The speedometer has become unreliable; it sticks / jerks while driving after which it does not display an accurate speed. I've had my speedometer read 30mph while completely stopped. It has a greater tendency to stick around 50-60mph. Repeatedly starting the engine, causing the speedometer to go through its reset cycle will move the needle back to 0mph in approximately 5mph increments for every start. This only provides a bit of reliability for short trips.

Myself and my daughter was visiting my parents in virginia and I turned the steering wheel to the right to go around a curve and the steering wheel didn't turn. I looked ay my daughter and said "oh _ _ _ _" and she ask me what 's wrong? I said the steering didn't turn and it wasn't but seconds later, we slammed into the side of the mountain on the driver side and we rolled two or three times and ended up on the roof. I immediately went unconscious because of the impact. I had a big gash on my head and was bleeding profusely and I was having trouble breathing because both of my lungs were punctured. All the windows burst out so my daughter was able to crawl out the passenger window to ask someone for help but my seat belt would not unbuckle so there was an issue getting me out. I was very lucky that someone that stopped had a pocket knife and cut the seatbelt to get me out. I had a bad concussion and I kept going in and out . I had three broken ribs, three pelvic fractures, a bad contusion on my elbow and I still have a swollen knot about two and a half inches on my left leg. I also have issues with my back and I am in constant pain and on impact, my seat belt jerked and caught my breast and I now have five cyst with the largest one being one inch and they are very painful. I have to watch it very closely because of a cancer risk called inflammation cancer. I was hospitalized for three days and I have to continue receiving medical care because of these injuries. My daughter is young and now she has back problems and ptsd and she also continues to receive medical care . This has really impacted and changed my life and my daughters life and I would really appreciate it if you would take the time to investigate these issues. We are going to have life long injuries and issues because of this accident. Thank you very much.

The heater levels started to go out. First 5, then 1 until it no longer worked at all. I got it repaired but the 5th level does not work any more. The left half of the radio/cd player no longer lights up. My gas gauge would only register a quarter tank and then would eventually dropped to empty. It no longer works at all. Most recently my speedometer will occasionally quit working or register the wrong speed. I have to shut the car off and restart until it works again. Also, my tachometer goes way up when I begin driving and the car seems to rev way up before it changes gears and jerks into gear. I questioned a mechanic about this, thinking it was the transmission, which it isn't. There doesn't seem to be enough power. I have constantly had issues with this trailblazer every since I purchased it. I also owned a blazer at one time and also had a lot of trouble with it. I should have known better to purchase another chevy, but never again!

After filling up my gas tank the fuel sensor read empty and the gas light was on. Also, whiel driving the fuel sensor would jump around showing empty, full and the gas light would come on. The vehcile was still under warranty at the time so I took it to the dealership to have it repaired. The service rep at the dealership inidcated that it was a common problem with the fuel sensor and it would need to be replaced. He mentioned that I was lucky the vehicle was still under warranty because the repair was very costly. My vehicle occassionaly lurches when it put inot gear from being parked or idle as if it wants to just take off right away. I contacted gm on this and they stated there was nothing they could do, but I have researched and found that many others have has this same problem. Another issude I have had was my speedometer and entire dash cluster failing. While driving on the interstate my speedometer jumped to over 100 MPH and then back down to 0. At that point it stopped working for a few minutes then started working properly again. Finally it stopped working altogether. I took it to my mechanic and he replaced the enitre cluster panel which cost me around $800.00. Again, he did some research and found this to be a common problem. I sent gm a letter with a copy of the repair bill along with documentation of the many complaints I found online with the same issue. I heard nothing. I reached out with a phone call and was told the issue did not warrant a recall. This could be a serious safety issue. Please consider a recall as it apperas this vehicle was just poorly made and many other people are experiencing the same issues.

Fuel gauge reads empty after filling tank, won't reset itself after fueling. Back hatch lock is stuck in lock and has already been replaced once. Sometime when your setting still at a red light or just going slow in traffic, there seems to be a "surge" of power or fuel to where the vehicle lurches forward. When driving at night the lights will flicker or dim on there own.

Driving down the road at 50 MPH and then you slow down. The speedometer stays at 50 MPH then when you speed up it goes up accordingly. When you stop the car completely the speedometer says you are still going 30 MPH. Then you have to shut the vehicle off and start it to try and reset it. Doing this only takes 8 MPH off so it takes a while. It seems to do it more in the cold weather than in warm weather. I think this is a major safety issue, due to the fact that you have no idea how fast/ slow you are truly going. And when the speedometer does decline with your speed it is very jerky and sticks.

The speedometer sticks at various speeds. Sometimes it shows *below* zero when I'm moving. Last night, I was traveling at approx. 65-70mph, I assume, but the speedometer was stuck at 30. When decelerating, the speedometer will stick at certain speeds, and then jerk down suddenly. My trailblazer only has about 53,000 miles on it. I have seen reports of this issue beginning at 30k, but most kick in at around 50k. I am calling the shop today. From what I've read, it's related to a faulty stepper motor. If I am able to update this report, I will. However, I think this is very unsafe and am not going to wait to report it until after the repair; I've seen at least 40 (I stopped counting) other complaints about a malfunctioning speedometer in 05 trailblazers on aboutautomobile.com (I also have issues with dimming lights and headlights flashing at night).
