problem #9

Jan 032018

Avalanche K1500 V8

  • Automatic transmission
  • 62,500 miles


I have checked the internet about this problem. It seems that the 2007 Chevy Avalanche is known for having bad lifters, I think Chevy needs to have a recall on the 2007 Avalanche. Does any out there know who I can contact to have Chevy pay for at least half of the repair costs to this vehicle ?

Avalanche 5.3L

  • Automatic transmission
  • 185,000 miles

Engine misfired or Cylinder one broke down. I think GM should pay for to repair cause it is GM built.

Avalanche LS 350

GM should have covered this, they refused and it sounds like a ongoing problem.

Avalanche LT 5.3L V8

  • Automatic transmission
  • 113,500 miles


I have been a Chevy guy my whole life. This turd has changed that for good, it has cost me time, money, and a butt load of frustration. Started with oil pressure gauge failure, "well crap, that sucks", replaced the sensor, back in the game. Three days after I changed that, oil pressure dropped and I got the blinking light of doom. WTF, turned truck off, checked oil and saw no reason for low pressure. Started truck again, normal oil pressure, hmmmmm. Drove home, and to work the next day, on the way home all started well, then the first stop light off highway, was idling really rough, service trac control, service stabilitrac, check engine light. Drove on, trans was shifting roughly and like backfiring and running with reduced power, "NOW WHAT MOTHER F%&*(&".

Did some checking and found no compression on number 1 cylinder, "OH SH!#". Took the head off thinking I would find an obvious problem, no. Called some help who said it could only be a valve lifter holding the lifter open,?????? "okay". Changed 2 lifters at $55 each active fuel management cylinders. Low and behold it works, yeah. Two days later I have a collapsed lifter and I would have to pull the head AGAIN. Next vehicle will not be a GM, this is only the worst of the many issues I have had with this mistake of a truck.

Avalanche LS

  • Automatic transmission
  • 68,000 miles

68,000 Miles and already had to replace the Transmission at 48,000 miles. Had noticed for the last couple of oil changes that the engine was using oil. Had to add a quart 2-3 times before changes. Then one day....Check engine light came on, then the dash text read "Check Stabiltrak" and Check Traction Control", switching back and forth between these two warning messages. At the same time, the engine began skipping & felt like it was not running on all eight cylinders. And I could feel the up-shift and downshift of the transmission while driving at all speeds. I assume the Stabilitrak & Traction Control msgs were just the computer spiking due to the engine failure. I took it to my local mechanic and he told me that there was a known factory defect in the cam shaft of this engine that caused damage to the valves and that the failure was well recognized and documented among auto mechanics.

Spoke to the local dealership, and they said that there was a common problem/defect with the engine rings (so not only the cam shaft, but also the rings). They contacted GM to ask if any "assistance" was available. Since my Avalanche has only 68,000 miles, they said they would "participate" in the fix; however, since it is out-of-date warranty, it would still cost me $2700.00. Indeed, not much because my mechanic wanted only $2500 to do the same thing without any "Assistance" from GM!!!! What a crock!!

Engine & Transmission Failure under 68,000 miles.......What a LEMON!!!!

Avalanche LT 5.3L V8

  • Automatic transmission
  • 55,000 miles

The vehicle is currently at my local mechanics garage. I dropped it off this morning. What happened was that the check engine light came on while I was driving home from work. Then the dash text read "Check Stabiltrak" and Check Traction Control", switching back and forth between these two text messages. While all this was happening the engine felt like it was not running on all eight cylinders. And I could feel the upshift and downshift of the transmission while driving at all speeds. Luckily I wasn't too far from home when all this happened so I limped it home. Next day took it to my local mechanic so he could plug his scanner tool in to read the code or codes it was throwing. Basically said it was a misfire on cylinder number 7. He suggested I check plug number 7 and replace it. The truck only has 55,000 miles on it, but I did a tune up anyways. Changed the spark plugs, wires, and even replaced the ignition coil on cylinder number 7. It all made no difference at all. So now it sits in my mechanic's garage and I'm waiting for his phone call. After this issue is resolved I am seriously going to look into selling it.

Avalanche LXZ V8

  • Automatic transmission
  • 52,000 miles


Was driving 07 avalanche all of a sudden all lights came on onstar did diagnostic and said get to dealer asap. The dealer said had low oil and I told them just changed 1500 miles earlier. After many calls they said 3 pistons were misfiring and it was burnt up with a lot of carbon. After 4 weeks of back and forth with GM they said would replace engine. Finally picked up after 5 weeks at dealer. Had a 2003 avalanche and never had a problem . Now reading this blog wish I had kept it and not upgraded t0 07

Avalanche LS 5.3L V8

  • Automatic transmission
  • 82,000 miles

Continuously misfiring. Replaced all 8 lifters spark plugs and wires. continue with oil consumptions tests... spark plugs continue to carbonize , all before 82,000 miles continue to constantly change the plugs and wires and complain about the trans now the transmission goes for the 2nd time @ 155,000 miles. I own at least 13 Chevy all bought new and no major problems and drove each one to at least 300,000 miles or more. But this is the pits. Chevy claims that this is normal wear n tear --this is not normal !!!!

i bouught this truck brand new and at 32000 miles lost the transmission and now this , just six months after have there mant 2 service and two weeks after a 6k check up engine light comes on and truck idles rough. I take it in and they question my maintenance of spark plugs and the trottle body. I find out i have to get a cylinder head replaced called previous dealer, about the mant but realized that may get me nowhere . So have contacted GM about there truck and how unreliable it is . I t seems there have been a host of problems with the 07's but they are really saying much. I will be screaming from the top of the mountain and start look a other truck not in the gm line.
