For those driving Chevy diesels, there is an ongoing problem with DEF heater failures. GMC has extended the warranty on these parts for 10 years. My 2015 Chevy DEF heater failed in year six at 27k miles. Thankfully, the extended warranty saved me about $1000 bucks.

DEF problems are not just a Chevy problem. With all the technology they pack into these trucks, you'd think they would be able to fix this issue.
