Following Honda's 1990 Accord, the Acura Vigor was introduced to fill the gap between Acura's Integra and Legend. The Vigor was built with a longer wheelbase; it sported a frameless door glass. The vehicle underwent changes through the years but problems still persist. Here are some of the commonly experienced and reported problems:
Acura Vigor drivers usually experience problems with the car's alarm system-the alarm suddenly goes off. This problem is particularly true for 1992 and 1993 Vigor vehicles whose door lock actuator switch easily get corroded, causing the alarm to go off every time the door is unlocked and opened. Drivers usually permanently disable the alarm by opening the hood and finding the little switch that tells if the hood is closed. Bending the alarm system will cause it to permanently think that the hood is open. This would cause the alarm system not to go off even if you lock the doors.
A common problem with the Acura DSP system is that the radio display fades in and out. The problem is likely a bad solder joint in the circuit that connects and powers the display. This issue led to the unit to be covered with an exchange program with Panasonic and Acura.
The Vigor was originally equipped with an R-12 refrigerant that is very expensive. Problems with the conditioning system thus prove to be too costly for most drivers. Many drivers eventually decide to convert to the R-134A refrigerant, which is less costly to maintain.
Aside from the price of maintaining the system, there are blower problems especially with the 1992 Vigor. Over time, the model's blower would operate only on higher speeds and would make a whistling sound. This problem is usually caused by a blown power transistor; there is likely a bad commutator ring in the blower motor.
Reports of failures in engine start-ups are also common. This is usually caused by a bad coolant temperature sensor. A fault sensor fails to properly determine the status of engine and could wrongly report a "cold engine" to the ECU, leading the ECU to dump fuel through the injectors and the engine to flood.
