• Hyundai and Kia agree to settle airbag defect lawsuit; each original plaintiff gets $2,500, while attorneys get over $20 million.

• Settlement covers more than a dozen Hyundai and Kia models going back to 2010, impacting millions of current and former owners.

• Fairness hearing set for September 29; consumers may file reimbursement or residual payment claims by March 2027.

Hyundai and Kia have reached a proposed settlement in a sweeping class-action lawsuit over defective airbag control units and, in a now-familiar twist, most of the money is headed not to consumers but to attorneys. The agreement awards $2,500 each to 20 original plaintiffs, while lawyers representing affected customers will receive over $20.4 million.

The case stems from alleged defects in airbag control units supplied by ZF-TRW, which could fail during a crash due to electrical overstress. The lawsuit consolidates over 20 class-action suits dating back to August 2019, following a recall of more than 1 million Hyundai and Kia vehicles. Other automakers named in the suit, including Toyota and Mitsubishi, have previously settled similar claims.

The vehicles initially affected included 20112013 Hyundai Sonata and Sonata Hybrid models, as well as 20102013 Kia Forte, Forte Koup, Optima, Optima Hybrid, and Sedona. But the settlement agreement now includes a broader list of models, encompassing millions of vehicles manufactured between 2010 and 2023:

Eligible Vehicles:

• 20112019 Hyundai Sonata

• 20112019 Hyundai Sonata Hybrid

• 20182023 Hyundai Kona

• 20222023 Hyundai Kona N

• 20192021 Hyundai Veloster

• 20102013 Kia Forte and Forte Koup

• 20112020 Kia Optima

• 20112016 Kia Optima Hybrid

• 20112012, 2014 Kia Sedona

While Hyundai and Kia have agreed to the settlement, they admit no wrongdoing. The deal provides several forms of compensation, including:

• A 10-year warranty on new airbag control units installed under the recall (limited to failure from electrical overstress).

• Reimbursement for reasonable out-of-pocket repair costs tied to recalled vehicles.

• Residual payments of up to $350 for owners of recalled vehicles and $150 for unrecalled ones.

Consumers who believe they are eligible may visit acusettlement.com for information and to submit a claim form. However, the settlement is not yet final it requires court approval following a fairness hearing scheduled for September 29, 2025. If approved, claim forms must be submitted by March 29, 2027.

Chemical exposure may have more risks than many consumers anticipated

• Blood levels of PFAS (forever chemicals) were linked to about a 31% increased future risk of type 2 diabetes.
  

• The study compared 180 newly diagnosed diabetes cases with 180 matched nondiabetic controls from Mount Sinais BioMe cohort.
  

• Metabolic disruptions in amino-acid and drug-processing pathways may offer clues to how PFAS interfere with blood sugar regulation.
  

Per and polyfluoroalkyl substances (PFAS), or forever chemicals, have gotten a lot of attention recently for the plethora of health risks associated with them.

Now, a new study from Mount Sinai suggests that PFAS exposure may quietly raise your risk of developing type2 diabetes.

PFAS are synthetic chemicals that resist heat, oil, water, and stains, and are found in countless everyday consumer products, researcher Vishal Midya, Ph.D., M.Stat., said in a news release.

Because they dont break down easily, PFAS accumulate in the environment and in human bodies. Our study is one of the first to examine how these chemicals may disrupt the bodys metabolism in ways that increase diabetes risk particularly in diverse U.S. populations.

The study

The research team conducted the study using BioMe, a healthrecord linked biobank that has enrolled over 70,000 people at Mount Sinai Hospital since 2007.

They selected 180 individuals recently diagnosed with type 2 diabetes and matched them with 180 similar participants (same age, sex, ancestry) who did not have diabetes.

Blood samples from all participants were tested for PFAS levels. The researchers then examined how increasing PFAS exposure related to subsequent diabetes risk, while also exploring metabolic signatures in pathways tied to aminoacid biosynthesis and drug metabolism.

The results

The key finding: For each step up in PFAS exposure (e.g. from low to moderate, moderate to high), there was a 31% higher risk of developing type 2 diabetes later on.

While the study cant prove PFAS causes diabetes directly, it did find signs that PFAS may disrupt critical metabolic processes specifically aminoacid biosynthesis and drug metabolism which are intimately involved in regulating blood sugar.

This research leverages an exposomics framework to characterize environmental impacts and associated metabolic alterations contributing to the development of type 2 diabetes in vulnerable U.S. populations, researcher Damaskini Valvi, M.D., Ph.D., MPH, said in the news release.

These findings can help us design more effective interventions for the early prevention of type 2 diabetes in the future, taking into account individuals exposures to environmental chemicals along with other well-known genetic, clinical, and lifestyle factors implicated in diabetes development. Mounting research suggests that PFAS are a risk factor for several chronic diseases, such as obesity, liver disease, and diabetes.

Study finds surprising microbial benefits to swapping out your usual nighttime snack

• Replacing a bedtime carb snack with pistachios significantly altered gut bacteria in adults with prediabetes.
  

• Beneficial microbes linked to anti-inflammatory effects and gut health increased after pistachio snacking.
  

• Harmful bacteria tied to heart and kidney risks were reduced during the pistachio phase of the study.
  

If youve ever reached for toast or a few cookies before bed, youre not alone.

However, researchers at Penn State recently asked a fun question: what if you replaced that carb-heavy snack with pistachios instead?

For adults with prediabetes, they wondered whether a nighttime pistachio habit could nudge the gut microbiome in a healthier direction.

Pistachios seem to be able to meaningfully shift the gut microbial landscape in adults with prediabetes especially when consumed as a nighttime snack, researcher Kristina Petersen said in a news release.

These microbiome changes may offer other long-term health benefitspotentially helping to slow the development of Type 2 diabetes or to reduce systemic inflammationwhich we hope to explore in future research.

The study

The study involved 51 adults diagnosed with prediabetes. For 12 weeks, the participants were assigned to one of two different test groups: one group was instructed to eat two ounces (57 grams) of unsalted pistachios each night, and the other group was instructed to eat 15-30 grams of carbs.

A common dietary recommendation for individuals with prediabetes is to consume a nighttime snack consisting of 15 to 30 grams of carbohydrates to help regulate overnight and morning blood glucose levels, researcher Terrence Riley said in the news release.

As an example, you could eat one or two slices of whole grain bread.

At the beginning and end of the 12week period, stool samples were collected and analyzed using 16S rRNA gene sequencing. Thats a lab method that lets scientists identify and compare which bacterial species are present in the gut.

The results

At the end of the pistachio phase, participants showed clear differences in their stool bacterial communities compared to when they followed the carbohydrate snack routine. Statistical tests confirmed that the overall bacterial diversity was significantly different between the two conditions.

Specifically, levels of bacteria like Roseburia and members of the Lachnospiraceae family increased. These are known to produce butyrate, a shortchain fatty acid that fuels colon cells, helps maintain the gut lining, and supports antiinflammatory pathways.

At the same time, the pistachios led to decreases in some bacterial taxa linked to less favorable outcomes. For example, Blautia hydrogenotrophica which produces compounds associated with adverse effects on heart and kidney health and Eubacterium flavonifractor which can break down antioxidant compounds were both lower after pistachios.

Bottom Line

While this doesnt mean pistachios are a miracle cure for prediabetes, the findings suggest that switching from a simple-carb bedtime snack to pistachios could meaningfully reshape the gut microbiome in a way that may support metabolic and gut health.
