Alternator/generator/regulator Problems of Chevrolet Trailblazer - part 1

Stabilitrak light comes on intermittently for no apparent reason. Have had brake fluid, brake pads, rotors, sensors and tires replaced. Traction control and abs checked; all is good. No cel code relating to this issue. Traction control off button doesn't work once light appears. There is no difference in driving when light is on. Still haven't figured out what causes it. Battery, power cords, and alternator have both had to be replaced do to issues with the voltage outputs. Now to replace fuse box and ecm due to more voltage output issues. Cel has had no indications of an ecm, fuse box, alternator, or battery problem until they were beyond repair (this also happened with other transfer case leak, loss of reverse gear, and front differential leak) . Cel comes and goes by itself at anytime with no difference in drivability or conditions. Each time it reappeard it's thrown different sensors and/or circuits failing or high/low voltages including O2, maf, tps, evap system, wheel speed, fuel pressure, oil pressure, steering wheel, gas and brake pedal position, air bag impact, just to name a few. My car has recently started going into limp mode at random due to this electrical issue. Only remedy for this problem is disconnecting the wiring harness and allowing the fuse box and ecm to cool down. And finally, my oil filler tube seal broke and oil was spitting out into engine bay. Coincidentally, my pcv valve tube had also broken, and the tube was hanging loose right in front of the oil filler tube. As a result, pcv tubing sucked up a large amount of oil into the air intake; with no check engine light illumination indicating any problems during the time of failure. My air intake system is nearly ruined (not to mention the $$$ I shelled out in oil) and the wear down on parts has been detrimental to the life of the engine. This car is nothing but a cash cow for gm.

Most of the gauges are very erratic when in motion or stopped. Tachometer jumps around, oil pressure reads all over, speedometer goes to zero or full scale, amp meter drops below 14 and lights dim when this happens, (have had the alternator replaced 3 times, this is quite a safety concern for me as I have no idea what to believe on any of the gauges. No repair shop has been able to solve the problem.

At a red light and attempted to close the driver's side electric window. When I pressed the buttom to raise the window the window stopped raising to a closed position and heard a loud noise similar to glass crumbling inside driver door. Is the regulator covered under a recall. I previously had the driver's door master power window switch module replaced due to a recall. I have always had problems with the driver's side window mechanism always slowing down and stopping midway during cold temperatures.

Takata recall, my 2008 chevy Trailblazer has 110,000 miles on it and for the past year it seems that I've been having electrical problems. This problem have been going on for about 6 month. Every now and then my car wont start and I have to get a boost off to get it started again. I took my SUV to get the battery and alternator checked and they said everything looked great. Then after that I noticed that my rear brake lights were going haywire with blinking lights going on and off and the car was not on. After I noticed the blinking lights, I went to try to start the car and it was dead. Also, my front passenger door motor went out , so the window wont go up or down. . This is very frustrating can someone please tell me if there are recalls on any of these problems.

I have bought 2 new batteries with in a month of each other due to my battery being dead over and over again. I was told my alternator was fine only that something keeps draining the life out of my battery. This has been going on for months. If I let the Trailblazer sit for 1 to 2 days the battery is dead again. I also noticed that the face of my radio has started to get hot. When we first had auto zone change the battery we noticed that it caused our air vents to stop working. I looked this up on line and it looks like I'm not the only one who has this problem. I see it's a big problem. I don't know if there is a recall , but I'm scared it is a electrical problem that could hurt me and my 4 kids if it happens while driving. Can you please help me with this.

Drivers door window regulator want out. This vehicle has a recall #12180 for door switch replacement which fluid can enter drivers door and can cause shorts.

This is just the most recent of electrical problems I have had with the 2003 Trailblazer lt. Since the vehicle reached about 47000 miles I have had repetitive electrical problem: ac went out, radio went out, replace alternators three times batteries 4, refusal to start, some power vampire sucking out the power, and now I am driving along and the entire instrument cluster stops working. I get to the grocery store and shop then come out and it is working again. Then the next day, none of the gauges are working from the time I started it. I called chevy at 1-800-222-1020 and was informed there is no recall, but I see this is a common problem according to on-line complaints. Sean, at Chevrolet said they can't do anything until it is seen by a dealer. I have evaluation appointment set for 3/4/2013.

