5.3L lost compression in one cylinder &...

Postby pennhead [OP] » Apr 30 2013, 2:20am

Past Friday night was raining, drove truck in 4WD auto. Parked overnight, remote start next morning, hopped in and accidentally tapped accelerator bringing RPM's up a little (not a rev), and then inserted key and turned on ignition. Put truck in reverse and loud womp-womp-womp-womp with accompanying vibration from engine. Service Stabilitrack message, Traction Control Off message, Check Engine light popped on. I switched to 2WD, no change. Put truck in park, engine smoothed out some, shut off and restarted, put in gear and same scenario as before. Was somewhat reluctant to go back in park.

GM mechanic told me sounded like it was misfiring. Didn't want to drive to dealership for fear of washing out misfiring cylinders, so had it towed. Got a call and they say need to replace pistons! One cylinder has low-or-no compression and oil-fouled plug. I'm having trouble remembering exactly what he said because I was so taken aback and in shock when getting the news. $3000 to replace the one piston! He said might as well do all for another $600 and basically have a new engine. That would get new lifters, too. I am distraught!

The truck has 89K miles, however is about a year out of warranty. It had an oil-fouled plug in the past and using a little oil, but they addressed that with the splash shield under warranty some time ago. I asked them to see if they can somehow repair this under warranty, so they will be checking into that tomorrow. No promises, they said, but they will check.

I asked how this could just happen so suddenly, and he said it's probably been getting this way for some time. I get monthly diagnostics from OnStar, and there's never been any indication that anything was awry.

I'm sorry about rambling on and the disjointed grammar, it's just that this all seems so incredulous and I am just sick. Any advice or help is greatly appreciated.

Dropping new pistons in doesn't make it a new engine, that's BS. How can they tell that the piston failed without taking the engine apart? Just by doing a compression test? When a piston is causing low compression it must be completely toast and should cause noise aswell. I've seen broken valve springs causing the symptoms you mentioned. I would let them exactly explain how they diagnosed the issue and take some pics if possible.

Hey,

I am really sorry to hear about this and would like to do more research on your vehicle. Could you please private message me your name, address, vehicle identification number (VIN), current mileage, and where you took your vehicle in for diagnosis. This will allow me to look more in depth on your vehicle.

Good news, friends. Service Manager at dealership called and informed me that engine would be repaired courtesy of Chevrolet. Let me tell you, that lifted a heavy burden from my shoulders. Instant relief!

Jessica L., I appreciate your comment and desire to help. Looks like it's taken care of. I will update here as things progress.

I'm going through the same nightmare.
My 2009 5.3l Has the EXACT issue your truck had.
My truck has 85,000 miles (under the 100,000k warranty) but over the date by 1 year 2 weeks.
My dealer is planning on opening the engine monday 01/18-16.
Thanks for giving me some hope that GM might help me out.
Did you truck burn oil before this happened?
My 2009 has burned 1 quart of oil every 1000 miles since new. The "TSB fix" which the dealer performed on my truck at 40k miles did not work, oil consumption continued. Deal said 1 qt per 1000 miles is acceptable.
I hope GM does the right thing and treats me as fairly as you got treated.
Do you have any info that might be able to help me out with like TSB numbers, recall notices or anything that you can think of.
Thank you so much!

I'm sorry, I don't have any TSB numbers or anything like that. That's been almost 3 years ago, and truck is still running well. Like you, my truck has always burned some oil, maybe 2 quarts between oil changes. Even after engine rebuild/repair, it continues to burn about the same rate.

Ok thanks anyway.
Did you have to call GM Headquarters directly or did the service department contact and take care of you with getting support from GM?

I'm not at that mileage yet and don't have those issues yet, and I hope I don't. But here's the deal....this is absolute crap on a truck that costs as much as it does. You hear about so many of these types of issues and just have to scratch your head about GM quality. They should absolutely take care of this problem for you. I think in the future I'm going to make sure I just buy $20,000 or less cars if I want to buy new.... People are encountering these types of things while some still have years of $600/Mo. payments to make. It's crap. Some will say to check the other brands and you'd see the same thing. I think trucks overall are WAY OVERPRICED anyway, but it's because of demand. We have to unite to fight.

And don't even get me started on GM saying ANY OIL BURNING IS ACCEPTABLE, let alone on these expensive trucks. I'm going to offload mine and get a Tacoma soon. I'm so disappointed with GM. I hadn't owned one since the early '80's and figured I'd give them another chance. Shame on me.
