Steering Problems of Porsche 911

This is a 2025 Porsche 911. The car came equipped with "land keep assist" also referred to as "lka". In operation it is at times terrible, and at other times genuinely frightening. The system, without warning, intervenes to change the direction of the vehicle by applying steering input. It is very, very, inaccurate and unreliable. When engaged it often is fooled by gaps in road paint markings and similar imperfections. Unlike electronic stability control which intervenes to assure you can maintain the line of travel suggested by steering wheel position, this system makes an independent assessment, one which in my experience is often wrong. It gets worse. In the control screen, lka is a feature that you can check into the "off" position. The problem with this is the system resets on its own without a command from the driver. I have not figured out what causes this, whether it is time between use or some other measure. This reset happened to me yesterday. I was driving the car and the steering felt odd, with play in the feedback. Very, very disconcerting in any car, let alone a sports car where the driver wants the car to go where commanded. In my case, this uncertain feeling was felt on the golden gate bridge where the lanes are very narrow (and the lka system is very easily fooled). After a few minutes of the odd feeling I opened the menu on the center screen and saw that lka had been ticked back on. A very close friend of mine has a 2025 Porsche cayenne and has described the same problem. As noted above, I am very familiar with esp systems and value them. I also own another car with a lane keep feature (an Acura) but which is accurate and only is applicable when I affirmatively enable the feature while using the adaptive cruise control. While I would love for the ability to remove this feature, at a minimum when the owner exercises the election to turn it off, it should stay off -- I. E. , not reengage without warning only to surprise the driver.

I was driving on a 16 lane major highway in toronto in the express lanes at 70 mph. Without warning the engine lost all power and stalled. The check engine light was flashing. It was difficult to stop safely since the power steering and power brakes were not functioning with the engine stopped. It would not restart and I was lucky to change lanes in heavy traffic and pull onto the hard shoulder of the road. I was stuck sitting in the express lanes by a guard rail until a tow truck came, which took an hour. After taking it to the Porsche dealer it was diagnosed as a ims bearing failure that required a new engine. I was also told this bearing is a common problem with the 1997 to 2008 water cooled 911 and boxster Porsches with a 10 percent failure rate to date, and that they will all fail eventually. The dealer also said there is a 3rd party retrofit kit that the Porsche dealers are aware of but don't use because it would acknowledge there is a problem with the car, so Porsche turned a blind eye and let the engines fail. Porsche has modified the bearing design several times before abandoning the design in the 2009 model year. All these models are unsafe when they will fail without notice and put drivers in harms way.
