2004 Chevrolet Trailblazer: adaptive cruise control problems

Filed Jul 17, 2014 · Acceleration, Electrical · 42,950 miles · OK

I can start my vehicle and the gauges started sticking. I am constantly being shocked by the driver door. My gauges no longer work at all and have completely went haywire. I have no dash lights. My vehicle has just died in the middle of a busy street. I do not know how much fuel I have, how fast I am going. My cruise control either at times increases my speed or does not hold the speed. I have to use a GPS device to know approximate speed. This vehicle needs to be recalled. I love my vehicle but it has tons of issues.

My 2004 chevrolet trailblazer 4x4 v6 is experiencing some instrument panel cluster problems. This is the second time as I had the instrument panel cluster entirely replaced once already. The fist time, the tachometer stopped working and the speedometer malfunctioned showing incorrect speeds at different times, including showing 80mph when sitting still in the driveway. Now the instrument panel has malfunctioned again. Now my battery gauge, fuel gauge, oil pressure gauge, and temp gauge stopped working and and are at zero as if the car is off. Most of my warning lights are on also. The ABS, seatbelt, battery, and parking brake lights stay on. Also, the gear indicator light telling me if I am in p,r,n,d, etc no longer highlights the gear I am in and the cruise control light doesn't come on when I engage the cruise control. However, I would say once out of every 15-20 times I drive the car the instrument panel and gauges work flawlessly. Obviously this time it is not the motors of the gauges that are the problem, but something power and/or electrical. I'm worried about knowing how much gas I have left and, more importantly, what my speed is, whether the engine temp is ok, and whether the oil pressure is normal.

While using cruise control at highway speed the speedometer erratically increases. Braking to a stop does not take the speedometer to zero. Turning the vehicle off and restarting sometimes puts the speedometer needle to zero in five mile increments with each cycle. Problem is recurring. Vehicle is taken to the dealer and a "cluster" problem is diagnosed with estimated cost to be around $500. Internet research reveals this to be more than a sporadic problem resulting in the manufacturer recalling a number of vehicle models but not the trailblazer. A call to gm's customer service department culminates only with a formal complaint being registered ... This too being the common end for owners of trailblazers (according to internet research) the problem is a potential safety hazard as when this occurs without warning one has to gauge driving speed by surrounding traffic.

I was driving at highway speed (approximately 65mph) with the cruise control set, when my vehicle suddenly responded like I had slammed the gas pedal down to the floor. My speed climbed rapidly, but I had the presence of mind to drop the truck into neutral (the tachometer continued to be at its maximum level and the engine still whined high) and steer to safety, across several lanes of traffic, to the breakdown lane. When I shut the vehicle off and turned it back on again, this issue was no longer present.

While driving along my tachometer and speedometer on my 2004 chevy trailblazer dip below zero. I took it to my mechanic who said the electrical is shot in the dashboard area. My vehicle has to be running for 30 min or more for it to act up. If I leave cruise control on the needle stays ,once cruise is turned off I'm doing (hopefully) 70 while my speedometer says I'm doing 20. Searching on the internet I'm not the first to complain about this. Has chevy recalled the dashboard unit in the 2004 trailblazer yet?

The instrument cluster in my 2004 chevy trailblazer functions erratically if at all. This behavior began a few weeks ago when the tach went crazy and eventually just quit, the needle now just sits at the bottom of the instrument and wiggles occasionally. The speedometer is erratic in that at times it will just quit and read o -10 MPH when I know I am going a lot faster than that (freeway speeds). The cruise control is so unpredictable I don't dare use it anymore. It speeds up for no apparent reason and I am afraid I won't be able to turn it off. What can be done about these issues. All in all otherwise we like the vehicle but the problems with the instrument panel are making us think about getting rid of it.

I own a 2004 trailbrazer that have the same problem as the gm recall on lose brake-lamp function or have brake lamps that are always on. On vehicles with cruise control, that function also becomes inoperative. . The federal safety agency contacted gm to inquire about the issue after receiving three complaints, and the company issued the recall in response, adler said.

Dt: 2004 chevrolet, trail blazer. The cruise control does not work properly. The cruise control does not stop the vehicle from increasing in speed when going down an incline. The consumer took the vehicle to the dealer who said that there was nothing they could do to fix this problem. When the consumer contacted gmc, they said that it was normal and it was designed that way to save fuel. *ak gm also informed the consumer to use lower gears when going down hill. The mileage would still increase when in third gear. *sc
