2018 Toyota Tundra Reliability Report

Owners of the 2018 Toyota Tundra frequently report issues with the factory trailer brake controller and the pre-collision warning system. Complaints about the trailer brake controller include failures to recognize the trailer braking system and difficulties setting the gain, with some owners noting that the problem is only detectable when a trailer or simulator is attached. The pre-collision system is often described as malfunctioning, with sensors warning of inoperability, or the system engaging unnecessarily, such as initiating emergency braking without obstacles present. These issues are reported even with low mileage, some as early as 300 to 1,000 miles, and can lead to potential safety risks like near-collisions or unexpected braking. Buyers should be aware that these problems may require dealership intervention and that some fixes, like replacing the trailer brake controller, may not be straightforward.

Owners of the 2018 Toyota Tundra frequently report issues with the vehicle's speed control system, specifically related to the Dynamic Radar-Controlled Cruise Control and Pre-Collision System (PCS). Common symptoms include the cruise control disengaging unexpectedly, the PCS warning light illuminating, and the vehicle braking or accelerating without driver input, sometimes in the absence of obstacles. These issues often occur at various speeds and in different driving conditions, with some reports noting incidents as early as 1,500 miles. Safety implications are highlighted by multiple owners who describe sudden braking or acceleration that could lead to potential rear-end collisions. Buyers considering this model should be aware of these reported malfunctions and their potential impact on driving safety.

Owners of the 2018 Toyota Tundra frequently report issues with the vehicle's pre-collision system (PCS), which can activate independently without a vehicle in front or illuminate warning lights indicating a malfunction. Complaints indicate that these issues occur at various speeds, with some owners noting the PCS warning light illuminates more often in colder temperatures, below 40°F. The reported mileage for these issues ranges from approximately 3,000 to 7,800 miles. Additionally, some owners mention that despite warning indicators, the system fails to function as intended, which could have safety implications, though no crashes or loss of control are explicitly reported. This information is essential for used car buyers to consider potential electronic stability control issues in their purchase decision.

Owners of the 2018 Toyota Tundra frequently report engine-related issues involving oil leaks and wiring damage. Multiple complaints describe cam tower oil leaks, with oil potentially dripping onto the exhaust, posing a fire risk; these issues are noted at mileages as low as 35,000 and as high as 66,000. Additionally, some owners mention rodent damage to engine wires, possibly due to materials used in the vehicle, leading to safety risks. Another issue involves starting difficulties accompanied by misfire codes and disabled trailer brakes and pre-collision sensors. Used car buyers should be aware of these potential safety implications, particularly concerning oil leaks and fire hazards.

Owners of the 2018 Toyota Tundra frequently report issues with the airbag system, including malfunctions indicated by dashboard warnings such as "SRS Airbag System Malfunction." Two complaints involve crashes where airbags did not deploy, resulting in four injuries. One report highlights a head-on collision at approximately 65 mph where airbags failed to activate, and another describes a rear-end collision with subsequent airbag system warnings. Complaints also mention difficulties with addressing recalls related to federal safety standards for occupant crash and side impact protection. The issues are reported at various mileages, with one specific case noted at around 96,000 miles. These reports suggest potential safety implications, particularly regarding airbag deployment in collisions.

Owners of the 2018 Toyota Tundra report several steering-related issues, with common symptoms including squeaking or thumping noises from the steering column and a potential for complete steering loss. Complaints frequently mention the need for steering column or rack and pinion replacements, with some issues arising around 50,000 miles. Multiple owners describe situations where steering components fail, leading to a loss of vehicle control, which poses significant safety risks. For potential buyers, it is notable that some of these issues are similar to those covered in a specific recall, though not all vehicles are included in this recall, and repairs may not be covered under warranty.

Owners of the 2018 Toyota Tundra report issues primarily related to the power train, with specific complaints of transmission problems and emissions control components. One owner describes a serious incident where the vehicle unexpectedly started in gear during inspection, leading to a crash and injury when the left front door closed on them. Another owner notes that the truck fails to accelerate beyond 60 mph, with further pressing of the accelerator causing the vehicle to decelerate, accompanied by a persistent service light for two weeks prior. These issues highlight potential safety concerns, particularly in the case of unintended vehicle movement and impaired acceleration, which may affect vehicle performance and safety.
