2014 CHEVROLET SILVERADO 1500 Engine Problems

When driving in traffic about 10 mph engine shuts down and power steering goes out. . When I slow to turn, the engine shuts down sometimes and the power steering goes out. No warnings. I’m afraid to drive it. I almost hit a lady while turning in a parking lot because the steering went out and it died. Sometime it’s hard to turn the key to start the truck. This has happened 9 or 10 times now.

I bought a truck from Paul Gerber Auto sales, Inc(used car dealer) in Omaha Nebraska. The transmission is bad because of the torque converter and a known issue where the transmission fluid gets too hot causing the torque converter to become damaged. There are also multiple known safety recalls with this vehicle and the issue with the transmission has been confirmed by a independent mechanic. The dealer had me driving it down roads that didn't take the vehicle through all of its gears so the problem wasn't noticed until after I had gotten on to the freeway. Went on the freeway I noticed that it was shifting up hard and downshifting hard as well as a rumble strip effects in the vehicle struggled to get up to speed or was sluggish. When I was clear and tried to pull out into a lane from an intersection the vehicle struggled to...

The air conditioner condenser has a small leak causing the refrigerant to leak out. This is a known problem with all gm Silverado 2014-2017 and a recall needs to be issued. They are all leaking in the same place due to a faulty weld from the factory.

Vehicle is experiencing intermittent electrical issues, including vehicle completely shutting off while driving, driver window security warning message appears, radio, outside temp and fuel economy will reset when starting the truck. Last time it shut down while coming to a stop, a message appeared on the driver information screen saying “3 key programmed to vehicle”. Sometimes before it shuts down while driving, the radio and dash lights go out followed by engine stalling and there are different messages that appear briefly, like, service stabilitrac, roll driver window down & 3 keys programmed. The truck has shut down on me while operating 7 times in the last 3 months! This is EXTREMELY dangerous as i lose power steering & brakes! It has happened while in the middle of a busy intersection, in a round about, pulling into a parking spot, driveway and while driving straight on a road. I have cleaned...

I am writing to report a significant mechanical failure with my 2014 Chevrolet Silverado, which I believe warrants further attention due to its potential safety implications and its connection to a widely documented defect affecting many GM vehicles equipped with Active Fuel Management (AFM) systems. The engine suffered lifter and camshaft failure. This is a well-known problem with GM trucks using AFM systems and can pose a safety hazard, particularly if the vehicle stalls while driving. Failed Component: The engine’s valve lifters and camshaft failed. The components and repair documentation are available for inspection upon request. Safety Risk: This failure caused loss of power while driving, creating a risk of stalling in traffic, which could endanger both myself and other drivers on the road. Confirmed Diagnosis: The issue was confirmed by the dealership where I service my truck, Team Chevrolet in Las Vegas, NV. They identified the lifter and camshaft...

twice know i have had the truck shutdown when turning to the left at slow speed . Took the truck to a maint shop and they had three codes in the computer but nothing they could fix so they cleared the codes and said to drive it and if it happens again to bring it in and they'll see what they can find out ,but my have to go to agm service center to have it checked . so I'm drive carefully and hope not to have a accident.

the truck went in for the fuel injector number 6 again. went in on June 13 and on the 12 as well. on the 12 they said it was the number 6 coil. they then gave it back but the next day had to be returned again for the same problem. this time they found the number 6 fuel injector was possibly shorted out. the service manager did call and said that i was right that it was the fuel injector. i feel that i paid for a coil that should not have been replaced in the first place.

I was driving home from work on 5/9/2025 and my truck slowly started to loose power and I almost got rear ended going up a hill. NO check engine lights or symptoms noted prior I was able to make it to the Chevy Dealer here in town where i Live and dropped off. dealer noted cyl 4 has a misfireand there is a tick noise on that bank.checked and found no compression on cyl 4, removed valve cover and found that the lifter for cyl 4 is broken and pushrod bent. After reasearching found this to be a common problem, contacted Chevy reagarding this as truck is low miles (88k) NO help offered.

While driving to work a month ago (3/19/25) I lost the power to accelerate out of nowhere. And my truck started making this noise, what I can only describe as a winding up noise while trying to accelerate. I was going 55mph on a busy morning commute. There were no warning lights. I pulled over and shut the truck off. Checked oil (even though it was changed a week or 2 prior). Oil was fine. Let truck sit for 10 mins then tried to turn back on, it started but had that winding up noise when just sitting in idle, the check engine light then came on after it was on for a minute or so. Ran codes at home, and truck started making an additional rattle noise on top of the winding up noise when had to be turned on. One code was the crankshaft position sensor, we changed...

EVERYTHING, it started with spark plugs and boots which is normal, then all of a sudden one ignition coil after the other, then the transmission, now it's the valve cover gaskets, the ENGINE oil cooler lines, the rear main seal, the oil pan itself, like literally everything. The places I took it advised probably getting a whole new engine. Mind you I just financed this truck 2 years ago. The transmission cost me $6,700 dollars out of pocket because my power train warranty wouldn't cover it because some wire. I don't know but there is seriously big problems with this year make and model. Also, the catalytic converters are bad and the exhaust manifold. All these things can't be wrong all at the same time unless there was a major issue prior to me financing when Chevrolet spit these trucks out.

