My vehicle shows gauge light as empty even after filling up. My vehicle stopped in middle off road on early morning traffic. Now we have to estimate mileage to make sure we are not left without gas, very frustrating and unsafe but can't afford to fix.

Ran out of fuel once on highway, when gauge showed tank was full. In Jan/Feb the gas gauge just stopped working even when completely full of fuel it will show only 1/4 of a tank or none at all. The radio works only intermittently will work then stop working unexpectedly. Headlights are always burning their connection, short circuiting my headlights pretty frequently.

Fuel sensor seems to be failing as is with many other problems with the electrical system on this car including a broken speedometer at 60,000 miles. This car seems to have far too many sensor or electrical issues and given the safety implications of speedometers that suddenly fail and fuel sensors that fail, it would seem prudent for someone to realize that these issues pose a severe safety hazard to all. After research on the internet, speedometers and fuel sensors seem to be a common issue with Trailblazers. Please research the electrical system and sensors more closely.

While driving it appears that my headlights are receiving a surge of power which causes them to blink as if I am flashing my headlights. This has happened on and off for a couple of years now. Since this has started I have had to replace my headlights about every 6 to 8 months. After the third time I replaced the same headlight my mechanic showed me the fuse and stated that it seems there is a surge of power that causes the fuses to blow. I explained to him that my headlights seem to blink on their own every now and then and we did some research online and noticed that this seems to be a common problem in mid 2000 model Trailblazers. I contacted GM to make them aware with nothing more than a, "sorry for your inconvenience". I have also experienced issues with my door electronics. You can hear the power windows and door locks make a clicking sound as if they are being engaged without being operated. The speakers in the doors do not work after it rains or in very humid conditions. The power windows and door lock button lights work on and off and blink. The door/key chime rarely works. It seems to me that there is a serious issue regarding the electrical system of this model. I recently heard about the recall starting with 2006 models with electrical issues and I really believe this problem is not just isolated to the electronics in the door, but the overall electrical system in these vehicles. Considering the amount of complaints I have researched online it seems that these are common problems with these vehicles. Please for the safety of the consumers consider an investigation and recall into the full electrical system of this vehicle as it could be a serious safety hazard risking fire.

My speedometer tells the speed plus or minus 40mph. My oil pressure gauge is stuck at around 210psi. Today, I noticed that my fuel tank now reads 150% full, and the voltage is down to 9V. This is all due to a defective instrument cluster that GM had a class action suit filed on several other makes of vehicles, but denied the Trailblazer, due to lack of complaints. Consider this a complaint. Undoubtedly, GM is hoping the mileage runs over 70,000 so I will have to pay at least part of their defective workmanship. Consider how many Trailblazers are zipping down the road, unaware of this defect... perhaps going only 10-20 mph over the limit. Lack of complaints to the NHTSA is a poor excuse to not recall, fix and/or verify the vehicle in question is not an issue. I am currently using a gps smartphone as a speedometer, but as you can imagine, it is less accurate than ideal. A young friend housesitting my dog drove my car once, on a bad snow day, and got a speeding ticket, as he was unaware that the problem existed. I suggest GM be made to fix it.

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.

- Oran, MO, USA

Even if this car is well maintained it sadly as serious electrical issues that Chevy does not want to come to terms with. The speedometer goes out and in and reads incorrectly as well as the rest of the gauges at random points in time. The heating system needs replaces and the alternator consistently needs to be replaced even when the maintenance of the car is maintained. It is a consistent struggle to keep the car running even if it is not on high miles and it is a sad product for Chevy.

2005 Chevrolet Trailblazer. Consumer writes in regards to vehicle fuel gauge sensor issues. The consumer state the first time the fuel gauge starting acting erratic was in 2007. The dealer informed his wife, the vehicle had ran out of gas, even though the gauge indicated there was 1/2 tank of gas. The consumer stated he continues to experience an erratic behavior of the fuel pump and the low fuel indicator light illuminated. The latest preliminary diagnosis was the vehicle was unable to sustain an idle, because of the erratic fuel pressure (fuel pump). The consumer also stated the vehicle has electrical problems and the oil pressure gauge was inoperative.

The fuel gauge in my vehicle stopped working. I did some research and this seems like a common problem to Trailblazers that GM is ignoring. Running out of fuel can be very dangerous especially on busy highways. So I think this should be a safety issue that needs to be addressed as soon as possible.

