2010 Chevrolet Silverado 1500: sudden loss of power

Filed Oct 16, 2024 · Engine, Transmission · GA

GM 3.0 diesel engine has a coolant control valve that fails putting the vehicle into a reduced power mode causing the vehicle to have significantly reduced acceleration and putting the engine fan at full to reduce engine heat. When stopped, the engine had been running very hot as you can hear the popping from the metal as it cools off. The part to repair this issue is 40009158 and is being replaced by 40009452. This part is on a nationwide backorder with hundreds on the waiting list just at this time for a repair and no clear picture of when parts will become available. Many other cases have been reported since 2021 for the same issue with the 3.0 GM Duramax engine with engine code/styles LM2 & LZO.

The component unknown, I do not know what caused this to happen. The charging system suddenly drops and power to the truck is shutting off or losing power. The electric doors and dash lights, plus trailer frailer all occur and locks going up and down. Today on a major highway in Kansas City, All dash lights and indicators came on and then the truck started to stop in major traffic. I had to put the transmission in neutral and out of gear and try to keep from losing control of the truck as the were trying to lock up. I quickly shut of the ignition and then turned it back on. I put on a new alternator thinking that would fix the problem. Well 200 dollars later and two days later is when this major problem cause me almost to be in a serious accident. I usually get my service done at Cable Dahmer Chevrolet in Independence MO. I am beside myself, as I know of another owner that has the same year and his is now doing the same thing. Is this a serious problem that may have been going on in other similar vehicles, I would say so. Since I did not panic and made the truck keep going and stop it from locking up, what would be the safety factor of someone, who could not know what to do? No warning lights or nothing lit up just cruising along. No accident and have not had it access yet. I have yet to contact the Chevy dealer and yes it was a high risk concern. No one was hurt or injured, but could have been. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving on a highway stabilitrack turns off then few seconds later traction control turns off then I get either a cylinder misfire or throttle body code. Truck then goes into reduced power mode with rough idle. I can clear the codes with obd reader and it runs fine for a while.

Service trailer brakes soon, warning comes across display & loss of trailer brakes without warning. I was driving on a bright sunny day, dry roads, traffic ahead of me came to a stop. I was pulling a 7,000 pound travel trailer stepped on brake all was fine 1 minute, service trailer brake soon warning display came across & no trailer brakes & almost caused an accident. As long as the display says service trailer brakes soon, you have no trailer brakes, there is no warning or back up system just hope for the best, just glad I wasn't going down a mountain. This time I went to have oil changed & service trailer brakes soon displayed & truck ran rough. Took it to the dealership, after 3 days at dealership, mechanic says the "fuel pump flow control module" has to be replaced, same as in recall # 14515b. This warning will also display without trailer connection & vehicle power loss happens until restarted. This is dangerous as there's no warning or certain situation or weather condition that makes this any different. This happens whether your city or highway driving, doesn't matter.

I own a 2010 chevrolet silverado 1500. While driving approximately 68 MPH on the highway, the check engine warning indicator illuminated, service stabiltrack and reduced engine power warning all came on at once causing the truck to reduce speed quickly and dangerously on the highway. I was almost rear ended as the my speed went from 68 MPH to less than 30 MPH in an instant. Thankfully the gentleman was able to slow in time- through on his hazards and help escort me to the emergency shoulder. My truck has approximately 67,000 mile on it and this problem has now happened 5 times at various speeds. I have researched this matter and this is know issue and is all over the gm forums with multiple models. Each fix reported comes after customers have spent hundreds of dollars for the dealers to locate the issues. Gm/chevy are aware of this issue and yet there is nothing about a recall for this issue even though it is caused from a known defective part and causes a dangerous driving situation!

My husband and I were driving about 45 MPH down a steep hill, towing a utility trailer, on sr87 in the mountains when the door locks clicked and the engine turned completely off with no warning. The steering wheel locked up and the brakes did not work. My husband put the car in neutral as it accelerated down a cliff and attempted to restart it with no luck. There were no cars immediately around us so we were able to coast to a stop on a steep incline. When we got out to check it, there was oil all over the wheel wells and still no warning lights had come on. We took it to the dealership and they told us the transmission was completely blown on our 6 year old truck. There was zero explanation as to why this would happen as well as to why we had no warning prior to the engine shutting off. We were told to pay better attention to the temp. Even though it did not overheat. Chevy offered no relief or help. We were quoted a price about $2000 less for the initial transmission repair than it would have cost so we took it to a non-dealership shop to repair. This weekend, the check engine light came on out of nowhere indicating loss of power and the stabilitrack warning came on even thought that was previously repaired by a dealership on a tsb about a year prior to the transmission going out. The code it threw this time was p0305 and we were on very limited power driving back home from a road trip. Could not go more than 40 MPH uphill. Extremely concerned for our safety since the vehicle can turn off with no warning. Also, the money spent is ridiculous.

5.3l engine oil consumption. Engine consumes 3 to 4 qts of oil between oil changes and fouls #7 spark plug causing extreme loss of power. Oil consumption is getting progressively worse. Dealer claims it is a known problem, but my VIN is not included in warranty extension.

Entire vehicle shut off as if the key were turned off , this has happened many times- I lose power steering, all electrical, steering etc. Very frustrating bc chevy states that there is no recall for 2010 model silverado so I'm expected to pay out of pocket??? This isn't right- I've always been pleased with my chevys but not with this one.

Driving 65 on cruise control when check engine, stability control lights came on. Message center said reduced power I got to a small service garage and he told me I should shut it off wait 15 minutes and it will reset and it did. I drove another 80 miles again the same thing happened. The first garage guy told me it was a gm issue and I should go see them they should repair it. He said it was a problem with the throttle body assembly and in the cold it get sluggish and gm should fix it because they had problems with some of them. It happened again 20 miles later. I got back to the gm dealer where I purchased it he confirmed it was they throttle body assembly but didn't have time to replace it. He offered to clean it (free of charge) and sent me on my way telling me if it happened again I should make an appointment to replace (approx. 400-600 dollars). I done some investigating on this matter and found this was a common issue. I stopped at another gm dealer and explained my problem he confirmed the original theory checked the VIN # and told me gm is fixing this problem for 10 years from the original purchase date. I guess I need to stop buying from my original gm dealer where I had purchased my last two vehicles. I have not had a problem with it again but I have only driven 600 miles since then.