Ignition lock actuator faulty. Causing ingition to be stuck in start position.

I have experienced engine failure in my 2014 Silverado 6.2L on 3 separate occasions. All caused by the AFM system. Rockers lock into the wrong position while transforming from 4 cylinder to 8 cylinder operation. The first two occurrences bent lifters and caused a failure to the catalytic converter. A certified GM service department at a local dealership replaced parts covered by warranty. On the third occasion the rockers locked into the wrong position, bent push rods, damaged the cam shaft and caused a failure in the catalytic converter. It was taken to the same GM service department at Lou Fusz Chevrolet. My 5 year warranty had expired and GM refused to cover the parts they had previously replaced a year prior. I was quoted approximately $10k for repairs and $16k for full engine replacement. After some back and forth with the service department manager I requested to speak with...

Vehicle has intermitten reduced engine display while traveling down the high way. Causes the vehicle to downshift and significantly increase engine RPM. I’m fearing if this continues to happen it will blow up my engine. The ecu shows code p2138. After some research I’ve learned GM is aware of this fsult in their vehicles and I believe they should be the one paying for their mistake. Not me.

When something is hit (or pot hole/ rough road etc.)stabiltrak warning and check engine lights flickers, all panel lights go out, and vehicle seems to shut down briefly because you can notice AC go warmer. This is a safety issue.

I have been getting the Reduced Engine Power message due to the drive by wire components and the truck will go into Limp mode. This is a VERY DANGEROUS event due to the fact that a driver not knowing when this will happen. I have pulled into the road many times before and have this happen, and when it does go into limp mode, you are dead in the middle of the road trying to avoid being hit by on-coming cars. It is a KNOWN issue with GM for years now and many Technical Bulletins have been sent out about it.

Lifter failure happened while traveling home from Florida to SC. I was towing a vehicle and barely made it home. Having to drive at low speeds on the interstate put me at risk for accident. Now that I’m home I’m losing money because I have been unable to work due to not being able to drive the truck. The dealership quoted me $4700 to fix when there is a known class action lawsuit for this exact problem. GM should just replace these motors. This is very dangerous. There were no prior warning signs it just started ticking after stopping for fuel.

The contact owns a 2014 Chevrolet Silverado 1500. The contact stated that while driving at slow speeds and making a left turn, the steering wheel and brakes became inoperable.

Heavy smell of gasoline in the cab and the bed of my truck as well as outside of the truck began on February 23, 2023. The truck is also harder to turn over or start since the smell has begun. Due to the gasoline smell, it is causing a nauseous feeling, severe headaches, coughing and a red flush over my wife’s face when she is in the truck. The transmission line leak has been leaking for quite some time and I have to replace the transmission fluid a least a quart of fluid every two weeks. I was not notified of the Safety Recalls for the Fuel pump pressure regulator and the Transmission oil cooler line leak/ fire danger on my 2014 Chevrolet Silverado 1500. I have taken my truck to be assessed by the Chevrolet Dealer on 03/13/2023, and they determined that my truck does indeed have both of...

Automatic fuel management system failure has caused a p0300 code as multiple misfire diagnosed to cylinder 4 dead with no compression. This vehicle is no longer drivable and I still owe $21,000. GM knows of this failure for a long time. At current I have no way to pay for repairs and making payments on a truck I can not drive. I bought this vehicle used at 83,000 miles and have put 16,000 miles on it in 2 1/2 years

Using a signal for lane changes causes cruise control to disengage, suspension messages and air bag failure messages as well as tire failure icon would all come on and when leaving the exit ramp and decelerating the engine would die and system would lock up without ability to steer. So dangerous. Then next trip all is good but the engine failing while driving has happened a half dozen times. The last incident was another engine failure during an exit from the interstate in November.

Steering assistance failed during slow speed turn into side street. Vehicle stalled with no power to steer or brake. Engine turned off allowing vehicle to dead stick accross two lanes of traffic for opposite direction. Vehicle came to rest in parking lot nearby. Had there been vehicles in those lanes an accident would have occurred. Dash board monitor gives signals that "stability track" off and check engine have issues. In August of 2017 received recall letter from GM citing problem with EPS (electric power steering). Took vehicle to Serpentini Chevy on August 13th 2017 and they reprogramed EPS Module. Milage at this time was 20,085. They did not charge for repair. In 2017 my vehicle had no symptoms of recall. Now in 2022 this EPS problem is happening with milage 54,000 twice almost causing MVA.

The contact owns a 2014 Chevrolet Silverado 1500. The contact stated that while driving at slow speeds and turning the steering wheel, the vehicle lost motive power. The contact stated that the vehicle also lost power steering functionality and then stalled. The contact referenced NHTSA Campaign Number: 17V414000 (Steering) however, the VIN was not included. The manufacturer was contacted and notified of the failure; and referred the contact to the NHTSA for assistance. The vehicle was not repaired. The approximate failure mileage was 65,000.

