While many people focus on the Big Three when choosing a truck, there is a strong market for the 2020 Toyota Tundra. The automaker claims that this truck is “built to go the distance,” but some drivers wish they had made a different choice. In fact, this model is having trouble with the exterior lighting, service brakes and steering.

Problems with the Headlights?

Seeing clearly on the road should be a top priority, but the Tundra seems to utterly fail on this level.

Here’s one NHTSA review that illustrates some of the troubles. “Front turn signal bulbs are too dim to view during daylight operation. This creates a very serious, avoidable accident risk while oncoming traffic cannot clearly observe turn signal indicators during daylight hours.”

It turns out that this is more than just a complaint, but a true safety concern. Even the automaker was forced to recognize it with a recall. NHTSA Campaign Number 20V41000 states that nearly 200,000 vehicles are equipped with LED headlights with faulty wiring. Because of this defect, the front turn signals don’t run as brightly as they should. This problem could lead to people not seeing when the truck is turning and might cause an accident. Basically, the Tundra is made “to go the distance,” as long as that means simply driving in a straight line.

Problems with the Brakes?

Another vital safety aspect is the service brakes. This system must be in properly working condition to stop the truck before an accident occurs. However, there are multiple problems on this level as well.

One NHTSA complaint states, “The contact owns a 2020 Toyota Tundra. The contact stated that while driving at 6 mph, an abnormal sound was heard coming from the vehicle. The vehicle was taken to [dealership] to be diagnosed said it was the ABS actuator. The mechanic was unable to provide a cause for the failure. The vehicle was not repaired. The manufacturer was contacted but no further assistance was provided. The failure mileage was 800.”

While Toyota isn’t issuing any statements about these problems, there has been one communication about trouble with the brakes after long-term storage. Service Bulletin T-SB-0009-19_Rev also lists other parts that might suffer degradation as a result of storage. Apparently, the Tundra is only made to drive, which is why the company chose the tagline. If a customer wants to store it, it might not be ready to go the distance afterward.

Problems with the Steering?

Whatever is strong and powerful, should also be controlled and harnessed. That’s why a reliable pickup truck must also come with functional brakes, but that’s not the case with the Tundra.

No one expects a truck to handle like a sports car, but it should be able to remain on the road. Yet, owners are struggling with the steering wheel to put it where it needs to be.

An Edmunds review states, “What’s up with new truck driving not straight like F150, Chevy or Ram? Even Honda Ridgeline drives straighter without constant fine tuning. The 2nd replacement potential truck..same issues..won’t drive straight without constant, micro adjustment. Drive F150 and see the difference in Tundra..other rv tow people or without tow long hwy drive people know what I’m talking about. City dwellers may not understand as it’s not noticeable. But long drive.. it’s very apparent.”

While this sounds like a serious concern, Toyota has brushed right over it, by providing information on a much smaller problem. Service Bulletin #T-TT-0578-19 says that there are Bluetooth connectivity issues with the steering wheel controls. It turns out that drivers are having trouble pairing their devices with the functions, but the automaker ultimately blames the phone companies for making changes on their end. Hopefully, no one is hoping to “go the distance” with their favorite tunes at their fingertips.

Description
Note: toyota has confirmed this issue, but is unable to resolve this. When the sos button is pressed, the dcm module is supposed to send the proper vin number and location to the call center. The call center does not receive the proper vin number and pulls up the wrong person / location. In my case, if an emergency occurred, they would send emergency assistance to a vehicle located in another state entirely. This is not because the wrong owner is assigned to their system. They can find my vehicle vin with the proper owner information in their system. The issue is that the dcm module (or other system) is actually sending the wrong vin to their system. The toyota sos call center says to see the dealer and the dealer says they are unable to fix this. If this is not isolated to just my vehicle, this could cause a loss of life if emergency assistance never arrives at the proper vehicle location.

Air conditioning compressor partially seizes if air conditioning is turned on while driving and when air conditioning knob is on at time engine is started. Makes very loud noise. When driving, and it occurs, truck will slow suddenly as if the brakes were applied until compressor engages. Dealer mechanic says it sounds like the compressor clutch engaging. Said nothing wrong. Have left truck with dealer several times and they say they cannot replicate the issue. I've recorded the sound several times and have played that to them. They hear it but say that they have to prove that is what is happening. They refuse to replace the compressor. Vehicle is not safe to drive when this happens. This has occurred since truck was purchased brand new.

