Water intrusion is the dominant complaint. Rear quarter duct vents behind the back seats leak through faulty gaskets, allowing water to pool under the carpet where mold thrives. One owner reported his wife developed a fungal lung infection after riding in the truck. The third brake light on top of the cab leaks around its seal during car washes and rain. Roof panels leak where plastic is welded to both sides of the cab—water runs inside along the roof line and eventually reaches the carpet.
Hood issues are common and safety-critical. The latch corrodes and fails to fully close, leaving the hood ajar with only a secondary spring latch holding it. The spring is weak and owners have reported hoods popping open while driving at highway speed. At least one owner bought an aftermarket latch to replace the factory unit. Separate from the latch, some owners report the hood flexes and shakes at highway speed, attributed to faulty adhesive bonding the sheet metal to the frame.
Paint clear coat delaminates across the hood and roof, exposing basecoat and showing heavy oxidation. The defect appears systemic to 2015–2017 model years regardless of color. Toyota has not issued a recall for magnetic grey paint, and some affected owners were denied goodwill repairs despite Toyota's acknowledgment of the defect in other vehicles.
Minor issues include a passenger door that unlatches in cold weather and windows that rattle loudly when rolled down partially. One sunroof spontaneously exploded at highway speed with no prior damage or impact.
Failure modes owners describe
Rear quarter duct vent leaks and water intrusion
Water leaks through faulty gaskets on vents behind rear seats, allowing moisture to accumulate under carpet and in the cab. Owners report musty odors, wet carpeting, and mold growth on the passenger and driver sides. One owner's wife developed a fungal lung infection after exposure to mold in the vehicle. The vents have poor gasket seals and require bed removal to replace.
When: Reported at various mileages; one case at 80,000 miles
Symptoms owners cite: Musty odor from interior; Wet carpet and floor mats on passenger side; Visible mold and slimy water under carpet; Mold growth on back seats
Repairs/costs cited: Owner sealed vents from inside with silicone as temporary fix. Professional repair requires bed removal. Dealership declined help; Toyota corporate and insurance claims filed.
Recalls/TSBs owners mention: Toyota corporate reported to but did not provide assistance. Owner groups (Tacoma Owners Group, Tacoma World) report numerous other affected owners with no Toyota support. TSB 0055-18 mentioned in one complaint.
Hood latch failure and corrosion
Hood latch fails to fully close and lock, leaving hood ajar about half an inch. Dashboard warning light indicates latch malfunction. Secondary safety latch prevents hood from opening fully but spring is weak and corroded. Dealership technician confirmed seeing this often and sprayed solvent to address corrosion around spring, but provided no lasting repair.
When: At approximately 75,000 miles in one case
Symptoms owners cite: Hood will not fully close or lock; Hood remains open approximately 0.5 inch; Dashboard warning light illuminates; Hood pops open while driving; Corrosion and rust visible on latch spring; Secondary latch must hold hood closed
Repairs/costs cited: Dealership sprayed solvent to address corrosion but did not complete repair. Owner replaced with aftermarket latch to resolve. Another owner tied hood closed with bungee cord as temporary fix.
Recalls/TSBs owners mention: Google search shows numerous reports by other 2016 owners with the same problem. Dealership technician acknowledged seeing this issue often.
Sunroof spontaneous glass failure
Sunroof glass suddenly exploded while vehicle traveling at 60 mph on interstate with no prior damage, impact, or environmental cause. Owner had opened sunshade minutes before failure but glass was fully closed at time of incident. No foreign objects struck vehicle, no overpass involvement, weather was clear at 60 degrees.
When: November 6, 2019
Symptoms owners cite: Loud bang from sunroof; Glass exploded into cab; Broken glass rained down on driver; Jagged edges of glass protruded outward
Third brake light (rear cargo light) water leaks
Water leaks through broken or improperly sealed third brake light on top of cab. Water drips through ceiling into rear cab and stains headliner. Multiple forum posts indicate this is a common issue among 2016 Tacoma owners.
Symptoms owners cite: Water drips through ceiling; Water enters during car wash; Staining on headliner; Water accumulation in rear cab area
Recalls/TSBs owners mention: TSB 0055-18 exists for this issue. Dealership stated they could not help despite knowing of TSB.
Paint clear coat failure and delamination
Clear coat peels, oxidizes, and delaminates from hood, roof, and sides exposing basecoat. Defect appears as manufacturing issue across 2015–2017 Tacomas in multiple paint colors including white and magnetic grey. Problem reported as widespread and progressive.
When: Clear coat began peeling in 2022 and progressively worsened
Symptoms owners cite: Clear coat peeling; Oxidation visible; Exposed basecoat in large sections; Complete delamination on hood and roof; Paint fading and deterioration; Paint and sarro (scale/buildup) visible
Recalls/TSBs owners mention: Toyota Customer Care confirmed affected VINs are not included in Customer Support Program 23TE08 and denied goodwill repair authorization despite acknowledging defect in other vehicles. Manufacturer was notified but declined assistance in other cases.
Roof panel water leaks at plastic welding
Water leaks through plastic welding on both sides of roof where it meets the cab. Water runs along inner roof sides and drops between metal and plastic cover at front lateral bars, eventually dripping onto carpet.
Symptoms owners cite: Water leaks by plastic welding on roof sides; Water runs along inner roof; Water drips between metal and plastic cover; Water reaches carpet
Hood flexing and shaking at highway speed
Hood flexes and shakes at highway speeds due to faulty adhesive bonding sheet metal to hood frame. Causes noise and vibration during driving.
Symptoms owners cite: Hood flexes at highway speeds; Hood shakes at highway speeds; Noise from hood area
Passenger door unlatching while driving
Passenger side door comes unlatched during driving. Cold weather causes door latch-handle to freeze and fail to complete latching, creating safety hazard when passenger puts weight on door.
Symptoms owners cite: Door comes unlatched while driving; Door handle freezes in cold weather; Latch fails to complete; Door opens while vehicle in motion
Window rattle when partially rolled down
Driver and passenger windows rattle loudly when rolled down 0.5 to 3 inches, creating persistent noise.
Symptoms owners cite: Loud rattling when window rolled down 0.5 to 3 inches; Annoying noise from windows
