  1. Ok. I hope I’m doing this correctly, this is my first post. 2015 Silverado LTZ with a cat pee smell in the interior that goes away quickly when any type of ventilation is on or windows are open. I crawled around the interior sniffing everywhere. I first thought it might be the Chevy brand “Weather Tech” style mats, but no. Not from the vents and i replaced the in cabin filter. The smell is coming from under the sliding sunroof shade and I figure it is the grease or lubricant that is used on the sunroof sliding mechanism. It has the same smell as transmission fluid. I knew I had smelled this before. Just going to put up with it since it doesn’t linger. Cats have been falsely accused.
  2. 2014 Silverado going in to service on monday for antifreeze smell in cab with heat and or on auto...Has anyone else had issues? As of last Monday there were 29 heater cores ordered by gm dealerships, (wife works at gm call center, had her look it up) no special notes from dealerships on the order.. seems like alot for a part that shouldnt have to be replaced very often..Will keep everyone updated on diagnosis from Gm dealer...
  3. I've noticed when i return home from a drive and the truck has been up to operating temp, there is a burnt rubber/plastic smell coming from the truck once i shut it in the garage. Seems like it was strong when i took delivery of the truck a month ago, and still seems strong today. Doesn't smell like it's from the wheels/tires/brakes, so i'm thinking engine bay/drivetrain are only options. Anyone else notice this smell if you shut your truck in the garage after running? Thinking it could be any of the following: Heat Shield burn in engine bay Plastic part too close to a hot metal part, Intake manifold too hot (assuming intake manifold is a thermoplastic) something in catalytic convererters still burning in It is definitely not a burnt oil smell and i'm not smoking the tires, just normal driving and i smell this in the garage after 10 min. Any ideas or similar problems?
  4. Good morning everyone, This is my first post ever, and the first time I have "started a thread." I am reaching out because I am having an issue with my 14 Silverado All Star edition, and I just dropped It off at the Dealer I bought it from today. This truck is my first Domestic purchase over the past 20 years since I started driving. I have always had Foreign, mostly German cars, and I have been working in Dealerships basically since I was in High School. I also have never worked for a Domestic manufacturer, maybe that's why this is the first Domestic product I have bought. Everything started about a week ago when I got into my truck to leave work and I immediately noticed a strong gas/fuel smell in the cabin. At first I thought it was a car in front or behind me, maybe even the area I was in, but the smell was there for the entire 30 minute ride home. Over the next few days the same thing happened several times. Over the past weekend I popped the hood and it was like a punch in the face! The fuel smell was definitely coming from the engine bay, and right into the cabin. I tried putting the A/C on, rolling down the windows, and shutting off the outside air. Didn't make much of a difference, still too strong to drive around. After talking to a few of my Techs at my store, and other people in the Automotive industry, I found someone at a Chevy Dealer that told me there was an "Internal Bulletin" from the manufacturer that said there could be some 2014 models with a this concern. The bulletin has not gone public as of right now so not many people have heard of it. Even the Chevy store across the street from my store had no clue. But luckily I found someone at the Dealer I bought the truck from that actually cared enough to do 60 seconds worth of research. I have heard stories of injector seals not seated correctly and fuel is actually coming out from there, also maybe the fuel pump on the motor has a leak, but not sure yet. Hopefully I will hear soon as to what the Dealer found so I can get my truck back and not have to drive a Chevy Cruz that barely fits two people comfortably. So I am wondering if anyone has had any experience with this... And if anyone is interested I can keep you posted as my situation progresses.
  5. I have a 01 Silverado 2500HD long bed and it seems for the past while a bad smell has progressively gotten worse, it is the strongest in the rear driver wheel well. The burning smell I've been told is from my park brake which I use quite often, is this commen for them to get stuck and still drive? It stinks the most after I drive it for a bit. I've also been told it could be the rear diff but I just changed the fluid, they are also disc brakes in the back.
  6. Wondering if anyone has experienced this issue or if there is something I should look at specifically under the hood... I have a 2015 Sierra SLT 4x4 Crew Cab with 18,000 km on it, and recently when idling or stopped at a light etc. a strong sulphur smell comes out through the vents, and can also be smelt in the engine bay with the hood open but only intermittently. I took it to the dealership where they ran a full check of all sensors, coolant system, battery and visually inspected the exhaust system for any holes and everything came back normal. Of course when they test drove the vehicle, the tech couldn't smell anything either. I picked it up, and the issue returned so I took the tech with me around the block where he could then faintly smell it as well. He replaced the cabin air filter and washed the bottom of the truck in case "burning road grime/dust" was to blame (which I highly doubt). I crawled under the truck today armed with soapy water and couldn't find any leaks on my own and came up empty handed. I took a few pictures of where the headers connect to the down pipe, and the drivers side bolts/flange looked separated compared to the passenger side. I'll be taking the truck back to the dealer again in hopes of recreating the issue once more, but does anyone have an idea of what might be causing this? All the bolts on the headers look to be intact and snug as well. Any insight would be greatly appreciated!
  7. I have an '03 Avalanche w/93.8K miles. Got out of the truck at the grocery store and immediately got hit w/a very strong burning odor. Original thought was electrical, so took a flashlight in my pocket and looked for smoke in the cab. There was none. In fact, I couldn't see any smoke anywhere. Smell had dissipated while in the store, but upon arrival at home (2 miles away), there it was again. I sniffed around and found that it was strongest around the left/rear wheel well. Hoping someone else has had this issue and been able to resolve it. I cannot find any recent posts about anything similar that have any confirmed solutions posted. Thanks in advance, I really LOVE this truck!
