When engine is cold you can smell exhaust fumes. Studs in engine are broke. smelling fumes is not a safety issue ? One other thing the battery distribution block was bad and GM knows its bad, they built a new. The truck shuts off wile driving, or does not start till you hit it with a hammer.

The crank shaft broke at 130k miles and this becoming common to this year and model. The mechanic who has the same truck could not fathom this catastrophic failure at such a early life in this truck. This repair is estimated at 5,000.00-10,000.00 and if this does not work the durmax diesel motor will have to be replaced.

The Chevy ac compressor bolt broke before 48K miles while driving on a paved city street in san diego. This failure caused the condenser to also fail and both parts have to be replaced. The total bill for repairs is $2,150.31 and the copy of the invoices is submitted (exclude the fuel filter replacement costs as that was regular maintenance work). The ac compressor failure is caused by cheap parts and is a common problem for all GM products before 100K miles. This should be a recall item as it is a safety risk if the failure result in a vehicle fire or drive belt failure (stranded vehicle) or a loss of Focus while driving.

There definitely a problem with the def & emission sensors on GM's duramax engines. 4th time engine unexpectedly reduces engine power while traveling at highway speeds. Results in sudden speed reduction which is extremely dangerous in almost any driving environment. These "reduced engine power" modes related to monitoring diesel emissions will get someone injured or killed (if it hasn't already)

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.

I bought this truck brand new. I started having problems about 2000 mi. The truck has a miss and jerks under load. It has been to the dealer twice and they tell me the computer doesn't show any trouble codes so there is nothing they can do. Also on occasion the ignition key is hot to the touch. Now I have to take it in again because the brake petal might fall off. What a great product...GM I think builds a lot of these problems in to save money without a care for the customer. Now I have to drive a $46,000 piece of crap thats broken. Our hands are tied and at the mercy of big business. Hope you can help. Steve

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.
