GM Joins Recall Bandwagon with 1.5 Million Cars

ebay 066

This is turning into a rough week for American automobile manufacturers as two of three major companies placed vehicles on the recall list. While the Chrysler Group started this work week with three separate recalls affecting just under 600,000 vehicles collectively, General Motors has most recently eclipsed Chrysler’s vehicle total. Announcing a recall of 1.5 million cars, General Motors is addressing an issue which resulted in at least 5 vehicle fires.

Early Tuesday, GM sent out a notice informing owners that the electronics within the windshield washer fluid heater was prone to short circuit causing an overheat. Surprising enough, this GM recall is not the first one for the washer fluid heating system. In September of 2008, the exact same 2007 and 2008 model year vehicles were addressed then by the installation of an electrical fuse. This time, GM dealerships will remove or disable the washer fluid heater unit altogether. This election to remove the system rather than repair the heater is mainly because GM’s supplier of the technology, Microheat, declared chapter 11 bankruptcy in late 2008 and is unable to furnish a remedy.

GM products affected by this recall includes the following vehicles:

Buick

2006-2009 Lucerne
2008-2009 Enclave

Cadillac

2008-2009 CTS
2006-2009 DTS
2007-2009 Escalade (All models)

Chevrolet

2007-2009 Avalanche
2007-2009 Silverado
2007-2009 Suburban/Tahoe
2009 Traverse

GMC

2008-2009 Acadia
2007-2009 Sierra
2007-2009 Yukon

Hummer

2006-2009 H2

Saturn

2007-2009 Outlook

Removing the system, which was once an award-winning automotive innovation, GM will also compensate each owner for the amount of $100 in exchange for the windshield washer fluid heater. This price is more than fair compared to the fact that the heated washer fluid system was only an $85 option on the 2007 Chevrolet Suburban.

With GM’s news today joining the news yesterday that Chrysler Group is recalling Jeep Wranglers for potential brake fluid leaks and Chrysler minivans for concerns of possible sliding door electrical fires, some might be under the impression that the American auto industry is returning to their low quality aspirations. That notion is as much a mistake as the dogma that Japanese vehicles are indisputably reliable. Recent overall quality reports have been proving this fact. When buying an American car, at least the saying ‘they don’t built them like they used to’ can be a source of solace.

  1. the automotive industry, in this period of multiple recalls of cars from the little to luxurious are tackling the safety issues.

    To keep the heavy tech talk to a minimum, the internal parts such as engine controllers, are being developed with new Safety Standards (ISO 26262) which address the issue of systematic failures and random hardware faults. These are faults which take down the cars engine systems controllers. They reduce the “availability” of the system and thus create potential risk conditions for drivers.

    They mainly occur within the micro-chips (Systems on Chips, SoCs) which now have millions of transistors inside, all connected via wires which are nanometers wide. The car system problems are becoming more frequent because these micro-chips are using ever decreasing Deep Sub-Micron Technologies which augment the probability of failure of physical parts purely due to their “small size” e.g. things like voltage spikes ruining transistor substrates.

    So, how are these issues being addressed? Well YOGITECH S.p.A (a small 25 person company) saw this phenomenon coming more than 4 years ago and patented a method for both analysing and designing “Fault Robust” micro-chips which can detect and sometimes correct errors within microseconds of the problem occurring. Yogitech’s technology is now allowing companies, which design engine controllers for car makers for example, to produce designs which are “Fault Robust” and as such increase their “availability” and therefore drastically reducing the probability of risky downtime.
