2007 CHEVROLET SUBURBAN Complaints

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 for some more power, and it fails. Ruining the rest of the engine with it.

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.

There is an electrical problem with driver side door harness which causes my car not to start causing me to have to keep replacing the fuel pump from malfunction of ground wires leading to the fuel pump and ECU from what I am told

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. Most are simply taking it on the chin; paying out of pocket or doing the work themselves to repair, delete, or modify the engines. I understand there is time and the age of the vehicles against these claims, but acknowledgement and shedding light on this known issue from General Motors will help just as much.

Cracked dashboard. Continues to get worse. Cracks get bigger and more cracks appear.

My suburban 2007 drains battery overnight, tried different alternator and batteries but continuously drains battery’s.

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 two problems deal with my problem with heat. The a/c runs intermittently and sometimes only blows very hot air. Also, what a big reason I purchased a Tahoe LTZ and this vehicle was because of the remote start which is not working. Is there anything that can be done. I needed a safe vehicle for my short regular trips and I've become worried and I have already had to rent a vehicle to make the trip out of fear of the cabin getting so hot. With Narcolepsy I can fall asleep without warning. Please advise. I'd love to keep the truck but not if it could mean injuring someone else or myself. Thanks in advance.

The contact owns a 2007 Chevrolet Suburban. The contact stated while driving 50-60 MPH, the check engine warning light illuminated, and the vehicle started jerking. Additionally, the contact noticed that there was white smoke coming out of the exhaust pipe. The vehicle was taken to Triple A service station, where the cause of the failure could not be determined; however, unknown plugs and wire were replaced. The contact stated that the failure recurred several times while driving. The vehicle was taken to an independent mechanic, where flour coil packs were replaced; however, the failure persisted. The vehicle was taken to the local dealer, where it was diagnosed that intake lifter of cylinder #1 was not moving due to a collapsed lifter roller, which lead to oil built up on the oil pan and the rear main seal. The dealer determined that engine needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 185,000.

The engine has a collapsed lifter that has failed. This problem is placing us at risk of breaking down while driving. I live in a busy city that has a lot of traffic. When I have money, I plan to take the vehicle to the dealership to confirm. I first noticed the problem by hearing the engine make a clicking sound when the engine is running. The sound is coming from the area of lifter location.