I have a 2014 Chevrolet Silverado 4x4 which the "O2 Sensors" are going out and causes my truck to run rich and lose horsepower. My truck does burn more fumes from the exhaust causing bad pollution in the air. Can type of action this be considered as a recall.

Truck has rough breaking at low speeds. It’s due to the break pump recall on this make, year and model. The break pump also makes a clicking sound when engine is running. Common in these trucks.

My vehicle started displaying a stabilitrak warning, gauge lights dimming, hard steering, and the ac turning off when I would push the brake pedal while driving. 15 miles later, while making a left hand turn, my vehicle shut off completely which caused a loss of power steering. I was able to avoid an accident as the vehicle did restart. Prior to this incident, I have taken the vehicle in twice to Chevrolet dealerships to diagnose this issue. Both times they stated they could not duplicate the issue so nothing was done. This seems to be a common issue for many 2014 Chevrolet Silverado owners.

The vehicle has experienced dash and screen flickering while driving. When stopped and making turns the engine shuts off and the steering is locked. The whole dash goes blank. The engine is not able to restart or click. Anit-theft warning comes on for no reason. I feel there is a safety issue when driving this vehicle but no recalls have been placed. I don't feel safe driving my babies in the car.

Make a left turn and lose all power the truck just dies in may or may not start right back up

Vehicle losses electric power steering specially at low speeds tends to jump to the right side or locks the steering wheel possibly accident if it continues. There are recalls on most trucks like mine but it seems that my truck is not in the list and it should be this is a real safety issue I believe that I report it to you before.

The contact owns a 2014 Chevrolet Silverado 1500. The contact stated while driving 15 mph, the vehicle stalled. The vehicle was restarted however, the failure recurred. The contact stated that there was no warning light illuminated. The vehicle was not taken to a local dealer nor independent mechanic to be diagnosed. The vehicle was not repaired. The manufacturer had not been informed of the failure. The failure mileage was approximately 48,500.

Transmission Light comes on to say cut engine off, if not done quickly, just dies. It can cut off at any time. I just purchased truck and took it to the chevrolet dealer they told me this year make and model has had a lot of transmission issues that the torque converter fails inside the transmission and they want 6000.00 to fix it, I have not had the truck 60 days

The vehicle will intermittently start to have electrical glitches such as loss of electric power steering, A/C and radio shutting off, stabilitrack shutting off and engine shutoff. I've heard there is a known ground issue with this model and its can be dangerous when moving if you lose steering control and engine control. This has happened multiple times the most recent was 6/28/2021

Towing 16ft stock trailer with 2 calves- Turning Left onto another 2 lane road which was downhill, Engine shut off during turn, power steering went out, had truck brakes pressed to floor, trailer brakes didn't react. Took everything I had to turn the steering wheel to keep from going off embankment on both sides of road. Finally got stopped when road flattened out. Thank goodness no oncoming vehicle!!! Message on dash to roll up drivers side window. Truck restarted! Truck only has 60100 miles. What is going on with this truck? I could have injured myself or someone else? Thank you in advance for allowing me to voice what happened today 6/28/21

problem first started about 6 weeks ago. slowing down making a turn my truck would shut down without any warning. once turning left in a four lane highway. once turning into Mc Donalds jumping curb and several other times. took into dealership for a recall told them about problem. they put analizer on it showing nothing. it has shut down several times since and a light on my truck finanally came on saying it was the trucks thief deterrent system. i will be taking this into my dealership again this morning but feel you should be aware of this problem as all control of truck was loss when turning into oncoming traffic.

My truck has developed a radiator leak after 39930 miles. I see from reading on the Internet this is a very common problem with this year of truck. Chevrolet even has a recall to replace the radiator but says my truck is not included. The recall notice is #15829. This ends up being a very expensive repair. I have been quoted $1428.00 by a Chevrolet dealer to replace radiator.

I CHOSE A USED 2014 CHEVY SILVERADO WITH 180K MILES. I MET MY SALESPERSON, BERNARD, ON SITE AT PUGMIRE FORD, IN CARROLLTON, GA. WHEN I TEST DROVE THE VEHICLE, THE TRUCK HAD OFF ROAD TIRES, SO I REQUESTED THAT PUGMIRE PUT REGULAR TIRES ON THE TRUCK BEFORE TAKING POSSESSION. THEY AGREED AND THE TRUCK WAS DELIVERED A FEW DAYS LATER. SOON AFTER DELIVERY, I NOTICED A SOFT NOISE SEEMINGLY COMING FROM THE ENGINE. I INFORMED MY SALESPERSON BERNARD OF THE ISSUE. HE ASKED ME TO BRING THE TRUCK BACK FOR REVIEW. I DID & BERNARD TOLD ME 'IT HAD SOMETHING TO DO WITH THE EXHAUST SO DON'T WORRY ABOUT IT. IT WILL GO AWAY AFTER A FEW DRIVECYCLES'. I DIDN'T BELIEVE HIM SO I HAD THE OBD CHECKED, THAT INDICATED THAT THE CATALYTIC CONVERTER HAD FAILED. I SENT THE DOCUMENT TO BERNARD, THEN I ASKED IF THE VEHICLE HAD A...
