Vehicle speed control: cablesReported April 22, 2004 · 72,905 vehicles affected
What is wrong
On certain sport utility vehicles, the accelerator cable can stick so that the engine speed will not immediately decrease upon release of the accelerator pedal.
Risk
This can cause the accelerator throttle cable to delay RPM and vehicle speed reduction for several seconds after the accelerator pedal is released, which in turn, can lead to a crash.
Remedy
Dealers will replace the throttle cable rubber boot. Owner notification began on may 24, 2004. Owners should contact isuzu at 1‑800‑255‑6727.

Recall number 04V199000 · Recall details

Engine and engine cooling: engineReported July 19, 1994 · 122,297 vehicles affected
What is wrong
Constant expansion and contraction of the cylinder head causes the camshaft seal end plug can become dislodged from the cylinder head. This allows oil to leak from the camshaft.
Risk
This can cause engine damage and possible engine fire from oil leaking onto the hot exhaust system.
Remedy
Dealers will install camshaft end seal plug retainer plates.

22 years ago, on feb. 22, 1995 I was driving down silverado canyon rd., which is a very curvy 2 lane road. After a curve I saw 2 cars driving towards me, one passing the other, coming towards me in my lane. I did the only thing I could and moved ~5-7 feet towards the right and flipped over in a counter-clockwise direction. My truck did not have takata airbags (so they told me) but my airbags did not deploy. When I told this to the isuzu spokesperson (2-3 yrs later) he told me that no car's airbags deploy in rollovers because they are not programmed to do so. When I asked why he said that in studies that were done there wasn't any increase in survival in rollovers either with or without deployment of airbags. Can you imagine how I felt. What about the people who do survive? What about me and everyone else in a left handed (counterclockwise) roll. I know because I was in a clockwise roll too and my head stayed straight up and I survived better. In a left roll the driver's head hits the window and they often don't survive. If they do they will have a severe traumatic brain injury and are usually disabled for the rest of their lives. I was in a coma for two weeks and spent two years in neurorehabilitation. I wish I was able to write this to you much sooner but please when the new airbags come in, make sure they deploy in rollovers too. I hope this letter makes up for the people who died in rollovers in the past twenty years. You see I'm a medical doctor who hopes to see some good come out of my surviving that terrible car accident. Even my insurance, state farm said I was in a single car accident when I saw white and red paint on the left side of my green isuzu trooper. I wish I could have written this sooner but I have many long term maladies that caused me to keep forgetting. Maybe god reminded me to write when the takata recall was going on. They're in millions of car

Tl*the contact owns a 1994 isuzu trooper. The contact stated that the throttle cables feel like the cruise control is always active. In addition, the rpms are constantly idling. There has also been an oil leak; however, the failure was unable to be duplicated. Oil leaked onto the steer plate and coated the entire exhaust system and the components of the engine. He found two recalls that listed the exact failure he was experiencing; however, the manufacturer stated that his VIN was not included in the federal safety agency campaign id numbers 04v199000 (vehicle speed control:cables) and 04v132000 (equipment:other:labels). The failure mileage was 139,000 and current mileage was 139,600.

Power steering hose started have massive leak all of a sudden, and it was replaced the following morning. The power steering fluid had sprayed all over everything under the hood, which included soaking the alternator, which in turn made the alternator start to surge at time, causing the transmission to go in to back up mode, and would not downshift on its own after coming to stop. Also every warning light on the dash board was light up, check engine, battery, o2, auto cruise, low fuel, and check trans. Which was odd cause I had full tank of gas, the battery was showing to be with in range on the voltage gauge, the cruise control was off......and the truck was not doing anything strange, drove fine.

Dec. 26, 2005 my husband went to work at 3:00pm in the afternoon. On dec 27,2005 he came home at 3:30 am in the morning, he got in the shower and when he got out our dog started to bark, so he looked out the window into the driveway when he heard a pop. So he looked again and flames started to come out of the passenger front fender. He yelled, I ran out there and he was using the hose I called 911 and we were trying to pop the hood finally right before the fire department got here my husband put the fire out. The firemen opened the hood and then they opened the drivers door and then another fire started in the drivers floorboard coming throughout the firewall. They put that out. They asked if we were driving it but it had been turned off for at least 30 to 40 minutes. The truck was parked next to our house under a car port with both of our kids in the house and at with cars in front of it. The truck was running so good didn't have any problems. I read that there was a recall that's similar which is 94v132000 but isuzu said it wasn't the same so it was my problem. We only have liability insurance. There is nothing left inside the engine compartment besides the main engine. Everything else was burned and fell out.

Was just informed about the value of reporting this. In 1997, under warranty-I showed a line in the frame to a isuzu dealer/mechanic who failed to identify this as a crack in the frame. Since then, the crack has circumvented most of the f-l frame, where the power steering pump is attached. Isuzu corporate refused to correct this or to offer a solution to ensure my safety. In addition, I reported the transmission slipping, jerking into gear and the dealer failed to diagnose the transmission problem, after the warranty expired, the trans failed and I had to have it rebuilt.
