general problems of the 2025 Chevrolet Blazer

I was going to park in a parking lot, when my car suddenly accelerated rapidly crashing into the building.

Windshield leaking water inside of drivers compartment, headliner & side pillars (causing stained areas) as well as the top of onstar and electrical buttons on the overhead console . Found wet cup holder. Vehicle does not have a sun roof. Gm is aware of this issue from the factory gm plant in ramos arizpe, mexico. This defect is because of lack of not being sealed properly during the assembly process. The windshield has a factory oem rubber seal attached to a new windshield. This rubber seal is not a part that can be purchased separately to fix the problem. By replacing the entire windshield with the new factory rubber seal and the channel that the entire windshield fits into is resealed with urethane should fix the issue. . Trying to reuse the current windshield & rubber seal and using sealer to reinstall it stretches out the rubber seal & will still leak. This leak can get into the electrical controls for safety system overhead controls. Extra care must be taken to remove the windshield as to not damage the roof line in anyway. Vehicle is going back into dealership to fix issue again. Vehicle was resealed with existing windshield and showing signs of leaking on l&r pillars.

2025 Chevrolet Blazer ev awd purchased 5/23/25 (under 3,100 miles) the vehicle's telematics control module (tcm) has failed, disabling the built-in navigation system, onstar services, remote start, and my Chevrolet app connectivity. The dealership confirmed the tcm needs replacement and the part is on backorder with no eta. This is a known issue affecting this model. I am reporting this as a safety defect for the following reasons: the 2025 Blazer ev does not support apple carplay or android auto. With the built-in navigation disabled, the only way to navigate is by using a phone, which requires visual attention to a separate small screen while driving. Under pennsylvania's hands-free law (75 PA. C. S. A. § 3316. 1), use of handheld devices while driving is a primary offense, making phone-based navigation both unsafe and legally problematic. On at least one occasion, the navigation system appeared to be functioning normally at the start of a trip but was providing materially inaccurate directions mid-route (e. G. , instructing me to turn onto a road I had already been traveling on for miles). A system that displays as operational while delivering incorrect routing data is dangerous because the driver has no way to assess its reliability before departing. Gm's ev concierge characterized the loss of navigation as a non-safety feature issue and suggested using a phone holder. This response is inadequate given the vehicle's lack of carplay integration, which makes the built-in navigation the only safe, integrated means of route guidance. This vehicle has also required three prior unrelated warranty repairs in 10 months: a recall for a faulty rear parking brake harness (9/25), a 12v battery failure requiring flatbed towing (11/25), and a faulty tire pressure monitor (12/25). The pattern of recurring failures across unrelated systems at minimal mileage indicates a systemic quality issue with this vehicle.

The onstar is out, cant make a call to them, cant remote start on app, navigation doesnt work.

There is a really bad rattling noise that comes from the dash. The dash at the windshield you can push down very easily. Whem driving on rough road the ratteling noise is very loud and distracting. During daylight driving you get a very bad glare from the dash board in the windsheild. I havent found a dash mat yet to fox the problem temporarily but some people have mentioned trying felt.

1). Engine stopped on interstate hiway with just 2024 miles. Towed to chevy dealer. New engine installed. Upon return of car emission system failure. 2) car delivered with defective windshield with major (crackle) throughout very distracting at sunrise/sunset. Replacement not much better.
