The government agency the National Highway Traffic Safety Administration (NHTSA) is opening an investigation about the potential problems of the 2003-2005 model year Z4. The NHTSA has received 107 complaints and one crash report. The complaints and crash resulted from a lost of power steering resulting in difficult to maintain control or loss of control resulting in the crash. The results of the investigation could lead to a recall of the BMW Z4 for power steering retrofit/repairs.

I think the NHTSA sould investigate BMW's electronic steering. It's been well documented that in warmer temps (outside) an adverse condition can occur in the EPS. BMW claims to have fixed the problem with the 2006 model, but I'm not so sure - I can tell you from my own experience that the EPS seems to become "tight" in temps aboove 85 f Under cooler temps I can normally drive the Z4 with one hand a drink a beverage with the other & experience no problems - when it gets warm it takes both hands on the wheel and the slighest movement of the wheel will change the car's direction - in other words it's damn near impossible to hold a straight line. I have learned to "live with it" as all the dealer will tell me is "no faults show" Apparently this condition is much worse in the 2003 - 2005 models.

In reference to the beverage it would be "non - alcoholic" the point I was trying to convey is that the Z4 should easily be able to be driven with just one hand on the wheel. Temps in the midwest have been near 100 f for the past week - hope it's better where you are!! 8)

Besides a performance car is driven with both hands on the wheel :) drink in one hand ... what's next arm leisurely hanging over the side ... :poke: :tumbleweed: :fuelfire: time for a Cadillac perhaps :roll: just thinking here. I like to drive like this :driving: both hands on the wheel

No offense there Mr. Zip :) hope you resolve your issue, keep after BMW
 
I hang my arm out over the side..... :?

Admittedly, I'm not so keen on doing when driving in more demanding situations... but still what's wrong with pretending you're in Smokey and the Bandit?
 
The steering is ridiculous under heat... it's not that it just gets tight.. it's like there is a barrier you have to overcome in each direction to get control. It's about time they investigate this as it just can't be safe in an emergency situation.
