Chevrolet Trailblazer owners have reported 23 problems related to cruise control (under the vehicle speed control category). The most recently reported issues are listed below.
While highway driving with cruise control engaged I heard a loud whining sound and experienced a sudden loss of power. I was almost hit from behind several times before I could get the vehicle over into the right lane. When I took the vehicle to my mechanic I was told the cooling fan clutch assemble had failed. I have had this fan replaced three times now and am not at all pleased that this vehicle has not been recalled for this problem. I have read that this is a "common" problem on this vehicle that can cause a severe accident. I have receipts for the repairs but have no way to upload them.

This issue occurred about 6-7 times throughout my 15 mile trip. My travel was on a highway and speeds were between 55-68 m. P. H. At the onset of each occurrence. I would hit a bump in the road (not a major one ¿ just a bump) and then the ¿stabilitrak active¿ light would be illuminated in the dash continuously blinking like it's stuck. Then: -the truck would become sluggish dropping speed and knocking off the cruise control -you can¿t accelerate -the steering locks up sort of causing it to feel like the truck is out of control, this occurring at highway speeds -the amount of power used by stabilitrak was immense ¿ the headlights began to dim the longer it was stuck in this state -if you try braking during these spells it has the anti-lock active so you¿re just grinding away like you¿re in a skid but not stopping (and this is on dry pavement!) -- this occurred one time while I was on an exit ramp and and I was unable to slow thankfully I had taken the ramp a little slower to begin with or I could have been in major trouble in the curve then suddenly as quick as it all started it releases ¿ the light shuts off and all returns to normal.

I bought this car at the end of March of this year with under 100,000 miles. The first thing to go was the gas gauge, about 2 months after I bought the trail blazer the needle went south. It actually hovers around 6 0 ' clock. Then a couple nights ago driving home I had the cruise control on, I took it with the hand button and looked down and the needle never moved, it was stuck at 65. It's been 3 days and the needle has moved but the wrong way, to the right going up 75, 80, 90, then back down to 65 and staying there. I have looked into replacing the gas gauge and I was told the entire dash would have to be done at a price of 1200. 00, I should not have to do this, Chevrolet should be held responsible.

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.

While driving to work my cruise control shut down and my speedometer stopped working. A couple weeks later the speedometer began working and now it has stopped again and stuck on 55 and doesn't move regardless if the vehicle is on or off. The cruise control won't work. I am very frightened to continue driving without knowing what speed I am driving. I can't afford to keep spending money on this vehicle to repair all the problems it's had. Wondering if the speedometer is covered under my 100,000 mile warranty. Please help.
The speedometer is not registering the correct speed, jumps around while driving and has affected the cruise control. I found that this issue is the same as nthsa item # 10023585 for most similar gm vehicles, but for some reason, this family of gm trucks was not included in the reported issue. When the vehicle is stopped, the speedometer needle drops well below 0 and then jumps around when the vehicle starts moving. Based on checks with our gps, the speedometer is off by as much as 20 mph.
Speedometer goes completely out, falling below zero while traveling on road, typically after cruise control has been used, multiple warning lights flash while onstar and computer showing no codes after 4x4 used. Unable to diagnose problems because problem is intermittant and after vehicle parked for several hours problem is gone. Occurs about once a week. Has caused several instances of being unable to determine how fast your traveling. 2004 chevy Trailblazer ext lt 4x4 i6 engine.
My wife was driving our vehicle with our two children in the car. She was traveling at highway speed with the cruise control set when the speedometer of our vehicle faulted. It started showing she was going 110 then 20mph then 50mph and so on and so on. She pulled over, phoned me and we called our insurance company to see if towing could be provided. It would have taken over 2hrs for towing assistance so she traveled the rest of the trip (approx 105miles) following another vehicle in hopes that they were traveling at a safe speed. The following day I research this issue, brougth my vehicle to a dealership and they explained it was a known issue with a 05 Trailblazer and the gm had a class action law suit for replacement of this part they state the instrument panel needed to be replaced. However, we later found out that our vehicle was not part of this litigation and we were stuck paying the bill. Not only does gm know this is a safety issue, they are unwilling to compensate or take corrective action for their customers. Needless to say I am very upset and frustrated for the safety of my family and the fact the gm has not offered any remorse.
Bought this vehicle used in oct 2010. Not long thereafter, noticed the speedometer wouldn't work all the time - normally it works when I first start driving but when the vehicle warms up, it stops working all together. I think it's a safety issue if you do not know how fast you are going. The cruise control also doesn't work once in a while. Most of the time it does, but occasionally I can't get it to go on at all.
My vehicle is currently at 116,000 miles and the speedometer and tachometer all of a sudden went to zero. It continued to stay at zero after I turned the vehicle off. The next time I drove it, it stayed at zero until halfway through my drive when now its stuck at 61 mph, which is where my cruise control was set. The tach now works half the time but the speedometer is giving me misleading information. I live in wisconsin where the weather is such a variable. I am always using my speedometer in certain road conditions. I have certain speeds I go in certain conditions (light snow, deeper snow, rain to freezing rain, freezing rain, slushy conditions, ice, sleet and just plain normal. ) consequences for not retaining the correct speeds in certain conditions in wisconsin. . . . Gee let me think. . . . Death would probably be the worst. Nothing's been done to fix this yet because I cannot afford it. It's one of those things that should just work and its a damn shame gm hasn't done anything yet considering all the problems.
I purchased a 2003 chevy Trailblazer one year ago with 63k miles. At 85k miles, the speedometer quit working. Most often, the vehicle defect occurs when the vehicle is in cruise control mode. However, once cruise control is turned off, the defect persists. Even when the car is completely turned off, with the key removed from the ignition, then restarted, the defect persists. There are two types of situations when this problem occurs:
1) the speedometer registers a speed, but it is rougly 15mph less than the vehicles actual speed. This, of course, is quite dangerous if the owner of the vehicle does not know about the defect, for example, if it is happening for the first time. It can be costly to the pocketbook, driving record, and potentially deadly. 2) the car is driving, but the speedometer registers 0mph. When I first noticed the problem, I was driving on a highway. I have a gps feature that allows me to detect speed (thankfully) and accelerated to 80pmh for a brief period of time, but the speedometer still registered 0mph. After doing some research on the internet, I realized this was an extremely common problem, not just with chevy Trailblazers, but with a whole host of other gm vehicles. Additionally, those making reports claimed they had sought other outlets of repair, many of them costly, all of them to no avail. Each customer complained that gm was in no way helpful and had no intention of recalling vehicles, despite the fact that this is a common and dangerous defect. Upon further research, I discovered there was a small settlement concerning the issue, thus suggesting that gm acknowledges responsibility for the defect. However, the settlement only covers a small number of vehicles, and to date, no recall has been issued for this problem. I have personally contacted Chevrolet and am awaiting a reply. Additionally, I plan to take my vehicle into the dealership, but as I am in the military, I must wait until my schedule allows.

