2012 Chevrolet Sonic

From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited. The rapid burning can cause the inflator to rupture during deployment, potentially causing serious or even fatal injury to vehicle occupants. See 2016 Blomquist Report at www.nhtsa.gov/sites/nhtsa.gov/files/documents/expert_report-hrblomquist.pdf.Consequently, all frontal inflators using propellant 2004 that do not contain a "desiccant" (a substance that traps and holds moisture) in US vehicles are under recall. These "non-desiccated" inflators either have been or are required to be replaced.In some cases, the remedy part for these recalled inflators was, or will be, an inflator using either propellant 2004 or 2004L that does contain a desiccant. None of these "desiccated" remedy parts (which were installed in older model year vehicles) are currently under recall for a degradation concern. Certain subsets of desiccated PSAN inflators using propellant 2004 for use as original equipment, however, have been recalled for a degradation concern. All Takata inflators produced with propellant 2004L contain desiccant, and none of these desiccated inflators using propellant 2004L are under recall for a degradation concern. There have been no reported field ruptures in any non-recalled desiccated PSAN inflators.It is understood that desiccants fully saturate at some threshold, at which point any additional moisture will not be captured. This means the degradation process observed in non-desiccated inflators using propellant 2004 may also occur in non-recalled desiccated inflators using propellant 2004, assuming additional moisture enters the inflator and high temperature cycling occurs. Based on available information, desiccant saturation can occur within the first five years in the worst environments, and the time required for full saturation is affected by multiple factors. While no present safety risk has been identified, further work is needed to evaluate the future risk of non-recalled desiccated inflators using propellant 2004.Three entities -- Takata (now known as TK Global), the Independent Testing Coalition, and Exponent -- have been studying the long-term behavior of Takata desiccated PSAN inflators using propellant 2004L (as well as 2004) in the presence of moisture and temperature cycling. The research efforts, which include development of predictive modeling techniques and field sample analysis, are ongoing. To date, none of the researchers have identified field evidence showing that propellant 2004L is undergoing a degradation process that leads to aggressive deployment and potential rupture. However, the time in service of such inflators remains short compared to that of the inflators using propellant 2004. Further study is needed to assess the long-term safety of desiccated inflators using propellant 2004L.The Office of Defects Investigation is opening this investigation to examine whether a safety defect related to propellant degradation exists in non-recalled desiccated PSAN frontal inflators manufactured by Takata. This investigation will require extensive information on Takata production processes and surveys of inflators in the field. Lists of recall actions that may have used desiccated PSAN inflators as remedy parts, as well as the makes and models originally manufactured with them, is available with the downloadable version of this document (see nhtsa.gov/recalls?nhtsaId=EA21002 -- note this information is subject to change/revision as the investigation proceeds). This investigation does not supersede EA15-001, which remains open.

General Motors (GM) has initiated a safety recall of 31,520 model year (MY) 2012 Buick Verano and Chevrolet Camaro, Cruze and Sonic vehicles to address a defect condition that could result in the primary or secondary stage air bag not deploying.These vehicles are a small percentage of all MY 2012 vehicles and were built on several specific production dates broadly ranging from December 1, 2011 to August 2, 2012 (see NHTSA recall 14V-300 for more information).Also, see attached additional report for more information.This investigation was opened to evaluate the scope of two uninfluenced safety recalls (NHTSA recalls 12V-522 and 13V-023) of certain MY 2012 Verano, Camaro, Cruze and Sonic vehicles.These recalls involved the same defect issue as the new recall mentioned above.Accordingly, this investigation is closed based on the recall actions GM is undertaking.

The contact owns a 2012 Chevrolet Sonic. The contact stated that on several occasions, while coming to a stop, the vehicle unexpectedly remained in second gear. There were no warning lights illuminated. The contact stated that several attempts were needed for the vehicle to shift into another gear. The dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure and referred the contact to the NHTSA Hotline for additional assistance. The failure mileage was approximately 77,000.

The contact owns a 2012 Chevrolet Sonic. The contact stated that when the vehicle was turned on, the brakes, ABS, traction control, and braking system warning lights were illuminated. The contact stated while driving the vehicle at an undisclosed speed, the brake pedal was depressed; however, the vehicle took longer than normal to slow down. The contact stated that while the brake pedal was depressed, the vehicle jerked abnormally. The vehicle taken to a dealer where it was it diagnosed and determined that the brake booster pump assembly needed to be replaced. The vehicle was not yet repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 159,000.

The contact owns a 2012 Chevrolet Sonic. The contact stated while driving 75 MPH, the vehicle lost power. The check engine OBD reader had lost communication with the transmission. The contact merged to the side of the road. The contact then went to auto parts store and attempted to change the speed sensor; however, the parts store had given the contact the incorrect part. The dealer was contacted and informed the contact that the vehicle was already repaired under NHTSA Campaign Number: 14V315000 (POWER TRAIN). The vehicle had lost throttle and power. The contact then took the vehicle to an independent mechanic who diagnosed the vehicle and linked the failure to NHTSA Campaign Number: 14V315000 (POWER TRAIN). The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 86,000.

I purchased this car 2 years ago and it has caused me absolutely nothing but trouble. We have replaced the fan 4 times (twice due to the resistor thats part of the fan failed), headgasket job, intercooler punctures (once inward, once outward), failed valve cover, intake maniford, turbo seals twice, failing check values, new relays for the fan (twice), another drive belt, and now I go outside and theres a puddle of coolant under my car. I have sunk over $8,000 into this car and it has been the worst financial decision ever. Why do the parts keep failing? Why isnt there a heat gage in the dang car so I know its too hot before the light comes on?

The contact owns a 2012 Chevrolet Sonic. The contact stated that while a friend was driving approximately 35 MPH, the vehicle suddenly veered to the right and struck the curb. Upon inspection, it was discovered that the front passenger’s side suspension had failed. The vehicle was later towed to an independent mechanic who diagnosed that the front driver’s side suspension lower control arm had failed and needed to be replaced, along with the front axle and ball joints. The vehicle was not yet repaired. The manufacturer and local dealer were notified of the failure, but no assistance was provided. The failure mileage was 111,000.
