The Turbo is bad in the car at 90,000 miles. It is a common issue among these, lots of other people have the same issue with the “engine power is reduced” message popping up, per the 2021 Chevrolet TrailBlazer facebook group. There needs to be a recall so they can be fixed. It has happened on mine for the past few months and the dealer said the turbo is bad. The purge pump has already been replaced.

CHILD SEAT:VEHICLE LATCH ANCHOR
there are no tethering clips at the base of the rear seat to secure a child's car seat. The bottom of the rear seat shows they should be there but the dealer confirms they are not . This is an immediate and dangerous problem and puts any child in a car seat in a chevy trail blazer at risk. Not sure how I'm going to secure the granddaughter's car seat safely .

Tether, Lower Anchor (on car seat or vehicle)
My issue is with the vehicle's car seat latches. The latches in the Chevy Trailblazer (Manufactured) are designed in a way that is unsafe and also hard to install a car seat for children who are 2 and under or under 40 pounds. Car seat safety is important for all children as it could lead to damages of the head, neck, and or spine. I have installed 4 car seats in my vehicle (Chevy Trailblazer) with it being difficult but overcoming the problem. However, the car seat detaches itself due to the location of the latch (Vertically Slanted). After using the car seat multiple times, it cannot withstand the tension due to the location of the latch which then releases itself from the latch, potentially allowing for more problems to occur and is concerning for the safety of a child. I have, as of now, not have to deal with this problem with other manufacturers like Toyota, Kia, Tesla, Volkswagen, and Honda, where the latch is horizontal. The latch on GMs Vehicles is Vertically Slanted and located left or right of the manufacturers noted car seat latch display/button on the seat. I have only seen the Chevy Trailblazer (My Vehicle) and the GMC Yukon with this problem. I am sure there are others.

ENGINE
Whenever I accelerate over 65 miles per hour the engine and transmission light comes on and the car goes into reduced engine speed. I get a message to service my engine I took it to the dealership, they could not figure out the problem because the engine light only stays on for a day or so and then goes out again. This issue has been happening more frequently over the last few weeks.

WHEELS
Shortly after purchase, one of the factory tires had a side bulge. The dealer indicated in their opinion, was from a pot hole. However when they checked the rim, it was not damaged. I had tire replaced. Then at 39K miles, all the the other tires were already getting worn out. I've NEVER had tires wear about pre-40K miles in all my life. At local belle tire, they told me that the Hankook tires that come with new cars are not the same quality as those you would buy at tire store. But I submitted a replacement claim to Hankook, as the belle tire rep suggested, but they would not honor anything. Simply said need tire insurance. I notice when buying the car new, the dealers offer extra (cost) tire insurance. Must be because the are lousy, compared to buying at a local tire store. Now at 42K I'm replacing tires already. New cars should come with same quality tires as you buy at tire stores. And I will tell everyone about poor quality of Hankook brand.

FUEL/PROPULSION SYSTEM
Very strong gas smells coming from under the hood. After driving a few miles, fumes enter the passenger compartment. Had to stop parking it in our garage for fear of a fire before I could get it into the dealer. I've been told it's a fuel leak associated with the fuel rail system. I'm 20 days past my warranty and only at 29,000 miles. It's a nearly $2000 fix. GM was aware of the problem in 2021 as there is a service bulletin for this item. I should have been notified in 2021 that there was a possible problem which could lead to a fire or explosion.

SERVICE BRAKES, ELECTRICAL SYSTEM, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
The car will all of a sudden make a loud popping noise through the radio. It is enough to scare someone while they are driving and have a wreck. The brakes are very touchy to the point of almost giving you whiplash

UNKNOWN OR OTHER
When putting the vehicle in park I receive a messege saying "shift to park" this means the vehicle is not recognizing I put the vehicle in park. This is a safety issue my truck is not even off when this message pops up. GMc knows about this issue and their is not a recall on it. Dealer will not fix the issue becazue it actually has to say that messege when they are diagnosing the problem. It does it randomly but more frequent now. I call gmc the only thing they can tell me is record it when it does it as a paper trail I guess. They are saying the same thing the dealership is saying they can't diagnose the problem without the shift to park messege. Been having this problem when I hit 20,000 miles

VISIBILITY/WIPER
Front wipers spray only on one side, the working side changes, sometimes it only squirts on one side, sometimes it sprays over top the roof of the car, sometimes it doesn't work at all. Reservoir is full, rear window spray nozzles always work properly. I'm unable to wash away debris, in winter with snowy roads it can leave salty/muddy windows. Sap from the trees & pollen create poor visibility. No warning lights are on, never have been. This happened without incident.
