I noticed around March 18th 2021,that my headlights was out while driving and just 2 days ago my battery died April 12th 2021 due to my ignition switch being stuck it was parked already in my garage.
Headlights went off on three different occasions this past week, it also happened once before several months back. They just shut off and while your panicking and hitting the headlight switch several times they finally come back on. We will not drive it at night anymore. Why is my car not recalled when others from the same year are. I have been working in manufacturing for over thirty years and my dad worked on the gm assembly line for thirty years. Don't kid yourself that you know which batch of parts were used on a particular car. My VIN is defective.
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. .
I just bought this vehicle. The headlights won't come on the low beams. I pulled the blinker handle back for high beams to come on. I hold it back while I mess with headlight switch finally low beams comes on and I can push blinker handle forward to engage high beams to stay on.

Low headlights (both) are off continuually. High beams are ok, no matter which position dash headlight switch is in. High beams come on with steering column control, but not low beams. Replaced relays and fuses although originals checked ok. . Removed each headlight nacell assembly and checked each light individually with separate source 12v. All ok. Meter checked hi-lo headlight plug, 12v ok on hi wires, no voltage on lo wires. Problem exist whether car is running or not. I am stumped!.
Solid state relay module for low beam - high beam headlights. When driving at night, both low beam headlights went out at the same time. Was able to switch to high beams to continue home, but not without blinding other vehicles. Replaced the solid state relay at a local autozone store. This relay is a single point failure, which an un-experienced driver could have had a possible accident if the person did not know what to do quickly in a calm manner.
At approximately 9:00 pm I was traveling on a rural road at highway speeds and suddenly my headlights went out. The headlamps were on low-beam at the time. I checked the headlight switch and it was in the proper position. I switched the headlights to high-beam and the lights came back on. I researched the issue and it appears that a 'headlight driver module' is to blame. This module appears to be a significant source of failure. This is a terrible design flaw. Something as important as headlights should not be subject to such a poor quality device. I would like to see no devices between the battery and the headlight switch and the headlight switch and the lights.
Headlamps failed while driving. Driver switched from high beam headlights to low beams. Nearly crashed when low beam lights failed to work. All other lamps functioning properly. After stopping, driver tried to switch the lights on and still failed. Only high beam lamps functioning. Vehicle can no longer be driven at night. I have been registered owner of this vehicle for past 5 years and was not notified of this recall by gm.
After leaving a movie theatre and upon entering the freeway June 13, 2015 at 12:30am, it appeared that the headlights were not on. I drove the vehicle, (with the high beams on) to the first available exit to pull over and found the headlights were not on and would not come on. I turned light switch on and off, turned the vehicle on and off and tried light switches again - this did not resolve problem. The high beams were still working. After leaving the high beams on for a while and trying the headlights again, they came back on. Approximately 2 months later, on August 8, 2015 while driving to the store, the headlights were not working again. I pulled the vehicle over tried the switch, tried turning the car on and off, again this did not resolve the issue. After driving with the high beams for about 5 minutes, I tried the headlights again and they came on. The same problem occurred two more times in the same week on August 11th and 12th, 2015 while driving at night.
I was driving home one night about an hour after dark. As I was driving about 45 mph, my headlights just completely went out without warning. After carefully pulling off to the side of the road I realized my high beams were still working. I looked into this issue and realized it was a relay 45 and 46 issue. The next day I replaced this relay and my lights worked. For a day. Now it's been almost a month, and I can't drive after dark. I've asked my local gm dealership to look into this and they told me there was a recall but yet they don't have a resolution. Being I work until the sun goes down, and I have an hour drive home from work 5-6 days a week, this presents a major problem for me. If this were a simple window switch recall (which I've already had replaced) I would be ok with it for now. Unfortunately this is a lighting issue which can be and is a very serious issue. I need this issue resolved immidiatly and if the dealership can't fix it, I don't know how I would be expected to.
The contact owns a 2007 Chevrolet Trailblazer. The contact stated that while driving at approximately 55 mph, the headlights flickered. The vehicle was taken to a dealer where it was diagnosed that the relay switch needed to be replaced. The vehicle was repaired. The manufacturer was notified of the failure. The approximate failure mileage was 129,000.
Approximately 2 years ago my dim headlights went out as I was driving at night. I thought to switch to high beams and luckily they worked on high beam thank goodness this was a road I knew well. . I have no way of knowing how often this happens during the daytime. But it occurred several times after this. I had my vehicle checked and was told it was a relay. Changed it and problem solved, until now. The issue is back, gm sent me a "special coverage" letter, I called the number on the letter and was directed to take it to a chev. Dealership to confirm my vehicle does have the headlamp driver module issue then Chevrolet will let me know what would be next. They did confirm my vehicle has the issue but Chevrolet will not cover my vehicle because it is over the mileage of 150,000. Really? is my vehicle no longer worth fixing or is the issue supposed to resolve itself after the 150,000 mile mark? a salesman called me after I left the dealership to ask about me trading or getting rid of my vehicle, is this a ploy just to sell vehicles?.
