problem #69

Jan 032018

Avalanche K1500 V8

  • Automatic transmission
  • 62,500 miles


This problem occurred with only 62,000 miles on the vehicle. I would think the engine should last at least to 150,000 miles.

problem #68

Avalanche 5.3L

  • Automatic transmission
  • 30,000 miles

Purchased this 2007 Avalanche in the fall of 2006. By early 2009, while still under warranty, oil was burning excessively and white smoke was emitted from the exhaust upon most cold starts. The dealership "fixed" this problem under warranty by changing some plugs, rings, etc. Approximately 6 months after the "fix" and 3 months after the warranty expired, the problem returned. Told it was a totally separate issue, I needed new lifters to the tune of about $2000. This repair held for approximately 2 years, at which point the same problems began to present again. I then took my vehicle to the dealership that purchased the previous dealership (where I had purchased and repaired it). The new dealership told me I just needed a new engine, because, "through nothing you did", oil has not been getting delivered at a high enough rate. They told me things like "we see this all the time" and "the new engines have it fixed". Because the new dealer had "lost" all service documentation from the purchased dealer, I pushed and ended up splitting the roughly $6000 cost with them. This new engine came with a 36 month warranty. In month 37, the new engine, which I have since learned had the same or even more problems than my original, needed new lifters, again to the tune of $2000. Now, 18 months later, we have the lifter issue again with not enough oil being delivered.

GM, as many of you know, is unresponsive to customer issues and sends them back to the dealer. When I last had this issue, the dealer's only solution was to offer me a trade for another Chevy vehicle, which does not sound like something I would like to own at this time.

Avalanche LS 5.3L V8

  • Automatic transmission
  • 137,904 miles


The third time this happened, it caused my truck to shutdown and I had to coast it into a parking lot as I was on my way to work. Ended up having it taken to Certified Auto Repair and Service here in Spokane Valley Washington and they found out that the Mass Air Flow Sensor was bad and a couple other things that were bad and had to be replaced including new spark plugs. Found out that the previous owner put in standard plugs instead of flex fuel plugs. This is ridiculous that this keeps happening.

As I can see from other people, this is an ongoing issue that Chevy should put in for a recall. Get off your lazy ass and investigate why your vehicles are becoming sh*t! I had a ford with way more issues wrong but the engine was strong. This engine is strong, but come on fix your sh*t. At my job, I have to do everything right the first time or I get fired. Why can't you do this as well Chevy?

This is the 2nd of 3 complaints about the excessive oil consumption issue. So now we are not even 2 weeks later and the same issues happen. Engine Oil Low Add Oil popped up on the instrument dash yet again. This time had to add 1.5 quarts of oil. Called Dishman Dodge again. Stated the same thing and to call Chevy. By this time I am irrate because I am stuck in Montana.

Avalanche LS 5.3L V8

  • Automatic transmission
  • 136,354 miles

So, this is the first of 3 complaints about this vehicle for the same issue. 3 weeks after purchase of the vehicle, the command center screen on the instrument panel lit up stating "Engine Oil Low. Add Oil." I pulled into a parking lot where I proceeded to call the dealership, Dishman Dodge in Spokane Valley, Washington, and told them of the situation. They couldn't help me because their systems don't sync with my Chevy. So I had to call the Chevy Dealership to get any help. They told me to wait about 15-30 minutes to allow the oil to drain from the heads to the oil pan, there was no oil on the dip stick. Waited for this to happen. Had to add a full quart of oil to the truck. Fixed the issue for the time being.

Avalanche LTZ Z71 5.8L

  • Automatic transmission
  • 55,000 miles


I bought my 2007 in late 2009 and noticed right off the excessive usage. Had it tested and no help from the dealer when I was told the engine burns oil that way. No recalls or anything. Now, I am closing this complaint to open another regarding the transmission.

Avalanche LT 5.3Liter

  • Automatic transmission
  • 114,000 miles

I bought my 2007 Chevy Avalanche new ever since I can remember the oil would be a bit low when getting an oil change, I use only Mobile 1 full synthetic oil and change it at around 4k miles never let the oil life monitor get under 30% at around 100,000 I noticed the oil consumption increased and engine performance decreased. So I changed spark Plugs and wires and noticed the rear sparkplugs were we a bit oil soaked. I started looking into this issue and found online that other people were having this issue and it is related with Active Fuel Management system and Aggressive Lifters. I took it to the dealer and of course it was not under warranty and I didn't want to spend thousands of dollars for them to tear apart my engine and install new lifters and so forth. I asked if this was this a common issue and they said it's normal for these engines to burn oil. So I found online a device to deactivate the Active Fuel Management and now my truck doesn't burn oil it barely drops from where I fill it when doing the oil change and the MPG is almost unchanged. So this AFM system is not really something that I see necessary when driving in the city maybe when doing Freeway driving it helps with MPG. I see this as a design flaw in the way the AFM system works and the manufacturer should've had a recall on this problem.

Avalanche LT 5.3L

  • Automatic transmission
  • 15,000 miles

Brought this vehicle brand new 10/07. The following year the oil light came on. Took to dealer was told it was a new truck and it burns a lot of oil. This problem continue on and off for the next few years. There was a hole in the oil pan, was fixed. Same problem started again. Finally white smoke started coming from engine. Dealer told me I didn't do regular maintenance on vehicle. After providing written proof dealer kept vehicle for 21/2 weeks. Was never told what the problem was.

