However, it still has a known issue in the cold, which has not been fixed. ## **GM 3.0L Duramax diesel known problem** What issue am I referring to? The high fan speed after plugging in the truck. A few years ago, I discovered this issue myself with a [2023 Chevy Silverado 1500 High Country]() I bought for a longer review. According to the owner’s manual, I had plugged the truck in at below-zero temperatures. When I was ready to leave, I unplugged the truck and started it up. The engine fan started running so high that it was very noticeable outside the truck. I assumed it was just a fluke and that it would calm down the more I drove it around. It did not calm down. I drove 90 miles that day and made multiple stops with varying lengths of time, up to an hour, with the truck off. Each time I started it up, the fan went to high. I tried remote start as well to no avail. I made a video on it and figured it was a software fix for GM and they would take care of it. However, I was recently on a [LZO Duramax diesel Facebook group]() and numerous owners are stating it is still happening. With a recent cold snap hitting most of the country there were several posts a day on this topic. The only fix is to disconnect the battery cables which forces the truck to do a hard reset. Then, the fan resumes its normal operating behavior. Easy fix for the owner, but not something you really want to do when it is bitter cold outside. Our take These are the kinds of things that annoy new truck buyers. They even wait until all the “bugs are worked out” only to discover the bugs are still there years after a new truck has been launched. ## Structured page information ~~~json [ { "@context": "https://schema.org", "@graph": [ { "@type": "Article", "@id": "https://pickuptrucktalk.com/2025/01/gm-3-0l-duramax-diesel-known-problem/#article", "isPartOf": { "@id": "https://pickuptrucktalk.com/2025/01/gm-3-0l-duramax-diesel-known-problem/" }, "author": { "name": "Tim Esterdahl", "@id": "https://pickuptrucktalk.com/#/schema/person/82b06f99329f69a069a5ab6caed18593" }, "headline": "GM 3.0L Duramax diesel known problem in the cold with no fix", "datePublished": "2025-01-24T16:22:32+00:00", "dateModified": "2026-07-19T02:08:53+00:00", "mainEntityOfPage": { "@id": "https://pickuptrucktalk.com/2025/01/gm-3-0l-duramax-diesel-known-problem/" }, "wordCount": 345, "commentCount": 0, "publisher": { "@id": "https://pickuptrucktalk.com/#organization" }, "image": { "@id": "https://pickuptrucktalk.com/2025/01/gm-3-0l-duramax-diesel-known-problem/#primaryimage" }, "thumbnailUrl": "https://pickuptrucktalk.com/wp-content/uploads/2025/01/2024-gmc-sierra-001-copy.webp", "keywords": [ "Chevy Silverado 1500", "Chevy Suburban", "Chevy Tahoe", "gmc sierra 1500", "GMC Tahoe" ], "articleSection": [ "Buyer's Guide", "Engine Reliability" ], "inLanguage": "en-US", "potentialAction": [ { "@type": "CommentAction", "name": "Comment", "target": [ "https://pickuptrucktalk.com/2025/01/gm-3-0l-duramax-diesel-known-problem/#respond" ] } ] }, { "@type": "WebPage", "@id": "https://pickuptrucktalk.com/2025/01/gm-3-0l-duramax-diesel-known-problem/", "url": "https://pickuptrucktalk.com/2025/01/gm-3-0l-duramax-diesel-known-problem/", "name": "GM 3.0L Duramax diesel known problem in the cold with no fix", "isPartOf": { "@id": "https://pickuptrucktalk.com/#website" }, "primaryImageOfPage": { "@id": "https://pickuptrucktalk.com/2025/01/gm-3-0l-duramax-diesel-known-problem/#primaryimage" }, "image": { "@id": "https://pickuptrucktalk.com/2025/01/gm-3-0l-duramax-diesel-known-problem/#primaryimage" }, "thumbnailUrl": "https://pickuptrucktalk.com/wp-content/uploads/2025/01/2024-gmc-sierra-001-copy.webp", "datePublished": "2025-01-24T16:22:32+00:00", "dateModified": "2026-07-19T02:08:53+00:00", "description": "The small diesel is a fuel economy champion and one of the best engines GM has built.
