2008 Chevrolet Silverado 1500: check engine light

Filed Jun 28, 2025 · Engine · CA

While driving uphill in my 2008 Chevrolet Silverado 1500, I experienced a sudden and dangerous loss of power, accompanied by a flashing check engine light, ticking noise, and loss of oil pressure. The engine began to shake violently and I nearly rolled backward into another vehicle before I was able to shut it off. After restarting the truck, it began jerking and misfiring, making it completely undriveable. The issue occurred without warning and required a tow. Symptoms Observed: •Low oil pressure warning •Ticking/knocking noise from engine •Engine shaking and loss of power •Jerking and severe misfire when restarted •Flashing check engine light •Diagnosed failed/stuck AFM lifter in cylinder 6 •Engine misfire isolated to cylinder 6 (confirmed by unplugging ignition coil with no change) •Oil consumption and burning smell over prior months •Possible camshaft damage due to lifter failure Shops Involved: 1.Pep Boys (North Clairemont, San Diego) – Charged $400 and claimed to fix the issue, but symptoms returned immediately. 2.Rosecrans Automotive (San Diego) – Confirmed the issue is likely due to AFM system failure (collapsed lifter/cam damage). Estimated repair cost: $4,500+. Additional Impact: •Required towing after complete loss of drivability •Rental car for over a week (ongoing) •Potential lost income due to inability to commute to work •Total cost between diagnostics, failed repair, and upcoming repairs is significant Safety Concerns: •Sudden power loss occurred while climbing a steep hill—nearly caused a rear-end collision •Jerking, misfire, and engine instability made it unsafe to control •No prior warning; failure happened instantly Why I am reporting: This is clearly a systemic issue with GM’s Active Fuel Management system, especially in 5.3L V8 engines like mine. It poses not only a major safety risk to drivers and other vehicles, but also an enormous financial burden on consumers. Based on online forums an

Additionally, a small number of 2007-2012 model year vehicles that include; 2008-2013 chevrolet avalanche, 2008-2009 chevrolet colorado vehicles; 2007-2013 chevrolet silverado, 2008-2014 suburban, and tahoe vehicles; 2008-2013 gmc sierra and 2009-2012 yukon vehicles; 2008-2009 gmc canyon vehicles; 2009-2010 hummer h2, h3 and h3t vehicles; and 2008-2009 saturn vue and 2009 outlook vehicles may have been serviced with a chassis electronic module that could have internal contamination, causing an electrical short in the module. If the module experiences an electrical short, the vehicle could display a check engine light, stall, or fail to start. If the vehicle experiences this condition and stalls while in motion, there could be an increased risk of a vehicle crash. My vehicle has stalled multiple times while driving as well as failed to start. When these symptoms occurred they are accompanied by a check engine light for a u0109 code (loss of communication with fuel pump control module). I believe that my vehicle, although the VIN is not listed, is affected by the federal safety agency recall bulletin number 14515 as quoted above.

Hello, I got a check engine light and found the code is for "low flow, check fuel control module, fuel pump". I found a recall bulletin no.: 14515b date: january 2015 subject: chassis electronic control module internal contamination. It is model year truck and the exact part number of the control module but the local dealer advised gm does not list my VIN as being involved, even though my truck is listed in the model year bulletin and it is the exact part number for all vehicles!! My truck could stop at any time and is unsafe to drive. I can;t drive the vehicle for fear of it stalling and even gm advised it could stall in trafiic and is a safety hazard. Please help. Thank you.

"takata recall". I spoke to a chevrolet dealership person (all star chevrolet north, 9352 plank road, baton rouge, la) about replacing my truck passenger side airbag. I first contacted them on november 7, 2017 and was told the device was not available. I contacted them again on may 10, 2018 and spoke with amanda. Amanda said she would check with her manager to determine if the part was available to schedule the fix but I have not been contacted. I decided to call chevrolet customer assistance center (1‑800‑222‑1020) and I spoke with jane. Jane explained that my vehicle is not part of the recall but your web site and chevrolet web site (http://my.gm.com/recalls) state that my vehicle is part of the 'takata recall'. Jane mentioned something about chevrolet hiring a third party engineering firm that determined that vehicles like mine was not affected. I asked for this in an email or letter but she said she was not authorized to release this information in written form. 'electrical issue'. Vehicle instrumentation panel completely shuts down while driving. This appears to be a common problem when I search the internet. Also vehicle shows the 'airbag' needs serving then right after this the 'check engine' symbol appeared. It is hard to believe that these issues are not related. Thanks.

Takata recall # 16v381. I bought this chevy new and was driving to louisiana. My mileage at the time was 35,955 miles. The red colored seat belt light came on. I was to close to the 36,000 mile mark for warranty coverage to make it to shreveport, la. So I have been driving this truck with the light on. I have asked dealerships if they see the problem, but was asked for a commitment for unknown amounts of money to check and repair this problem. Thank the lord I have not been in an accident with this condition. I want to know if this has been the case with other models as mine. I have a second problem with the engine an transmission. The transmission went out at about 92,000 miles and had to be replaced. Lastly the yellow check engine light has been on. I have spent several thousand to fix this. Even at dealership. I would leave and the light would return. Sometimes I had only driven a mile. I have had other mechanics check it out and it appears I have a lifter problem on my number two cylinder causing intermittent misfires to occur. Is this also a problem with my model?

I have a short in my fuel pump flow control module. It causes my car to stall while while in operation, check engine light comes on, sometimes it doesn't start, etc. This issue has haunted me for about a year now. I found a recall bulletin from gm; #14515b. This is the exact part # and issue that I'm having but my VIN # isn't part of the recall. Is it possible that my VIN was missed?