A year later oil light comes on again and now the oil pressure gauge is moving all over the place. The vehicle has 140,000 miles on it and now it sits in my drive way because the engine block is cracked due to the oil leak problem. The cracked engine block was this year 2016. The reason I brought the 2007 Avalanche was because I had a 2001 Avalanche had no problems with it. So I brought another one so much for brand loyalty. There were other major problems that I have had with this vehicle.

Avalanche LS 5.3L V8

  • Automatic transmission

We definitely were a Chevy family, but after other issues, including the transmission needing to be replaced (we only had the truck for less than a year) and now this. I am no longer going to buy GM vehicles. It's very disappointing that GM would not take responsibility for repairs with a recall.

Avalanche LX 5.3L

  • Automatic transmission
  • 92,000 miles

After 4 previous complaints on oil consumption, they finally listened when we used 4 quarts between oil changes. They found two cylinders fouled and suggested valve and ring job. I cautioned them referring to Murphys Law, regarding the other side of the engine and I wanted it noted that the vehicle was still under warranty when they chose this decision. Numerous calls to GM finally resulted in them OKing a new engine. Customers mere very satisfied. Now have 50 K on new engine, all is OK.

Avalanche LTZ 5.3L

  • Automatic transmission
  • 81,200 miles

I change my oil and oil filter myself so that when I change it right after it has the right amount of oil in it. I use Mobil One 5w-30 synthetic and a Fram oil filter. And it doesn't fail, I have to add two quarts between oil changes, so not only a pain, but additional cost on top of the problem. I don't drive my vehicle hard or put excessive miles on it. Is there any thing that can be done? Chevy, I might start looking at Dodge when next vehicle comes around.

  • Automatic transmission

Our Avalanche needs at least a quart of oil every 1000 miles. We just obviously carry oil when contacted the dealership just acts like this is completely normal for a truck. I think they should have put it in the owners manual since this is apparently the case after 75,000 miles. Maybe they should make a special place to carry oil in the back and an easier fill pipe since this obviously the plan.

Definitely burning oil! I'm not sure exactly the issue but it seems like a lot of other owners are having the same problem! I would gladly endorse any legal action taken to correct the problem with this engine!! For now i'll keep driving and keep adding...smh!

Avalanche LTZ 5.3L V8

  • Automatic transmission
  • 90,000 miles

I bought this truck in april of 2014 . I had to help move my daughter to college and when we got there the low oil/add oil came on. I checked it after I let it set for a few and there was nothing showing on the dip stick. The dealership has since done 2 oil consumption tests and each time they tell me its within specs on oil consumption meaning they are saying that 2 quarts low every 3000 miles is within specs. That's just BS to me and seems to me that they are using the within specs to get out of fixing this problem. Its October 2015 now and I've been dealing with it since I've bought it. GM called me today cause I had filed a complaint with them and the lady told me there's been no complaints brought to their attention with this issue . I laughed at her on the phone and told her to stop lying. I've read bout some of the possible fixes for this issue . I bet GM put out the literature to these fixes but just don't want to pay to fix these defects. I'll never buy another GM after this.

Avalanche LT 5.3L

  • Automatic transmission
  • 210,000 miles

I love my Avalanche. I hate GM stopped building them. However, I have read a lot and seen numerous complaints about oil consumption. My Avalanche has always used oil, no leaks or smoke. I always changed my oil between 3000-5000 miles. I do have a lot of miles on it, but she has been maintained, highway miles. I am in the process of replacing both heads and lifters due to a tap in the top of motor. Was getting p0300 code, and two cylinders were misfiring due to valve problems. In my research, I have discovered this is a problem that has been going on with these 5.3 engines, but apparently GM says nothing. As I said, I have a lot of miles on the truck, but hey I still drive a '65 Galaxie and '66 Mustang. Age doesn't matter, if the vehicle is cared for.

Avalanche LT 5.3L

  • Automatic transmission
  • 70,000 miles

Bought my 2007 Chevrolet Avalanche LT 1500 brand new and fully loaded. 5 years later I start getting a low oil light add oil with still 60% oil life. Take it to dealer and they start giving me the run around the dumb associates said that I should check the oil every time I put gas, as if anyone really does that or should that specially with a new $46,000 vehicle. Called GM and they give me run around also. Keep wasting my time.

My truck is 8 years old now and I have to continuously add oil when the light goes on. I have been living like that for a few years now. Someone once told me to never buy the first year model of a new vehicle but I didn't listen.

I have really thought twice about ever buying another Chevrolet vehicle. I like my truck but hate that GM will not step up and take responsibility for the problem. All they have to do is Google Oil Consumption Issue for 2007 Chevrolet Avalanche and there are many complaints.

I am currently in the market for a new hybrid vehicle and waiting for the redesigned 2016 Chevrolet Malibu or the redesigned 2017 Ford Fusion Hybrid. Really leaning towards the Ford Fusion because of the GM won't step up and fix my issue.

Also would like to add that I have a GM Credit card with almost $1,500 in rewards towards a new GM vehicle and I am still leaning towards the Ford Fusion.. GM step up and take care of your issues..

Avalanche LT 5.3L

  • Automatic transmission
  • 30,000 miles

Bought truck new and has been using oil since about 30000 miles.Had a few repairs done but never fixed the problem. Now out of warranty and with 73000 miles on it extended warranty will not pay for carbon-ed up oil rings.It is now using 1 quart in 850 miles and they will only pay if there is something broken.Dealer wants $3600 plus to replace the pistons and rings. It should not be up to me to pay when Chevy knows this is a common problem and I have been having it all along. Has anyone had any luck with this issue?