Pushed to put passenger window down and would not go up, stuck open. Evidently the window regulator broke at a part cost of about 300. 00. Just had in for a blower problem where the blower came on while the car was just sitting in the garage with no keys or anyone in it. That was 400. 00 some dollars. This car does not seem like it should be having these problems.

First my speed gauge started going crazy reading different everytime I crank the vehicle then the alternator gauge started reading off the chart my highest number on the gauge is 19 it is reading at the 210 on the temp gauge that is how far past the 19 it is today however it may be different later I love chevy my family are all chevy people and it is sad that chevy has forgotten about there customers I am in law school not long left when I am finished I am filing a suit for all the people who own this vehicle chevy needs to step up an take responsibility it is not a fluke that this many people are having the same problems and it is ridiculous that chevy has dropped so low that they expect us to just eat these problem well quite frankly I am full up of the bs I am also writing my local paper and news station and I will bug them until they run an article and air these problems an some other problems these vehicles are having chevy won't fix our problems they won't listen to the ones whom keep them in business well maybe they will listen to a judge step up chevy it is crazy that you won't take responsibility for malfunctioning parts you will see your day in court. ## VIN failed ##.

I don't have exact date I bought my vehicle it is just an estimate. But issue has happened twice now. Also don't have VIN with me but can get it if needed. I bought my vehicle about 2 years ago. When I bought it the passenger window regulator went out. Lamb's Chevrolet in onida, sd replaced it. Now a few months ago the passenger regulator went out again. They told me well they only have a 1 year warranty on them. Warranty or not it should have not gone out within a couple of years. I am fighting with them on paying for it. Is there any other complaints or recalls on window regulators with the chevy Trailblazers? I shouldn't have to be replacing this every couple of years. Also they have one excuse after another why it could have gone out while all in all they probably put in a defective or refurbished one which dealer these days are famous for and charging customers full price.

Even if this car is well maintained it sadly as serious electrical issues that chevy does not want to come to terms with. The speedometer goes out and in and reads incorrectly as well as the rest of the gauges at random points in time. The heating system needs replaces and the alternator consistently needs to be replaced even when the maintenance of the car is maintained. It is a consistent struggle to keep the car running even if it is not on high miles and it is a sad product for chevy.

I bought my 2007 Trailblazer in September 2012. I was so excited, but a few days after purchase the driver door window regulator stopped working. I contacted chevy and they told me there were no open recalls on this yet and are continuing to tell me this. They wanted over $500 to fix the issue for me. When I looked I noticed that there are recalls on this item, but still chevy keeps telling me there is no open recall. I am scared after reading other complaints that this could lead to a possible fire.

The drivers side window control panel would not work for any of the windows. The vehicle was not running. I checked the fuse and found it to be blown. I replaced it with the exact same size and type of fuse. Then I tried to roll up the drivers side window. The door window control panel switch then began to smoke and there was the smell of burning electronics and plastic. I took it to the dealership and was told the control panel and regulator had fried and would need to be completely replaced.

I was driving home from work and started smelling burned wires - then smoke started pouring out of all creases in my driver side door. I pulled over and had a drink with me and dumped the whole thing into the door to get it to stop. Fire dept came and told me not to drive the vehicle and had it towed to the dealership. The dealership determined in was a faulty driver door window regulator and it had a hole burned through it. . Read more...

Every couple months the alternator goes out I am almost to the limit on my warranty returns. The first time it went out it wasn't charging then several times after that it went out was over charging and in doing so damaged my battery so I had to pay to replace it also. I have had nothing but problems with this car and is becoming a money pit.

