Front seatbelt retractors may not lock as intended during a crash because of defective parts from supplier ZF. The safety defect applies to multiple makes and models. As a result, FCA US has announced a safety recall on 2019 and 2020 Model Year (DT) Ram 1500 Pickup, 2019 Model Year (DJ) Ram 2500 Pickup, 2019 Model Year (JL) Jeep Wrangler, and 2020 Model Year (JT) Jeep Gladiator vehicles. FCA US is not aware of any accidents or injuries. General Motors recalling some 2020 Chevrolet Corvette models as well. GM is not aware of any injuries or accidents either.
The safety defect appeared at GM during barrier testing of a 2023 model year Corvette. GM worked with ZF to analyze the root cause of the retractor failure, including teardowns, computer analysis, and CAE simulations. That analysis showed that the retractor failure was caused by the locking mechanism not being properly engaged. The same part is used on current production models. Continue reading









CARB Warns Vehicle, Engine Makers on Emissions Cheating
CARB’s recent screening tests and investigations have uncovered several systemic violations. In general, CARB has found that manufacturers have failed to submit required information about their engines and vehicles during the certification process and following certification in-use. Manufacturers are required to submit complete and accurate information according to California Code of Regulations (CCR) sections and test procedures incorporated in the CCR sections for mobile source categories.
The California Air Resources Board (CARB) today sent a letter to automakers and other vehicle and engine manufacturers “encouraging them to disclose” by the end of the year 2020 any unapproved hardware or software programs that impact emissions control systems in vehicles sold in California, aka auxiliary emission control devices or AECDs.
The move comes as CARB nears completion of a new testing lab that gives the agency greater ability to detect these unapproved programs. Given the sorry history of so-called cycle cheating on CARB and EPA compliance tests, it’s not surprising that CARB is increasing efforts to protect public health and reduce combustion pollution. CARB is also immune from the federal machinations of the Trump Administration to roll back, cancel or ignore the negative effects of air pollution on people, communities and the planet itself.
