general problems of the 2005 Chevrolet Trailblazer

I was driving on the highway going straight no turns in my 05 chevy Trailblazer going about 60mph and all of a sudden I heard a low click sound and I was not able to accelerate or keep my current speed it was beyond unsafe so I pulled to the side of the highway engine running still I put it in every gear to see if it would move it did not I tried r,d,3,2&1 gears and the truck only rev'd up and did not move . It was no signs of the transmission going out or going bad it still shifted smooth it just went out all of a sudden on the highway which is very dangerous I feel like the transmission has to be cheaply made .

Our vehicle died at a turn signal light in a dangerous intersection. No warning from the vehicle as it was running normal. It would turn over but no start. Police force a tow out of the busy intersection right away. It starts up at the mechanics. They tested fuel filter and other stuff. We get on the highway in traffic and get 6 miles out and no warning we die and had to push the car to the shoulder on in dangerous conditions. Sit for 2 hours and it fires up. So we found shade and waited for cool down. 2 hours away from home and it took us 9 hours to get home. We drove it to the store and when we were done shopping it fired up. Went around the corner to other store and shopped 2 hours and came out and it would turn and no start. Tried starting every 30 minutes to hour from 9:30pm to 1:40am and then it fired right up then drove 30 minutes to home. After researching and finding quite a few with same year make and model having the same issue we found that it is the pwr/trn relay plug in area in the fuse relay center. When we broke the plastic off the relay and wrapped a rubber band around it so it's constant contact and plug it in, it will fire up every time. I can drive it all day like that with no issues. I have to turn the key from running to accessory mode then remove the rubber band and then power off the car. Don't want to fry com. The relays are good and problem is the fuse relay center. Chevrolet said themselves that this model is notorious for fuse relay center problems and usually require replacement. It's a known defect. There are two pictures attached from one of the other people with same vehicle same problem and in order to make his fuse relay center work properly he had to wire/reroute his pwr/trn relay as seen in the picture. This needs to be investigated as this is a well known issue with Chevrolet and the Trailblazer.

When I accelerate from 45 to 60 miles per hour my whole truck vibrates and it feels like the engine is seizing but if I accelerate more or reduce my speed it goes away. I was researching online and found out I wasnt the only one in the country that has this problem. I was just thinking of everyone's safety including my own.

The contact owns a 2005 Chevrolet Trailblazer. When the contact shifted the gearshift in reverse, the vehicle failed to drive. In addition, when depressing the accelerator pedal, the vehicle would only increase one gram rpm. The vehicle was taken to the dealer where it was diagnosed that the forward gear was locked in with the loss of park and reverse and the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 163,672.

The contact owns a 2005 Chevrolet Trailblazer. While operating the vehicle, smoke emitted from the hood. The contact pulled over and discovered flames under the hood. The fire department extinguished the fire. The vehicle was taken to an independent mechanic where it was diagnosed that the failure was due to a failed gm/ac delco transmission coolant line fitting, which caused transmission coolant to leak out onto the catalytic converter and exhaust system. The manufacturer was not notified of the failure. The vehicle was not diagnosed or repaired. The failure mileage was 120,000.

On July 29, 2015 I exited the freeway, and suddenly my 2005 chevy Trailblazer ext 4. 2l began to stall and would not proceed upon acceleration. After calling the gm corporate office, I asked if there was a possible warranty on the vehicles transmission, they stated "no". . . However, the representative did tell me that my used 2005 Trailblazer ext did have the transmission replaced in 2007. This is 2 years after the vehicle hit the road spanking brand new. There has to be a problem with the chevy Trailblazers transmission. I ended up spending a total of $1,600. 00 for a rebuilt transmission. I am now looking to possibly trade my Trailblazer in soon. Looking at the complaints here in this forum regarding the failure of the chevy Trailblazer transmission is ridiculous. Gm refuses to own up to their mistake. It would be nice to see NHTSA get strict with automotive manufacturers. What will it take before someone listens to the consumer, a death? that could have easily been my fate; luckily, it happened when exiting the freeway.

