Owning a 2016 Toyota Tacoma is often a point of pride, as the truck delivered on the brand's promise of durability and capability right out of the gate. This model year represented a significant generational shift, introducing a modern interior and refined performance that quickly made it a favorite among work crews and weekend adventurers. However, even a machine this legendary is not immune to the specific design choices and manufacturing variances that can lead to unexpected problems down the road.
Understanding the 2016 Model Year Context
The 2016 Tacoma was the first of the fifth generation, meaning it shared its underpinnings and components with the 2016 Toyota 4Runner. This platform sharing introduced new technology and comfort features but also tied the fates of these vehicles together regarding certain mechanical gremlins. While generally reliable, this specific year range is now old enough that wear and tear on critical components like the timing chain and suspension bushings are becoming apparent for many drivers.
The Infamous Timing Chain Rattle
Perhaps the most notorious issue plaguing the 2016 Tacoma is the high-pitched rattling noise originating from the engine compartment. This timing chain rattle occurs because the chain guides, designed to keep the chain taut, can wear out prematurely. The sound is often mistaken for a more serious problem like low oil pressure, but it is primarily an annoyance that develops as the vehicle ages and the guides lose their tension.
Identifying and Addressing the Noise
The rattle is most noticeable during cold starts or when the engine is idling at a steady RPM. While Toyota extended the warranty on this specific issue for some models due to its prevalence, many owners find that the repair is not covered as the vehicle ages. The fix involves replacing the plastic chain guides with an updated metal design, a procedure that should be discussed with a trusted mechanic to prevent potential chain stretch or failure if left unaddressed.
Suspension and Steering Concerns
Drivers frequently report issues with the front suspension components, specifically the lower control arm bushings and ball joints. The constant stress of off-road adventures or even pothole-ridden commutes can cause these rubber elements to deteriorate faster than expected. Worn bushings lead to a noticeable clunking sound over uneven terrain and can negatively impact tire wear and handling precision.
Steering Rack Leaks
A more serious and less common complaint involves power steering leaks originating from the steering rack seal. A small leak might seem harmless, but it leads to a gradual loss of fluid, which can result in stiff steering and, in extreme cases, complete power steering failure. Inspecting the area for wetness during routine maintenance checks is crucial for catching this issue before it compromises safety.
Electrical and Infotainment System Glitches
The 2016 model year introduced a more modern touchscreen infotainment system, but this technology is not without its flaws. Some owners experience random system freezes, unresponsive touchscreens, or, more critically, failure of the backup camera display. This camera issue is particularly frustrating as it leaves the driver relying on mirrors alone when reversing, creating a significant safety hazard that often requires a dealer visit to repair.
Fuel System and Oil Dilution
In regions with short trip driving patterns, a condition known as gasoline dilution can occur. This happens when raw fuel seeps past the piston rings and mixes with the engine oil, creating a milky brown substance that reduces the oil's lubricating properties. Regular driving habits that allow the engine to reach full operating temperature are the best preventative measure, and more frequent oil changes may be necessary for drivers who rarely take long trips.
While the 2016 Toyota Tacoma remains a capable truck, prospective buyers should be aware of these specific vulnerabilities. A thorough pre-purchase inspection focusing on the timing chain noise, suspension components, and steering system can mean the difference between a great purchase and a costly headache down the line.