The contact owns a 2006 Chevrolet Trailblazer. The contact stated that the headlights and the heating system failed intermittently. The dealer replaced the battery and alternator however, the headlight and heating system continued to fail intermittently and without warning. The failure mileage was 700 and the approximate current mileage was 57,000.

I have had several problems with my window regulators, I had the switch and electrical replaced on the driver side door and I am having a problem with the window not working again. Also, now the window regulator is broken on the passenger side door. At the same time I am also having an issue with the electrical, I can tell that in combination with the window problems the lighting on the dashboard where the light is dimmed on one side. Overall, the windows are a huge safety concern with the fact they won't roll up or down depending on the issue and I'm concerned with the fire concern because it does it appear when the dealership fixed the driver side window there appeared to be melting of something that could have been burnt.

When starting the vehicle, it periodically will not start, lose all power, key gets stuck in the ignition without ability to return ignition to off position. There is a sound (like a high voltage sound coming from a transformer) and eventually resets itself, until 2 days ago. It would not reset itself, resulting in it being towed to a repair center. They indicated it was the alternator and battery and after changing both, the service engine soon light came back on and the high voltage sound has returned. There are times the rear wiper will turn on without my touching anything and times where the rpm gage will get stuck.

March 30, 2011, I spent $80. 00 on fuel to fill my Trailblazer with gas. I started driving and the gas gauge never moved, and was still showing empty with the low fuel warning chiming. When I was almost home the fuel gauge finally started moving but never went past a half tank. I inspected the vehicle to see if there were any signs of a fuel leak and nothing looked out of the ordinary. When I had to leave again to run errands the fuel gauge would move, however, it would go back down to empty when I was stopped or put the car in park. I have also had issues with rear tail light panel wires frying and having to replace those when there were no apparent causes (moisture, etc. ). Lights dimming while I roll up a window or push other buttons in the car (radio, climate control) and lights in certain areas of the car just blowing out. Fuses are fine, alternator and battery are fine. Why is this vehicle having so many problems at 56,000 miles? I understand that these are not life threatening issues, but what is next. Why do I have to constantly monitor my mileage just to make sure I don't stall or run out of gas when I am driving. Are we the customers supposed to shell out $$$ to have repairs done continually on defective equipment and components. I don't think so. GMC needs to drastically improve the quality and durability of their products, and step up to the plate and take care of the customers they do have. Word of mouth is way more effective than millions of dollars in advertising.

My headlights started to flicker one seasonably winter day. I had the heater motor replaced 2 months prior to this incident and back wiper motor just a month before this. Then the heater motor cut out, and did so numerous times as I traveled on a 20 degree day. It seemed to run fine after that for the most part that day. I later got into it and again headlights flickered and heater motor cut out. Especially when I would accelerate or turn to the right. I replaced the battery, alternator and had ground wires cleaned only to have it recur a week later. I do most of my driving at night and when the lights went out and came back on I had had enough. This had become quite costly and my mechanic was at a loss as to what to do next. I took it to a chevy dealer and traded it in on another vehicle, as I can no longer afford to keep spending money on a mystery issue.

I bought a 2002 chev. Trailblazer ltz from joe cecconis dealership. My alternator was bad they told me when I bought it and so they replaced it in 2008. Wed. Nov. 18th 2010 it caught on fire while I was in it. The local fire dept. Made a report and joe cecconis wont return my calls. What do I do?.

Lights dimming and flashing alternator not charging, wiring problem, dealer has no answer. I have vehicle just started this at 74000 miles, was fine up until that point. Heater fan works intermittently. Ghost electrical problems with door locks, radio , high beams. Very scary to drive.

I have had several problems with my power windows going up and down and then just not working at all. I smell smoke sometimes but can't locate the cause of the smoke. I have also had problems with the electrical connection to the radio, which also works sometimes but the majority of the time it does not work. I have had this problem for a long time now and need a resolution before my SUV catches fire. I also have problems with the drivers side power door lock which works intermittantly-whenever it pleases. I recently started having problems with my rear wiper blade-turn it on and it moves a little then stops. My headlights dim up and down while driving. . . I have replaced the alternator and the battery and still don't have enought power for some reason-dealerships want to charge a lot of money just to diagnose when it appears that this is obviously a defect in the electrical system of the SUV.

