Takata recall and another issue of power loss----- I have taken my truch to the dealership to have the takata air bags replaces and they told me that they do not have the parts to replace them. Power loss: I can be driving and the vehicle goes into a drastic and immediate power reduction. I have nearly bee rear-ended several times and the vehicle jerks suddenly throwing everything forward as though it is nearly a sudden stop. It will not drive over 20 mph when this happens. It will not reset until I pull over, remove, and reassemble, the battery cables. This happens during, and following, every rainy day. It also happens for no specified reason. It happened 3 times in the last 24 hours--no rain at all.

The engine in the Chevy vehicles from 2007-2015 all have high oil consumption and require engine replacement anywhere after 500 miles. My car was purchased new and needs a new engine a little over 5 years later?

- Avondale, LA, USA

The engine in this vehicle burns/vaporizes oil at a rapid pace. I have a 2011, 114K miles, and had to replace the pistons to the tune of $5400 - Chevrolet would not help with costs. 6 yr old vehicle, just over 100K miles and have to replace the pistons.. I had kept up all scheduled maintenance at the dealership. Have a "warranty forever", life time power train warranty, and denied my claim because it was due to 'wear and tear'. how can my 6 yr old, 114K mile vehicles essentially need a new engine? Chevrolet should be disgusted with themselves. I know many others with similar year, same engine and have the same problems. This problem should be investigated. I have not faith in the Chevrolet product anymore.

The contact owns a 2011 Chevrolet Silverado 1500. While driving approximately 40 mph, the engine began to emit a knocking noise and the engine traction warning indicator illuminated. Also, the vehicle took a longer amount of time than usual to stop when the brake pedal was depressed. The contact took the vehicle to a certified mechanic who diagnosed that the number one and number 7 spark plugs were burned out and needed to be replaced. The vehicle was repaired, but the failure recently recurred. The manufacturer was made aware of the failure and opened a case (reference number: 8/2905223479). The approximate failure mileage was 62,765.

Vehicle went into limp mode while cruising at 65 mph. Traction control disabled light and check engine light illuminated. Message center displayed "service stabilitrak" "service traction control" and "engine power reduced" messages. Vehicle slowed and transmission downshifted. Vehicle failed to accelerate while depressing the accelerator pedal. With accelerator to the floor the vehicle would not exceed 35 mph in a flat grade. On a steep incline the vehicle would not exceed 15mph with the accelerator pedal to the floor. The issue has occured several times before. Parking the vehicle on the side of the road and several ignition cycles have in the past have resolved the issue. This is a known issue with GM vehicles using a drive by wire throttle body and it has been recalled on other model years.

Engine power reduced, service traction control, service stabilitrak, these warning lights came on and as my truck slowed down no matter how much gas I gave it. Also the check engine light came on. I shut truck off and waited a couple minutes then started truck up. It ran for a few minutes then the same 3 warning lights came on along with the check engine. Light. Is there a recall or a technical service bulletin (tsb) for this issue. I did read that there might be a tsb campaign # [xxx] for this issue. Is there any paperwork that can be emailed to me to give to the GM dealer to help me with this issue. The vehicle was in motion the first time it happened. It also happens while parked in driveway and just warming up truck. Thank you, [xxx] information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

The fuse relay block on my 2011 Chevrolet Silverado 1500 with only 56,000 miles nearly caught fire when the rear window defroster and heated mirrors would not turn off even with the key removed. The problem was traced to a bad ground on circuit G200, this is part of the switch circuit that controls the mirrors and defroster. GM has designed a circuit that has the ability to turn itself on even when the car is off and the key removed! but even worse GM refuses to pay for the parts or labor to repair my truck. I have made several calls to GM customer service and while initially encouraging GM has refused to stand behind their product. Howard the customer service representative at GM couldn't disclose to me the amount of financial help they offered the dealership, it turns out they didn't offer any help at all. I'm not sure I will buy another GM product after this experience.

My dash is cracking around the passenger airbag and above the instrument cluster. I am concerned that the cracked areas could come loose and become a projectile. The engine is also burning oil badly and could shut down while driving

First of three vehicle collisions this year involving Chevrolet Silverado that have caught fire after involved in frontal impacts. Vehicle traveling westbound on sr 58 in lane county, Oregon. Involved in secondary collision with a Toyota pickup truck that had been struck by a loose truck tractor wheel. The impact by the wheel caused the Toyota to encroach into the path of the Chevrolet. The occupants of Chevrolet were able to extricate themselves. The vehicle subsequently caught fire and suffered extensive fire damage.

We were making a stop at the light, when a 18-wheeler didn't stop and hit us in the back, pushing us towards the bus that was in front of us, making the glass of the back break and throwing all the crystals in our body and clothes, the air bags never open, the front seats were broken and 3 of the 4 doors couldn't close anymore, the driver tried to make a move to the left or right, but he could not, because we were stuck, when we realize there were no major injury, we stayed until the red cross came to check our condition, but there were crystals everywhere so we couldn't move without hurting ourselves. We buy the truck with 2 miles, we are the only owners.

The automatic belt tensioner pulley is in the process of going out. The pulley itself is slowly suffering from a high pitched whining noise which is caused by bearing failure. With the current mileage the part in question shouldn't by any means be failing, the tensioner works fine but the pulley wobbles a bit too much. If the pulley continues to wobble more and finally results in catastrophic failure it can shred the serpentine belt which will render the vehicle useless or even become a danger to any and all occupants in the vehicle especially if it fails on the highway. If the belt goes out it can bend other pulleys or shear off pulleys, bolts, or even bend the harmonic balancer (engine vibration dampener) which would result in a blown or seized up engine. I'll also add that the belt could cause a fire if it gets wedge between other spinning pulleys at the time of the pulley's bearings overheating and the pulley either breaking off or causing the belt to shred.

At 36000 miles the engine burns oil. So far as of 46000 miles pistons burned have been replaced pvc filter and valve were replaced along with valve cover. At present 54000 miles engine still burns oil.

- Denton, TX, USA

Check engine light is displayed and the motor is hesitating. This issue is a second occurrence due to the valve cover leaking and causing the spark plugs to go bad. First time the vehicle was under warranty at approximately 29000 miles and now the vehicle has 39000 miles and the issue has recurred. This appears to be a continually recurring problem for 2011 Chevrolet Silverado trucks.
