How to read a Isuzu Trooper VIN — every digit explained
Every Isuzu Trooper carries a unique 17-character VIN stamped at the factory. Each position is a code — together they spell out where, when and how your car was built. Here's exactly what every digit means.
- WMI (1–3) — country & manufacturer. 4T1 = Toyota, built in the USA.
- VDS (4–8) — model line, body style, engine & restraint system.
- Check digit (9) — a math check that proves the VIN is genuine.
- Model year (10) — the year it was built. H = 2017.
- Plant (11) — which factory assembled this Trooper.
- Serial (12–17) — the unique sequential production number.
Model-year code (10th digit)
The 10th character is the model year. It cycles through letters and numbers, skipping I, O, Q, U, Z and 0 to avoid confusion:
Where to find your Trooper VIN
- Dashboard — driver's side, visible through the windshield from outside.
- Driver's door jamb — on the manufacturer sticker when you open the door.
- Paperwork — vehicle registration, title and insurance card.
- Engine bay & frame — stamped on the firewall or chassis on many models.

Engine And Engine Cooling 191 Read
I get frequent oil changes in my 99 isuzu trooper and had just gotten one last month. I had at least 2700 miles before my next one. I was driving down the freeway and i saw smoke coming from my hood and all my dash lights came on like a christmas tree. I pulled over and found out that my engine was on fire. I called the fire dept to put it out and got it towed to my house to later find out that the piston had got thrown from the engine because it locked up due to no oil getting to that piston. So now i have to get a new engine which cost about the same as the car. *tr
I bought a 1999 isuzu trooper limited edition 1 year ago this month. Since buying it i have had the starter replaced, the alternator replaced twice, the small block was bad because of a failure with the dipstick to read the correct amount of oil. My son was involved in a mva due to the fact that the vehicle would not stop as the engine decided to race while he was coming to a slow stop. Thank god no one was injured in the accident. The car revs up at an idle at a stop or slowing down position, and now the vehicle is in the garage because the transmission is bad and the alternator went again. The front windshield is not properly sealed and the window fogs up if you don't run the defroster. The draft that comes from the floor on the drivers side is unacceptable. I bought this car with less than 30,000 miles on it and it now has less than 50,000. I really don't understand why a vehicle with this low mileage has so many problems and it is in the shop more than it is out. I expected to have some problems with a used vehicle but not this many and not this costly! I have been reading about many similar problems with this year of trooper and i'm wondering what it's going to take to have the company stand up and take responsibility.*ak
We were driving in my 1998 isuzu trooper with the 3.5 liter engine and about 90,000 miles on a family vacation to montana, as we came to our destination we were in the mountains. The cruise control was being used in our vehicle and was set at approximately 75 mph, the montana speed limit. The vehicle had to downshift to go up the mountain side upon getting to the top of the mountain the vehicle quickly began to make a strange noise. Seconds later there was a loud boom and engine parts went flying everywhere, we had dropped 2 pistons out the bottom of the engine and nearly lost control of the car from such bad damage. We quickly pulled over to see what exactly had happened and noticed that the oil leaking from the bottom of the car had caught fire and we had to quickly extinguish it. We then picked up the engine parts from the highway to not hurt other vehicles. We contacted the local police and they aided us in getting to the nearest dealer 110 miles away. The dealer took over a week to replace the engine block and other components for a cost of over $6,000. The engine block and other damaged parts were disposed of properly. Upon returning home and investigating i found that this incident is very common and has cost many people thousands of dollars. I believe that isuzu is aware of this problem and should fix it or reimburse people who have had these problems. This put my families safety and lives in harm and i think isuzu should be held accountable. *nm
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. *jb
My husband came home from work , turned the truck off came in the house. Got in the shower 30 minutes later when he got out of the shower he heard a pop and flames were coming out of the passenger side tire from under the hood. The whole truck , engine caught on fire. There was no smell or anything to think there was anything wrong if he would have went to sleep it would have caught our house on fire and my husband , two kids and me would probley be dead because thats what the firemen said it was spreading so fast. *jb
Tl*the contact owns a 1992 isuzu trooper. The contact noticed oil leaking onto the intake manifold. He noticed the issue when heavy smoke appeared from the engine while driving approximately 55 mph. The dealer stated that the vin was not included in nhtsa campaign id number 94v132000 (engine and engine cooling:engine). The manufacturer initially stated that the vin was not included in the recall, but later stated that the vehicle had previously been repaired according to the recall. The current mileage was 192,031 and failure mileage was approximately 188,000.
The vehicle's tail pipe separated from the muffler's discharge flange which is turned 90 degrees up, causing the hot ehhaust gases to hit the floor deck on the left side of the vehicle, just behind the back seat. The result was burning the undercoating off, setting fire to the carpet padding and seting fire to a duffel bag containin clothing that was placed over that location. This resulted in flames inside the vehicle, which were put out before any other damage could occur. Looking at newer trooper's isuzu continues to use the same muffler with no heat shield above the flange. In a six mile drive the the dealer with the pipe broken enough, heat was generated to stare the matting smoking again. In my mind this is a serious defect in design that could creates a major fire hazard given the failure rate of exhaust components over time. *ak
Vehicle's tailpipe separated from upturned flange at rear of muffler, causing melting and burning of undercoat beneath vehicle left rear floor, and also caused melting and charring of carpet and vehicle contents stored above that spot on the floor. The separation was caused by rusting.
Vehicle's engine compartment caught on fire.*mr consumer was at a toll both when she noticed smoke coming from the engine compartment. She pull over into the employee parking lot and exited the vehicle with three other occupants. The fire was extinguished by the fire department. There were no injuries. *ph *nlm
The trooper had an oil leak and the engine went on fire. My car is totaled. I have been researching and see a problem with this model and year. Help! I want isuzu to pay for my lose even if i was the second owner or bob ciasulli used cars for selling me this car which had a recall on and put myself and my 5 year old son in danger.
Power Train 82 Read
When the consumer approached a train track, another vehicle began to approach from the other direction. The consumer stopped and shifted from drive to reverse to clear up the road way. The transmission jumped to park and locked preventing the vehicle from moving. A train approached and struck the vehicle. Please provide further information. *jb

