Thermostat cycling causing cracking in radiator. This is a factory problem that should absolutely be under warranty

- Northbrook, IL, USA

Truck has 98,500 miles on it. Radiator is cracked and leaking, roof leaks when raining, electric power steering randomly jerks the wheel out of your hand and almost causes you to crash.

- Wasilla , AK, USA

I estimate this has happened over 10 times. I lose all electrical power to the vehicle and the car shuts off, often this is preceded by loss of power steering and low speed. The last time this happened when pulling out into traffic; the steering kicked back, the truck lost all electrical power, dash went blank, radio dark, including loss of head lights, I will reiterate that this happened while pulling into traffic. This truck cost me over $40k new and I believe Chevy is aware of the problem, then simply don't want to cover the cost of parts and labor to fix. The dealership told me they had no idea what the issue could be, then I found several GM documents online. It appears this is a known issue, and they even list 2015 Silverado on documents. Bulletin No.: 18-NA-161 (The issues in this match exactly what I've experienced) also Reference Number:N172085440 Please help me convince Chevrolet to fix this issue or force them to do a recall.

for months i have been experiencing small issues at first, turn signal quit making noise, and then the radio quit working, this issue would only be corrected by turning off the vehicle, and restarting it, now the problem has gotten worse, tpms lights up on the dashboard the stabillitrack icon appears, and vehicle appears to stall momentarily and the radio goes blank, the most dangerous part is the electric steering wheel locks up, i have read several complaints online about this issue, and find no solution has ever been recorded, so far i have experiment this issue at low speeds and it is a interment problem that randomly happens

My Silverado has already had the software upgrade related to the previous vacuum pump/brake recall (N192268490). It initially helped, but now the brake pedal is again extremely hard to press at slow speeds, such as in traffic. You need to almost stand on it to stop. It appears that the deterioration is back where it was before the software "fix." I will be taking to the dealership this week and requesting a replacement of the vacuum pump under warranty or recall. I am beyond regular powertrain warranty at this point, but brakes seem like they should work past 80K.

Radiator is cracked. Same problem and same model radiator as is in the 2014 model of same vehicle. There is a recall for the same problem in a 2014 model but not 2015, like my vehicle.

- Appleton, WI, USA

My radiator is leaking with only 48000 miles on it. There has been a recall on the model years prior to and after mine, for the same problem. A radiator should not have cracks caused from a thermostat problem in this short amount of miles. It is a slow leak and I am going to have to replace the radiator before it causes other problems or gets worse.

With only 79,600 miles the engine began misfiring. We took it to 2 independent mechanics and were told the lifters needed to be replaced causing $5600 in repairs. We were followed all the recommended oil changes and maintenance. After investigating it we discovered this engine failure was known to GMC as it has effected several other GMC truck engines manufactured between 2011 and 2014.

Reporting that GM is aware of leaking in the radiator, transmission lines and oil coolant lines but no recall is listed. I am now having issues with all three and having to replace them.

- Bangor, ME, USA

I have about 85000 miles on my car, I was driving to work and the engine light came up. The code for the engine light came up as P06da which most likely indicates a problem with the engine oil control solenoid (based on most of the videos and reviews on the internet). Unfortunately, GM never made a recall about this!! this problem costs about 3K to fix at the dealer.

My truck had an afm collapsed lifter failure. It occurred under a hard acceleration event to change lanes. The dealer replaced the lifter, returning the vehicle to me. I got down the road, tested it under hard acceleration and it happened again! this time there was a lot of internal engine noise, really loud. I asked the dealer if they ntested it under a hard acceleration; they did not. They replaced the #6 piston and the valves associated with the #6 piston. All work performed was done on #6, even the initial collapsed lifter. I picked it up again and again a hard acceleration produced misfires! I had it towed it back to the dealer and asked them if they had tested it with hard acceleration. The response was @ 3300 RPM. I told the service writer that, if you do not test it under hard acceleration you will not even have it misfire! he redid the test and voila, he can see it now! technical resources told them to replace vlom, or "valve lifter oil manifold". I got it back and it does work, more or less. A hard acceleration will produce uneven acceleration but without the previous issues. I am working for now. I conducted some further research which I am probe to do and found an acdelco youtube video: Https://www.youtube.com/watch?V=mkly7xmmsos&feature=youtu.be&fbclid=iwar2zvzpvj6Z6E3seljzgvxzeru8ptllkgpkqtfxmrsns7oqencolhrrgi_I. This video states that if you have an afm levent that involves a collapsed lifter you must replace a plethora of parts. That was not done. I have changed my oil on a more frequent basis than GM requires and I use amsoil signature series10W20, the best you can buy! I also use their EA0 filters which state you can go up to 25K miles or 1 year between changes! I typically do 10K miles as a high point. I have swicthed preferred dealers to get a different technical response...help!

Air conditoner isnt working there is many complaits for cracked lines and faulty brackets

I was on a family trip with my wife and kids and the engine temperature raised and system said to idle engine until it cooled down. I was able to cool the engine down and get the truck home. The Chevrolet dealer diagnosed a coolant leak at the radiator. Service bulletin pi1513F refers to this as being caused by a faulty thermostat which results in fractures in the radiator. "this condition may be the result of excessive thermocycles within the cooling system caused by excessive cycling of the thermostat. These excessive thermocycles within the coolant system may cause the tubes to fatigue, crack and leak at the radiator headers. To correct this condition, a new thermostat has been designed that eliminates the thermostats excessive cycling." The quoted cost to replace the radiator and thermostat at the dealer is $1800 GM has apparently extended the warranty to 100000 miles under a special coverage adjustment on the 2014 models, but not the other affected model years.

Often, when making low speed turns the entire engine and electrical system shuts off. There is no power steering when this happens and it's difficult and dangerous to try to coast to a safe spot to try to restart the vehicle. Generally, it starts back up again within a few minutes. In the three years that we've owned the vehicle, it has been to two different Chevy dealerships more than once and both dealerships say there's no problem. It's frustrating that it seems to be a common issue yet there's no answer to the problem and no recall.
