Chevrolet Trailblazer owners have reported 32 problems related to check engine light on (under the engine and engine cooling category).
On two occasions now within a two week time frame, vehicle shuts off while driving. Both times I was in motion at approx. 25 to 35 mph. Get it over to put in park and it does start up so far. I have children and I commute on an extremely busy freeway. What if this failure occurs while I'm moving at 70mph plus? my mechanic has replaced some parts in hopes it was the problem. The check engine light is on/off for months but nothing of a major concern is showing up on the computer. I understand this vehicle has 150k miles but it should not be shutting down while driving. Please help.

The check engine light comes on&off a lot right after fueling, I took it to the GMC dealership&had the camshaft replaced because it kept cutting off every time I turned a curve. I tried to show or tell them about this GMC recall letter I got on my 2005 Chevrolet Trailblazer, but they said that it didn't apply because of the mileage&I told them the car is not 10yrs old& the paper is saying 10yrs/120,00 miles& for me to take it to the dealership so that the manger can send my bill & receipt in for reimbursement they wouldn't do it. I guess because I'm a woman. Driving to work on the interstate the car shut completely off. The car was still moving when all of a sudden all the lights and gage's lit up and the car cut off. It did not lock up so I was able to steer it from the middle lane of a three lane interstate highway to the grass on the side without getting killed or hurting someone else. I had just filled it up with gas with a quarter of a tank from the full line. Once I got the car to a complete stop and thanking god that this was not tragic,I put the car in park and waited a few minutes before starting it back up. It started back up as if nothing had happened. I took it to auto zone to get a free diagnostic check&it showed that nothing was wrong. A few weeks later after I would cut the car off the air conditioning would not stop&the engine light constantly comes on every other time I hit the brakes. I had to keep taking out fuse #35 to get it to stop even after the car was cut off just so the battery won't run down. Took it to the dealership and was charged an arm&leg to get it fixed. I showed them the recall letter again and they said it was too late for them or myself to do anything about it. I have all of my receipts & the letter from GMC about the recalls. Im sure my vehicle fits in there somewhere with these problems& truly would like 4 them 2 give my free car.

Vehicle stalls and shuts down everyday. Sometimes just stalls then accelerates, sometimes shuts off and I can switch to neutral and restart while coasting. Other times I get shutdown warning light and engine will not restart. I have to coast to the shoulder and wait. Engine will then struggle to restart and engine shakes violently. I wait a few minutes and it will start and run fine, sometime with check engine light on, sometimes not. Rpm gauge works sometimes, sometimes not. At time there has been no response when turning key to start. On going issue!! crankshaft position sensor has been replaced 3 times, and issue still persist. Major safety issue!!.

