2007 Chevrolet Avalanche Problems

What owners report

Owners of this model year mostly report two things: cracks in the plastic dashboard that spread from the passenger air bag area and the instrument cluster, and a passenger-side air bag warning light that stays on, often in connection with open air bag recalls. Reports of cracks appear from fairly low mileage and are commonly described as appearing in hot weather or after a vehicle has been parked in the sun. Other reports cover engine misfires and oil consumption, stability/traction-control warnings, and rust on the subframe.

1. 1
   Body and structure

   Cracked dashboard around air bag and instrument cluster

   • 111 complaints (29%)
   • median 75,000 mi at 7.5 yrs old (86 state mileage)
   • 3 mention a crash, fire or injury
   • owner-quoted repair $1,200 (median of 7 quotes)
   • filed 2010–2023

   Complaints describe cracks in the top dash pad that start at the passenger-side air bag cover and over the instrument cluster, then spread and sometimes rattle. Owners say the cracks appeared on their own, often after the vehicle had been parked in heat, and some report the dashboard was replaced only to crack again. Several owners say the dealer told them it was normal wear or that repair was not covered once the warranty expired; others had the dash replaced at their own cost. A recurring concern is that a cracked section could affect air bag deployment. Reported from roughly 35,000 to 180,000 miles, with many in the 50,000-100,000 range, often after hot-weather parking.

   What to check: Look closely at the dash above the passenger air bag and over the gauge cluster for hairline cracks, and ask whether the dash has ever been replaced. Parked-in-sun exposure seems to be a common factor, so a garage-kept truck may show fewer cracks.

   2 excerpts from owner complaints in NHTSA records

   “After driving in the summer went inside my house, when I came out the dash had cracked above the airbag area. Also cracked above the instrument cluster. The truck was not moving. The dash has no structure under the center of the dash to keep the dash from flexing. If parking with dash half covered in shade then the dash will be different temps on opposite sides”

   NHTSA complaint #10984830, filed 2017-05, 130,000 miles

   “The dash board on my 2007 Avalanche has several cracks and there are more appearing all the time. This has to be something the manufacture should fix for customers. I have never used any cleaning products other than a wet towel to clean my dash. I'm afraid this could affect my air bag deployment and cause injury.”

   Air bags

   Air bag warning light on; recall parts not available

   • 218 complaints (58%)
   • median 104,500 mi at 9.8 yrs old (89 state mileage)
   • 11 mention a crash, fire or injury
   • filed 2009–2025

   Owners report the service air bag message or air bag warning light coming on, sometimes intermittently for years before staying lit. Some complaints describe a diagnostic code pointing to the passenger-side air bag circuit or a sensor, and several owners say they were told repair parts for the air bag recall were not yet available. Others describe waiting months for a recall remedy, and a few report air bags not deploying in a collision or deploying without an impact. Reported from about 50,000 to over 200,000 miles, with many between 100,000 and 160,000.

   What to check: Check that the air bag warning light goes out after startup, ask for proof that the passenger inflator recalls (21V050000 / 21V052000) were completed, and confirm with a dealer by VIN that no air bag recall is still open.

   “I received a recall and contacted the bud clary dealer in my area and was told it would be a while.after almost a year I contacted them again and they told me I had to call GM because the current recall was no good anymore. Why would I have to call anyone when I had a recall notice and a recall number .”

   NHTSA complaint #11046429, filed 2017-11, 80,000 miles

   “A vehicle ran a red light in a intersection and was close to crashing into the front passenger side. My pregnant wife was sitting on the passenger seat. Thank god we did not get hit. My pregnant wife could have been seriously injured with out the passenger air bags not working.”

   Engine

   Engine misfire, rough running and oil consumption

   • 25 complaints (7%)
   • median 111,000 mi at 8.2 yrs old (22 state mileage)
   • 1 mention a crash, fire or injury
   • filed 2010–2026

   Complaints describe a flashing check engine light with a random misfire, rough running and heavy oil use, sometimes alongside stability or traction-control warnings. Owners say new plugs and wires did not help, and some point to the cylinder-deactivation feature as the suspected cause; a few report a collapsed lifter and the engine running on only part of its cylinders. Others describe stalling with a reduced-power message or an extended crank, and one report of an engine-compartment fire while parked. Mostly reported between 85,000 and 200,000 miles.

   5 related service bulletins

   What to check: Check the oil level and ask how often oil is added between changes; look for a flashing or stored misfire code and any history of lifter or cylinder-deactivation repairs. Service bulletins describe oil-consumption measurement and intake/fuel-injector cleaning procedures for rough idle and misfire symptoms.

   “Stabilty light came on, loss of power, check engine light, rough shifting into 2 gear. It has been down for 2 years. And not fixed yet, chevy dealership does not know what tpo do. There needs tobe a recall on the flex fuel. We were going down I-20 when all this happened. There was nearly an accident”

   NHTSA complaint #11297438, filed 2020-01, 85,000 miles

   “Vehicle has 120,000 miles on it and has a random misfire, with traction control and stabiltrack warnings and a flashing check engine light. Engine has excessive oil consumption and runs rough. Installed new plugs and wires, no change. After reading up on these engines I found out that the afm / dod feature is a common failure for these engines. Gm should step up and help owners with some of the repair costs. This is going to be expensive.”

   Electronic stability control

   Traction control, stability and ABS warnings

   • 16 complaints (4%)
   • median 120,000 mi at 11.0 yrs old (14 state mileage)
   • filed 2012–2024

   Owners report the stability, traction-control or ABS lights staying on, sometimes with the check engine light and a loss of power or rough shifting. Some describe the steering wheel and engine shaking at highway speed with the speed dropping on its own, and one owner reported a major electrical fault found during diagnosis. Complaints often say the dealer could not identify the cause. Reported between about 120,000 and 280,000 miles.

   Recall 10V240000Recall 08V4410002 related service bulletins

   What to check: Watch for any of these lights staying on after the bulb check at startup, and ask whether wheel-speed sensors or the ABS module have been diagnosed. The electrical recalls on file concern the heated washer fluid system, so check by VIN whether those repairs were done.

   “The contact owns a 2007 Chevrolet Avalanche.

Buying note. Inspect the dashboard for cracks and confirm the passenger air bag recalls were completed by VIN, since those two account for most reports on this model year. Also have a shop check oil consumption, any stored misfire codes and underbody rust before agreeing on a price.
