The Isuzu CV SPPM (sections 2.15 and 2.16) provides detailed procedures related to vehicle storage up to and beyond 30 days. Performing these required procedures at the specified intervals will properly maintain vehicles until they are retailed. Failure to follow the procedures outlined may result in repairs and additional costs that could have been avoided. We are providing dealers with this brief overview of the recommended procedures as a reminder to maintain older inventory.

10237146This bulletin outlines the procedures for using the Alpine Exchange Program (the "Exchange Program").

Contact Alpine directly for pricing and payment methods applicable to radio and component repairs not covered under warranty.
10225521We have received reports of the front turn signal lenses cracking on Isuzu vehicles. These lenses are cracking from the effects of being washed with alkaline detergents. Alkaline detergents are typically used in industrial settings and are reactive with the paint, metals, and other materials used to make up the exterior components of Isuzu vehicles. Isuzu recommends that only neutral detergents be used when washing Isuzu vehicles. However, if alkaline detergents are used to wash an Isuzu vehicle, it is crucial that all traces of the detergent are rinsed away with water or wiped off as necessary. Allowing alkaline detergent to dry on the turn signal lenses will cause them to crack. Each Isuzu vehicle is originally equipped with an Owner's Manual that includes guidelines for the proper exterior maintenance of the vehicle. The following guidelines are typical of those found in an Isuzu Owner's Manual concerning the use of detergents on a vehicle's exterior.

10178754Isuzu diesel engines available in the above affected vehicles meet the california air resource board's (carb) optional idling emissions standard of 30 grams per hour of oxides of nitrogen (nox) with no increase in the emission of other regulated pollutants. As a result these vehicles have been approved as "certified clean idle" and are "exempt" from the engine shutdown system (ess) requiremnet pursuant ot section 1956.8 of title 13, california code of regulations. As required by the ess regulation, for "certificed clean idle" vehicles, isuzu has introduced a tamper resistance "certified clean idle" label located on the driver's side door panel. It IS important that this label remain, permanently, on the vehicle to identify it as "certified clean idle." carb requires this label as evidence that, at hte time of manufacture, the engine installed met the applicable emission standards. Should the label be found missing or damged during an inspection, a citation and penalties may be issued. If the vehicle IS operated in california with a damaged or missing clean idle label, isuzu recommends vehicle operators follow the 5 minute ess requirement by manually turning off the engine. Following this ess requiremnet will keep the vehicle operation compliant until a replacement label can be installed. "Clean air idle" labels are printed with a serial number and registered to an individual vin. As a result, a replacemnet label will also include a new serial number which must be registered to the vehicle's vin by the manufacturer. The below information IS provided to assit in acquiring, replacing and registering a replacement label.
10178753This information IS being issued to help dealers identify apotenetial source for fuel contamination. If a customer's complaint leads to the discovery of contaminated fuel, the source of the contamination must be found and repaired. Contaminated fuel may result in many different failures. Some examples of these failures are: plugged fuel filters, poor engine performace, check engine light illumination, fuel system (lines and tank) corrosion (rust), etc... Isuzu's failure investigations have found a common occurance of the fuel filler neck being installed incorrectly. This poor installation will allow unwanted material to enter the fuel tank contaminating the fuel. Use the information below to confirm the fuel filler neck IS installed correctly. If the filler neck installation IS incorrect, use the information below to repair the fuel filler neck. Detailed information regarding fuel filler neck installation can be found in isuzu's body builder guide.
