Bought this vehicle new from dealer in Sept 2015 with the dealer installed flatbed already on it, on their dealership lot. Fuel mileage was poor from the first, "engine light on" from the first; transmission dragging from the first day we bought it. Service advisors and the salesman said drive it and it will clear out. It got worse. The dealership finally sent it to the company who installed the flatbed for them, and they said there was an electrical short in the fuel pump which they replaced. The automatic transmission did not shift smoothly when we got it back, and the dealership said "it performs as designed". but, this is an automatic 6 speed Chevrolet transmission in a 2015 Chevrolet 3500 Silverado with a 6.0 gasoline engine. The transmission drags from 5th gear and then drags in 6th gear. I have to let off the gas pedal for the transmission to shift. If I let it drag out, it uses fuel and sounds like I am stuck in gear. We have taken it to 3 different Chevrolet dealerships, and they say something is wrong but we can't take it apart to fix it. The service manager said for me to drive it until the transmission "blows up because it is under warranty". I took it to a reliable transmission shop, but they won't touch it because it is under warranty, but they said that there is something wrong that it does not shift smoothly into all 6 gears. It only has 3600 miles. We have to drive it once a week to keep the battery charged. I don't pull or haul anything with it. This is happening both in city driving and highway driving.

Camshaft lifter failure (collapsed / stuck), #1 cylinder after engine was idle for ~5 minutes. Vehicle had 9701 miles at time of incident. This appears to be a relatively common issues with regards to the active fuel management systems on late model GM vehicles equipped with this technology. The service writer at the dealership noted that they have seen several vehicles in for service with the issue of a "collapsed" or "stuck" lifter requiring replacement. There is definitely a flaw in the design or the grade of materials being used as a lifter should not be failing at this rate with very little usage.

I have a 2015 Chevy Silverado 1500 4X4 with 5000 miles. While driving to work ( less then 2 miles) my service 4WD system warning came up. The truck is stuck in 4WD can not switch it out. Also while stuck in 4WD turning is very difficult. Called dealership they told me it was safe to drive it in. While on my way to the dealership still stuck in 4WD my check engine and traction control lights came on. The truck started to shack and shifting at random and the RPM were all over up and down. I got to the dealership and checked in they took it for a test drive while I waited. After waiting 4 hours they tell me the engine has issues they don't know what or why and that it will be a few days before they will know anything. So that waiting game begins.

Vehicle has stalled upon initial acceleration after a stop. 3 of 4 of the times it happened were after a right hand turn. 3 of the 4 stalls occurred when vehicle was cold (no correlation with right hand turn).

- Agawam, MA, USA

Fuel leaking from engine. With 9595 miles on the engine the truck leaks fuel from the engine like crazy. Vehicle is 6 months old. Can't get Chevy to pickup the rig because they say I need to call the fire department - the fire department tells me there is nothing they can do - been battling with Chevy all day on this. Its a safety hazard cabin smells like the inside of a gas tank - I don't feel save driving it anywhere.

While driving my 2015 Chevrolet Silverado 1500 ltz with a 5.3 liter motor the RPM of the engine act erratic, it will increase and decrease RPM at will, I would say that it surges about 75 to 150 RPM, it especially does this going uphill. It is unsafe to be driving a vehicle that acts in this manner because you can't control the way you want to drive, I took it back to the dealer and they are trying to convince me that this is normal, which I know it is not normal, GM needs to figure this out and correct the problem.

I purchased a brand new 2015 Chevy Silverado and in the first week I had it, while driving, the truck just simply completely shut off. Dealer claims they have never heard of this and after keeping truck for days stated could not find any issues. About one month later remotes not working and truck warning that emergency brake is on even though it was released. Could not get to register that emergency brake was off and while driving none of the turn signals were working as to truck warning to pull over due to vehicle emergency brake was on. I have only made one payment on this new vehicle and truck has already been in shop 2X.I need your help, please as dealer not helping me and I do not feel safe in this truck. I should not have to worry about it turning of or anything else as to being a brand new vehicle. I have attempted to speak with several managers and one just stated to me" that is why you have warranty and just keep eye on it." Since all this I have searched on the internet, and discovered that this has happened with other Silverado.. ed bozart chevrolett still claims no knowledge of this. Please help me. I feel this is potential accident issue. The first issued happened while driving on craig road which could have been really bad as this is a 45 mph road, luckily it was a weekend and not busy. I don't know what else to do. Spending over $40,000 on this truck not expecting to feel unsafe while driving.

