I had my 2015 isuzu truck towed for service to the isuzu dealership (1463 us-22, mountainside, nj 07092) where I leased it. Even though the truck was brought in due to a problem with the engine that was covered under the truck's warrantee, they forced me to spend over $1000 on a new tire and many other "needed" repairs so the truck could pass federal inspection. Upon picking up the truck, it had no inspection sticker and they slapped one on in less than 5 minutes and could not have inspected the truck. When the...

technician finally came out to my property at 206 tyler road, edison nj 08820, he took the truck for short test drive and upon returning he informed me that the truck had a problem with the steering, sounded loud and it did pull to the right. It did not do that when the truck was towed and serviced. The service manager told me that he would not tow the truck back to the station and that they would fix the problem but I had to drive it back to the isuzu dealership approximately 10 mile. I have lost significant money for my charity someone needs to hold isuzu responsible for faulty repairs and a box truck that passed inspection by isuzu but is not drivable.

Fan clutch has gone out two times already. Isuzu told us in 98 that the fan clutch was defective and a new style was to be built. In feb of 1999 they finally can out with a new model. Time will tell if it was a new model of another lie. We also have a problem with the abs brake warning cable being worn through causing loss of abs system. Manufacturer says it was out of warranty, yet I cant see why a brake line to wear through at 84000 miles on highway roads.
TURBO CHARGER FAILED 3 TIMES.
