GM Suspension Bolts Could Fracture

Posted on by

When it comes to vehicle safety, every component plays a crucial role in ensuring a smooth and secure ride. Recently, General Motors (GM) discovered a potential issue with improperly heat-treated suspension bolts in select Cadillac, Chevrolet, and GMC vehicles. This problem, if left unaddressed, could lead to serious safety concerns, including misaligned rear wheels and an increased risk of accidents.

In August 2023, a plant quality manager at GM’s Arlington, TX assembly plant uncovered a concerning issue. They identified that as many as 223 vehicles may have received improperly heat-treated bolts during the manufacturing process. Unfortunately, these vehicles were not contained at the plant, which raised alarm bells. Of the affected vehicles, 189 were located in the United States.

In response to this discovery, GM initiated a comprehensive investigation into the issue. Extensive testing and analysis were conducted to determine the potential consequences of these improperly heat-treated bolts. What they found was alarming: in the event of a control arm separation, there was a distinct possibility of rear wheel misalignment that could adversely affect the vehicle’s handling.

It is worth noting that, up to this point, GM had not received any reports of field incidents related to this condition. Recognizing the potential risks associated with the improperly heat-treated suspension bolts, GM’s Safety Field Action Decision Authority (SFADA) made a decision in September to conduct a safety recall to address the issue.

The vehicles affected by this recall include the following 2023 models:

  • Cadillac Escalade
  • Cadillac Escalade ESV
  • Chevrolet Suburban
  • Chevrolet Tahoe
  • GMC Yukon
  • GMC Yukon XL

If you own one of the aforementioned vehicles and receive a recall notice, it is crucial to act promptly. GM will ask you to return to your authorized dealer to have both rear suspension outer control arm bolts replaced. This proactive step is vital to ensure your safety and the proper functioning of your vehicle. To facilitate this process, GM has assigned a unique recall number for this issue, N232415910, and the National Highway Traffic Safety Administration (NHTSA) has assigned the campaign number 23V-642.

2021 Subaru Impreza Suspension Problem Could Lead To Loss Of Vehicle Control

Posted on by

Subaru of America have decided that a defect could exist in the suspension of certain 2021 Subaru Impreza vehicles. Owners are advised to NOT drive their vehicle until the repair can be completed.

In June 2021 Subaru opened an investigation into the 2021 Impreza, after receiving a field report of a partially separated lower control arm. In August a second field report was issued with a similar condition as the previous report. The vehicle production dates were two (2) days apart and the LOT number stamped on the control arm were the same. As a result of the joint investigation with the supplier, 75 left front lower control arms containing a specific LOT number were identified as potentially containing an improper weld. An improper weld in this location could lead to a partial separation of the lower control arm from the cross member. If this partial separation occurs, the tire could contact the wheel well structure and the driver could lose control of the vehicle.

Description of the Cause: Equipment on the control arm assembly line was damaged, resulting in contact between the part ejector rod and the welding torch. This interference caused the welding torch to be unable to trace the proper welding path and resulted in an incomplete weld at the joint.

For all of the potentially affected vehicles, Subaru dealers will inspect the LOT number stamped on the left front lower control arm. If the control arm contains a specific LOT number, the part will be replaced. Until the inspection/remedy is completed, customers will be instructed not to drive their vehicle and to make arrangements with their Subaru dealer to have the vehicle inspected. Subaru’s number for this recall is WRI-21 and the NHTSA campaign number is 21V-675.

Nissan will be asking the owners of certain 2020 Nissan Murano SUVs, to return to their dealerships for a problem that could result in loss of vehicle control. Approximately 15,000 vehicles are affected by this recall.

According to the defect report, an equipment failure at the supplier resulted in improperly formed billets in the transverse links. As a result, the right and left transverse links are out of specification and in rare cases could separate from the ball joint. This could result in loss of vehicle control and an increased chance of an accident.

Owners of affected vehicles will be notified to return to their dealer to have the left and right hand transverse links inspected for the affected LOT codes. If the LOT code is identified, the dealer will replace the links and perform an alignment.

Nissan’s number for this recall is PC797 and the NHTSA campaign number is 21V-170.

Posted on by

Toyota will be contacting the owners of certain 2019-2020 Rav4 and Rav4 Hybrid vehicles because of a problem that could exists with the front lower suspension.

According to the defect report, the lower suspension arms connecting the front wheels to the vehicle front cross member may be defective due to improper production conditions at the steel supplier. If a vehicle with an affected suspension arm is repeatedly driven with rapid acceleration and deceleration, it is possible that cracks could propagate throughout the arm, causing it to eventually separate from the front wheel assembly. The problem could result in loss of vehicle control and an increased risk of a crash.

Owners receiving notices will be asked to return to their dealers to have both front lower suspension arms replaced. Toyota’s interim numbers for this recall are 20TB08 / 20TA08 and the NHTSA campaign number is 20V-286.
