While driving on highway, stopped at a light, I went to accelerate and truck lurched forward, made a loud bang and would not engage. The engine whines when accelerator is pressed, but no movement. Also, vehicle would roll back without the emergency brake on. There were zero warnings prior to complete failure of truck. Contacted gm and chevy, and was offered no help, until out of pocket diagnostics are completed at a gm/chevy dealer (and at this point since vehicle is out of warranty, owner was told that help from gm is not guaranteed). Truck is at a private shop, preliminary findings are that the front differential is damaged. The power output shaft and spline is stripped, the cause is vehicle (drivetrain) design does not allow engine oil to get to these components. The parts become dry and brittle, which is why the gears are stripped and failure occurred. This is not an owner maintenance issue, but a complete design flaw. These components should be encased and be getting lubricated from the engine oil. Further findings will be reported.

Leaving my place of employment, I made a left turn on to the road. While in the turn, my SUV began to stall.the engine malfunction indicator lamp came on. I managed to coast on to someone's property. I turned the engine off and sat there for approximately 15 minutes. Then, I restarted the engine and managed to get home. I used a scanner to get the code for the possible malfunction. The malfunction was listed as p2135, which read, in part "throttle/pedal position sensor/switch a/b voltage correlation". This same problem was cited in the federal safety agency: action number: 10047220 service bulletin number: 340852., for the model year 2008. However, the dealership and gm, have stated that my vehicle is not covered. This is a great source of frustration. With the hundred of thousand of vehicles that has been recalled by gm for a multitude of defects, somehow the model year 2008, is a model of perfection. Fortunate for me, that I was not on the freeway when my vehicle began to loose power.

Repeated issue. Smell of smoke/burning triggers dash warning signals. Same dash warning signals come on without smell of smoke/burning. Cycle repeats itself without pattern, and includes during 4 wheel use. Vehicle taken to multiple chevrolet dealerships for service (utah, north carolina and washington) with the dash warning lights on. Utah and nc claim unable to replicate event or identify problem, so listed as unknown without correction. Gmc executive office interdiction resulted in replacement of stereo even though dash light indicate powertrain & electrical. Stereo broke 2 mos later. Gmeo and wa identified fuse issue related to 4 wheel drive, but unable to replicate smoke/burning before claiming issue resolved. Dash warning lights constantly come on and off indicating problem with powertrain/electrical. Gmeo closed case as resolved.

I bought this vehicle back in september 2009. Ever since I bought the vehicle I have had problems with the traction control lights coming on for no apparent reason. This happens when its hot and cold, dry or wet. Just starting the engine makes then come on. I have been back to the dealer for 2 years now for the same problem and they tell me that they don't know why it is happening and can't fix it. My vehicle is now out of warranty and will never be fixed. ?

Tl*the contact owns a 2008 chevrolet trailblazer 4wd. While driving approximately 30 MPH during inclement weather, the stabilitrak service light came on the dashboard. She stated that the stabilitrak does not work while driving over an ice patch. The vehicle was taken to the dealer for the failure who reset the light. The vehicle was taken to the dealer at least seven times for the failure; however, the failure continued to occur. The vehicle was not repaired for the failure. While driving 70 MPH, the vehicle would shift from two wheel to four wheel drive low. The vehicle was taken to the dealer and they reset the light. Over a two year period, the vehicle was taken back and forth to the dealer and eventually the dealer replaced the transfer case. The vehicle was repaired. The approximate failure mileage was 15,000 and the current mileage was 70,000.

Rented 2009 chevrolet trailblazer SUV from national car rental on 8/31/08 with 436 miles on odometer. Drove approx 800 miles over a period of 7 days. On 9/6/08, while driving on I-75 southbound at 70mph, vehicle shifted itself into 3rd gear, would not go into 4th or overdrive. Rpm's at 70 MPH were approx 3,500. Pulled off road at interstate exit, transmission made a "clunk", jolting me and my wife rather intensely. Topped off the fuel, quite gingerly began our trip again. As vehicle reached 45-50mph, it downshifted itself into 3rd gear, jumping the RPM's and causing the vehicle to lurch harshly. Called national, requested they "talk us in" to saginaw, mi office for vehicle exchange. National rep told me she "could not read a map" and "can't tell what exit you should take to get here". We once again pulled off the road at an exit, slowed to a stop, put vehicle in park while attempting to locate a national office. While on "hold" with national's roadside assistance dept., decided to try to get on the road again. Reached 40mph on I-75, when transmission completely failed. Motor revved when throttle depressed, but no forward motion occurred. Pulled off in emergency lane (narrow, next to a steep ditch), and were stuck there for nearly two hours while national performed a "tow-exchange". Eventually, another vehicle was brought out, but not until after we were stuck with huge semi tractors running 80mph past us for two hours, and having no means of shelter from the potential of becoming "roadkill"!! Failure of transmission was unprecedented. Vehicle drove normally until it would not shift into 4th / overdrive. Failure was progressive and severe thereafter.