The contact owns a 2005 Chevrolet Trailblazer. The contact stated that while attempting to accelerate, the vehicle shifted abruptly into second gear, and from second gear into third gear. The failure recurred multiple times. The vehicle was taken to a dealer for diagnostic testing. The first and second shift sensor in the transmission were replaced. The failure recurred, and the second and third shift sensor were replaced but the failure recurred. The vehicle was then taken to an independent mechanic who stated that the valve body needed to be replaced. The vehicle was repaired. The manufacturer was notified of the failure. The approximate failure mileage was 132,000.

While we were driving on I-94 near mile marker 12 in michigan, the rear axle broke, making the car inoperable. We were able to coast to the shoulder of the interstate.

Steering wheel malfunctions, car turns off when wheel is extended too far to the left. Seatbelts for last row of seats dont lock, radio is stuck, buttons dont control radio properly.

Crashed straight into the back end of a vehicle doing 60 while I was doing atleast 80, or 85, maybe more, I don't remember. The first thing I remember seeing is realizing I'm alright despite the blood in the cockpit and on my face despite sneezing which was spreading blood. Is this a vehicle defect or what? my math says that crashing at 85mph into a vehicle doing 60 is like crashing into a brick wall at 25mph. I've had a local mechanic check it out and he says according to his obd-ii computer everything is working fine (or was atleast) :) anyways, please feel free to contact me again with any more question you may have.

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.

I am not sure what is wrong with this car! I have had it at the mechanic several times. He has replaced some sensors but the car still. . . Putters. . Putters. . And putters. . . . . . Help!!! the car jerks, putters and sometimes dies while driving!.

My 2005 Trailblazer has begun to have several problems and in speaking to other chevy owners the same problems have been found in other models and years of chevy trucks and suvs. I'm very disappointed to see that chevy chooses not to recall, which is why I'll never purchase another Chevrolet. Beginning a few months ago my gauges began to be erratic. Starting with my speedometer sticking at zero and then later sticking at 60mph even while sitting still. Sometimes it works and sometimes it doesn't. Next while sitting at traffice lights or stops signs my engine began to surge forward without applying the gas. When the vehicle surges the rpm gauge also jumps up. I already replaced one transmission at 50k miles and now since passing 100k miles have begun to have rough shifting again in my vehicle. I do not drive my vehicle in a rough manner, speed, or haul a trailer, so there is no reason to be going through transmissions. Now my fuel gauge has stopped working and I'm having to track my mileage with my odometer. I've never seen a vehicle with so many problems and no help offered from the maker. * tr.

I have been hearing a clicking noise and my car had begun sounding like a jet engine taking off for the last 3 days - very noisy. I took it to pep boys where I was told that it is normal for the Trailblazer to begin making this noise shortly after 60k miles. I was told the serpentine belt needed to be replaced, tensioner pulley and the idler pulley. I had the new parts installed. None of my warning lights came on the dashboard so I assumed was well as there was no other indication that something was wrong. Driving my car within 24 hours of being fixed, the fan clutch seized and my water pump burst causing car to overheat in the middle of an intersection where my car then stalled putting me and my children at risk for injury. The car almost caught on fire it was smoking severely. Someone helped me move my car out of the busy intersection and I called my husband and a tow truck to come get the car. When I got home and looked up the problems again on the dealer website, I found hundreds of forums where the fan clutch has been mentioned and the water pump too. A fan clutch according to the mechanics I surveyed stated they should last at least 100k or more. This has been brought to gm and they ignore it. It is a safety issue. Additionally, my speedomter hasn't worked for at least a year and when I called chevy they wanted to charge me $700 to replace it when it is not my issues. I didn't cause it. Not knowing what speed you are going is definitely a safety hazard and can cause accidents or tickets. . Read more...

Is not longer working broken.

The transmission shifted hard from first to second gear. The transmission shifted so hard that it almost jerked the steering wheel out of the consumers hands. The second concern was when the consumer had to place the rear seat down to place items in the back , it required that the front seat be moved forward and would not go all the way back again. The last concern was that the vehicle could not use tire chains due to the fact that there wasn't enough clearance and the consumer was informed to use another traction device.
