2015 Chevrolet Silverado Complaint Log

For several years this truck will at times start "grade braking" on its own. In other words, at speed, ie: 55 mph, the computer chip will tell the transmission to downshift to assist in "grade braking". The danger is that it actually speeds up the truck, and while attempting to stop at a stop sign, (or light), the truck is actually speeding up, while I am actively pushing on the brake pedal to stop at the light. I ended up having to replace the transmission with a new (rebuilt) transmission. I hoped this would end the problem, but now once again, I have the problem occurring with the replacement transmission. GM tells me they cannot program out the grade braking component. This is a very dangerous situation in which one day I will be unable to stop where required, due to stopped traffic, or a stop signal.

The truck started making a loud ticking noise.The truck then started stalling when pulling out into the road from a standstill.Then the check engine light came on.Took it to the dealership. Was told it is the common lifter problem.That GM has known about for years. But refuse to address. Please let GM know about this problem.Thanks.

My wife came home and told me there was something wrong with our truck. I went and inspected it and found nothing. The next day i drove the truck about 30 miles up river. Coming home I was traveling around 55 mph the truck came to a sudden slow down as if I had locked up the brakes then drove fine again. This happened three or four times not as bad as first time. While in town stopped at a light it tried to take of. Not like something giving it gas but like it was in gear and the brake wasnt going to hold it. Almost put me into a school bus ahead of me. Then the rest of the way home it kept binding down and releasing then binding back down. Hard to control but not necessarily a break problem. Its something else. I have worked on vehicles all my life, professionally for 25 years. I never seen a vehicle do this. It has to be in the transmission. Maybe something in the torque converter would be my guess. I have heard of the issues with the 8 speed ever sense this happened I have parked this truck. I cant afford a need transmission that doesnt actually fix the problem from what i hear. I feel GM needs to do something here. At least pay for the parts to fix it

As reported in a previous recall, the electric steering cut out on me on two separate occasions during low speed turning into parking spots.

Inability to brake at low speeds. Brake vacuum pump failing at 100K miles. I can submit photos and report later.

The service Trailer Brake System has a defective wiring harness.

Trailer brake assist warning keeps going off at different times with no trailer attached. Quite annoying and unsafe distraction.

Driving 25mph for 3 miles leaving my house speed limit increased to 55 and as i stepped on gas to speed up truck shuttered, shook, and ck engine light came on. #6 cylinder has no compression, found info about common chevy problem 122000 miles.

Anytime I pull into the parking lot and I have to pump my brakes more than once the brake pedal stiffens up and the truck does not stop it has almost caused a collision and almost went through the window of a business it is to the point where every single time I drive it does this from what I heard it is the vacuum pump it does not provide enough vacuum for the brake booster so the brakes do not work it cost about $250 for the OEM part and that is not guaranteed to work the problem will persist later on down the road after more mileage put on the truck

The service trailer brake system warning keeps appearing while driving without a trailer and with a trailer attached to the truck. There is a defective wire harness located on the left side of the steering wheel that needs replaced to fix the issue. The warning alert appears and dings while driving causing distractions while driving down the road.

vehicle is shifting hard between 1st and 2nd. it only seems to do it at lower speeds. the RPMS had a shudder between and only once the truck has been running for awhile. has been in to an independent service dept. at the local dealer where it was purchased and has had all work done since purchased. there are no warring lights or check engine messages. they flushed all fluids and hooked to diagnostic machine found nothing. had it back for a week and it did it again. Took it back to them and had them ride along so they could see what it was doing. they replaced the torque converter although the shudder is gone but it still shifts hard between 1/2

Randomly the brakes get stiff, even while on a hill or stop and go traffic. I noticed the first time after first buying it that while on an exit driveway at a decline, the brakes felt like they slipped or went away. I had to push them hard all the way down and thought I was going to roll into oncoming traffic. The truck soon after was making a noise and felt like it was losing power and revving after the keg was taken out and loss of gas mileage. The dealership confirmed the brakes vacuum pump and the high pressure fuel pump were both bad and the gas was leaking into the oil causing problems and possibly ruining the engine, they stated both would need to be replaced. Check engine light comes on soon after fresh oil changes everytime and codes were shown on computer for running rich. No codes after the initial oil changes due to the warning lights appearing after a good amount of gas has leaked into the oil.

The electrical system randomly shuts down. It has done this multiple times in the past several months. Everything shuts off, including engine, power steering, etc. It has done this both while sitting idle and when driving. Most times, it will come back on after a few seconds but I have had to coast off the roadway, and have it towed back home. This is VERY DANGEROUS!!! Fortunately, the times it has shut down while driving has been during daylight hours because if this were to happen at night, I would lose all lights, therefore making a serious crash almost certain.