The vehicle was shut off in park. After some time the vehicle rolled out of the parking garage and hit a drainage poll. The consumer made an appointment with the dealer for diagnosis and repairs. *ak
Vehicle was parked on slight hill when it popped out of gear. Also, emergency brake failed, causing it to roll down into a tree. Isuzu engineers claimed vehicle passed all specifications, but consumer knew for a fact that it did not hold. Vehicle will only brake at the ten o'clock. Also prior to incident, consumer had complained about transmission noise, and that it was difficult to shift. *ak
Transmission was replaced 3 times due to failure or leakage and this transmission was showing signs of slippage after driving 40 miles on highway. Trooper was being operated on i-895 in baltimore at 50 mph when smoke was seen in rear view mirror. Trooper was pulled to side and son exited vehicle to check engine. Trooper immediately burst into flames resulting in a total loss of vehicle and contents.*ak
The transmission has been shifting rough since the vehicle was purchased new in 1991. The first incident was covered under warranty and some minor repairs/adjustments were made by the dealer. The second incident required more extensive repairs to the transmission and i was required to pay a portion of the repairs since the warranty had expired by some 2-3k miles. Upon the third incident with the drive train, i requested someone from the manufacturer to investigate. They requested that i keep a log for about two weeks of the conditions occurring while driving. After this period, they felt the problem was in the universal joints. These were replaced and the problem still exists. Other complaints in the drive train involve the inability of the cruise control to maintain speed on slight inclines and would suffer a great reduction in speed on a moderate to steep incline. With regards to the fuel injection system, a fuel injector plug exploded while driving at highway speeds and erupted in a fire that self-extingushed. The dealer was informed the replacement part was no longer available even though the vehicle was only 7 years old at the time. I proceeded to an independent mechanic who was able to use a gm part (i found out that the drive train and engine are actually made in whole or in part by gm even though my vehicle is an isuzu). There was a second incident idetical to the first and the repairs were again made. I had the dealer conduct an investigation to determine the cause of this failure. They wer only able to determine that the thermostat was not operating at full capacity, but could not say this was the cause of the injector failures.
Transmission fluid leaking out through the measuring dipstick and over the engine, causing vehicle to catch fire, resulting in explosion and major property damage, prior to recall notice (90v167000). *yc
Consumer drove vehicle into driveway. Then moved transmission into what he thought was park, locked ignition and took key out. When he walked away vehicle rolled backwards, resulting in a crash. Phoned isuzu and was told that they did not install an ignition interlock device. Owner believes this is a necessary safety device. *ak
Transmission repaired 4 times, vehicle caught on fire due to overflow of transmission fluid. *sd
Transmission fluid expulsion resulted in fire. *aw

