Which Is the Most Reliable Full-Size Truck? [Ranked for 2021]

Most Reliable Full Size Trucks

Most Reliable Full Size Trucks

Each brand works equally hard at telling you they have the most reliable truck you can buy. But which brand actually does?

We researched full-size trucks using trusted resources that derive their data from owner surveys. We used Consumer Reports' data, the 2021 J.D. Power Dependability Study, and CarComplaints.com as our metrics. We then come up with our own letter grade on the model's reliability.

Here is our list of the most reliable full-sized pickup trucks for sale in America.

Check out our top picks for the most reliable trucks in each segment.

Where Data Comes From

Who Provided the Data For This List?

To determine which are the most reliable, we used three trusted sources of information, all of which rely on owner-reported data. Consumer Reports rates vehicles based on a 1-5 scale, with 5 being the most reliable. We used multiple years of Consumer Reports ratings and then averaged them to get one number.

Next, we look at the J.D. Power and Associates vehicle dependability study. This study looks at the number of owner-reported defects in vehicles that have been in service for three years. The J.D. Power study is a brand-wide look at which companies make reliability a focus.

Finally, we look at each model on the CarComplaints website to see if owners report any frequent big-ticket repairs. From all of this data, we then assign a simple letter grade to each model from A to D.

1. Toyota Tundra

Toyota Tundra ReliableToyota has built its global brand on reliability, durability, and quality. You may have noticed that we didn’t say horsepower, payload, or towing capacity. While the rest of the truck makers vie to give you the largest digits on a specification sheet, Toyota focuses on building a truck that won’t break.

The Tundra leads its class in zero ways other than reliability. It has the oldest engine technology, the fewest options for buyers, and although Toyota does offer a TRD version of its Tundra, Toyota doesn’t make anything that rivals the Ram TRX or Ford Raptor. If a Toyota pickup meets your needs, we suggest you seriously consider it if reliability matters to you.

Toyota Tundra Feature

  • #1 truck in quality by a country mile

2. RAM 1500

Ram 1500 ReliableDrive a new Ram 1500, and you will find it offers the best ride in the segment. Based on our testing, this is true across the model lineup and across the range of prices for this truck model. Ram also has adopted the modern tablet-like infotainment system that many shoppers now prefer.

The good news is that Ram’s soft ride does not mean it’s a “soft” truck. Ram offers the highest reliability full-line truck model in America. Ram is also the top brand for reliability when payload, towing, and performance matter to a truck shopper.

RAM 1500 Features

  • TRX trim offers 702 hp and desert-racer capability
  • Best in class comfort
  • Best in class infotainment options
  • Diesel offerings

3. Ford F-150

Ford F-150 ReliableFord’s F-150 line is the broadest in the truck segment, and Ford tops all of the sales charts. Ford didn’t build that volume of sales and its loyal ownership base by making a bad truck. Quite the contrary, Ford trucks have a reputation for being tough on the job site or the campsite.

Ford has gone beyond all other truck makers to offer modern turbocharged and hybrid powertrain offerings. Ford has also been the materials leader in the truck industry, demonstrated by its adoption of aluminum body panels. There are many ways Ford pushes the envelope. This kind of cutting-edge technology sometimes has a downside in reliability, but other times, such as the rust-proof aluminum the company uses, it pays benefits.

4 & 5. GMC Sierra and Chevy Silverado

GMC Sierra ReliableWe were surprised to see the results of the GM truck twins. Although Chevy scores well overall on the J.D. Power brand rankings, its Consumer Reports ratings were less than stellar. Both the Sierra and Silverado 1500 truck models have a ⅕ reliability rating for the 2020, 2019, and 2018 model years.

The brand that pounded our TV screens and radio speakers with the “Like a Rock” reliability advertisement campaign has the lowest scores we could find for reliability. Incredibly, the “Professional Grade” GMC brand does not even score above average on the J.D. Power reliability chart.

Which Is the Most Reliable Full-Size Truck?

Toyota Tundra Most Reliable

Receiving the highest reliability scores from both Consumer Reports and J.D. Power, the Toyota Tundra is also our top pick for the most reliable truck in 2021. Toyota has built its brand on making vehicles that don’t break, and we know from past reporting that the brand also has the customer base that keeps their vehicles the longest.

We were surprised to see how strong the Ram brand’s quality had risen. Ram and other Stellantis brands like Jeep and Dodge already make some of the most exciting products in the auto industry. Now that the company’s focus has turned to quality control, this is the truck to watch in the future.

Note: We didn’t include Nissan in our list because of a lack of data (low sales rate). The data we could find would not have put Nissan on the podium in any case.
