Isuzu Ascender Problems

Harsh transmission shifting due to failed input speed sensor

The transmission may develop a harsh shift condition with the Check Engine Light on and fault code P0717 stored. This is commonly cased by a failed input speed sensor (ISS), located inside the transmission. The wiring at the sensor may be found damaged. If so, the sharp edges near with ISS wiring should be filed smooth to protect the new speed sensor wiring from damage.

No start due to failed ignition switch

The ignition switch may fail resulting in a no start condition. Replacement of the failed switch is necessary to correct this condition.

Fuel Level Sensor May Fail

The fuel level sensor may fail resulting in erratic reading of the fuel gauge. Sensor replacement is generally required to correct this concern.

Isuzu Ascender Recalls

Headlights & Daytime Running Lights

These vehicles are being recalled because the headlamp driver module (HDM) can overheat and fail. This will cause the headlights and daytime running lights to stop working. Loss of this lighting will affect the ability of the driver to see the road and reduce the vehicle's visibility to oncoming vehicles, both of which increase the risk of a vehicle crash. The remedy for this problem is still under development and not yet available.

Power Door Locks And Windows Do Not Operate

The module that operates the power window and lock switches can allow moisture in, causing corrosion that can lead to a short circuit. This results in window and lock functions not working, and creates a fire risk. Dealers will inspect and replace affected modules free of charge to resolve the concern.

Door Window and Lock Switches May Stop Working

Fluid may enter the driver's door module, causing corrosion that could result in a short circuit in the door module. A short circuit may cause the power door lock and power window switches to function intermittently or become inoperative. The short may also cause overheating, which could melt components of the door module, producing an odor, smoke, or a fire. Dealers will inspect the driver's door module, if it is functioning correctly, a protective coating will be applied. If the module is not functioning correctly, it will be replaced. The GM recall number is 12180.