On Monday October 5, 2015, I was driving truck at approximately 60 mph on highway when suddenly all electronics went black and complete loss of power on highway. Luckily, I was able to pull of to side of road. I turned the key to off position (engine was not running) and waited several minutes then turned truck on and it started. The traction light kept coming on and off but the truck did not loose power again-thankfully. I could have been killed or caused a serious accident.

Use this truck for commercial purposes to haul trailers. Truck has turned off while driving 4 times. Three while driving with trailer when it hits rough road or under construction road and takes hard jolt to front end. First you are driving, then you hit bump or dip in road and you notice you have no steering, when you look down you notice whole display is shut down ( like it was never on) with no warning lights displayed. You have to put truck into neutral while driving and restart. Last time it happened had 30 foot trailer on truck and were in a downhill position with a turn and no steering capability ( no antilock or trailer brakes because they need electricity to operate)and 300 ft from going off embankment and then dropping 100ft into a gully. The trucks whole electrical system turns off shutting down everything in the truck. Own 7 trucks and have owned 20 plus trucks over the years. I have had design flaw issues and just fluke issues that just happen to that one truck. This really seems more like a design flaw, either in ignition with their new keys ( have a 2012, this ignition is defiantly different) or the electrical system, or maybe they added some sensor that shuts truck off if in a front end impact. If I am right this will kill someone, the truck gives you no warning before turning off and most people are unaware they can shift a car into neutral and restart while driving and since it has happened while pulling trailers this is very dangerous not just for the driver and passages of the vehicle but every other car or truck on the roadway with it. Example of this, the last time when we could not steer and could not go with the turn of the road, there was a car in the second lane and the trailer went into that lane, the car had to make evasive manuviers to avoid impact with trailer.

I am in a situation where I bought a 2015 diesel truck and two weeks later it broke down out of state in Colorado while on vacation. We spent the night on the highway as the truck was in limp mode and the check engine light was on. The out of state dealer pressured us into getting their new diesel truck because they could not resolve the problem with the diesel exhaust in 9 hours we waited at the dealership stranded. The truck was 15K more than the first truck but I am upset they made us responsible for the 1800 miles on the new truck that broke down a week after buying it! the second truck also broke down a couple of days later with the same engine codes as the first truck. This is apparently a defect with this years diesel and we should not be penalized. We need help asap as we are being strong armed into the second truck as the first dealer does not want to do a buy back of the original new truck that broke down in Colorado and left us stranded. The first dealer nor the second dealer did not offer us road side assistance, loaner vehicle or offer us any type of resolution while we were stuck at the dealership. I opened a GM case 5 days ago and still have not had any resolve and the second truck is still at the Chevy dealer and they don't know what's wrong with it. The dealerships say its a GM issue but they represent them and also have the power to make our loan fair given the circumstances or put us in a new truck. We don't think it's fair that they roll in the negative equity of 5K in our loan as per the GM todd at freeway Chevy he told me there are known issues with these diesel trucks and that I am not the first customer to experience these problems. They are still selling them though and need to take care of their customers by offering solutions instead of passing the buck. Our GM case number is please help.

After sitting for two days, I went out to start my 2015 Chevrolet Silverado to drive to town and it was dead - no power, lights, horn, ignition, nothing. The vehicle was absolutely stone cold dead. Having two decades in the car restoration business, I grabbed my battery charger and hooked it up and charged the battery for 4 hours. Attempting to start the Silverado again resulted in the same thing - stone cold dead. I swapped the batteries to no avail. The vehicle still wasn't powering up. I looked for blown fuses, loose connectors, all with negative results. I had the truck towed to the dealer 106 miles away. The next day the dealer advised it started right up after a jump start. My reply was that is simply incorrect and I repeated the steps I went through. They replied they wished to keep it for a few days. Ultimately I had to trade the vehicle because the dealership stated the truck wasn't designed to operate in a dusty environment. My reply was that I bought it to use on my ranch and they knew that to begin with. They advised the dust permeated the body control module, engine control module, and human interface and today's trucks simply are designed for that.

This is the 10th time this has happened, and 3rd time the vehicle has entered the service center. Own a 2015 Chevy Silverado 1500 crew cab Z71, and when attempting to start the vehicle, it does not turn over, indicating that there is a theft deterrent issue. The first time the dealer was unable to replicate the issue or error code. The second time several error codes were present, which the dealer reset. This appeared to fix the issue, until 1 month later the issue presented itself again. The vehicle is currently with the dealer on it's third repair attempt. This can be very unsafe for a vehicle since in an emergency need the vehicle could be incapable of being driven.