I, along with many others are experiencing major problems with the instrument panels on our Chevrolet Trailblazer. My mother traded hers in because her speedometer was going out. But my problem is much worse, my whole entire dashboard is out. My gas gauge doesn't work, my speedometer doesn't work, my oil pressure doesn't work, my thermostat doesn't work, nothing works. My cruise control acts up too.
Cruise control on 2005 Trailblazer when the resume is pushed it will go wide open until it gets back to speed ,which could cause a crash if it was unexpected.
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.
No cruise control indicator lamp on dash board. This becomes a problem because you do not know when the cruise control is active or not, which can create an accident when letting off the gas to start to decelerate.

Speedometer went haywire on a 450 mile trip got about 200 miles and the speedometer read 90 mph when cruise control was set at 79 mph. Went to get off of exit and when I stopped it didn't go back to 0 instead when I started driving again it went below 120 and was hanging directly down. We got it back down to zero by having to start it and turn it off 5 miles at a time. It has happened 3 times now in less than a week.
Cruise control shut down. It was set at 70 mph. Vehicle was going uphill and it felt like the engine had died. The speed drop was sudden and drastic, luckily there were no vehicles following when it occurred. It would not resume nor reset by turning cruise control switch off and on. Vehicle did accelerate using foot pedal. Started vehicle up next day to take it to dealer and the cruise control worked fine. Contacted dealer and was told he never heard of this problem before and maybe it was just a fluke happening.
With cruise control set going down hill. The vehicle doesn't hold the speed you set it at. Depending on the size of the hill it will gain between 5 and 15 mph.
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. Gm also informed the consumer to use lower gears when going down hill. The mileage would still increase when in third gear.
The consumer experienced a bucking problem when using the cruise control option. The fuel supply seemed to be intermittent. Chevrolet advised the consumer that this was the normal condition.
I have a 2004 trail blazer ext. At about 2200 miles the cruise control stopped working, and when I got an appointment to take it in, they told me, that in fact it wasn't an issue with the cruise control, that there had been a short in the torque control converter solonoid which was a problem with the engine. They had a part overnighted to alderman's Chevrolet, who fixed it quickly and made sure I had a rental while it was in being fixed, but a week and a half later, the same thing happened again. I am taking it in tomorrow, but I am afraid there is going to be permanant damage to my engine because this thing when broken affects the shifting of the engine. I am wondering if I just got a lemon or if this is a common problem with these vehicles. It only has 3500 miles on it, it shouldn't be in the shop twice already for repairs.
While cruise control is engaged, engine stutters after cresting a hill, more or less coasting down the other side.
We have a 2002 chev. Trailblazer ext. This vehicle's cruise control cuts out while it is set. It has happened numerous times - too many to count - and at different speeds depending on the state and speed limit. The cruise light does go on when it is originally set but goes off at random and with truck traffic behind you it is not a place where you want to be slowing down and not realizing it immediately.