Tl* the contact owns a 2002 isuzu trooper equipped with bf goodrich mud terrain t/a km2 tires, size: lt265/75r16. While driving between 55-65 mph, three of the tires experienced tread separation. There were momentary vibrations just before the failures. The failures occurred on three occasions. The vehicle was taken to a tire dealer where the front driver side and rear driver and passenger side tires were deemed defective. The tires were replaced. The defective tires were replacement tires with only 12,000 miles on them prior to the failures. The vehicle failure mileage was 49,000 and the tire failure mileage was 12,000. The vin and dot number were not available. *tr
I was driving down the highway doing 60 miles an hour when my "bridgestone tire" separated at the tread and peeled off like a banana and i thought i was going to crash! The tire stayed intact and the bands with no deflation". I am concerned that this tire will be or was a recall. No accident luckily, no injury, luckily because it was on the back passenger. If it was on the front i would of been screwed for i was making a 60 mile an hour curve on the highway with frequent traffic rush hour with a top heavy "isuzu-trooper". This tire needs to be investigated!!!!! Never , at age 46 , seen a tire peel the tread off the radial belt like this like a retread! Must someone die or be hurt before "bridgestone" is held accountable like in the year 2000 when they had multiple deaths and lawsuits? Thank you , please help. *tr
Dealer replaced rear and front tires on two different occasions. First time at 15000 miles, and the second time at 22000 miles. But still having the problem, wearing out prematurely. Bridgestone, dueller hl, size 235/70r16.*ak

Sudden acceleration, causing accident/injury. *ak
Dt: the contact stated 2001 isuzu trooper accelerated while in reverse, then he put the car in drive, it hesitated and surged forward while the brakes were applied. The vehicle left black marks in the driveway, went through the garage cans and through a fence in the backyard. All this time the brakes were being applied. Meanwhile ,the vehicle still had a wide open throttle, and was spinning in the grass. Finally, the contact was able to turn off the ignition. There was damage to the yard and fence. The contact contacted isuzu, and they said it was not suppose to do that. The car sustained $5400.00 worth of damage. No police report was taken. *ak

Motor will rev up when sitting still at a red light and try to lunge forward. I have even had it go 35 miles an hour without my foot even being on the accelerator. I have had my truck to the dealer 3 times now and they keep saying they can not find anything wrong. Unless they can see the vehicle do it they can't fix it. The check engine light does not come on and they say until that happens they don't know what is wrong. Dealer refuses to keep vehicle and drive it until it does it so they can see it. They make it sound like i am making this up. There is a problem and it needs to be fixed. I do not want to be responsible for a accident that i have no control over. The state police says it is illegal to drive a unsafe vehicle on the state highways. I owned a brand new vehicle that is illegal for me to drive on the state highway and isuzu won't do anything about it. I have contacted isuzu corporation as well as been back to the dealership 3 times and it is still doing it.*ak
When at a complete stop vehicle will start to rev. If consumer does not have foot on brakes vehicle will start to move forward. Contacted dealer, and dealer was not willing to do anything.*ak
While driving vehicle stalled. This failure caused a collision. Dealership serviced vehicle numerous times, and replaced the main computer, accelerator motor, and several other components. But, problem recurred.*ak
Unwanted acceleration - the vehicle accelerates spontaneously while driving and contine to accelarate or hold steady speed without depressing the accelerator causing the driver to have to continually depress the brake pedal in order to slow the vehicle. While trying to stop it will continue to rev and then suddenly rev down causing the vehicle to suddenly lurch down because of the pressure on the brake. The vehicle will start at normal rpm's and then surge when the vehicle is put in gear (forward or reverse). It has been to the dealer four times and the dealer cannot identify or repair the problem, twice in july of 2002, once in august of 2002, and most recently in july of 2003. *ak

