The lifter rod associated with the DoD/AFM system failed, causing catastrophic failure in the engine. This isn't an age issue, this isn't a part that wore out and failed. This car would still be running and driving if that system was never installed. The lifters for these systems are known weakpoints that'll eventually fail. Because of this we lost immediate power in the vehicle and had to immediately pull off to the side of the road on a busy road. I had my local shop take a look and they confirmed that it was a lifter issue. No others have inspected this as this is chalked up to the age of the vehicle. There's no warning for this failure. One second you engine is running great, you apply…

Extensive embrittlement, cracking, and partial collapse of the plastic dash into the space underneath the dash. This cracking extends to to the boundry for the passenger side airbag cover potentially creating a dangerous situation(flying debris) during airbag deployment.

My Suburban locked itself with the keys inside of it. It is available for inspection. I had a two-month baby in the car on an 80-degree day trapped for over 10 minutes. At that young age they have no temperature regulation. I took the vehicle into a local mechanic, and it was confirmed. It has not been inspected by the police, manufacturer, or insurance as we bought this vehicle outright from a Facebook Ad. There was a suspension message that appeared on the dash, and we bought it like that. However, I'm unsure to how long that had been on prior to that. My husband was going to work on it over the next weekend as it was supposed to be a work vehicle for him.

As the current investigation is going for the General Motors engines 2014-2025 5.3L and 6.2L for AFM/DFM. The same is happening with 2007 - 2014 5.3L engines with DOD. I had a 2014 Chevy Suburban with the 5.3L I had to rebuild the passenger side due to a DOD lifter failing. My current, 2007 Suburban is starting to make a DOD lifter tap, again on the passenger side. I will be getting a full rebuilt engine with the DOD system deleted to prevent this in the future. Hundreds have had this happen in the car forums and I can not imagine how many have encountered the same issue but do not say anything due to chalking it up to mileage, age of the vehicle, or just accepting the failure by design.…

My 2007 Suburban has extensive rust that has left the frame open and crumbling. It appears that the seals on the vehicle did not do their job. The spare tire cannot hold under it. I have never taken it into salt water nor has it had flood damage. Its main years on the road were in CT and NJ. I have never seen a vehicle with this amount of crumbling rust. I have to drive 2 hours each way to see my specialists at Shands Hospital in Gainesville every 2 - 3 months and as a female it does concern me that there is that lifter clicking as well as the oil disappears and yet there's no puddle. Also, the lighting in the cabin ac area doesn't function as well as the rear controls. In Florida my last…
