Investigations List

After a preliminary review of consumer complaints and other information related to alleged defects, NHTSA obtains information from the manufacturer(including data on complaints, crashes, injuries, warranty claims, modifications, and part sales) and determines whether further analysis is warranted.  If warranted, the investigator will conduct a more detailed and complete analysis of the character and scope of the alleged defect.

Summary Description: Blue Bird Draglink Failures


Summary

On March 17, 2023, the Office of Defects Investigation (ODI) opened PE23-004 to investigate instances of drag link separation in model year (MY) 2016-2020 Vision school buses manufactured by Blue Bird Body Company (Blue Bird). Since drag links are serviceable items that can wear out, ODI opened this investigation to understand why two drag links separated at the steering arm end shortly after having passed a routine inspection by multiple qualified entities.Two buses used in the same rural school district, owned and maintained by different bus contractors, had both undergone similar annual and semi-annual inspections prior to the start of the school year.Both failed within a week of each other, approximately a month into the school year. ODI interviewed the bus contractors and surveyed the industry to learn what inspection methods were being used and which ones were best at detecting wear in the components.ODI learned that the failed buses had not been inspected using the most thorough methods. ODI collected the drag links from each of the failed buses. Assisted by the Pennsylvania State Police Motor CarriereBay Enforcement Division and using best practice inspection methods, ODI identified and collected a pre-separation drag link from a neighboring school district. The drag links underwent a teardown inspection at the Vehicle Research and Test Center (VRTC) jointly with Blue Bird and THK-Rhythm Automotive, the drag link manufacturer.In all cases, the visual analysis of each drag link end revealed that the grease at the steering arm end was dirty, discolored, and dry in texture, while the pitman arm end was still clean looking and fluid. ODI reviewed the information request data submitted by Blue Bird.No other separations had been reported.ODI contacted additional fleets to determine whether any other separations had occurred that had not been included in the submitted warranty and claim data.None were found. The grease fitting on the steering arm end is obscured by the steering arm itself.Therefore it is believed that inadequate maintenance resulted in the failures that had not been detected during the less-thorough prior inspections.Blue Bird has agreed to issue a notification to all owners to clearly identify all lubrication points and ensure all owners understand the proper lubrication and inspection methods.Blue Bird will also update their service manuals to convey the industry best practices of having someone turn the steering wheel while someone else inspects the drag links while the wheels are on the ground. Since the drag link failures appear to be caused by maintenance and inspection deficiencies and not due to a design, material or manufacturing issue, this investigation is closed.The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist. The Agency reserves the right to take additional action if warranted by future circumstances.

Summary Description: Momentary Increased Steering Effort


Summary

On March 17, 2023, The Office of Defects Investigation (ODI) opened Preliminary Evaluation (PE23-005) to access the alleged defect of momentary increase in steering effort in model years (MY) 2022 and 2023 HondaeBay Civic vehicles. The complaints report that the momentary increase in steering effort (described as "sticky steering") occurs mostly at highway speeds after driving for a certain amount of time. The reports have been received over the past 2 years with most occurring with low vehicle mileage. The steering gear contains a unit that includes a worm gear and a worm wheel. HondaeBay stated this condition of momentary increase in steering effort occurs due to two factors within this unit. During manufacturing, the worm wheel goes through annealing and component conditioning processes. These processes caused internal stress and strain within the worm wheel. This strain was slowly released over the first few months of the vehicle life. Over time, the released strain caused the deformation of the teeth on the worm wheel, causing the worm gear to catch on the worm wheel. This results in the consumer's momentary increased in steering effort. Also, the manufacturing process did not guarantee consistent grease application and therefore, some vehicles within the scope received too little grease which contributes to the momentary increase in steering effort. Analysis of all relevant data indicates that the subject condition occurs early in the vehicle's life primarily in winter months. Additionally, the subject vehicles need to be driven in a straight line for a period of time, possibly until the vehicle is warmed up, to recreate the condition. The condition does not illuminate a malfunction indicator light (MIL). Some complaints allege HondaeBay dealerships are unable to recreate the condition or state this is a normal vehicle operation. However, HondaeBay released Service Bulletin 23-037 in July of 2023 which accurately describes the condition. To address this issue, HondaeBay directs dealerships to remove the electronic power steering (EPS) gearbox and replace with a new gearbox. Further, HondaeBay stated that the worst case steering effort from all warranty returned parts tested was 2.4 pounds. ODI complaint traffic remains steady. ODI has received 13 crashes to date, 11 of which allege roadway departure due to not being able to overcome the momentary increased steering effort prior to their vehicle leaving the roadway. The remaining 2 incidents claim overcorrection of the steering wheel. PE23-005 has been upgraded to an Engineering Analysis (EA23-003) to further assess the scope, frequency and potential safety related consequences of the momentary increase of steering effort. Further the scope has been expanded to include assessment of the AcuraeBay Integra and HondaeBay CR-V models. To review the ODI reports cited in the Opening Resume ODI Report Identification Number document, go to NHTSA.gov.

Summary Description: Steering wheel detachment


Summary

The Office of Defects Investigation (ODI) is aware of two reports of complete detachment of the steering wheel from the steering column while driving in 2023 Model Year TeslaeBay Model Y vehicles.Both vehicles were delivered to the owners missing the retaining bolt (P/N1036655-00-A) which attaches the steering wheel to the steering column. Both vehicles received an end of line repair requiring removal and re-installation of the steering wheel. A friction fit maintained the connection between the steering wheel and the column splines during operation until separation. Sudden separation occurred when the force exerted on the steering wheel overcame the resistance of the friction fit while the vehicles were in motion. Both known incidents occurred at low vehicle mileage. A PE has been opened to assess the scope, frequency, and manufacturing processes associated with this condition.The ODI report cited above can be viewed at http://www.nhtsa.gov under the ODI identification number 11504846.

Summary Description: Certification


Summary

On June 30, 2022, Zoox, Inc. (Zoox) certified that a passenger vehicle it had produced met all applicable Federal Motor Vehicle Safety Standards (FMVSS).Zoox issued a press release shortly thereafter announcing the certification.Zoox describes the "purpose-built" vehicle as bi-directional, equipped with an automated driving system, and lacking traditional driving controls. On September 6, 2022, NHTSA issued a Special Order directing Zoox to answer certain questions and provide information relating to the company's basis for certifying that the vehicle met all applicable FMVSS.Zoox responded to the Special Order on November 7, 2022.As NHTSA continues to evaluate these responses, the agency has determined that further examination is necessary into the process and technical data on which Zoox relied when certifying the Zoox vehicle and related issues. In particular, NHTSA will consider the extent to which Zoox's certification basis depended upon unilaterally developed test procedures or determinations that certain standards were inapplicable due to the unique configuration of the vehicle.