Instrument panel gauges malfunction and show improper readings. For instance tachometer shows 5000 rpm at idle. Alternator gauge is off the scale. Temperature gauge is also showing false reading. Oil pressure gauge is also false. Incident date is approximate. Individual gauges failed over time.

Instrument cluster panel stops working. Gas gauge shows empty, battery light appears, oil gauge and other instruments start acting erratically. I had my 2003 chevy Trailblazer at the dealer several times. 1st time they replaced the alternator, next time I was told the battery was weak. I had the battery checked at another location and it tested fine. My instruments are not registering properly again. This is about the 4th time this has happened and I don't want to be stuck somewhere along the highway. I never know when this problem will restart.

2005 Trailblazer alternator voltage dips alot as you drive. Radio does not work unless it is 100deg, then only one speaker works. Gas gauge reads empty after I filled up. Ignition is very hard to turn, you have to keep inserting and removing key until it frees itself.

Headlights intermittently 'flash' for a second during first 5-10 minutes of driving. Have replaced alternator and idler pulley. Gm suggests letting vehicle idle 1+ minute after start before engaging gear; this sometimes works. Dangerous and distracting to other motorists, as it appears to them like my vehicle is flashing its highbeams.

Headlights dim and volt meter drops randomly. Most evident at night, of course. Sometimes headlights fail completely for several seconds. Dealer has replaced alternator and fuse block but neither fix corrected the problem.

Speedometer, generator gauge, and oil pressure gauge stopped working over three years ago. I checked for a recall but was told there was not one on this model. I was told there were recalls for other Chevrolet vehicles, and kept waiting for a notice regarding the Trailblazer. I am worried now the fuel gauge will stop working. The mileage is now at almost 81,000 miles. The speedometer and other gauge issues create a very hazardous problem, and is detrimental to the safety of me and my children / other passengers. I would like to be notified of a recall notice.

The contact owns a 2006 Chevrolet Trailblazer. While driving approximately 45 mph, the battery indicator illuminated on the instrument panel. Ten seconds later, the brakes failed and the brake pedal extended to the floor. The contact had to apply the emergency brake in order to stop the vehicle. She drove to a nearby dealer and was informed that the alternator failed while driving and did not produce enough energy to the brakes in order to stop. The dealer replaced the alternator and the battery. The contact believes that this is a safety hazard and the manufacturer should issue a recall. Through online research, he found numerous complaints for this same defect. The current and failure mileages were 33,900.

I have had several problems with the electrical system in my 05 Trailblazer. Now I'm pretty sure the alternator needs replaced. It has already been to the shop once for electrical related problems and the vehicle only had 77,000 mile on it.

Purchased used 38k miles problems started straight away reardoor locks quit, child safety lock rod fell off broken clip, would find plastic trim on ground next to car,seat trim broken fell off, when it rains or snows 4 wheel unit fail to engage and disengage correctly engine light comes on and goes out alot alternator is loud water pump went out ,rear chevy emblem popped off we now have 56k can't imagine what's next.

Fuel just stopped working, driving down the road and headlights start dimming gauges go all over the board. Put a new battery in, changed the alternator and it continues to do this. Check engine light keeps coming on for oxygen sensor had that replaced 1 year ago needs replaced again.

The contact owns a 2005 Chevrolet Trailblazer. While driving approximately 50 mph, the contact heard a loud noise outside the vehicle. The transmission began to slip and there were no warning indicators illuminated on the instrument panel. The vehicle was taken to an independent mechanic on two separate occasions for inspection. The technician stated that the alternator failed. The warranty expired on the vehicle and the manufacturer is in the process of being notified. The vehicle is able to be driven and has not been repaired. The VIN was unknown. The failure mileage was 72,000 and current mileage was 76,000.
