Service bulletins for the 2018 Isuzu FTR

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

IB22-N-0012022-11-01. Service bulletin. EXTERIOR LIGHTING:TURN SIGNAL; ELECTRICAL SYSTEM. We 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.
IB17X001C2021-12-07. Service bulletin. POWER TRAIN; STRUCTURE; EQUIPMENT; ENGINE; ELECTRICAL SYSTEM; SERVICE BRAKES. The information in this bulletin is provided to help technicians better understand common vehicle operations that may be incorrectly perceived by customers as a problem. Additionally, diagnostic scan tool connection requirements are outlined for easier technician diagnosis.
IB19X0032019-06-11. Service bulletin. SERVICE BRAKES, AIR; ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL. "SOME CUSTOMERS MAY COMPLAIN ABOUT THE INSTRUMENT PANEL CLUSTER (IPC) AIR PRESSURE GAUGES FREQUENTLY DROPPING INTO THE RED (LOW PRESSURE) ZONE ACCOMPANIED BY AN AUDIBLE ""BUZZER"" WHEN APPLYING THE AIR BRAKES OFTEN, SUCH AS IN STOP AND GO TRAFFIC. WE HAVE DETERMINED THAT THE BRAKE AIR PRESSURE GAUGE RED ZONE BEGINS TO INDICATE LOW AIR PRESSURE UNNECESSARILY EARLY AT 88PSI (612KPA) AS THIS PRESSURE IS SUFFICIENT FOR THE AIR BRAKES TO OPERATE PROPERLY. SIMILARLY, THE BUZZER WILL ALSO SOUND PREMATURELY AT 78PSI (539KPA) AS THAT PRESSURE ALSO IS SUFFICIENT FOR THE AIR BRAKES TO OPERATE PROPERLY. FOR CUSTOMERS WHO EXPERIENCE THIS FREQUENT BUZZER ACTIVATION, ISUZU HAS RELEASED AN UPDATED PIC WITH REVISED (IMPROVED) RED ZONE SCALING AND BUZZER ACTIVATION. THE RED ZONE IN THE UPDATED IPC WILL BEGIN AT 73PSI (501KPA) AND THE BUZZER WILL ACTIVATE AT 66PSI (462KPA). THESE NEW PRESSURE POINTS CONTINUE TO PROVIDE APPROPRIATE AND ADEQUATE WARNING IN CASE OF LOW BRAKE AIR PRESSURE WHILE REDUCING THE UNNECESSARY AUDIBLE WARNING FOR VEHICLES WITH FREQUENT BRAKE APPLICATION, SUCH AS STOP AND GO TRAFFIC. BEFORE REPLACING THE IPC FOR THIS CUSTOMER COMPLAINT, BE SURE TO INSPECT THE AIR BRAKE SYSTEM FOR LEAKS TO ENSURE THERE IS NOT ANOTHER CAUSE FOR THIS COMPLAINT."
