The Toyota Tacoma, a stalwart of the midsize pickup truck segment, has been a top-seller for 21 consecutive years, with 274,638 units sold in 2025, a 42.4% increase over the previous year. However, beneath the gleaming sales figures lie a history of issues that have plagued the Tacoma over the years. From structural problems to drivetrain defects, these issues have not only impacted the reliability of the vehicle but have also raised safety concerns. Here's an in-depth look at five of the most significant problems that have affected the Toyota Tacoma.
Frame Rot (1st and 2nd Generations)
One of the most notorious issues in the Tacoma's early history was frame rot. Toyota's initial frames lacked adequate rust protection, leading to cosmetic corrosion and, in some cases, structural damage that made the vehicles unsafe to drive. This problem was so severe that it resulted in a $3.4 billion court settlement in 2016, covering all 2005 to 2010 Tacomas. The settlement provided $15,000 per vehicle for frame replacement, a significant cost for many owners.
The consequences of not addressing this issue were dire, ranging from spare tire mounts separating from the rear-cross member to the loss of control while driving. In extreme cases, corrosion could cause the fuel tank to drop to the ground, potentially bursting into flames. This issue has haunted older Tacomas, with some owners still experiencing frame rot despite the replacement.
Lower Ball Joint Failure (1st Generation)
The first-generation Tacoma had a serious safety defect in its front suspension. A production issue caused the lower ball joint surface to become scratched, which, over time, accelerated wear and led to the joint failing spectacularly, resulting in a loss of steering control. This defect affected 768,379 vehicles, including 2001-2004 model year Tacomas.
Owner complaints were vivid, with some reporting the front wheels detaching from the vehicle while driving at highway speeds. Dealers replaced the front suspension lower ball joints free of charge, but the issue persisted for some owners, with at least one explicitly stating that the recall repair failed on their 2003 Tacoma. This defect also affected the Tundra, Sequoia, and 4Runner of the same era, making certain used Toyota models from this period worth avoiding.
Rear Differential Leak (3rd Generation)
The third-generation Tacoma, introduced in 2016, suffered from a serious drivetrain defect. The new BD20D rear differential carrier had a potential sealing surface contact variation, causing the nuts fastening the differential carrier to the axle housing to become loose. This issue was so severe that it led to a recall covering 227,732 2016-2017 Tacoma vehicles.
If the differential was dry, the repair involved tightening the nuts properly. However, if there was a leak, the gaskets and nuts were replaced. In extreme cases, the entire differential assembly was damaged, requiring Toyota to replace it free of charge. Owners risked potential loss of control problems, which could even lead to a crash, if they hadn't had the differential replaced.
Automatic Transmission Issues (4th Generation)
The fourth-generation Tacoma, with its new turbocharged engine, available hybrids, and platform shared with the Tundra and Sequoia, faced transmission failures even on very low mileage, sometimes under 1,000 miles. This issue resulted in numerous complaints and was officially reported to NHTSA. Toyota issued a technical service bulletin (TSB) in September 2024, acknowledging the problem but stopping short of a full recall.
The issues typically involved the transmission jumping into neutral, being sluggish, or not wanting to shift out of a higher gear. The problem seems to involve components in the transmission becoming stuck in an off position. While the severity and scope of the issue are unclear, it has the potential to cause accidents, and Toyota's treatment of it as a TSB rather than a recall is concerning.
Brake Master Cylinder Failure (3rd Generation)
Brakes are non-negotiable, and on certain 2018-2019 Tacomas, Toyota got them wrong from the factory gates. An improper machining issue at a supplier facility left a master cylinder seal without its correct chamfer, causing an internal fluid leak that reduced front brake performance. This defect was so severe that it led to a recall covering 44,121 vehicles.
Drivers encountered the brake pedal going all the way down to the floor, which could lengthen the distance the truck needed to stop safely, potentially leading to accidents. The average mileage at which problems occurred was alarmingly low, at 6,866 miles for the 2018 Tacoma and 3,336 miles for the 2019 Tacoma. As many as 90% of vehicles are estimated to experience this defect, making it a significant concern for Tacoma owners.
In conclusion, while the Toyota Tacoma has been a top-selling midsize pickup for many years, its history is marred by several significant issues that have impacted its reliability and safety. These problems, ranging from structural defects to drivetrain issues, highlight the importance of thorough quality control and ongoing maintenance to ensure the longevity and safety of the vehicle.