Trailer brake system alarm keeps going off.

Trailer brake system I have owned this Chevy Silverado 2015 since 2018 when I purchased it certified from a used car dealership in upstate New York. About one year into owning the vehicle I started to experience an alarm that was flash trailer brake system. This alarm would beep and flash in my center consul restricting me from sight distracting me from driving and is almost impossible to drive the car without distraction. I checked YouTube I called the manufacture I did so much to figure out what was going on and why this was happening considering I do not show any thing I did not understand why the trailer brake would cause such a problem considering I never told anything.After about three months of driving the car this trailer brake system alarm stopped. Now recently 2022 the trailer break system alarm is back and flashes nonstop and is relentless. I cannot listen to music I cannot hear my own self think the alarm is so loud and so distracting I would rather walk to the store then drive the truck I am forced to drive this truck because of the fact that I need to get to work but the safety hazards that are now limiting me and I am afraid this is going to cause a major accident or loss of life. I recently discovered that this is a manufacturers wire harness malfunction due to faulty wiring and a low-grade wire harness system. Before this gets any worse I need some sort of help. Knowing that it is impossible to fix without thousands of dollars being spent and finding a specific electrical auto technician to fix it it is nearly impossible to have this fixed Chevy refuses to even acknowledge there is a problem I need someone to please help me and the other Chevy Silverado owners to get this under recall so that these wire harnesses can be replaced please help us my name is [XXX] my address [XXX] [XXX] is my cell phone number INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

BRAKING SYSTEM HAS BEEN A PROBLEM FOR A LONG TIME. THE VEHICLE WAS TAKEN TO A LOCAL REPAIR SHOP. THERE THE MECHANICS REPLACED THE FRONT BRAKE PADS AND REAR BRAKE PADS. WE CONTINUED TO HAVE PROBLEMS WITH THE VEHICLE. WE WERE NOT AWARE OF THE RECOMMENDATIONS TILL RECENTLY SO WE TOOK THE VEHICLE IN TO DEALER. MILEAGE WAS 169201. THE BRAKES WERE FIRST INSPECTED 6-29-22. THE MILEAGE AT THAT TIME WAS WELL BELOW YOUR CUTOFF OF 150,000 MILES OR 10 YEARS. THE DEALERS HANDLING OF THIS DOES SEEM UNREASONABLE. THIS IS MY HUSBANDS VEHICLE I REALLY DONT KNOW EXACTLY WHAT HAPPENED AND WHAT DATES. WHILE BACKING UP HIS TRAILER HAS BEEN A PROBLEM SEVERAL DENTS ON THE SIDE OF IT SHOWS BRAKING PROBLEMS. I THINK 1900.00 IS EXTREME TO REPAIR WHAT YOUR COMPANY IS WELL AWARE OF IS A PROBLEM. YOUR CUSTOMERS SHOULD HAVE BEEN NOTIFIED THIS WAS POSSIBLE RATHER THAN LEAVING THEM TO FIGURE OUT WHERE TO HAVE IT CHECKED. I HOPE THIS WILL CONVINCE YOUR COMPANY TO DO WHAT IS RIGHT. THAT WILL DETERMINE WHAT VEHICLE WE WILL PURCHASE NEXT.

2015 Chevy Silverado, 62,300 miles. While driving at highway speeds. The air condition compessor locked up. Causing the engine to die and causing the loss of power steering and power brakes. I was unable to brake in a timely manner and had to swerve to avoid stopped traffic. It seems there are thousands complaining of the same issue online. There was no warning. I have contacted the dealer and they say there is no recall.

transmission failed at 70 500 miles

This is a 2015 Chevy Silverado, I continuously get a message reading "Service: Trailer Brake System". This error message would continuously chime every 5 seconds, no matter if I cleared the message with the check button on the steering wheel or left it on. This chime would override the radio, phone calls, turn signal chime and any other noises put out by the vehicle in addition to covering the digital speedometer readout. I have yet to take it to a dealership as today was the first repetitive issue lasting over 30 minutes. I first noticed this at random over the last 2 months, but these messages would stop after 2-5 minutes worth of chimes. I plan to take this to a dealer for inspection, but wanted to check for recalls/ report the issue before doing so.

Trailer brakes went out while towing a car

I have been waiting for nearly a year to have this recall fixed by GM! All my dealer's service people do is shrug their shoulders and tell me I'll get a letter when they have the parts. How much longer do I need to wait?

