2006 Cadillac STS problems

What is wrong

General Motors LLC (GM) is recalling certain model year 2004-2007 Cadillac CTS-V vehicles manufactured October 6, 2003, to March 15, 2007, and 2006-2007 Cadillac STS-V vehicles manufactured June 23, 2005, to March 15, 2007. In the affected vehicles, the electrical terminals of the fuel pump module may overheat resulting in the melting of the flange material.

Risk

If the flange melts, a hole may be created allowing the fuel pump to leak fuel, causing the vehicle to stall, increasing the risk of a vehicle crash. Additionally, leaking fuel in the presence of an ignition source increases the risk of a fire.

Remedy

GM will notify owners, and dealers will replace the fuel module and fuel tank jumper harness, free of charge. GM sent out interim notices in late October. The recall began on March 12, 2015. Owners may contact Cadillac customer service at 1‑800‑458‑8006. GM's number for this recall is 14405.

On certain passenger vehicles equipped with all wheel drive and a 3.6l v6 engine, the torque monitoring functions of the electronic throttle control (etc) are not enabled. These functions can limit engine speed and torque if unusual engine control module (ECM) hardware or software failures occur.

Risk

Without these functions enabled, a persistent ECM failure could result in a throttle opening greater than commanded by the driver and a crash could occur.

Remedy

Dealers will reprogram the ECM on these vehicles free of charge. The recall began on january 24, 2006. Owners may contact cadillac at 1‑866‑982‑2339.

Odi evaluated two different alleged defects involving rear drivetrain components during this preliminary evaluation.gm is conducting a recall to address one of the defect conditions and odi has opened an engineering analysis to continue its investigation of the other alleged defect. On december 19, 2007, gm submitted a defect information report to the federal safety agency concerning defective rear axle pinion seals in approximately 275,936 model year (my) 2005-07 cadillac cts, sts and srx vehicles as well as my 2006-07 pontiac solstice and my 2007 saturn sky vehicles (recall 07v‑589).on sts and srx vehicles with all wheel drive, the front axle pinion seal also does not meet all of gm's specifications and may experience a fluid leak.gm indicated that the seal supplier made an unauthorized change to the pinion seal material.leaking pinion seals could result in loss of rear differential lubrication which could result in rear wheel lock-up and loss of vehicle control. On december 7, 2007, odi opened an engineering analysis (ea07-017) to investigate complaints of rear drivetrain component failure (e.g., fractured rear differential carrier housing or rear axle half shafts) while driving in approximately 7,600 my 2004 through 2006 cadillac cts-v vehicles.this condition may result in a loss of motive power and vehicle disablement and is not addressed by recall 07v‑589.odi identified 35 complaints (16 to odi and 19 to gm) and 128 warranty claims potentially related to this condition (see ea07-017 opening resume).these complaints are not included in the failure report summary of this closing resume.
