2013 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.

The contact owned a 2013 Chevrolet Sonic. The contact stated that the vehicle had previously sustained undercarriage damage while driving at 20 MPH and hitting a pothole. The undercarriage was repaired. Additionally, the contact stated that while driving at 25 MPH, the vehicle started to overheat. A coolant temperature warning light was illuminated. The contact pulled into the Walmart parking lot and parked the vehicle. An independent mechanic was notified of the failure. The contact stated that while the mechanic was towing the vehicle to the repair shop, the vehicle caught on fire. The mechanic pulled over to the side of the road. The incident occurred near the mechanic's shop. The contact stated that the workers of a nearby recreation center extinguished the fire with fire extinguishers. There was no injury sustained. The vehicle was towed to an unknown location and was deemed a total loss by the insurance company. The contact stated that the fire originated from the engine compartment. A police report was filed. The dealer and the manufacturer were not notified of the failure. The failure mileage was approximately 134,000.

Vehicle enters into catalyst monitor too early. Monitor Fales indicating that the catalyst is below efficiency threshold. A vehicle is run for a significant amount of time before being allowed to enter the driving conditions for the catalyst monitor, monitor will pass. This indicates that there is a programming failure, not an actual component failure. Theory has been tested multiple times. Catalyst had also been tested by temperature sensor as well as by taking readings with a gas analyzer before and after the catalyst. Everything indicates the catalyst is well within operating parameters. Theories, test, and confirmations have been conducted by a certified technician and mechanical engineer.

On 7-27-2023 General Motors issued a recall on 2013 models of Sonic, my VIN was not included in this recall. However on 4-16-2025 my sonic was involved in a impact incident in which the air bags should have deployed, and did not. It is my opinion that Chevy, knowing of the issues with the model of car, should have issued a recall for my vehicle as well, but did not. As a result I suffered additional strain and injury during my impact as no airbags deployed.

The contact owns a 2013 Chevrolet Sonic. The contact stated that upon turning off the vehicle, the ignition key remained stuck in the ignition switch. Additionally, the contact noticed that the gear shift indicator was indicating that the transmission was in park(P) and in drive(D) simultaneously. The contact stated that upon moving the gear shifter in and out of park(P) several times, and shifting back to park(P), the contact was able to release the key. The contact stated that the failure had recurred several times. The vehicle was taken to the dealer, where the gear shifter was replaced. The vehicle was repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 126,419.

UNKNOWN. Our car caught fire but I'm not sure what actually caused it, it was in perfect working condition before. I saw articles online saying there was a voluntary recall due to faulty welding in the fuel tank so it could be that. I believe it's a dangerous defect and should be an official recall. My family and I almost lost our lives because of it