Vehicle stalled and lost power at approximately 45 mph. Warning lights activated and "not ready to drive" message was displayed. Vehicle has had 3 other similar episodes all resulting in the vehicle losing power at high speed. Vehicle was towed to local toyota service dept. Where they said it generated a code for rough idling - low fuel. They did no repairs and offered no explanation. Three miles from the dealership the tundra died in traffic. The safety of my family was certainly at stake and had my wife been driving the vehicle she likely couldn't have steered the vehicle to safety. These are not low speed failures, but rather high speeds.

I bought a 2020 tundra in mid year of 2020. By december 2020 I started to notice a strong vibration in the steering and from the front end between the low speeds of 20-30 mph and between 60-70 mph. The hotter the vehicle gets the more vibration occurs. Now my alignment seems off and curves to the left when trying to drive straight. I have taken it in to alamo toyota and red mccombs in san antonio on many occasions with similar problems but all they are doing is balancing and rotation of tires. I have sent the dealership videos of the vibration but they indicate it's normal. This certainly does not appear normal and is now more of a safety issue. Not sure what else to do!

I accelerated from a stop making a right turn in a normal manner to keep safely in front of oncoming traffic, I had no power although I kept pushing the accelerator. Multiple lights flashed on the dash. I coasted to the shoulder of the road. After I stopped, all the lights on the dash had gone out but the engine was still running. It responded normally after that. Dealership said a communication code showed but was not related to my issue. I had three other "loss of power incidents" since all at low speed, either starting from a stop or attempting acceleration after a turn. The yellow triangle flashed those times but traffic did not allow me to keep pushing on accelerator. After a short coast power returned. Dealership reported no code. Experience similar to description of behavior of vehicles in toyota fuel pump recall. I believe it is the fuel pump. Dealership and toyota customer service tell me I must drive it until it "fails" and shows a code. Safety issue, accident waiting to happen.

Description
We purchased a brand new tundra and from the minute we drove home there seemed to be a bounce or vibration like running over rumble strips in the front end. We then noticed the bed was mounted to the passenger side by about a half an inch which to me tells they didn't do a very good final check before it left the factory. We took it to the shop and they tried four different tires and the mechanic stated it actually made the vibration worse. Each of three times it was in the shop that they tried to rectify the situation they re aligned the truck. I wondered why each time without much driving and no off road diving it was out of alignment three times within one or two months. An independent mechanic I had a casual conversation with said if they don't find and fix the actual mechanical problem such as a bad cv joint it will go out of alignment as soon as you drive out of the shop. The safety issue that makes it very scary to drive is the truck wanders or floats to the right while driving or braking and at times when braking the steering wheel turns right severely by itself while the truck continues to travel straight. The more you drive and the warmer everything gets the worse it gets. It will even drift right from the wrong side of the road proving it is not due to the crown of the road. It will travel completely right from the farthest point left. The service manager stated he felt what we were describing but that it might be a characteristic of that truck and wanted specialists from toyota to come to the shop to try to locate the exact cause rather than throwing parts at it and never locating the actual problem. Toyota has not offered any assistance to him or us as of yet. We can not drive this truck without feeling we are in danger. We owned a 2015 tundra prior that had no problems at all. Upon researching we are not the only people experiencing these exact issues.

When weather gets warm (100f+), it will often take a few seconds to start the car. It cranks over, but won't catch. When weather gets to 110f, it would fail to start after it has been driven, then parked. Wait 90 minutes, and it would starts again. This is a safety issue, because when weather is 110f+, it is very very uncomfortable waiting for a tow truck (they are usually super busy on a hot day) or wait 90 minutes plus in 110f+ weather. Toyota has refused to fix it, as they say they need to wait for a 110f+ day to duplicate the issue,

Upon filling up with fuel at various fuel stations, when the pump shuts off and is removed from the filler neck, fuel begins to come back out the filler neck and pour out onto the vehicle and ground. Vehicle only has 2000 miles on it and has done this from day one. The spills have ranged from a cup full to half a gallon making a hazardous and potentially deadly situation. Another dealer in nm advised some toyota vehicles have done this due to a defective overflow valve in the fuel tank. My local dealer has had me return several times even though I have video evidence of the defect. Toyota usa has also not been helpful with trying to fix the problem.
