Mercedes-Benz faces recall over window trim

Laguna Hills, CA – Nov. 4, 2019 – Mercedes-Benz USA recently had to issue a recall for a number of light sport utility vehicles in its 2020 model year for issues related to mounted rear window trim bars that were installed outside of company specifications.

Altogether, nearly 13,800 vehicles were involved in the recall, all of which are believed to carry this defect. This includes the following light SUVs, all in the 2020 line:

  • 10,068 GLE350 4MATICs
  • 2,290 GLE450 4MATICs
  • 1,148 GLS450 4MATICs
  • 22 GLS580 4MATICs
  • 1 GLE350

It is believed 100% of the specific vehicles in the recall carry the defect in question. Those light SUVs were identified via production records, and many have non-sequential vehicle identification numbers. However, many other vehicles sharing the same model year but which outside the recall group have trim bars that were installed properly.

The Defect

Specifically, all those vehicles – each one a GLE-Class or GLS-Class light SUVs produced between Aug. 23, 2018, and Sept. 27, 2019 – have a trim bar fastening on the rear door windows that could, under certain driving conditions, separate from the vehicle entirely. While this would not pose a likely risk to the drivers of these vehicles themselves, others around them on the road could be injured or become more likely to crash as a result of such a detachment.

The issue arises due to a tolerance deviation at the supplier, and unfortunately drivers of these vehicles will not be able to detect whether their fastenings are at risk for failure.

Timeline of Events

Around mid-August of this year, Daimler Auto Group – which controls Mercedes-Benz USA – received a report of a situation in which one such rear door window fastening failure occurred on a GLE-Class light SUV. The company then began an investigation into the issue, to better understand how it began and what could happen in the event of a failure. Over the course of about six weeks, the investigation determined that the issue came at the supplier level, and it would need to be addressed in short order.

On Sept. 27, the company determined that it could not rule out this issue becoming a safety problem for the other affected vehicles, and ordered the voluntary recall at that time.

The Solution

Drivers who receive the recall notice should return to an authorized Mercedes-Benz dealer. There, technicians will check the fastening on the rear door windows and, if necessary, rework them so that they once again fall within specification at no cost.

However, the company does not plan to provide any notice about pre-notice reimbursements for owners of these vehicles, as all the affected models are within warranty, given that they are in the 2020 model year. The company also noted that as of Sept. 27, the design tolerances of the parts DAG receives from the Kentucky-based supplier has changed, so no further issues of this type will occur.

Mercedes-Benz dealers were first notified of the voluntary recall on Oct. 11, and owners of these vehicles will receive their own notifications around the first week of December.

Chrysler Announces Recall on Certain Ram 1500 Trucks

Laguna Hills, CA – October 31, 2019 – The recall of certain 2014 – 2019 Ram 1500 trucks, including some 1500 Classic Pickup vehicles, was announced by Chrysler earlier this month.

All trucks involved with the recall are equipped with 3.0L Eco Diesel engines that have been outfitted with a faulty exhaust gas recirculation (EGR) cooler.

The defect

The safety recall report filed with the National Highway Traffic Safety Administration explains that the issue involves the EGR coolers on vehicles listed for the recall. The defect leaves the coolers susceptible to thermal fatigue.

“Thermal fatigue may cause the cooler to crack internally over time,” stated Chrysler’s own description of the defect within the safety recall report.

“An EGR cooler with an internal crack will introduce pre-heated, vaporized coolant to the EGR system while the engine is running … potentially resulting in combustion within the intake manifold, which may lead to a vehicle fire.” 

More than 100,000 vehicles are involved in the recall, all of which are expected to contain the defect. Chrysler utilized engine assembly plant records and other information to determine which vehicles were built with the “suspect” EGR coolers.

Timeline of events

The first signs of the defect came in May 2019, when an investigation was opened into engine compartment fires in Ram 1500 3.0L Eco Diesel trucks, according to the chronology report provided by Chrysler.

An inquiry running through October revealed numerous instances of warranty reports and associated repair orders that were related to the defect.

Meetings with diesel engineers and vehicles inspected from other countries allowed the manufacturer to “better understand the fire dynamics involved, and to rule out climate as a potential exacerbating factor.”

The decision to conduct a vehicle recall was made on October 17, after Chrysler had identified more than 60 field reports potentially related to EGR cooler failure.

The solution

According to paperwork Chrysler has filed with the NHTSA, the recall itself is expected to begin sometime in December 2019, although the remedy itself remains under development at the current time.

GM Recalls Numerous Vehicles Due to Electronic Stability Control Malfunction

December 16, 2021 Update – General Motors (NYSE:GM) has remedied issues with 524,144 models dealing with a software error that can cause unintended braking. Additionally, 2,577 models including the 2020 Tahoe and the 2020 Yukon have been categorized as unreachable, and 26 models have been removed from the recall. These models were remedied in 3 different years, the first group in 2019, four groups in 2020, and two more were fixed in 2021 by these incorrect calibrations in the EBCM which has also presented other software errors in many other GM models.

Laguna Hills, CA. – November 1, 2019 – General Motors recently informed the National Highway Traffic Safety Administration of a recall involving five different vehicle models including the Chevrolet Silverado 1500 and GMC Sierra 1500, all of which share the same defect.

Affected vehicles include:

  • 2015 – 2020 Chevrolet Suburban
  • 2015 – 2020 Tahoe
  • 2015 -2020 Yukon
  • 2014 – 2018 Chevrolet Silverado 1500
  • GMC Sierra 1500 vehicles equipped with a 5.3-liter engine, a 3.08-ratio rear axle and four-wheel drive

The defect

According to the official report regarding this issue filed by GM with the NHTSA, the vehicles involved in the recall contain a defect caused by incorrect axle-ratio calibrations in the vehicles’ electronic-brake control module (EBCM).

The flaw can cause the module to incorrectly calculate the speed of a wheel that has a faulted wheel-speed sensor. In specific operating conditions and vehicles, this can trigger the vehicle’s driveline protection system at an inopportune time.

“If a wheel speed sensor fails in these vehicles, a software error in the vehicle’s EBCM can cause the vehicle’s driveline protection system to activate when (i) the vehicle’s electronic transfer case is set to four-wheel drive or automatic mode, and (ii) the vehicle is driven between the speeds of 41 and 60 MPH,” stated GM’s report on the matter.

“If the [system] activates, the driver will experience unintended braking on the wheel on the opposite side of the failed sensor, which can be considered as one of the many failures that increase the risk of collision in different brands and models.”

Timeline of events

The first report involving the recall arrived May 21, when a GM dealer submitted a warranty report to the manufacturer involving a 2018 GMC Yukon whose owner reported that, while driving between 40 and 45 MPH, the brakes were involuntarily applied and caused the vehicle to pull leftward.

A test of the vehicle confirmed the report, and further investigations revealed all the vehicles which might contain the defect.

“GM and ZF (the EBCM supplier) isolated the condition to certain K2 platform vehicles equipped with 5.3-liter engines, four-wheel drive, and 3.08-ratio rear axles, and to specific operating conditions,”

the chronology report provided by GM explained.

The decision to conduct the recall was made official on Oct. 17. 

The solution

Owners of vehicles involved in the recall will be notified sometime in the near future, although the exact schedule has yet to be set. Authorized dealers will reprogram the EBCM for affected automobiles on behalf of GM, free of charge.
