(Adds details on Cadillac, NHTSA consumer complaints)

DETROIT/WASHINGTON, April 16 General Motors
engineers reported accidentally turning off ignition switches in
a Cadillac SRX with their knees more than eight years ago, and
they ordered a similar fix to a similar problem in smaller,
cheaper cars linked to 13 deaths, according to documents from
parts maker Delphi Automotive.
The documents, provided to U.S. safety regulators, show GM
used the same part, from the Cadillac Catera sedan, to
make ignition switches more difficult to turn off on the 2007
Cadillac SRX crossover and the 2007 Saturn Ion and Chevrolet
Cobalt sedans. Delphi supplied the GM-designed switches for all
of those models.
The documents are the first indication that GM's luxury
Cadillac brand experienced ignition-switch problems similar to
those that triggered the recall earlier this year of 2.6 million
GM compacts, including the Cobalt and Ion.
GM did not immediately respond to requests for
The Delphi documents, released on Wednesday by the
U.S. National Highway Traffic Safety Administration, also may
indicate that earlier versions of the Cadillac SRX, from model
years 2004-2006, used a switch part from the 2003 Ion. One
document says the SRX "in the beginning of the program" used
switch parts from "Delta" vehicles, the code name for the GM
small-car family that includes the Ion and Cobalt.
The original SRX ignition switch part also was used in the
2003-2007 Cadillac CTS sedan, according to online GM parts
catalogs reviewed by Reuters. Delphi told NHTSA that it supplied
the switches for the 2003-2007 CTS and the 2004-2009 SRX.
The Delphi documents did not make clear whether earlier
versions of the Cadillac SRX had ignition switch issues. Neither
the SRX nor the CTS has been recalled for ignition-switch
related issues. GM did not immediately respond to request for
The original Cadillac ignition switch and the original
Saturn ignition switch carry similar GM part numbers: 12450257
for the 2004-2006 SRX and 12450250 for the 2003-2006 Ion.
GM requested a change to the Cadillac SRX ignition switch in
early 2006, months before the relatively unchanged 2007 SRX went
into production, because "test drivers (were) turning off the
car with their knees while driving," Delphi told NHTSA.
GM engineers experienced similar issues in the Ion and
Cobalt, but several times rejected design changes to the
ignition switch until 2006.
The Ion and Cobalt were not recalled until 2014, despite
NHTSA receiving hundreds of consumer complaints over the past
decade about engines stalling in those cars.
GM sold far fewer of the Cadillacs -- just over 200,000 CTS
sedans and nearly 60,000 SRX crossovers from 2002-2005.
NHTSA received at least a dozen complaints about engines
suddenly stalling in the 2003 CTS and another nine complaints
about engines stalling in the 2004 SRX, a Reuters review of
NHTSA complaint data show.
There are many potential reasons an engine could stall, and
most of the complaints do not specify ignition switch issues.
Some referred to the engine stopping when hitting a bump, which
can be a switch-related problem in recalled vehicles.
The driver of a 2003 CTS, in a complaint filed in April
2014, described an incident in February 2006 where the engine
would shut down "when the vehicle would hit a pot hole or hard
The same driver, after hearing recent reports of ignition
switches being jostled or bumped off in other GM cars, said, "I
went out to my vehicle and started it, put the vehicle in drive
and smacked my key ring and the vehicle stalled."
In a complaint received in 2004 about engines stalling in
the 2004 SRX crossover, another driver said that the vehicle
"goes from 65 mph to 0 (and) you have no control over the car at
The complaint database does not include names or contact
information. NHTSA did not respond to a request for comment on
the Cadillac switch or consumer complaints.
