general problems of the 2007 Chevrolet Suburban

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.

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.

The engine began smoking really bad when driving down highway and car locked down. It became undriveable. I was out of town when happened and had to have towed. Mechanic confirmed motor is bad and has to be replaced. Just had transmission replaced 2 weeks prior to this happening. Transmission has had to be replaced 2 x's since I have owned vehicle.

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.

Took a left turn while driving, heard a small noise and with in one minute of going down the road after my turn, my engine was a rough idle, engine light blinking and traction control was blinking. Had it towed to the closest chevy dealership to find out that the lifters were bad and causing misfire. That's a common problem for this engine and the replacement cost should not be on the consumer, there should be a recall for this costly repair!.

Engine is malfunctioning and using excessive amounts of oil (1 quart every 1-2 weeks). The manufacturer built bad motors in 2007 and knowingly covered it up. The vehicles were still sold to consumers and rather than fixing the issue (engine would have to be rebuilt or replaced) the manufacturer is placing all responsibility and cost ($9,000 fix) on the consumer, even when reported before 100,000 miles. The manufacturer knowingly sold lemon vehicles and refuses to fix. A mechanic told me that my engine could explode (severe safety issue).

Tl the contact owns a 2007 Chevrolet Suburban 1500. While driving 45 mph, the check engine, stabilitrak, and stop engine now warning indicators illuminated.

The contact stated that the spark plugs, ignition wire, and oil sending unit were replaced; however, the failure recurred. The manufacturer was notified of the failure. The approximate failure mileage was 156,000.

We have a 2007 Suburban with the 5. 3l engine. After, much research on the internet, my wife and I have found that there evidently is a design flaw with the afm lifters. Our vehicle does have miles, but since this evidently is a very common problem, we did think Chevrolet would at least offer some assistance with the repair. A lifter collapsed and the cost to replace the lifters is $3,500. 00, plus tax at tom gill Chevrolet in florence, ky. I don't blame the dealer for this, but Chevrolet has really dropped the ball on this issue for many, many vehicles with the same issue. Something should be done to better protect the consumer.

While this was/is a used vehicle, and while the mileage is high, the sheer frequency of the exact same complaint dictates that this is a problem that frequently occurs. Further exacerbating the problem is that gm and its dealers have no incentive to fix the issue as a full engine replacement is what is being offered as a solution. I was quoted by my dealer that the costs for this is (~)$8,000. 00! as is the case with the others that have complained about this: I was driving along and the oil pressure went to zero. After taking it to the dealership, they replaced a few components and sent me on my way (after getting a large bill of course). We use the car very infrequently and as such, within a 100 miles of use, I was back at the dealer with, again, very low oil pressure. There recommendation was to replace the engine at $8000 or perform an overhaul at 2000+ with no guarantee or warranty. This is ridiculous. From a cost standpoint: the Suburban is a $60,000+ vehicle, and the problem is not fixable/resolvable, other than by gm asking for an additional $8000. From a safety issue, these cars are heavy, big, and can cause much damage if the driver is distracted by such a large engine problem and/or the engine shutting down due to the engine block freezing up and/or seizing due to the lack of oil pressure. Now, and especially in light of gm¿s refusal to acknowledge the safety recall associated with its ignitions, I think there is sufficient cause for the NHTSA to take a hard look into this, open a full investigation, and hopefully rectify this for the hundred (and possibly thousands) of consumers affected and force gm to address these issues, both with respect to its existing/past sales, as well as address its future designs.

The truck uses a quart of oil every 1000-1500 miles. This is not good for the enviornment or my wallet.

Our vehicle started to use bewteen one quart and 2 quarts between oil changes. At sometime before this the heater stopped working on the windshield washer fluid. The dvd player stopped working around 75,000 miles. At 79,0911 miles the service air bags light came on. We are not new to owning Suburbans. This is our fifth one. We have always been happy with them, but this one has way to many things that are not working properly. We would like to hear from you regarding resolving these issues.

2007 Suburban vehicle came to a stop 25ft behind several stopped cars at a red light. Without provocation, the vehicle strongly accelerated/surged forward while the brakes were engaged. Driver continued to attempt to stop the vehicle by repeatedly hitting the brake pedal, but with no success. Passenger in vehicle reported seeing drivers foot on the brake. Vehicle accelerated forward into the back of another vehicle which was then pushed into a third. All three vehicles suffered damage. Airbags failed to deploy in Suburban despite level of impact. Vehicle was taken to Chevrolet dealer for complete diagnostic. Results inconclusive; no data errors recorded in computers and no apparent mechanical attribute could be found relating to vehicle action. Action could not be repeated by technician. Vehicle released to owner. No explanation could be given as to this action. Dealer did not follow up or continue investigation.

I purchased my Suburban with existing gm warranty. The vehicle had roughly 47,000 miles on it and 7 months remaining of the original factory warranty. After about 900 miles the low oil light came on, which I thought was odd because I checked the oil life gauge after purchase and it said it was at 99% oil life. This worried me. It was one quart low so I added it and decided to see what happens. A month later at about 1000 miles the same thing happened. I added another quart and then went to the dealer closest to my home to report the issue. They started monitoring. Each time at between 900 and 1400 the oil light came on and I was a quart low. They began remediation. First the pvc/valve cover remediation. This did not solve the problem. Then next the oil pan related remediation. This did not solve the issue either. Now I keep having to take the Suburban to the dealer when the oil light comes on, they add a quart and say there is nothing they can do, from a legal stand point because I have an extended warranty and the car is out of gm warranty (remember I reported this while it was under gm warranty and reminded them of that), that gm won't do anything more from their experience with this issue. However, they have not contacted gm or opened a case file and wont do that. I was told I will need to pursue that on my own. They tried to reach out to my extended warranty but say they are put on hold for 10-15 minutes and have to hang up because they are too busy to wait longer. I've called them repeatedly asking that a case be opened with gm as this was reported under warranty and is a known defect with this engine (I'm out of warranty now) but they just keep giving me the run around. Gm needs to do a recall and address these engines.

I bought this vehicle used, the day I got it home it suddenly had no oil pressure. Chevy dealership put a "patch" on its boo-boo and sent me home. Now at 140,000 miles I once again have no oil pressure. Chevy says I need a new engine and of course I'm no longer under warranty. Approximate cost $6,700. This vehicle left me stranded on the side of the road twice. I have found hundreds of complaints of the exact same issue (same year, make and model) I'm having and Chevrolet has yet to issue a recall on this defective motor. The company returned correspondance with me and informed me that their "calculator" says they cannot offer me any assistance. I now have a 4 month old son and over a foot of snow expected in my area over the next 24 hours. What happens if he is sick and I have no means to get him to a doctor becuase of this issue Chevrolet won't own up to?.