I contacted isuzu of america customer relations hotline and was "brushed off". My isuzu trooper was in excellent condition prior to the crash and the computer failure was brought to my attention by the isuzu mechanic. The vehicle has not been repaired yet, with the exception of the front suspension. I was told not to drive the vehicle because the pcm is malfunctioning and can cause the transmission to go out of control. In fact, i when in the "drive" mode on the selctor, the computer puts the transmission in "reverse". In order to drive my vehicle, the gear selector has to be in "neutral". There is no "park" gear. The computer went out without warning and told the transmission to go into "reverse" mode. The floor shifter lever did not move and remained in the "drive" mode before, during and after the crash. The "drive" mode is now "reverse". I was told by the isuzu mechanic that this is a common in troopers and rodeos with electronically controlled automatic transmissions and most people are unaware of this problem. I was also told that my ecm is in the "default mode" and sending error signals to my engine and transmission. The mechanic said this is what caused the transmission to randomly shift out of "drive" into "reverse" while travelling at 50-55 mph on the highway. I have information on similar crashes invilving the 1994-1998 isuzu troopers, rodeos, honda passports and acura slxs. Some have resulted in injuries and deaths. How many must die before isuzu takes an interest in this problem. I found that there are many isuzu owners who have had to replace thier ecms at their own expense. There is nothing in the owners manual which warns consumers about the potential problems the ecm could cause, nor is there information on servicing. There is one technical service bulletin referencing automatic transmission failure of troopers and rodeos, but it doesnt provide much information about exactly whic component is affected. Feel free to contact me.
I just exited the hollywood freeway when suddenly without warning the 1991 isuzu trooper caught on fire. I was able to get to the side of the road, and get out.the fire appeared to be underneath the truck with gas or some other liquid pouring out. The passenger side front tire melted and exploded, then there was a second explosion. All the parts of the engine, battery etc. Were in flames. Two fire trucks and police cars were dipatched. It was a very big blaze. The truck has been declared a total loss. Our insurance compnay cannot determine what caused the fire since the damage is so extensive. Please help. I am not sure how to proceed. I'd like to warn other owners of this vehicle and contact isuzu. So far, they have not returned my phone calls.
I bought a 1999 isuzu trooper limited edition 1 year ago this month. Since buying it i have had the starter replaced, the alternator replaced twice, the small block was bad because of a failure with the dipstick to read the correct amount of oil. My son was involved in a mva due to the fact that the vehicle would not stop as the engine decided to race while he was coming to a slow stop. Thank god no one was injured in the accident. The car revs up at an idle at a stop or slowing down position, and now the vehicle is in the garage because the transmission is bad and the alternator went again. The front windshield is not properly sealed and the window fogs up if you don't run the defroster. The draft that comes from the floor on the drivers side is unacceptable. I bought this car with less than 30,000 miles on it and it now has less than 50,000. I really don't understand why a vehicle with this low mileage has so many problems and it is in the shop more than it is out. I expected to have some problems with a used vehicle but not this many and not this costly! I have been reading about many similar problems with this year of trooper and i'm wondering what it's going to take to have the company stand up and take responsibility.*ak

I have had a history (documented) of electrical/transmission problems with my 1991 isuzu trooper. On 11/95, a faulty computer control panel caused my transmission to fail. I had a week left on my powertrain warranty. Took the vehicle to isuzu santa monica. They replaced the computer panel under warranty on 11/95. 15 months later, my transmission was failing again. Same symptoms. This time, i spent $2,000 to have it repaired. Isuzu refused to take responsibility. On 6/12/99, without warning, the engine started smoking and within seconds the entire engine was on fire. The fire dept. Came and put out the fire. Now the truck is completely totaled. I am in the midst of having insurance inspectors determine the cause of fire. I have all of my service records for the vehicle. It was kept in excellent condition.

1(a). After driving at highway speeds (above 60 mph) the abs warning light on the instrument panel nearly always comes on. This has ocurred hundreds of times. 1(b). When driving in slippery snowy conditions, after applying the brakes the abs computer makes a loud buzzing noise that will not stop until the electrical connection to the 4 wheel drive abs component is severed by either removing the negative battery cable from the battery or removing the fuse. This has ocurred many times, but only three times has it caused a loss of control where people were at risk of harm. 2. Under the buzzing condition noted in 1(b) above, the abs braking system seems to fail, with less control because the brakes lock up, and steering becomes impossible. At least three incidents have happened where the vehicle ran into the curb with no apparant damage, greatfully no other vehicles or persons were involved. Each incident 1(b) has happened on weekends or at night after the dealer who services the vehicle is closed. 3. The dealer has found no problems, stating we must bring in the vehicle with the light on or the buzzing occurring in order to locate a problem. I belive there have been recalls on other isuzu models for the same problem, but not for the model or year of our vehicle.

My wife stepped on brake pedal to shift into drive the brake went to the floor, i went out to try it myself & got same result. After opening the hood i noticed master cylinder was at a 45 degree angle to the right, the bolt on the vacuum booster had snapped of which damaged the booster & pedal function. If this had happened during vehicle was in motion it could of had severe consequences. I notified isuzu of america to see if it was covered on our warranty they said no , i asked you don't want to do anything about a defect like this, the answer was still no. I find this disturbing since i am a auto body tech/appraiser and i felt you should be informed of this episode. Any response would be help full thankfully she did not try and drive this car & i was at home to see it i have pictures , dealer has vehicle. Here is the reps name & number john quilan 678-977-1287 . Dealer number attn tom toppan (they have been great) 508-697-3113 . Im not sure hwo this works so i will place it under defective equipment on original car. *jb
