The 2009 Toyota Tacoma has 5 recalls, the most serious being a fire risk from aftermarket seat heaters and a separate fire risk from rear leaf springs that can fracture and puncture the fuel tank.
The seat heater issue applies to vehicles equipped with aftermarket heated seats installed through Southeast Toyota Distributors: if the copper heating element is damaged, it can short circuit and start a fire. The leaf spring issue affects Pre-Runner and 4x4 models, where a rear leaf spring can crack from stress or corrosion, swing down, and pierce the fuel tank below it.
Two recalls address the driver's airbag. Steering wheel vibration over time can wear out the spiral cable assembly that carries electrical current to the airbag module, and a similar problem affects the flexible flat cable inside the steering column. In either case, the electrical connection to the driver's airbag can fail and leave the bag unable to deploy in a crash. Prior repair attempts did not fully resolve both of these issues, which is why two separate campaigns exist.
There is also a seatbelt concern specific to Access Cab models. Repeatedly slamming the rear access doors can gradually loosen the screws that anchor the front seatbelt pretensioner to its retractor. If the pretensioner detaches entirely, it cannot tighten the belt during a crash, reducing the restraint system's ability to hold an occupant in a severe impact.
