With a Top Safety Pick award from the Insurance Institute for Highway Safety, four-stars overall from the National Highway Traffic Safety Administration, one recall on file and just 48 complaints, the 2020 Toyota Tacoma is the most popular non-full-size truck in the US for good reason.

  • The 2020 Toyota Tacoma has been included in just one recall thus far, for failing low-pressure fuel pumps.
  • A handful of complaints have been registered for fidgety brakes, so make sure to run a thorough test drive.
  • Various electrical problems likely point to rodents chewing through the soy-based wire coating.
  • The Tacoma is famously reliable, commanding a loyal following and standing as the best-selling mid-size truck in the US.
  • The Tacoma’s four-star crash test rating with the NHTSA is comprised of a five-star side rating, four stars for rollover, and four stars for frontal impact.

The 2020 Tacoma Was Included in a Massive Recall for Failing Fuel Pumps

Over one and a half million Toyotas were recalled in late 2020 over an issue concerning the low pressure fuel pump failing without warning. The low pressure fuel pump is the one that moves fuel from the tank to the engine, whereas the high pressure pump distributes the fuel into the combustion system.

The symptoms are about the same whether it’s the low pressure or high pressure fuel pump going on the fritz. You’re not getting any gas into the cylinders, so you’re going to get sputtering, stalling, and loss of locomotive power. At the least, that’s an inconvenience. At the worst, it’s an accident waiting to happen.

The recall covered dozens of Toyota makes and models, including 2017-2020 model Tacomas. The recall seems to have done its job, as fuel system complaints are scarce, but you’ll want to check the VIN of any used Toyota before you hand over any money.

If left unaddressed, failing fuel pumps may lead to long term damage. Running your engine with insufficient fuel distribution can result in debris making its way through the system and causing premature wear. So if the previous driver left the recall unchecked, you might want to shop around.

Fidgety Braking Has Been Reported in Small Numbers

A handful of drivers have reported a random assortment of braking issues in the 2020 Tacoma. One driver reports that the brakes locked up after they came to a stop, others report that the power assist may go out, forcing them to really lean into the pedal to bring the truck to a halt.

There are just eight complaints on file in total, which isn’t too many, but this is the biggest category for NHTSA complaints not related to the above-mentioned fuel pump recall. With only 48 complaints on file in total, 8 reports will be more than enough to qualify this as a leading issue.

Given that these braking issues are so varied, there’s no way of diagnosing a single root cause based only on the data available. That’s the catch-22 of a problem with a low rate of incidence: it’s unlikely to ever happen to you, but if it does, there’s not a lot of information to go on for how you should handle it.

Your best bet here is to simply run a thorough test drive before buying a used Tacoma. See how the brakes handle when you slow to a stop, see how they handle at a sudden halt, see how they handle on inclines and at various speeds. If you can’t solve the problem, you can at least avoid it.

Assortment of Electrical Glitches May Owe to Soy-Based Wire Coating

We’re seeing this a lot these days: a whole range of electrical issues are reported, everything from ignition delays to overheating phone chargers. The complaints are all over the place, with the only thing they have in common being that all of these problems are electrical.

When this occurs, it usually turns out to be the same thing in a Toyota as it is in a Honda, a Ford, a Chevrolet, or anything else: rats and mice are chewing through the soy-based coating used to protect and insulate the vehicle’s wiring.

Soy is cheap and easier on the environment than plastics, so as soon as someone figured out how to make a wire coating out of the stuff, automakers jumped on the opportunity and never looked back. Unfortunately, this makes your vehicle’s wiring delicious to rodents.

The best way to handle this issue is to test all of the electrical features when you take the Tacoma for a test drive, and, if you live in an area where pests are a concern, invest in a bottle of spray repellent. You can find this stuff at your local auto parts store, so pick some up next time you stop by.

Few Issues and Excellent Crash Test Ratings Make the 2020 Tacoma an Easy Pick

Your biggest concern with a Tacoma is going to be the previous owner. Some drivers like to buy compact and mid-size trucks and then drive them like full-size trucks, hauling larger loads than the truck is built to handle and taking years off the truck’s powertrain.

So, while the 2020 Tacoma comes with the highest possible recommendation, test drive and inspection are more important than usual. Feel the truck out, see how it performs on inclines, how it accelerates, and keep an ear open for any clunking, clanking, chugging and clicking.

