2025 Chevrolet Tahoe

An Over-The-Air / Chevrolet Dealership software update removed a physical, hands-on-wheel control function, forcing me to divert my eyes from the road to the central touchscreen to perform a basic driving task (channel surfing) on the radio. Specifically, the right front steering wheel toggle used to allow you to scroll sequentially up or down from one radio station / frequency / SiriusXM channel to the next. The new functionality only allows you to select preset stations, duplicating the functionality on the left rear (back side of the wheel) steering wheel toggle button. The only way you can now scroll sequentially up/down from one channel to the next is by taking your eyes off the road, reaching over to the center console, and swiping left or right to move from one channel to the next. This is far more dangerous as it is a distraction to the driver and it takes the driver's eyes off their forward view.

ON JUNE 2ND 2026, the air conditioning in my 2025 Chevrolet Tahoe failed without warning. The system began blowing warm air instead of cold air, making the vehicle uncomfortable to drive. At the same time, I noticed that both front ventilated (cooled) seats had also stopped working. Although the seat cooling indicator lights illuminated when activated, the seats did not produce any cooling. I called to schedule an appt and took the vehicle to the dealership for diagnosis and repair on june 4, 2026. The dealership determined that the A/C condenser had failed and replaced it. I was advised that the repair had been completed, and I picked up the vehicle believing the issue had been resolved. Shortly after the repair, it became apparent that the problems had not been fully corrected. While the air conditioning initially appeared to function, the ventilated seats continued to provide no cooling despite appearing to operate normally. This marked the beginning of an ongoing series of HVAC-related failures that ultimately required multiple return visits to the dealership.

The air conditioning/climate control system failed. I initially brought the vehicle to the dealership on June 4, 2026, because it was blowing hot air. The dealership replaced the condenser on June 5, 2026. On June 12, 2026, the driver's side again began blowing hot air while the passenger side remained cold. By June 13, 2026, both sides were blowing hot air. The vehicle is being returned to the dealership on June 15, 2026, for an additional repair attempt related to the recurring air conditioning failure. The excessive heat created a safety concern because the cabin temperature exceeded 100°F despite the air conditioning being turned on. I developed hives and a rash on my face, neck, trunk, and arms from the heat exposure. Excessive cabin temperatures can impair driver concentration and increase the risk of heat-related illness. Yes. An authorized Chevrolet dealership diagnosed the issue and replaced the condenser on June 5, 2026. The problem reoccurred within approximately one week of that repair. The vehicle has been inspected by an authorized Chevrolet dealership and remains available for inspection by the manufacturer or its representatives. There were no warning lights or messages. The only symptom was the air conditioning blowing hot air instead of cold air.

On March 21, 2026, I rented a Chevrolet Tahoe (approx. 24,450 mileage driven). While operating the vehicle on a freeway at approximately 40–50 mph, the braking system and ABS failed suddenly without any warning. Barely no brakes were able to apply to stop the vehicle. It also started to show that ECS service (Electronic Stability Control) and Service Brake Pad Monitor. Many faults started to show.

While I was driving, my vehicle suddenly lost all power I encountered a misfire with the engine light flashing, and diagnostic codes P0353 and P0300 indicated a misfire on cylinder three. The coil pack and spark plugs for that cylinder were replaced, yet issues persist and problems continue. There is a strange popping and cracking noise coming from my dash. My brakes are also making it loud sound randomly when pressing on breaks yet brake pads are fine

My 2025 Chevrolet Tahoe Z71 3.0L LZO Duramax with approx. 3,380 miles experienced a sudden and complete engine failure while towing my camper on the interstate at night, in the rain, while traveling alone 375 miles from home. The vehicle lost power, displayed warnings, and became inoperable, forcing me onto the shoulder in unsafe conditions. The engine has been diagnosed as requiring full replacement due to a defective crank end play / thrust bearing, under Technical Service Bulletin (TSB) 25-NA-307. This is a significant safety concern for a new vehicle and could have caused a crash. GM has multiple documented issues with this model year, and the car has also experienced unresolved infotainment defects, as outlined in TSB #PIT6393F. Requesting NHTSA to investigate a potential safety defect.

After my vehicle experienced a brake system failure 3 weeks ago and I got my vehicle back from the dealership. I noticed that my vehicle has no emergency brake so in the event of this failure and/or future brake system failures there was no way to stop my vehicle. Their emergency brake is technically a parking brake that can only be applied when the vehicle is completely stopped. I'm not sure how a vehicle this unsafe would be even legally sold or allowed to operate on the roads.