The contact owns a 2005 Chevrolet Trailblazer. The contact stated that while at a complete stop, the vehicle stalled with the illumination of the check engine warning light. The vehicle was able to be restarted but the warning light remained illuminated. The vehicle was taken to a private mechanic where the failure could not be replicated. The contact also mentioned that the failure was intermittent. The manufacturer was notified. The approximate failure mileage was 53,291 and current mileage was 59,000.
The truck has been at a several times into a chevorlet dealer, the check engine light the reduced engine light and the traction control lights all come on at the same time and it causes a failure in which the vehicle losses 90% of power . The failure happens at random time and all weather and traffic conditions. I have had it at two dealers as well have contacted gm executive dept. They have claimed to be fixed several times but it still fails. The issue at hand is that in traffic conditions this failure proves to be a huge safety hazard for myself and other drivers on the road. Its not a used car issue as its an electrical failure issue. I have asked time and time again to have a gm field tech come look at the car but, they insist that the dealer fix it. I need someone more to see and understand the failure comes with at great risks of other drivers on the road. If you goggle this problem you will see others have the issue and I think its worth a recall if they can find a fix for it but after 3 years and several tries they are still unable to fix the issue.
Sir/ MA'am, I noticed recently in the news that several gm product lines have been plagued by faulty ignition switches causing the vehicle to lose power and/or cut out. I implore you to look into the Trailblazers. I emailed gm while I was deployed (2012) and they gave me the runaround saying that it is not a documented problem, as expected. A simple internet search would show that a lot of other Trailblazer owners have bad ignition switches/ electrical issues that cause the vehicle to lose power at all speeds. My wife lost power going about 35 mph and I had my two children along with her. This is just one example, on one occasion. Granted, I do acknowledge this problem is intermittent, it still occurs at random and at all speeds. Gm tells me to go to a dealer and have them look at it. I refuse to pay gm any money to have a dealership rip me off for an ignition switch that is flawed and replace it with the same faulty oem style/model number. I have ran a scan tool looking for codes and it doesn't have any. Like stated previously, this is another line of gm that is plagued with ignition and electrical issues that gm refuses to take ownership of. The mileage I have entered is approximate. I cannot remember exact numbers, but it has happened for years, intermittently. When the vehicle has coasted to it's final destination after losing power, it starts up and drives normal again after it is put back into park. Also keep in mind that it doesn't show any check engine lights, indicating a problem or need of servicing. Again, please look into this product line as I know the result(s) will show that gm is liable and I don't want any fatalities because nobody spoke up about it.
Recently, I filled my gas tank & low fuel light warning displayed and low fuel light came on. Since then the check engine light is on steady (not blinking) most of the time. The fuel gauge floats back and forth never really letting you know it's true status. The dealers and public know about this issue- yet chevy refuses to take responsibility and fix the product. It is frustrating & nerve wracking to never know how much fuel you have at any given time, as well as the constant warning lights/ chimes during driving. This is the second serious issue I have had with this vehicle- just a month before had to repair safety issue of stabilitrak turning on at random, after twice it slowed my vehicle- without warning- on the thruway from 55 mph to about 20 mph. I had documentation of 4 trips to dealer for this concern within the first year of ownership but "the computer doesn't show a problem" so 5 years later I finally had the code show up after a close call almost accident. This concern is all over the internet as well & even with contacting Chevrolet & the nys attorney general they still only covered half the cost of the repair. Chevrolet needs to take responsibility for the safety of their products and obviously will not unless recalls are mandated- I urge you to do just that. Thank you.
My 2003 chevy Trailblazer check engine light comes on accompanied by the low engnie power light. The vehicle goes into limp mode. This is a safety feature that allows the computer to protect the engine from any damage should something go wrong. The only problem is that there is nothing wrong. This happens multiple times a day (6-8). Changing sensors doesn't fix it. I believe it to be a problem with the 2003 chevy Trailblazer computer. I have read many forums with hundreds of people that have this same problem. Please look into it before it causes an accident or makes an emergency situation a fatal one.

I was wondering how come there hasn't been a recall for the chevy Trailblazer ext for the throttle body. I see that they have recalls on other chevy cars with the same issue. This is a very dangerous issue as when this goes you have a reduce engine light that comes on. Which I didn't know what that meant until my car wasn't going any more than 20 mph. This is very dangerous to be on the road like I was and can't speed up or better yet trying to turn when you don't have the power to do so. Also, I see that there were also alot of issues with the speedometer. Which also I had that problem has to pay too much money to get this fixed. As how they would say their are manufacture parts which definitely hurts your pockets. If they know that they have these issues they really need to rectify because both of these issues cause some serious problems on the road. I know they are wear and tear on cars / trucks but if you have too many people having the same problems I think they should do something to resolve these issues.

I was driving home from work and started hearing the trucks undercarriage start to rattle and grind on the bumps of the road. I had a sudden loss of power on engine and it wouldnt respond to my pressing on the gas. I believed that I had gas in the truck because the gauge read half full and apparently I was out of gas. So I proceeded to pull into a gas station and as soon as we filled up, the truck would not start! I saw that my check engine light was on and had to ask for a jumpstart to get it started again. At another time and date again the truck went dead, I asked for a jumpstart and the vehicle would not respond. I now had to buy a new battery because the car damaged the original battery and now with the new battery installed my car starts but will not stay on without me pressing on the gas while in park gear. I believe something may be defective with the electrical gauges, fuel delivery system, and suspension.

A 2006 Chevrolet Trailblazer. The air conditioning unit, harness and the master switch on the drivers side window failed. The check engine light illuminated whenever the vehicle was turned off. The master switch malfunction prevented all the windows from working properly. Only 1 speaker works radio plays at low volume.
When I did a routine fill up on my vehicle and upon restarting the car after completion, the fuel gauge showed empty and the low fuel light came on. I turned the vehicle off and then turned it back on and it still showed low fuel. As I was driving the vehicle home, I noticed the check engine light came on. After driving the vehicle for about 20 miles or so, the fuel gauge showed correctly and the check engine light went off. However, upon the next fill up, it did the same thing. Now, it is at the point that it doesn't register the gas in the vehicle at all. One minute it shows empty, the next it shows correctly, and then it slowly goes back to empty. I have to use the trip gauge to know how much gas I have in my vehicle at all times. The check engine light comes on every time the fuel gauge shows empty. Lately, over the last few days, the car is starting to hesitate as if it was going to stall on me upon take off. I am getting worried that this vehicle is going to stall on me as I am driving and cause an accident.