I am having issues with my transmission. When I first turn on the truck in the morning, put it in gear, and lightly accelerate the truck accelerates way too fast then cuts out the power. It is enough to throw me forward or back in my seat and it honestly is frightening. I am also having problems with the vehicle shifting incorrectly causing me to have no power or a sudden surge of power. This is usually when i have slowed down and them am trying to accelerate again. Also, When I am slowing down to stoplights, the vehicle will occasionally shift down to too low of a gear and act like i am slamming on the brakes. I have had several close calls with this truck due to this issue. Gm knows about the issue and has refused to recall the vehicles that are having these problems. They are recommending changing out the fluid multiple times at the owners costs. This has resulted in several class action lawsuits. They also have gone to the lengths of changing warranty coverage to no longer include abnormal shifting. This is not safe. This is causing accidents and they are actively covering it up. Please help the hundreds of thousands of people that are having issues. We need your help, I need your help and gm is no longer standing behind their vehicles.

The contact owns a 2015 Chevrolet Silverado 1500. The contact stated that the vehicle was taken to the dealer for an air bag recall, the contact was asked to move the vehicle forward and stop at a certain spot; however, the vehicle failed to stop immediately when the brake pedal was pressed.

The dealer informed the contact that the failure was related to NHTSA Campaign Number: 19V645000 (Service Brakes, Hydraulic); however, the VIN was not included in the recall. The contact was informed that the brake booster had failed and needed to be replaced. The vehicle was not diagnosed or repaired. The failure persisted and had occurred several times. The failure was most persistent when on an incline, in reverse, and during colder weather. The manufacturer was not made aware of the failure. The failure mileage was approximately 70,000.

Service trailer brake system alert is going off constantly during driving the vehicle. I was not towing anything and have only ever towed something one time with this truck. The alert produces a chime and flashes the alert over the speedometer screen.

While driving, engine running - the whole electrical system including the engine just stop - totally dead including lack of power steering. Several times it was a fraction of a second, and then all systems came back on and engine resumed running. Another time, I had to coast off the road and try to steer without PS. After waiting a bit, the engine restarted. Even though you only ask for 1 date, this has happened several times. Most recent was yesterday, 5/2/2022. Before that it was March 13, 2022. Before that, I believe it was several years ago.

steering and braking stops working during low speed. AC stops working and several components flash a warning message Trailer hitch and stabilizer and engine light appears sporadically. It shows that I do not have recalls but I believe the repairs in the past were not done correctly. old software or a electrical short from an faulty part!!!!!

Currently, the AC is no functioning properly. Mechanic states that the hose leading to the compressor that's mounted towards the radiator is cracked and he can see oil from the AC system that has leaked out over time. Parts are being ordered to replace and repair so that the AC system will work properly. Improper AC function is not acceptable during the spring/summer months, and AC is needed to be able to cool the vehicle down There were no warning lamps or messages. We determined the system was low on coolant because it was not cooling properly.

The truck just shut down for no reason,then can not turn it or can not use the brakes to stop it,then will not start,then it will start in time.

The vehicle is experiencing a low speed brake failure where the brakes either pulse like ABS brakes or there is no brake at all and you have to push hard to the floor to get brakes. I have seen some reviews that say this was a recall but I did not find anything on your site and I have not received a notice.

Transmission slipping, set cruise control and it would engage for some time and then disengage without warning. I followed all maintenance requirements for the transmission like flushing the transmission at the appropriate mileage.

The contact owns a 2015 Chevrolet Silverado 1500. The contact stated that while starting the vehicle, the contact heard an abnormal sound coming from the vehicle. The vehicle was taken to an independent mechanic and the mechanic stated that the catalytic converter needed to be replaced. The vehicle was not repaired. The dealer was not contacted. The manufacturer was not contacted. The failure mileage was 91,000.

Slow speed braking is severely affected upon engagement, such as backing out of my driveway, or maneuvering into a parking spot. The brake pedal will pulse as if the ABS system is activating, however, upon reaching/ keeping idle speed, the brake pedal will become very rigid and the pedal is very hard to compress downward. Once the vehicle is stopped, and power is applied again with the gas pedal, normal braking is restored.

At low speed I get a hard brake pedal like low vacuum ( booster pump failure) maybe.

Service Trailer Brake light comes on continuously making it very distractive when driving no matter if you dismiss the message on the dash.

On an interstate offramp facing downhill moving at a slower speed 15mph or slower, application of brakes resulted in a brake pedal that could only be depressed about an inch (outside of normal function). Braking distance and response was drastically reduced. Decreased braking performance was experienced shortly after while reversing into a parking spot at low speed (1 mph), almost hitting a concrete wall in an underground parking garage. Vehicle is being inspected by a Chevrolet dealer Service department
