2015 Toyota Tacoma has Four Recalls that Include  Incorrectly Installed Accessories and Mislabeled Stickers

As per the National Highway Traffic Safety Administration (NHTSA), two of the 2015 Toyota Tacoma’s four recalls are for incorrectly installed vehicle accessories like running boards and hood scoops. Improperly tightened fasteners may cause vehicle accessories to become loose and even fall off while driving and become a serious road hazard.

The potential problem affects accessories installed by Southeast Toyota dealers on certain 2011-2016 Tacoma trucks equipped with running boards and/or hood scoops. Toyota is rectifying the issue by inspecting and tightening affected fasteners.

Incorrect Tire and Load Labels Could Potentially Lead to Vehicle Damage

The additional two recalls are for mislabeled stickers. Some 2015 Tacomas may have incorrect load carrying capacity modification labels. This lot also fails to follow federal motor vehicle safety standards. If not rectified, owners might overload their trucks and cause damage to the suspension.

The other sticker recall is for incorrect tire placard information on 2015 Tacomas equipped with TRD accessories. Since 2015 was the first year for the TRD trim, sticker information was not updated.

The trucks equipped with TRD Pro accessory tires and wheels are meatier than the stock ones. But the tire placard sticker still has the stock-tire inflation information. This can result in improper inflation of tires, and an increased risk of a crash. Toyota is sending affected owners a revised tire placard.

One Open NHTSA Investigation Follows Many Complaints of Non-deployment of Airbags in a Crash

The 2015 Toyota Tacoma has one open NHTSA investigation launched in 2019 over the non-deployment of airbags. The investigation has determined that faulty airbag sensors may prevent deployment of the required airbags and other safety restraints during a crash.

Electrical overstress of a component that monitors signals from crash sensors is suspected to be the cause of the airbag deployment problem in the 2015 Tacomas. There is still no concrete idea on what exactly causes the overstress.

2015 Tacoma Owners Complain of Unintended Acceleration, Poor Finish, and Rodent Menace

The 2015 Toyota Tacoma currently has just under 70 consumer complaints registered with the NHTSA. Many owners report experiencing involuntary acceleration. This is mostly seen with trucks equipped with automatic transmissions. Even with brakes applied in Drive, the RPM suddenly increases and the vehicle plunges forward.

There have also been reported instances of limping when on full throttle. This is because of faulty gas pedal sensors and electronic control units. There are a total of nine complaints on malfunctioning brakes that have been traced back to faulty brake actuators and master cylinders.

A fair bunch of 2015 Tacoma owners are not happy with the fit-and-finish levels. The majority of these issues are water seeping into the cabin from the front windshield because of wiper blade cowls getting loose over time. This causes water to soak the cabin air filter and also drip onto the wiring harness.

Rodent menace is another issue that plagues many 2015 Tacoma owners. Toyota’s plan on going green with soy-based wire insulation is the reason. Also, the usage of rice husks for interior trimming has made it a treat for rodents.

Despite Some Problems, the 2015 Toyota Tacoma is a Capable Pickup Truck with Impressive Reliability Ratings

Toyota Tacoma is an off-road-ready compact pickup with a good track run for reliability. Just four recalls for the 2015 Tacoma that sold close to 180,000 units is a testimony of Toyota’s reliability quotient.

The most serious problems with the 2015 Tacoma are over an issue with non-deployment of airbags in a crash. However, the issue is currently being investigated to find a remedy.

All other issues are easy to detect and cheaper on the wallet. Most complaints are being catered to and only a fraction of the 2015 Tacomas have any sort of issues. The 2015 Toyota Tacoma makes for a great used truck, but make sure to check for transmission issues and avoid trucks with over 150,000 miles on the odometer.

Media player electronic glitches with 2015 Tacoma
The only issues I have had with it is the central media player occasionally freezing up and pausing the music for a few minutes before it resets itself and goes back to normal. Might be an internal wiring issue and I haven't checked to see if it is a common problem. Also the gas mileage is not great but that is expected. I usually average around 14 mpg but I live in a rural area.

Transmission went out and engine lacks power.
Poor build quality including accessories and trim. Driver window switch panel broke within 3 years. Needed new transmission right before 60k warranty was up. Cheap plastic bed and 0-60 is so sluggish that it is pointless to even suggest the truck can tow anything.

Toyota Tacoma turning radius needs help.
The biggest problem with this vehicle is the turning radius is horrible as I can never turn into a stall that is tight on both sides. It will not work. I have to back in and out several times before I get my alignment correct.

Awful experience with mechanical issues.
This is my second Tacoma and this one since day one has had sensor issues, rear camera is constantly being disabled and the dealership never wanted to fix it and to top it off it eats thru gas like crazy.

It whistles a lot when I go fast down the highway and it is extremely annoying.
Doors whistles in wind. Doors do not automatically lock when put in drive. No mileage until empty number shown in car. Not accurate temperature reading for outside.
