What is the 2005-2015 Toyota Tacoma Brake Master Cylinder Internal Seal Failure Causing Soft Pedal and Reduced Braking?
Multiple 2nd-generation Tacoma owners report a brake pedal that slowly sinks to the floor or feels spongy even after bleeding, often traced to internal bypass failure in the brake master cylinder. Toyota issued service information for diagnosing low or sinking brake pedal concern… Repairs typically run $450-$1,100. Severity: high.
What is the 2005-2011 Toyota Tacoma Secondary Air Injection Pump and Switching Valve Failure on 4.0L V6?
Tacomas with the 1GR-FE 4.0L V6 are known for failures of the secondary air injection system, including the air pump and switching valves. Moisture intrusion and valve sticking can trigger check-engine lights and force the truck into reduced-power or limp mode. Owners frequently… Repairs typically run $1,200-$3,000. Severity: high.
What is the 2005-2006 Toyota Tacoma 1GR-FE 4.0L V6 Head Gasket Failure on Early 2005-2006 Models (Coolant Loss and Cold-Start Misfire)?
The first model years of the 4.0L 1GR-FE V6 used an early head gasket design whose sealing material between the cylinder and the coolant jacket degrades over time, allowing a small coolant leak into a cylinder. The classic signature is a cold-start misfire on cylinder 4 (and some… Repairs typically run $1,500-$3,500. Severity: high.
What is the 2000-2015 Toyota Tacoma Evaporative Emissions Leak Faults from Charcoal Canister, Vent Valve, or Filler Neck Corrosion?
Tacomas in this era commonly develop EVAP system leak faults that trigger a check engine light, often caused by a failing charcoal canister, stuck vent valve, cracked hoses, or a rusted filler neck in salt-belt trucks. Owners usually notice no drivability problem, but the truck w… Repairs typically run $80-$900. Severity: medium.
What is the 2005-2015 Toyota Tacoma Front Wheel Bearing and Hub Wear Causing Humming Noise and ABS Concerns?
Second-generation Tacoma owners frequently report front wheel bearing wear that starts as a low humming or growling noise and can progress to looseness, vibration, and ABS sensor issues because the sensor tone ring is integrated with the hub assembly. Heavier tires, off-road use,… Repairs typically run $350-$1,200. Severity: medium.
What is the 2005-2023 Toyota Tacoma P0430 — Bank 2 Catalyst Efficiency Loss from Aged Converter / Worn Downstream O2 Sensor?
On the Tacoma's V6 engines (4.0L 1GR-FE in 2005-2015 2nd gen, 3.5L 2GR-FKS in 2016+ 3rd gen), Bank 2 is the driver's-side head (cylinders 2-4-6). P0430 sets when the rear (downstream) oxygen sensor voltage begins mirroring the front sensor, meaning the Bank 2 three-way catalytic… Repairs typically run $250-$2,200. Severity: medium.
What is the 2005-2011 Toyota Tacoma Combination Meter / Instrument Cluster Intermittent Failure and Gauge Dropout?
Some second-generation Tacoma owners report intermittent failure of the combination meter, where gauges, warning lamps, or backlighting stop working or behave erratically. The problem can appear as a dead speedometer/tach, flickering cluster, or a cluster that revives after tappi… Repairs typically run $250-$900. Severity: medium.
What is the 2005-2015 Toyota Tacoma 1GR-FE 4.0L V6 Cracked Exhaust Manifold Causing Ticking and Exhaust Leak?
The cast-iron exhaust manifolds on the 4.0L 1GR-FE V6 are prone to cracking from repeated heat cycling, with thin webs near the firewall failing first. This is a distinct mechanical failure from the well-known injector 'Taco Tick' and the secondary-air-injection problem. A cracke… Repairs typically run $400-$1,400. Severity: medium.
What is the 2005-2023 Toyota Tacoma P0011 — Bank 1 Intake Cam Over-Advanced from Failed VVT-i Oil Control Valve?
P0011 on the Tacoma (4.0L 1GR-FE and 3.5L 2GR-FKS) means the Bank 1 intake camshaft is timed more advanced than the ECM commanded. On Toyota's VVT-i system this is overwhelmingly an oil-control-valve (camshaft timing OCV / VVT solenoid) problem, not a mechanical one: the solenoid… Repairs typically run $100-$400. Severity: medium.
What is the 2005-2023 Toyota Tacoma P0302 — Cylinder 2 Misfire from Failed Ignition Coil (2.7L 2TR-FE)?
P0302 flags a detected misfire on cylinder 2. On the 2.7L 2TR-FE four-cylinder Tacoma this is a well-known pattern: the coil-on-plug (COP) ignition coil over cylinder 2 weakens or fails, producing a rough-running, single-cylinder misfire. Worn iridium spark plugs (overdue past th… Repairs typically run $90-$350. Severity: medium.
What is the 2000-2015 Toyota Tacoma Radiator Tank Cracking and Coolant Leaks from Aging Plastic End Tanks?
Across both first- and second-generation Tacomas, owners commonly report coolant leaks from the radiator's plastic end tanks or the tank-to-core crimp seam as the radiator ages. The leak often starts as a pink crust or dampness near the upper tank, then progresses to visible drip… Repairs typically run $250-$900. Severity: medium.
What is the 2005-2015 Toyota Tacoma Spiral Cable / Clock Spring Failure Triggering Airbag Light and Inoperative Steering Wheel Controls?
Second-generation Tacomas commonly develop failure of the steering wheel spiral cable, also called the clock spring. Owners report the airbag warning light turning on along with loss of horn, cruise control, or steering wheel audio controls because the ribbon cable inside the ass… Repairs typically run $250-$700. Severity: medium.
What is the 2005-2023 Toyota Tacoma P0128 — Engine Runs Cold from Stuck-Open Thermostat?
P0128 is one of the most common Tacoma codes and almost always means the engine thermostat is stuck open (or opening too early), so coolant reaches the radiator before the engine hits its target operating temperature within the expected time/airflow window. It is especially frequ… Repairs typically run $120-$400. Severity: low.
What is the 2005-2023 Toyota Tacoma Exhaust Manifold Heat Shield Rattle?
The thin sheet-metal heat shields over the exhaust manifolds and catalytic-converter/exhaust pipe crack around their spot-welds and mounting tabs from years of heat cycling, then buzz or rattle against the exhaust at idle and under light throttle. The noise is often mistaken for… Repairs typically run $20-$250. Severity: low.
What is the 2005-2015 Toyota Tacoma Tailgate Handle and Latch Failure Preventing Tailgate Opening?
A very common Tacoma problem is a broken plastic tailgate handle or stretched/bound latch rods that leave the tailgate stuck shut or unable to latch properly. Owners frequently report the handle feeling loose or snapping internally, especially in cold weather or after repeated us… Repairs typically run $40-$250. Severity: low.
