or used vehicle. The Toyota Highlander years to be more cautious about include:
- 2003
- 2008
- 2014
- 2015
These years have been identified as having more complaints and reported problems compared to other Highlander model years. According to customer satisfaction surveys in Boise, Idaho, in July 2025, understanding which models to avoid can potentially save you from future headaches and costly repairs. While these are the primary years to watch out for, there was also a period between 2010 and 2012 that experienced some concerns. These models aren’t necessarily as problematic as the ones listed above but may not be as durable or practical as the surrounding model years.
Should You Completely Avoid These Models?
Not necessarily. If you find a 2010 or 2012 Highlander at a great price and it comes with a thorough maintenance record, it could still be a worthwhile investment. However, it’s essential to do your due diligence and research any potential issues that might arise. Some common Toyota Highlander problems are relatively minor and manageable. However, other issues can be more severe and significantly impact the vehicle’s reliability and overall ownership experience.

2. Common Toyota Highlander Problems You Should Know About
What common problems plague certain Toyota Highlander model years? Understanding these issues can help you make a more informed purchase decision. Here are some of the most frequently reported problems with specific Toyota Highlander years:
2.1. Stripped Engine Bolts
Stripped engine bolts can be a serious issue. If not caught early, it can lead to significant engine damage. The initial signs often include coolant leakage and engine overheating.
What Happens?
When the engine bolts become stripped, they can no longer properly secure the engine components. This can lead to coolant leaks, causing the engine to overheat. Overheating, in turn, can lead to further damage and potentially require a complete engine replacement.
What Are The Repair Options?
In some cases, the bolts can be replaced, and the bolt holes can be re-drilled. However, this is only feasible if the engine hasn’t already sustained significant damage from overheating. Many owners have found that a total engine replacement was the only viable solution.
When Does This Issue Occur?
This problem is most commonly observed around 130,000 miles, but it can recur even after the initial repair. This makes it a significant concern for owners of affected model years.
2.2. Engine Failure
Engine failure, in general, is a major concern for Toyota Highlander owners. While it can be linked to stripped engine bolts and subsequent overheating, other underlying issues can also contribute to engine failure.
Why Is Engine Failure A Significant Issue?
Engine failure can result in the vehicle becoming inoperable, leading to costly repairs. This is a problem that not all car owners are willing or able to address, making it a critical factor to consider when purchasing a used Highlander.
What Should You Consider?
If you’re considering a Toyota Highlander from one of the problem years, assess your resources. Can you afford an engine replacement, or would you need to purchase a new car if the engine fails? This can help you make a more practical decision.
When Does Engine Failure Typically Occur?
Engine failure is most commonly reported around 120,000 miles, though it can sometimes occur earlier. While some Highlanders may surpass this mileage without issues, problems can still arise later on.
2.3. Excessive Oil Consumption
Excessive oil consumption is another issue reported by some Toyota Highlander owners. While many vehicles consume some oil, certain Highlander models tend to use more than average.
Which Models Are Affected?
Although this problem can occur in almost any Highlander model, it is more prevalent in the problem years. Interestingly, the 2002 model year is particularly known for burning through engine oil, despite being otherwise a solid car.
Is It A Deal-Breaker?
If you’re willing to add oil more frequently and monitor the levels, this issue might not be a major concern. However, if you’re considering a model year with other known problems, the excessive oil consumption can compound the overall ownership experience.
2.4. Fuel Tank and AC Condenser Problems (2020 Model)
The redesigned 2020 Highlander received generally positive reviews. However, it did have a couple of notable reliability issues.
What Are The Fuel Tank Issues?
Some owners reported that they could not fill the fuel tank to its advertised maximum capacity of 17.1 gallons. Instead, they could only fill it to about 12-14 gallons.
What Are The AC Condenser Issues?
Several reports indicated that the AC system could be unreliable. The AC condenser was prone to damage, which caused the AC to stop blowing cool air.
What Are The Potential Solutions?
The AC condenser can be replaced, which typically costs between $60 and $150, including labor. Toyota has acknowledged the fuel tank issue in the 2020 Highlander. Potential solutions involve dealer service actions to check for and rectify any fuel tank assembly or design anomalies, according to Toyota service bulletins.
2.5. Faulty Head Gasket and Oxygen Sensor (2001-2007 Models)
Engine overheating is a relatively common problem in the 2001-2007 Highlander models.
What Causes Overheating?
According to owner reports, the engine tends to overheat due to a blown head gasket. Upon closer inspection, the head bolts tend to pull the threads out of the engine block, eventually leading to a blown head gasket.
What Are The Oxygen Sensor Issues?
Several Highlander models have been reported to have faulty oxygen sensors. This defect causes the engine to misfire, resulting in rough idling.
How To Address These Issues?
Addressing these issues often requires significant repairs, including replacing the head gasket or oxygen sensors. It’s crucial to inspect these components when considering a model from these years.
