Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Instead of pointing to the speed I was going, the speedometer needle kept moving a little to each side. Now it reads consistently too high, and I don't know what speed I'm going. I've read a lot of complaints about this, which say that GM won't admit it's a defect, and I can expect other gauges on the instrument panel (tachometer, fuel gauge, etc.) to break, too.

The speedometer on my 2004 Chevy Trailblazer started to malfunction. The speedometer will stick. I looked up the problem and found other people with the same problem. When I called Chevy they told me that my car was not covered for this "special policy".

I was driving to work one morning and notice that my speedometer in my 2004 Chevy Trailblazer appeared to be malfunctioning. I got to a stop sign and stopped. My speedometer only went down to 30 never down to zero at a complete stop. As I started through a intersection my speedometer went from 30 to a 120 on a rural country road. At the next stop sign the speedometer stayed at 120. As I proceeded, the speedometer went completely around and stopped where the trip miles are located. I never knew through the rest of my trip to work exactly how fast I was really going.

Speedometer not functioning properly, it showed I was doing 35 mph sitting at a stop light. I had to turn the vehicle off and on to get the speedometer to drop back down, which it did in 5mph increments. I also have problems with the gas gauge showing empty when it is full.

I have a 2004 Chevy Trailblazer. The speedometer went out last August. It started with staying on 20 mph while I was stopped and engine was off. Now it has since stopped completely. It is now stuck clockwise at about 150 mph with the gauge pointing to neutral.

Speedometer and RPM gauge do not work. They are completely inaccurate. For example, it show 120 mph when I'm going 50mph. At first it only messed up sometimes. Now it is never accurate. I have not fixed it. From what I have researched, many other people are having the same problem, but GM has not issued a recall for that on the Trailblazer (to my knowledge).

I began having problems with speedometer and tachometer several months ago. The tac and speedometer go crazy and then go dead while driving down the road. I took it in and was told that it was a faulty gauge cluster that needed to be replaced and that it was a problem already recalled in other GM vehicles. The service tech was able to unhook the battery cable and reset the gauges but they still aren't fixed. I have been reading multitudes of complaints of the same thing. My Trailblazer started doing this around 51,000 miles!

Speedometer started to flutter about 2 weeks ago. Speedometer completely broken now. Unable to tell how fast car is going nothing has been done yet. Contacted the manufacturer because several other SUVS have had this same problem. They only fix certain SUVS. They will not fix Trailblazers or recall the instrument panel cluster which is the problem. They are only recalling some of the other SUVS including Yukon and Avalanche.

First the tach quit working and now the speedometer and cruise control are erratic. Have spoken with GM customer service and taken it in to the dealership for diagnosis. The are fully aware of the problems but unwilling to stand behind their produce or fix it.

The contact owns a 2004 Chevrolet Trailblazer. The contact stated that the tachometer and speedometer were behaving erratically on a regular basis. He could not tell if he was driving 2 mph or 200 mph due to the irregularity of the indicators. The vehicle was taken to the dealer and they stated that the extended warranty did not cover the vehicle, as well as other Chevrolet models that were included in a recall for this same failure. The cost of the repair ranged from $600-$800. The VIN was unknown. The current mileage was 65,000 and failure mileage was approximately 64,000.

The contact owns a 2004 Chevrolet Trailblazer. Beginning in January of 2007, the gas gauge failed on the instrument panel, which prevented the contact from knowing the amount of fuel in the vehicle. Soon afterwards, the speedometer began to malfunction and began displaying inaccurate readings. The vehicle has not been repaired, but arrangements are being made. The current mileage was 84,585 and failure mileage was 73,068.

Normal operating of 2004 Trailblazer, 15,000 orig miles. Driving approximately 40 mph, speedometer reading 110 mph, when stopped speedometer reads 60 mph, just stopped working suddenly, no warning leading up to this problem. -this has not been corrected to date. Safety and tickets are a major factor not knowing what speed you are driving...

When temperatures are cool, below 40 degrees F the tachometer doesn't work at all. Once the car has been driven awhile and "warmed up" the tachometer begins working.

  • Automatic transmission

I have a 2004 Chevy Trailblazer with 45,000 miles on it. I was driving along the other day and noticed my RPM gauge bouncing around. Five minutes later I looked down and was going 120 mph in a school zone. I just happened to be sitting still. Once I began moving the speedometer was bouncing like crazy. I have no idea what will be next, maybe filling full of gas and still be on empty?

I own a '04 Trailblazer and a couple of months ago my oil pressure gauge started sticking. Then temp. Gauge was sticking, battery gauge stuck, and speedometer stopped working. I have owned this vehicle for less than a year and do not have the money to replace the dash cluster. If GM can issue a recall on the other vehicles somebody should force them to issue a recall for the Trailblazers also. This is a safety issue that they should be responsible for not us the consumers.
