2021 Toyota Tundra Problems and Top Complaints – Is Your Car A Lemon?

Engine & electrical system among the top complaints received by the NHTSA from vehicle owners

In the tight race between pickup trucks, the 2021 Toyota Tundra continues to gain popularity among consumers. The automaker claims this truck helps drivers “go the distance,” but customers don’t agree. There are regular complaints about the seats, engine and electrical system that seem to be holding this model back from reaching its true potential.

Problems with the Seats

While trucks are meant to get a job done, there’s no reason to be uncomfortable while riding in one. Yet, there have been numerous people discussing how hard it is to sit in the seats.

One such complaint can be found on the Edmunds website. “My boyfriend just bought a brand new (500 miles) Tundra SR5 and I am trying to be supportive because it is a gorgeous truck. White, lifted with black rims. Beautiful. However, we’re in an argument right now because my legs are going numb from sitting in the passenger seat. It has nothing. Not even the lever that lets you raise and lower it. Which, working at Enterprise, I know is on basically every other brand new vehicle. For the money he paid, I should not be sitting here, halfway sliding out of this perfectly horizontal seat, with no way of fixing it. I’m literally looking up seat covers with inserts that will raise my legs up so I won’t be so uncomfortable. Definitely don’t recommend this truck to anyone who wants any kind of bells and whistles, or even someone vertically challenged.”

It turns out that the Tundra wasn’t made of the highest-level of quality from any angle. Service Bulletin #T-SB-0012-21 discusses how paint stains and wrinkles can appear under the Rapgard when it is removed. The wrinkles are also trapping water, which is leading to additional moisture issues of the trunk, roof and hood. With this in mind, it doesn’t appear that the structure of the Tundra can actually “go the distance.”

Problems with the Engine

When it comes to Tundra engines, there have been plenty of them, but not all have been reliable.

On the Tundras.com website, this remark was made. “The Tundra came with many engine options including the 1GR-FE 4.0L V6 the 2UZ-FE 4.7L V8 and the 4.6 and 5.7 UR-FE engines. Most notable issue on the 5.7 is the broken valve springs and the leaking cam towers.”

It turns out that class-action lawsuits have been investigated because of the cam tower and camshaft seal leak situation. Since 2010, Tundra trucks have been built with a defect that causes the seals to wear out sooner than they should. With all these years in play, one would think that Toyota would have fixed the problems by now, but that doesn’t seem to be the case. Because of the defects, there are lots of Toyota owners that should be receiving compensation if they can “go the distance.”

Problems with the Electrical System?

It also appears that the 2021 Toyota Tundra models are built with some electrical system defects that need to be discussed.

Another complaint left with Tundras.com states, “Electrical issues including radio issues and issues with aftermarket remote starters.”

Actually, there’s a pretty remarkable electrical system defect causing a recall on Tundra trucks. NHTSA Campaign Number 21V688000 says that more than 158,000 models might have a headlight circuit that powers both the high and low beams at the same time. This defective electrical connector can overheat and lead to a truck fire. At this point, it might not be a terrible thing if the Toyota truck burned into a heap of dust.
