The Toyota Tundra is built with power, durability and capability in mind. However, even the most robust trucks require maintenance and repairs over time. At Fremont Foreign Auto, we want to educate Tundra owners on some of the most common issues you may encounter so you know what to watch out for. Read on to learn about frequent problems and how our expert technicians can get your truck back on the road.
Transmission Troubles
One of the most reported problems by Toyota Tundra owners, especially those with models from 2007-2015, is transmission issues. What symptoms might tip you off to problems with your Tundra’s transmission? Drivers often notice harsh shifting between gears, delayed engagement when shifting, gears slipping, or the truck lurching forward unexpectedly. These troubles typically start with a faulty throttle position sensor that sends incorrect signals to the transmission control module. The skilled technicians at Fremont Foreign Auto can diagnose what’s wrong with your Tundra’s transmission by replacing the throttle position sensor. This ensures buttery smooth shifting so you can tow heavy loads with confidence once again.
Exhaust Manifold Leaks
Tundras with the 4.7L V8 engine, particularly those from 2005-2008, are prone to developing exhaust manifold leaks over time. What does the exhaust manifold do? This important part routes burned gases from the combustion chamber to the exhaust pipe and the rear of your truck. When cracks form due to extreme temperature changes, leaks can occur. Watch out for symptoms like:
- A ticking sound coming from under the hood
- Reduced engine power and performance
- Potential damage to other systems like the catalytic converter
The technicians at Fremont Foreign Auto have years of experience inspecting exhaust systems to pinpoint leaks. We can then repair cracks or replace the faulty manifold completely to restore proper exhaust flow. This keeps your Tundra running strong for years to come.
Failing Secondary Air Injection System
The secondary air injection system helps reduce emissions by routing air into the exhaust stream to burn unspent fuel during cold starts. Problems with this system typically affect Tundras made from 2007-2013. Signs of issues include:
- Illumination of the check engine light
- Rough idling
- Stalling, especially when cold
The most frequent culprit is a seizing or failed air injection pump. Our technicians can diagnose what’s wrong with your secondary air injection system. We’ll replace the pump and any connected hoses or valves that may be damaged. This keeps your emissions within acceptable ranges for a cleaner run.
Oil Leaks from Camshaft Towers
In 2007-2011 models with the 5.7L V8, we often see oil leaks coming from the camshaft towers. What are camshaft towers? They house the bearings that allow smooth rotation of the camshaft to operate the engine’s valves. When O-rings or gaskets in this area fail, oil can drip down and potentially damage other components. Catching these leaks early is key to preventing costlier repairs down the road. The technicians at Fremont Foreign Auto will pinpoint the exact source of any oil leaks. We can then replace worn seals and gaskets to stop leaks in their tracks.
Worn Out Lower Ball Joints
Ask any Toyota Tundra owner and they’ll tell you these trucks are made to last. However, the lower ball joints are prone to premature wear, especially in models from 2007-2015. Ball joints connect the control arms to the steering knuckles. This allows the wheels to smoothly turn when you change direction. If you hear clunking from the front suspension, notice uneven tire tread wear, or feel looseness in the steering, worn ball joints may be the culprit. Driving with severely damaged joints can lead to catastrophic failure and loss of control. The technicians at Fremont Foreign Auto thoroughly inspect the ball joints on your Tundra. We’ll replace them promptly to restore safe handling and prevent further suspension damage down the line.
Oxygen Sensor Failure
Modern vehicles rely on oxygen sensors to monitor exhaust gases so the engine computer can adjust the air-fuel ratio for optimal efficiency. Most Toyota Tundras have four sensors, one for each exhaust manifold. Over years of use, they eventually fail. Warning signs include:
- Reduced gas mileage
- Rough engine running
- Potential catalytic converter damage from unburned fuel
Since oxygen sensors tend to degrade slowly over time, it’s tricky to diagnose which one needs replacement. The technicians at Fremont Foreign Auto use advanced computerized testing to determine which sensor is no longer functioning properly. We’ll replace only the faulty one to restore strong performance and fuel economy while saving you money.
Faulty Ignition Coils
The ignition coil on your Toyota Tundra is responsible for providing a strong electrical charge to each individual spark plug. Coils can fail as they endure heat cycling over thousands of miles. Symptoms of bad coils include:
- Flashing check engine light
- Engine misfires or hesitation
- Loss of power and poor acceleration
- Excessive vibration or shaking
In a worst case scenario, a damaged coil can lead to catalytic converter failure from raw fuel passing through. Our expert technicians thoroughly test the ignition coils on your Tundra. We’ll promptly swap out any faulty ones and ensure the entire system is operating correctly. This restores smooth running and prevents further damage down the line.
Ongoing Maintenance is Key
While Toyota Tundras are incredibly rugged and reliable trucks, they still require periodic maintenance and repair as parts wear out over time. We hope this overview has helped educate you on some of the most prevalent issues Tundra owners face. Keep up with factory recommended services, and don’t hesitate to bring your truck to Fremont Foreign Auto at the first sign of trouble. Our team has the knowledge and dedication to accurately diagnose issues and get you back on the road.
