The Toyota Tacoma is all-around an amazing off-roading vehicle. That doesn’t mean it’s any good on regular roads. Tacoma models have their fair share of issues. The 2018 Toyota Tacoma is a perfect example of a Taco that drivers didn’t love. According to Consumer Reports, the 2018 model has the worst overall reliability score from consumers in the last five years.

Plenty of issues plague the 2018 Toyota Tacoma. Its main problem area is its transmission. The 2018 Tacoma received a 3/5 score for transmission reliability. Buying the 2018 Taco with an automatic transmission is asking for trouble, as this transmission consistently shifts erratically. Transmission slips and unexpected shifts make this one of the worst Tacomas made in recent years.

The transmission is far from the only issue the 2018 Toyota Tacoma has in store for drivers. The 2018 Toyota Tacoma engine is noisy and lacks power. Several other issues have been brought up by consumers, including a fuel pump failure that causes engine stalling.

The Toyota Tundra is the Japanese automaker’s full-size pickup truck. Critics point out the Tundra’s lack of an update or refresh in over a decade. The Tundra also has poor fuel economy, which means drivers will spend the big bucks at the pump.

There are some Toyota Tundra model years that have performed well, but there are some real stinkers among the Tundra lineage as well. The 2012 Toyota Tundra has plenty of issues. It is easily one of the least reliable used Toyota trucks ever sold. The 2012 Tundra scored a 3/5 for engine cooling and 3/5 for drive system issues on Consumer Reports.

One of the main issues with the 2012 Toyota Tundra is an early transmission failure. This transmission failure can cost thousands of dollars to fix. Transmission failures aren’t an easy (or cheap) fix, and there’s no workaround. The 2012 Toyota Tundra also frequently suffers from an air induction pump failure. Between the 2012 Toyota Tundra’s faulty transmission and air induction pump, repairs could run you well over $8,000. Suddenly the affordable full-size pickup truck doesn’t sound so affordable.

The third spot on this list of least reliable used Toyota trucks is another Taco. Since Used Toyota Tacoma models are suddenly experiencing a surge in sales, consumers should pump their brakes before ever deciding to purchase a 2009 model. Old is gold in many cases, but this old Taco is a lot closer to mold than it is to gold.

The 2009 Toyota Tacoma has suspension issues, for starters. Suspension failures have caused a loss of stability in many 2009 Tacoma models, making the truck feel like it was drifting or swaying by itself. Faulty suspension can put a vehicle at risk for dangerous rollovers. The Toyota Tacoma has never provided the smoothest ride, but the 2009 model’s suspension is downright dangerous. It scored a 2/5 for transmission issues and a 2/5 for exhaust issues on Consumer Reports.

The 2009 Toyota Tacoma also had issues with strange radio malfunctions. These malfunctions certainly don’t affect the truck’s overall reliability, but who wants to own a truck with a freaky radio malfunction? Transmission slips, as well as a horrific suspension, make this Toyota Tacoma one of the least reliable used Toyota Trucks that money can buy.
