2021 Toyota Tacoma — Known Issues & Recalls

Your brake pedal sinks all the way to the floor when you press it. Even after having the brakes and master cylinder replaced, the problem returned about a month later. This recurring issue suggests there may be an underlying problem that wasn't fully addressed in the previous repair.

Your truck's right front brake shoes are loose and not properly positioned, and the entire brake assembly has significant rust. The brake lines are leaking fluid. This is a serious safety issue that requires immediate inspection and repair to restore proper braking function.

Your vehicle stops normally when you press the brakes, but after a few seconds it starts moving forward again on its own. The brake pedal sinks further down, the car stops briefly, then creeps forward again — forcing you to use the emergency brake to prevent rolling into traffic. A mechanic diagnosed this as a faulty brake master cylinder. Replacing the master cylinder fixed the problem.

Your Tacoma stalled while driving at highway speeds, with the engine oil warning light flashing and a fuel odor coming from the vehicle. The dealer diagnosed the problem as a defective fuel pump. Replacing the fuel pump should resolve the stalling and odor issues.

Your 2021 Tacoma takes longer than normal to start when it's cold outside, even though no warning light appears. The dealer checked it and said the issue isn't covered under Toyota's fuel pump campaign, and your vehicle's VIN isn't included in any recall for this problem. The issue appeared around 62,000 miles. Diagnosing the cold-start issue may involve testing the fuel pump pressure, fuel injectors, or ignition system components.

When you start your 2021 Toyota Tacoma, you're hearing an abnormal clacking noise from the fuel pump that wasn't there before. The dealer said this sound is normal, but you noticed it during a routine oil change at around 24,000 miles. The fix would involve the dealer inspecting or potentially replacing the fuel pump to determine if the noise is actually a defect or normal operation.

While driving slowly at 10 MPH, you pressed the accelerator and then tried to brake for a left turn, but your truck didn't respond as expected. You pulled into a parking lot safely, and no warning lights appeared on your dashboard. An independent mechanic looked at it, but the diagnosis results weren't clear, and the vehicle wasn't repaired.

Your transmission hunts between gears (usually 5th and 6th) while cruise control is active, sometimes revving near redline before shifting. You have to manually downshift to 4th to regain control, and the transmission shifts more frequently than it would in your manual 6-speed V6 Tacoma. A transmission control module reprogramming or fluid service may be needed to resolve the hunting behavior.

The coolant bypass hose at the rear of your engine (a plastic part connecting the cylinder heads) can fail and leak coolant, causing your engine to overheat. You might notice a small puddle of coolant under your vehicle, but the leak may not be obvious under the hood, so you could suddenly experience engine overheating while driving without warning. A dealership inspection and repair would typically involve replacing the coolant bypass hose assembly with a new one.

Your driver's seat heater stopped working after you noticed a burning smell. When you checked it, you found the electrical connections to the heated seat were discolored and scorched. This suggests an electrical fault caused overheating in that circuit, and the same issue could potentially affect the passenger seat heater.

Your speedometer needle jerks or jumps when driving at 85 mph with cruise control engaged, but the problem goes away when you slow down to 84 mph. This appears to be an intermittent electrical or sensor issue with your speed gauge.

Your AC compressor is leaking refrigerant gas instead of maintaining proper pressure. Your dealer says you need a new compressor, which seems premature for a 4-year-old vehicle. The fix will involve replacing the AC compressor and likely recharging the system with fresh refrigerant.

The complaint was submitted but contains no specific details about what problem the owner is experiencing with their vehicle.

Your vehicle was involved in a car accident, but the airbags failed to deploy when they should have. This is a serious safety concern that needs immediate investigation to determine why the airbag system didn't work as designed.

Your truck has stalled and completely shut off while driving on multiple occasions — once at highway speed (75 mph) with no warning, and twice at low speeds while backing up or driving slowly. The dealership found cylinder misfire codes and engine stall codes, and warning lights appeared each time (master warning, charging system, oil/fluid temperature). Despite documented diagnostic codes at your dealership, the manufacturer's technical review found insufficient evidence of a stalling problem after a short test drive, and did not respond to your lemon law claim within the required timeframe. Diagnosing this will likely require the dealership to perform a full engine diagnostic scan, check the ignition and fuel system components, and possibly replace spark plugs or ignition coils.

Your blind spot monitoring system failed at 117,000 miles and needs a $300 repair. More significantly, a mechanic recommends replacing your power steering lines ($927) and transmission lines ($797) due to severe rusting and corrosion before they leak or break. This is a preventive maintenance recommendation to avoid potential fluid leaks that could affect steering and transmission function.

Your Tacoma's front radar sensor for the forward collision avoidance system is missing its protective back cover, which is causing it to fail. This is a known recall issue affecting this system. Without the cover, the radar may not function properly, potentially reducing the effectiveness of your collision warning and automatic braking features.

Your 2021 Tacoma has developed a coolant leak near the rear of the engine that keeps returning even after topping off the coolant reservoir. The vehicle failed to start with no warning lights, and a dealer diagnosed that both the coolant leak and the starter motor need repair. The dealer confirmed the repairs aren't covered under warranty at 102,000 miles.

Your engine's coolant bypass joint is leaking, which was discovered at 47,800 miles. This can cause your engine to overheat if coolant levels drop too low. The repair will likely involve replacing the leaking bypass joint and refilling the coolant system.

You noticed coolant leaking from the coolant bypass valve when you opened the hood of your parked vehicle at around 50,000 miles. A dealer confirmed the valve needed to be replaced but informed you it wasn't covered under warranty. The repair will likely involve removing and replacing the coolant bypass valve.
