The Toyota 4Runner is a mid-size SUV that has been around since the early 1980s and has been praised for its reliability and capability on and off the road. It’s known for its great towing capacity, off-road handling, and rugged looks. However, like any vehicle, the 4Runner does have some common problems.
One of the common issues with the 4Runner is its fuel economy. The 4Runner gets an EPA-estimated 17 MPG in the city and 20 MPG on the highway. This is not the best fuel economy in the mid-size SUV class and can be a downside of owning the 4Runner. It also has a large engine, so it can be a bit more expensive to maintain compared to smaller SUVs.
The 4Runner also has some issues with its transmissions. The automatic transmission sometimes has trouble shifting and can be noisy. The manual transmission can also be a bit difficult to use due to the design of the shifter.
Another common issue is the 4Runner’s suspension. The suspension can be a bit on the stiff side, causing the ride to be a bit rough at times. The suspension can also be a bit noisy, especially when driving on rough roads.
One final issue is the 4Runner’s brakes. The brakes can be a bit squeaky and are prone to wear out quickly. This can be an issue if you are driving in a lot of stop-and-go traffic.
Overall, the Toyota 4Runner is a great SUV and has proven itself to be reliable and capable both on and off the road. However, like any vehicle, it does have some common problems that owners should be aware of. It’s important to keep an eye on the fuel economy, transmission, suspension, and brakes to ensure your 4Runner is running smoothly.

If you’re experiencing any of these problems, it’s a good idea to have your brakes checked by a professional. It could be a sign of worn brake pads, warped rotors, or a faulty caliper.
Suspension Issues
The suspension system is responsible for providing a comfortable and stable ride, and if it’s not working properly, your 4Runner may not handle as well as it should. Common suspension issues include clunking or creaking noises, uneven tire wear, instability when cornering, and a rough ride. These issues could be caused by a variety of problems, including worn shocks or struts, worn suspension components, or a faulty tie rod.

Solving Performance Issues With Toyota 4Runner
The Toyota 4Runner is a popular SUV model that has been part of the Toyota lineup since 1984. It is a favorite of off-roaders and weekend adventurers alike due to its ruggedness and dependability. Unfortunately, as with any vehicle, there can be performance issues that arise with the 4Runner. These can range from minor engine issues to more serious mechanical problems.
The most common problem associated with the Toyota 4Runner is a faulty mass air flow sensor. This sensor monitors air intake and helps the vehicle control its emissions. A faulty mass air flow sensor can result in a variety of issues for the 4Runner, including reduced performance, poor fuel economy, and acceleration issues. Additionally, it can also cause the vehicle to run rough and may even lead to engine stalls.
Another problem that can affect the 4Runner is a defective oxygen sensor. The oxygen sensor in the 4Runner is responsible for monitoring the exhaust gases in order to maintain efficient fuel combustion. A faulty oxygen sensor can cause the 4Runner to experience reduced power, poor fuel economy, and black smoke from the exhaust. If left unchecked, a faulty oxygen sensor can lead to increased emissions and even engine damage.
The most effective solution for addressing performance issues with the 4Runner is to have the vehicle inspected by a qualified mechanic. A professional inspection can identify problems such as a faulty mass air flow sensor or a defective oxygen sensor. Once the cause of the problem has been identified, the mechanic can advise on the necessary repairs. Depending on the extent of the issue, repairs may involve replacing parts, such as the mass air flow sensor or oxygen sensor, or may require more extensive work.
The cost of repairing performance issues with the 4Runner can vary depending on the nature of the problem and the parts that are necessary for the repair. Generally, most repairs are relatively affordable and can range from $100 to $400. However, more extensive repairs can cost upwards of $1,000.
In conclusion, performance issues with the Toyota 4Runner can range from minor engine issues to more serious mechanical problems. The most common issues are typically related to the mass air flow sensor or the oxygen sensor. The best solution for addressing these issues is to have the vehicle inspected by a qualified mechanic. Depending on the extent of the problem, repairs can cost anywhere from $100 to $1,000.
