Within 3 months of owning the vehicle I started to hear a crackling sound coming from the passenger speaker in the door. At first it was loud and I thought someone hit me. It did it several times and then stopped. It has happened about a dozen times since I have owned the vehicle. When I took it in for my oil change I told them and they could not replicate it so they didn't know what it was and didn't see anything. It actually just happened again yesterday so when I take it in again I will tell them about this. We thought maybe it was onl…

WHEN YOU SHIFT TO PARK A MESSAGE COMES UP AND SAYS SHIFT TOPARK WHEN IT IS ALREADY IN PARK. THE MAIN PROBLEM IS THE VEHICHCLE WILL NOT SHUT OFF. YOU HAVE TO DO MANY DIFFERANT THINGS TO TRY TO GET THE MESSAGE TO LEAVE AND THEN IT WILL CUT OFF. THIS HAS BEEN HAPPENING NOW SINCE IT HIT 29700 MILES AND DOES IT ALMOST EVERYTIME WE DRIVE IT NOW. THERE IS A SERIOUS PROBLEM HERE IF YOU CANT SHUT OFF THE VEHICLE . I ALSO NOTICED MANY OTHER PEOPLE HAVING THE SAME ISSUE WITH THE TRAILBLAZERS. THIS NEEDS A RECALL FIX.

My brand new two week old 2026 Chevrolet Trailblazer LS Issue: Auto Start/Stop system failure, the engine shuts off and does not restart Description:
 While stopped at traffic lights with the auto start/stop feature engaged, the engine shuts off as designed. However, when I release the brake pedal, the engine does not restart as it should. Instead, the vehicle displays a message stating “press brake to start,” and the vehicle behaves as if it has been completely turned off. This leaves the vehicle temporarily disabled in traffic and unable to…

WHEN IT IS DARK OUTSIDE AND YOU PUT THE VEHICLE IN REVERSE, THE LIGHTS NEXT TO THE BACK UP CAMERA CAUSES THE SCREEN INSIDE THE CAR TO SHOW BRIGHT WHITE. THERE IS NO WAY TO SHUT THE SCREEN OFF WHEN IN REVERSE. I HAVE TURNED THE BRIGHTNESS ALL THE WAY DOWN BUT IT IS STILL VERY BRIGHT MAKING IT IMPOSSIBLE TO SEE YOUR SURROUNDINGS SAFELY. I HAVE ALMOST HIT A TREE AND DROVE INTO A DITCH TRYING TO REVERSE AT DARK. THIS IS VERY DANGEROUS AND NEEDS TO BE FIXED.

I had a smell of gasoline inside and under hood of 2021 Trailblazer LT 1.3l. Took to Chevrolet dealer.Confirmed gas odor. Gas was leaking from fuel rail.Sevice manager said it was pouring out. Found out GM has Service bulliten for this PIP5765 that covers both Chevy Trailblazer with 1.3l and Buick Encore GX with 1.3l motors.

My 2023 Chevrolet Trailblazer is about 3 months old and it’s been making squeaky noises when I break. The squeaky sound is getting worse over time and I have an appointment scheduled with Chevrolet to get this resolved. My concern is a 2022 recall on this same vehicle due to the break system. Therefore, I am reporting this for the year or 2023 because my car is brand new and making screech noises every time I break. Also, my electric system randomly stops working.

I have noticed that when it's very cold, the vehicle will not shift to the two highest gears (I think) until 20+ minutes into my trip, and that's with having auto-started the vehicle 10 minutes prior to getting in it. So it takes about 30 minutes for the vehicle to shift into whatever the two highest (I think) gears are. This morning, 20+ minutes into my trip, I was going 71mph while pushing 4,000rpms, and it wouldn't shift. The temperature outside is 1 degree fahrenheit.

My vehicle was struck on the left front drivers side while traveling 55 mph. My car flipped multiple times, but when it came to a rest on the drivers side, my head was trapped between the driver's window and the side curtain airbag. I couldn't move the airbag, so I had to move my seat back and bend my neck/head back and down out to get free. My face/head/neck/upper shoulder suffered bruising on the RIGHT SIDE of my body from impact of the airbag.

Emerging complaint spikes

Complete months in the latest six months with at least 10 complaints, at least twice the preceding 12-month average, and at least three square-root deviations above that average.

This is a descriptive screening rule, not a statistical defect finding. Publicity and reporting changes can increase submissions.

No complete months meet the spike thresholds for this selection.

Equal-age model-year comparison

Model-wide cumulative reports during the first three or five calendar years, starting with the model year (age 0). Only fully elapsed windows are compared.

Incident date is preferred when valid and no later than filing; otherwise filing date is used. Model year approximates age. Equal observation time does not adjust for sales, distance driven or reporting delays. One complaint linked to multiple model years can appear in each cohort.
