Isuzu Problems

Check Engine Light and Erratic Fuel Gauge Operation

The fuel level sensor may fail resulting in erratic fuel gauge operation and illumination of the Check Engine Light. Replacement of the fuel sender assembly is recommended to correct this concern. A powertrain control module (PCM) software update may be necessary for the updated fuel level sensor to read correctly.

Oil in Spark Plug Tubes May Cause Misfire

On the V-6 engine, oil in the spark plug tubes can cause a misfire. Resealing the tubes as part of replacement of the valve cover gasket and replacing the spark plug wires will commonly repair this issue. On newer models the misfire can result in illumination of the Check Engine Light.

Ticking Type Noise from Engine Valve Train

A ticking noise may be noted from the engine valve train area. This is commonly caused by varnish build up in the hydraulic lash adjusters (HLA). Our technicians tell us that using Mobil 1 synthetic oil has been successful in cleaning the varnish deposits and quieting the lifter noise.

Isuzu 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.

Rear Suspension Rust Concern

Road salt can cause excessive corrosion near the forward mounting bracket for the left or right rear suspension lower link. As a result the bracket can come loose from the frame, impacting vehicle handling and increasing the risk of a crash. Dealers will inspect the affected vehicles. If little or no corrosion is found, the area will be treated with an anti-corrosive compound. If the corrosion has affected the connection between the bracket and the frame a reinforcement bracket will be installed. In very severe cases were a repair is not feasible, Isuzu has a vehicle buy back program in place. All inspections and remedies will be provided free of charge for vehicles that are 10 years old or less. For vehicles older than 10 years, Isuzu will offer a free remedy, but only if the vehicle is presented to an Isuzu service facility dealer within 12 months of when owner notifications were issued, after that time owners will be charged for the repairs.

My dad bought me this car used. I love it but its a money pit. There are always problems. It 's nice on the inside and out I just wish it would work regularly. I will not be buying any Isuzu's in my future.
excelente the only problem i have is vibration from the compressor or ac.
Love my Isuzu. Have taken very good care of it and it has paid me back as an outstanding vehicle.