My gas gauge always reads empty even when the car is full. Engine light always goes on and off between a matter of days. Recently my heat went out in my car we changed the resistor and found out one of the prongs were burnt out. A week later the heat went out again. Looked at the resistor and the same prong was burnt out!! I'm getting really fed up with this vehicle!.

When we bought our 2005 chevy Trailblazer we had to turn it around and take it back to the dealership. The check engine light came on. All they did was reset it. It came back on some time later, we took it back to dealership they got it worked in at the nearest chevy shop, they reset the light and we were told to buy a gascap for it. We bought the gas cap, light stayed off until now. We have taken our 2005 chevy Trailblazer to the local shop they hooked it up to the computer and found nothing wrong. So far nothing has been done, but since the light is on it is a gas guzzler with light on getting 6 miles to the gallon. With gas at 2. 59 a gallon that's not cheap. Chevrolet dealer in town says its probably the throttle body needs cleaning, and it needs a new battery. They say the throttle body is a common problem in the new models, because the gas is not fit for the newer model vehicles.
I have been reporting this same problem for over 4 years to onstar and gm that I had issues with the headlights dimming upon stopping at going. I have called onstar and was told nothing was wrong with my SUV. I have also saw a engine light flash, called onstar and nothing was showing wrong. Today, my vehicle engine light and battery light came on and I was informed by onstart that the generator/alternator needs to be replaced. Vehicle has 58k miles.
The engine light goes on sometimes and sometimes off or sometimes blinking. The car was taken in to check the computer read out to find it is a misfire and I was told the repair would cost almost $4000. 00. One time, the radio sounded 3 beeps and said "fire on", I shut off the car and it continued, took out the keys, still continued. Was told never heard of such a thing from the dealer and on star when I did a diagnostic . On star said my oil is registering -- however the car says 99% remains. Lights go dim especially when applying brakes and sometimes whenever. Check engine light comes on sometimes and then goes off. Sometimes flashes during idle and sometimes not. Since computer has been cleared, engine light has not come on for one day but the gas mileage is very bad since I had it in to check about the light. By the way, nothing was fixed but I was charged $148. 50 to find out my fairly new vehicle with 27,000 mis. Is broke. I was told the head needs replaced. They are having problems with them. Why do I have to pay for their problems?.
Purchased vehicle on 09-08, with roughly 45000, check engine light comes on and off, after several months of going back and forth at chevy dealer they determined it was a faulty cylinder head on the number four cylinder. Filed bbc complant and spoke with chevy who refused to do anything. Couple months later and approx mileage 60000, the fuel gauge no longer works causing me to run out of gas a couple different times. About the same time, the stability control system dash lights would intermittingly come on and off. I have not contacted chevy about the other two issues as I felt they would not do anything the same as the head problem.

I bought my 2005 Trailblazer the same year with 19+k miles. I started having it stall on me around 30k miles. I took it to hayward, CA chevy dealership because it was still under warranty. They said that they found nothing. I took in again because the engine light came up and they said the problem was the light only but, that's the light that would flash when it stalls. I took the car back in several times for the same situation. At the time, I had 2 boys. . . . . 8yrs and 6yrs and this started too become unreliable because I was putting them at risk and not only that, I would stall and then take a few minutes to start again. I've been told that maybe it stalls because the engine was not warm but I know that it can't be it because a few times I was on long road trips and the engine would stall on and off. This has been an ongoing problem since 06 and it's a horrible risk because it's stalls while driving. My kids and I can get hit from behind. I don't know who else to repost this too. I bought another car 5/07 because this vehicle is not reliable but use it when I have to and up to this day, it still stalls.

Subject:reduced power problem with Trailblazer comments: I have a two year old chevy Trailblazer that has on three occasions had a dramatic loss of power and a reduced engine power light comes on and loses all acceleration. Twice this happened while I was on the highway, and I feared for my safety and the safety of my toddler, as my car slowed from 65 mph to 40 mph in a matter of seconds, and would not accelerate. According to the dealership, there is a problem with an electronic sensor to the accelerator. I have tried to raise this with Chevrolet customer service, who blatantly disregarded my safety concerns and told me that my concerns would go no further up than the customer service desk level and they could offer me no assistance. Based on my research, this is a documented manufacturing defect, however, gm refuses to recall any cars and claims that the bulletin documenting the problem only serves to assist dealers in the repair. I am concerned for the safety of all Trailblazer owners, and believe that chevy and gm need to be investigated for ignoring this dangerous safety issue. From NHTSA web site.
