Potentially Missing Spot-Welds

Frequently Asked Questions

Original Publication Date: April 13, 2022

 

Q1:What is the condition?

A1: The front shock absorbers in the affected vehicles are mounted to body panels that may be missing some spot-welds. Incorrect welding could eventually cause a shock absorber to separate from the mounting area, resulting in a loss of driving stability and increasing the risk of a crash.

 

Q1a: If the condition exists, are there any symptoms/warnings that drivers might experience?

A1a: Initially, a driver may not experience any symptoms/warnings if the vehicle does not have the proper spot welding.  Over time, cracks and breakage may occur on other spot-welds and/or on the body panels around the front shock absorber mounting areas, leading to abnormal steering feeling. Under longer-term (time and mileage) use, this could eventually cause a front shock absorber to separate from the mounting area, creating an abnormal noise, and resulting in a loss of vehicle driving stability.

 

Q2: What is Lexus going to do?

A2: For all involved vehicles, Lexus dealers will inspect the welding near the shock absorber mounting area. For vehicles with missing spot welds, additional welds will be added to the body panel(s) FREE OF CHARGE. If the inspection determines that any welds on the right or left body panel have failed, the body panel with the failed weld(s) will be replaced with a new body panel FREE OF CHARGE.

 

Q3: Which and how many vehicles are covered by this Safety Recall?

A3: There are approximately 4,300 vehicles covered by this Safety Recall. Approximately 70 vehicles involved in this Safety Recall were distributed to Puerto Rico.

Description of Problem:

The subject vehicles are manufactured with body panels that are spot-welded to the left and right front shock absorber mounting areas.  During the spot-welding of these panels, there is a possibility that certain spot-welds were missed.  In this condition, cracks and breakage may occur on other spot-welds and/or on the body panels around the front shock absorber mounting areas.  Under longer-term (time and mileage) use, this could eventually cause a front shock absorber to separate from the mounting area, resulting in a loss of vehicle driving stability, increasing the risk of a crash.

 

Chronology of Principal Events:

January 2022 โ€“March 2022

In late January 2022, during a sampling inspection of a vehicle body at the NX vehicle assembly plant, ToyotaeBay logo found that some spot-welds on the body panels around the left front shock absorber mounting area were missing.  ToyotaeBay logo began to investigate the welding machine and its process.

While reviewing the welding process settings, ToyotaeBay logo found there was a possibility that the welding machine for the left and right side of a vehicle body may not have recognized a work completion clear signal which should have been received from the process control board after the welding work was completed.  If this occurs, the welding machines would remain in a โ€œwork completedโ€ status and would not execute the next welding operation.  ToyotaeBay logo updated the logic of the process control board to allow the welding machines to recognize the signal properly.  In parallel, ToyotaeBay logo began an investigation to determine if other vehicle bodies may have the same condition.  It was found that a small number of vehicle bodies at the plant had missing spot-welds at either the left or right front shock absorber mounting area.

ToyotaeBay logo conducted duplication testing on each of the welding machine to assess why the machines may not have recognized the signal from the process control board.  The left and right machines failed to recognize the signal in 5 out of 9,242 tests.  In addition, it was confirmed that, due to a variation in the signal (pulse signal) width, the pulse signal could be shorter than the recognition interval in the welding machine, causing the machine to occasionally not recognize the signal.  This further confirmed the possibility that missing spotwelds had sporadically occurred.

In February 2022, ToyotaeBay logo began an investigation of the potential effects that missing spot-welds might have on vehicle performance.  A CAE analysis was performed to simulate frontal collisions with missing spot-welds to evaluate the effects, if any, on vehicle crashworthiness.  It was found that the load and deformation at the front of the vehicle cabin was smaller than in a properly welded vehicle; therefore, the missing spot-welds did not negatively affect the vehicleโ€™s crash performance.

Additionally, ToyotaeBay logo considered the effect of the missing welds on the vehicle driving stability.  This was evaluated using further CAE analysis and full-vehicle drive testing.  The drive testing was conducted using a new vehicle with missing spot-welds; it was found that there were no effects on vehicle driving stability.  However, based on the CAE analysis, ToyotaeBay logo assessed that, over time, cracks and breakage could occur on other spot-welds and/or on the body panels around the front shock absorber mounting areas.  ToyotaeBay logo believed, under longer-term use (time and mileage), this could eventually cause the front shock absorber mounting panel to separate from the mounting area, which could result in a loss of vehicle driving stability and increase the risk of a crash.

 

April 7, 2022

Based on the results of the above investigation, ToyotaeBay logo decided to conduct a voluntary safety recall campaign.

As of April 6, 2022, based on a diligent review of records, ToyotaeBay logoโ€™s best engineering judgement is that there are 0 ToyotaeBay logo Field Technical Reports and 0 warranty claims that have been received from U.S. sources that relate or may relate to this condition and which were considered in the decision to submit this report.

 

Description of Corrective Repair Action:

All known owners of the subject vehicles will be notified to return their vehicles to a Lexus dealer.  For all involved vehicles, the dealers will inspect for the presence of spot-welds around the front shock absorber mounting areas.  For any vehicles where missing spot-welds are found, ToyotaeBay logo is developing the remedy for this condition and will notify the agency when the remedy is developed as required under 49 CFR Part 573.