If you can find a Tacoma in excellent shape, you might just have a mid-size truck that lasts you decades, just make sure you take some time to kick the tires.

Incorrect diagnose
I bought a used 2017 toyota tacoma with only 21600 miles on it (because he did not like how he had to get in the drivers seat?) and i bought it in June 2022 and since then have put about 700.00 miles on it and when not used leave it in my garage. Last week i was driving and it was running perfect. I came to traffic light and stop and when it turned green i pushed the gas paddle and the vehicle would barely move and the check engine light came on and i was lucky to be able to roll into a parking lot. A friend came with his code scanner and he said cylinder 2 and 5 are misfiring. I had it towed to the dealer my brother bought it from and from then on it was a nightmare. First he said it was a bad ignition coil and said he replace it and it was running fine. Twenty minutes later I get a call saying it could be the wiring harness. Then i get a call asking if i might have put diesel fuel in it. No I did not and then i heard nothing back so i took a ride to the shop to find out what is wrong. I talked to the mechanic and ask what is wrong with my truck and he said i hate to give you bad news but one of your valves is no good. He said just for the parts it was 7000.00. I told him I was calling toyota USA and talking to someone because a toyota with only 22000 miles on it should not have this failure. He said he would put it back together in park it in their parking lot and they would not be responsible if anything happens to it. Oh by the way I guess he was talking engineer at toyota and that is what they came up with. So the next day i get another call and they now said it that all six fuel injectors needed to be replace for $5020.00 and they said those fail because there might be contaminated fuel in my gas tank??? They also said they should empty the tank clean it and clean the fuel lines for another 1200.00 dollars. So i arranged to have my truck towed to another repair shop (and had to pay the tow charge) that was highly recommended to me. But before i could leave I had to pay 1030.00 dollars to get my key FOB. 1030.00 and my truck when i started itso i could move so the tow truck could get at it sounded awful. Like it was going to stall. When it was brought to them even though i could not drive it the motor still started and ran like new. The other garage had it for four hours and called me and said your fuel pump is no good. You have to bring it to a toyota dealer and my vin number showed my truck was included in the recall. I looked for recalls on my truck and there were none. Yet the mechanic who called a guy he knew at another toyota repair place asked for my VIN number and i am able to get it replaced for NOTHING. I just have to have it towed back to a toyota repair because they are the ones that have to replace it. Well i can tell you i will not bring it back to the toyota dealer where they are so incompetent. I will pay to have it towed to the dealer my mechanic talked to in avon ct. I was told the mechanic that worked on my truck had 35 years working at the toyota shop. And he also talked to a engineer at toyota USA and neither of them thought to check the fuel pump???? I will be glad to get my truck running again and then i am getting my money back from those idiots at stephen toyota.. If i had let them replace the 6 fuel injectors and clean the gas tank out as they suggested my truck still would not have been fixed. Stay away from the dealer repair shop

Avoid this truck!
I don’t understand why Toyota is selling a car that dealerships don’t know how to repair. The Bluetooth mic went out within three days of me purchasing the truck with only 9 miles on it. I took it into the local dealership in Saint Albans, West Virginia and I knew more about the car than they did. I would suggest avoiding purchasing this car until Toyota has trained people to fix it or they do a overhaul of this new computer system. This car is junk looks beautiful but it stalls, it’s sluggish and hard to handle. Make sure you give yourself plenty of time when you are pulling out because you’re going to need it. I don’t know maybe I got a turd but my, 2015 Toyota sienna minivan had a ton more power and the same v6 engine. I think the transmissions in these things are junk. I’ve only had it three weeks and I am contacting a lawyer in 28 minutes just as soon as their office opens.

Stop vibration and squeaks.
My 2020 Tacoma SX vibrates at low speeds. I have had it in twice. It only has 5,400 miles on it. They said the rear axle flange was out of round & had it for 8 days. It still vibrates under 45. It also squeaks. They power washed the springs and said it was from dust them. ?? It started squeaking again shortly after that. I never had these problems with my 2018 or my Ranger I drove for 14 years. I'm tired of wasting my time at the dealership. I think it may be the tires, but they said it's possibly a characteristic of this truck!!

Frame Rust
When will Toyota fix the problem with the frame rust. You have had may class action cases because of it.1995-2017 and I'm sure 2018 and 2019 will be added soon.Why won't you fix this problem with the frame. I know I will not buy another one till you do.
