Recently reported ELECTRICAL SYSTEM problems on 2007 Chevrolet TrailBlazer

The speedometer keeps malfunctioning. the speedometer needle sticks at a higher speed after decelerating or stopping, making it impossible to know what speed you are driving. this happens mostly when the weather warms up, spring/summer/fall. making a hard braking stop, like at an intersection, will sometimes cause the needle to drop back 5-10 mph, as will turning the car off and back on. most specifically, yesterday, may 31, 2019, the speedometer needle wouldn't go back down at all, and my speedometer was "pegged" past the top end of 110mph. i have researched online, and this seems to be a common and chronic issue with this model.

When driving the vehicle the headlights will just randomly go out.or at times they will go out come on and go out again..."while driving " especially at night" causing me to having to pull over..unable seeing where im pullin off the road to.after several tries of turning switch on and off..the lights return.but only for a few and then it does it all over again.this happens randomly..reported it to yhe dealership whr i purchased it...i was told they was unable..to see it.but had change the fuses..

All of sudden my tail gate will not open unless the vehicle is running and i hit the unlock button 5 or more times and then at times that doesn't work also my airbag light starting blinking and now it won't go off. i called about a recall and was told there wasn't one for this problem but on line it showed it was. my case number is 4864379595 i am going threw cancer treatments and need my vehicle please let me know if this is under recall as i can't pay right now to get it fixed.

Tl* the contact owns a 2007 chevrolet trailblazer. without warning, the low beam headlights failed to function properly. months later, the manufacturer sent an extended warranty campaign letter. the contact called the manufacturer and was informed that the vehicle exceeded the mileage limitation and they refused to repair the vehicle. a dealer had not inspected and diagnosed the vehicle. the contact was not provided with a solution from the manufacturer and was uncertain of when the vehicle would be repaired. the failure mileage was not available.

The driver side door electrical panel malfunctions and the door does not open and the window does not go down and the window lock unlocks after being locked. the rack and pinion had to be replaced twice. the car turned off while driving. the light in the back will not work no matter how many times the bulb and rack has been replaced.

With no warning, both headlights went out and no longer work. turn signals, fog lights still work.

My power window on the driver side recently quit working and i am driving around in freezing weather with the window open. i understand there was a recall #13v248000 on this issue. *tr

My low bean head lights stopped working. 2006/2007 trailblazers had a recall for the head light module. the dealership charged me for the repair. however, i'm told my car doesn't qualify for the recall. its the same make model and year.

My head lights and day time running lights will not turn on.

Driving as normal, when stopped at a stop light, rough idle to completly shutting off and throwing enine codes. this has happened multiple times and found out today that the fuse block is trashed.

Vehicle was parked for a few hours when went to start up to leave both low beam headlights/daytime running lights suddenly went out and have not come back on. fuses are good and bright lights work also low beam bulbs are good.

Tl* the contact owns a 2007 chevrolet trailblazer. the contact stated that there was an electrical short and the front passenger side low beam light failed to illuminate. the contact replaced the bulb, but the failure recurred. the second time, the front passenger and driver side low beam lights failed to illuminate. the vin was not included in nhtsa campaign number: 15v599000 (visibility). the manufacturer was notified of the failure and provided no remedy. the approximate failure mileage was 110,000.
