1 Equipment problem

Failure Date: 03/23/2026

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.

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.
