Rear window defroster overheated/caught on fire. It will be available for inspection unless GM rectifies the issue and removes the components in question. Cabin filled with smoke and a small fire broke out immediately behind the rear headrest/seatbelt location. Rear window section shattered, most of the glass is intact but some pieces were ejected. The problem has been reported to GM but is still in the investigation phase. The vehicle has not yet been inspected as I have just started the report filing with GM. No warnings, indicator lights, etc. were present before, during, or after the incident.

This truck is on its 3rd transmission. Both failed the exact same way. The torque converter overheated due to the v8 to v4 mode and warped the transmission. The first transmission swap was under warranty. The second swap was not. Which I had to pay 4800.00 to replace. My mechanic told me this is a known issue with this model and they had to upgrade the transmissions. The second transmission that went in did not lat but 50k miles. Ridiculous. I do not drive my truck aggressively, nor is there any reason the trans should have failed twice with the exact scenario. It had increased rpms on the engine but truck did not move. When speed would slow down it felt like I was driving on rumble strips and I was on a back country road. I should be compensated for the second trans swap. Gm knew about this issue but never put a recall out. I am not a satisfied customer.

My 2014 silverado high country has a 8 cylinder 6.2 engine. After coming to a stop often there is steam coming from under the hood. The temperature gauge runs high and there is the smell of coolant leaking. I was told by the chevy dealer this is caused by under spray? It happens on dry days, rainy days and laving a car wash bay. I've been advised it is a hairline crack in the radiator and gm knows they've had problems.

A/c only blows hot air, cannot defog windows at certain times and increases the likely hood of my newborn getting over heated. It is a known issue with general motors and they said it is the federal safety agency that will not do the recall because it is not dangerous. Well we will see how dangerous it is when we cant see because it will not defog window or what the hospital bill will be when my newborn overheats because of a faulty A/C compressor and bracket for the hose. A 2014 should not need a $1600.00 repair. That is 3 months payments for a A/C.

2014 chevy silverado lt with 27,000 miles. Noticed coolant smell near front of truck after driving it. I looked on line and found several sources complaining about the same issue with coolant leak. I took my truck into the dealership to check coolant leak. They found out the radiator was cracked and told me gm has an issue with the thermostat overcycling causing the radiator to develop stress cracks and leak coolant. My truck however was pass the 36 month bumper to bumper warranty and my truck doesn't fall under their special coverage bulletin 15829 to fix this issue for 5 years or 100,000 miles. Quoted around $900 to $1,000 to replace thermostat with a new version that will not stress crack the radiator and new radiator (same part as original) is put in the truck. So if gm knows they have a problem but will only fix certain vehicles that have the same faulty thermostat. How is this right?