- Eugene, OR, USA

Purchased 11/24/2008 ~20K miles. Within 5months a whole host of issues started, the 1st being the fuel gauge not working by showing full & actually not (ran out of gas twice) and then showing empty after fillup. 1week later the engine light came on & the instrument panel stopped working. ~ one year later, Dec 2009 the speedometer fluctuated from working properly to ~50-55mph base instead of 0. after a few days, the speedometer did zero-out but then did not show any speed but stayed at 0. along with the speedometer issue are the headlights dimming sporadically. All of the issues have continued on-off since. March 2012 the windshield reservoir started leaking/cracked. February 2013 had tuneup, brakes, and thermostat replaced and since then add front vents stopped working plus severe, sporadic, high idle - driving to work (metropolitan, downtown, capital of state-high rush hour) the high rev started and all I wanted was to get to workplace parking lot ~2miles. 2blcks fr pkg lot, I was braking at a left, dblturn light with the rev & brakes grabbingh/counteracting. I come to a full stop but my SUV revs to over 3rpms & I thought the trblzr would break free & crash into the cars in front of me! I have a "christine" car and hate the feeling of driving an unsafe vehicle that Chevy won't recall/fix and I can't afford to buy anything else currently or get all these issues repaired. I place mine, my kids and passengers' lives & safety into jeopardy every time we get in to drive/ride. I only have 78K miles and 1yr of car pymnts left. I will never buy another Chevy again and I was a diehard Chevy and "buy american" consumer. This vehicle is a piece of junk. My next purchase will be any vehicle that is safe, whoever the manufacturer may be. Can anything be done to help"?"

I had just filled up my SUV, and while on the highway, my fuel gauge started dropping within a minutes time, to 3/4 tank, 1/2 tank, 1/4 tank, then the fuel light came on and stated I was on empty. I didn't smell gasoline, but the gauge then started going back up, then down and went haywire. After some of the gas was used, it went back up to almost full, but after a bit, it dropped back down to half tank again. Every subsequent time I fill up, the gauge does the same thing. Another incident that has been happening for the last few years is the head lights dim and get brighter. This doesn't happen all the time, but at least three times a week. I didn't think too much about it until I saw other complaints on this website about the same thing.

I purchased my '05 Trailblazer new off the lot never had any problems until the speed odometer stopped working. Couple years later my oil & gas gage stopped working. I based my speed off my RPM & calculate my gas mileage after each fill up. Now my dashboard lights are dimming & I've noticed on many occasions my headlights flicker...I have replaced the battery twice & the water pump twice. Now when my check engine light or this other little chk gage light comes on, I don't know if a malfunction of if something is truly wrong. Now it's running rough, acts as if it wants to cut off. They have checked all that they can but because the chk engine light isn't on, there's no way for them to identify the problem. And unfortunately, when the mechanic rides with me of course the car won't do it...and although, these are separate issues I can't wonder if replacing the battery is connected the same system as the dashboard. I've been told by 2 differ mechanics it would cost up to $600 to replace the whole system. But after reading all the complaints, many having the same issue as me I can't help but wonder if this problem could or should be on a recall & if not, why? if you view the complaints why not look into the very present & persistent problem! its very frustrating & aggravating to play a guessing game when your up & down a highway daily! not to mention a safety hazard! surely, your company isn't so money hungry that you can't take responsibility for you product & offer to pay for some or all the costs to repair! I'm a single mother of 3 & I was blessed enough to pay my car off a year ago but I've paid more in repair costs & stressing whether or not I'll make it safely to & from my destination! I never had this many issues with my grand Jeep Cherokee. I am truly disappointed in your vehicle...

My speedometer started to go crazy jumping around while on the highway it started off reading fine then all of the sudden it read that I was going 120mph by the time I got home it did not work at all had to guess my speed then about a two weeks later it started to work again same day it went haywire again and now it does not work at all. Also I have been having problems with battery draining I have been to several places to get it check out all that can be found out is that something is staying on while the car is in the off position. There are times when I have to jump my car several times in a day and there are times when I can go days, weeks without the problem just never know when it is going to happen.

Vehicle would not start. Had it towed to mechanic shop. Battery was completely dead, though the battery was only 1 year old and was a very expensive ac delco 6 yr battery. Mechanic changed the alternator and the battery and everything tested the same. Put old battery and alternator back in, as battery he charged was holding the charge ok. Could not locate source of problem. The next day, the dash lights were not working, nor the interior lights. As I drove along the highway, the dashlights blinked and then stayed on. Ceiling light works intermittently. The alternator shows that it is charging very hard. According to other incidents reported on the internet, there is an electrical problem in the 2005 Trailblazer that may or may not be associated with the passlock anti-theft system, but in any case, shows slow leak of electrical current that slowly drains the battery 24/7, until the battery is dead. Why is no recall issued making General Motors responsible to find and fix this problem without cost to the owners of 2005 Trailblazers. I spent $130 at the mechanic shop and they could not find what the problem is, much less fix it. My vehicle is parked in a garage most of the time, and there is no reason for this malfunction other than faulty GM part somewhere. Our local Chevy dealer told me they think the problem is related to the passlock anti-theft system but they have never been able to nail it down. They reference a vehicle which they kept for two weeks for diagnosis of a "won't start" complaint, and the vehicle started some days and not other days with no pattern to the malfunction.

The oil pressure gauge stopped working. Second incident at a later date, the speedometer stopped working correctly, third incident at a different time, the fuel gauge reads incorrectly, fourth incident, the battery gauge is working sporadically. Most of the time the gauges do not function properly or not at all.
