Melissa Manley: We have an 2005 trailblazer that we bought used. We have had it for 5 years now and have almost hit 200,000 miles on it. The only thing it's been in the shop for is brake pads and oil changes. Sometimes but very rarely the speedometer will stick but it fixes it self! It's awesome on gas we get 28mpg on the highway and 18mpg in town!! Which everyone is amazed about lol!! I'm actually very shocked to hear these problems because ours has been beyond the best vehicle we have ever owned!! We are actually looking to get a newer trailblazer because this one has been so great!! Sorry to hear these issues though!!
jo jo: I have a spreadsheet going with ALL of my issues. None of them cheap. Also a '05.
S Hoffman: Mine does the same thing!! And now my AC blower comes on by itself when the vehicle is off and no key in the ignition
spitfire: I have an 04 TB EXT LT with 239k on it. Has been a great truck. I've replaced water pump, alternator, rear wheel bearing, sway bar end links all around, along with upper & lower control arms. Serviced transmission & transfer case, tires, and normal tune up maintenance. I have been hard on this truck and pushed it beyond its limits. Towing heavy trailers throughout colorado mountains. Several cross country trips. Truck has never left me stranded or without a ride. Guess I'm one of lucky ones.
gina pender: I have major issues with my 2005 Trailblazer. Cost of repairs are crazy!!! I took mine to have general maintenance done and have to replace the clutch fan which will cost me over $600 along with the air pump replacement cost of $557. My check engine light stays on and the gas gauge doe not work! This winter I had to have some electrical work done because wires fried that operated my heater blower fan which costed $500. I thought I was getting a good deal when I purchased this vehicle with low mileage. Lesson learned.!!!!
JOYCE “Glenn'sSis” CLEMONS:
ALL I HAD TO DO WAS CUT N PASTE FROM ANOTHER PERSON ON THIS THREAD... Electrical system, on going. Check engine light, ha ha, it's normal. Fix the check engine light, reset it, fine for a couple months or so. Bam! Back on. Instrument cluster, (ESP SPEED, TEMP) flaky...sometimes works, usually not. . pt CRUISE, WHEN IT FEELS LIKE IT. Today, it wouldn't go in reverse. So now we are looking into diagnosing the transmission control module, we have read some weird things that will do. Possibly will do a try at rebooting that.
Found that part which would cost 102 from Whitney if the first trick doesn't work
I kept the link to this...if we learn more, will be back.
PS I'm a 63 yr old clueless widow but I got a tip from a friend. Can't check these tips out until my son gets in from out of town next week. He's "the man" at keeping me on the road, but it's a headache. Will be driving my 94 Cutlass until he gets home, and maybe for a while after that, if this gets complicated. Cheers! PS otherwise it's a nice ride...lol
WOODARICH: Yep! 2005 Trailblazer, full of issues since the wife drove off the lot within 2 weeks. Transmission, warranty, had to fight for it. Electrical system, on going. Even the tail light bulb melted and had to replace the entire tail light assembly instead of bulb. Check engine light, ha ha, it's normal. Fix the check engine light, reset it, fine for a couple months or so. Bam! Back on. Nickel and dime is an understatement. What we have paid to get it checked and fixed, we should have just traded it in for another vehicle. Chevy customer service sucks, will never deal with Chevy again. Chevy should have recalled alot of their vehicles. Oh well. Good luck to the rest of you Chevy owners.
wilton bravo: Q problema ase y cuanto cuestala canbiada del sensor p0014
Kyle S: 2005 suburban speedo stuck at 70 when parked, sucks!
Jimmy Hinton (pudgybear100): I replace my stepper motors in my 05 Trailblazer and I haven't no problems yet. I think I paid 30 bucks and 2 hours time I was back on the road. That has been about 3 years ago.
Ellen Lowrimore: Yes .. I think there should be recalls .. 2003 gas , rpm , oil are off too .. I have to guess on the gas amount .. Love my ride but it is annoying .. 300$ !? Ouch
Armani Blake: i HAVE A 03 LTZ TARILBLAZER AN MY DASH WONT READ CANT C HOW MUCH GAS OR TEMP GAGUES WONT READ ANYBODY CAN HAELP??
***Classified***: Modern Chevy's suck.
christina bednar: ohh, boy do i have issues, im so sick of it,i still owe on my 05 for another 2 and a half years, i took it in last year to get the 4 wheel drive fixed, never used it after the shop and gues what, its messed up again, my service light has been on for over a year, now theres something wrong with the exaust,the gas gauge doesnt work most of the time, i recieved a letter from chevy,but they said its at my decresion to fix it,it has been one thing after another , i was forced to buy this insurance but everything that had to be serviced, the insurance doesnt cover, i swear i will never buy a trailbreaker again, ughhhh
Scott Dowen: Doug change temp sending unit.
Douglas Chapman: check engine light is not on.
Douglas Chapman: I have a 2005 TB and the temp gage is moody.After I had a new water pump and thermostat replaced my gage was fluctuating instead of staying at 210.last few weeks its been at 210,whats up with this.The thermostat is a carquest and not a GM Delco.
DanielRichards644: no need to pay 300 bucks for a cluster, just replace the stepper motors it's like 30 bucks to buy the stepper motors and do the work yourself.
Cody Shayna: i own a 2005 chevy trailblazer and within the last 2 months my instruments have began to malfunction. it started out with oil pressure gauge which has since fixed itself. now its my rpm gauge it messes up from time to time.
vchavez75: Follow-up from Vchavez75: I bought by TB 2005 brand new and experience every electrical issue described by all plus I rebult the tranny at 125K! Oh well!
