I bought my 2004 L300 in November 2004. I started having problems with it less than a month later.
While driving on the highway at 65mph+ it all of a sudden stalls out. It will lurch forward and not allow me to accelerate. I have to turn on my hazards and make my way to the shoulder of the road where, sitting idle, it has what can only be described as convulsions. I turn it off, wait a few second and turn it back on. It starts right up like nothing was ever wrong with it, except that the SES, car/wrench light and another light on the right side of the dash come on. Of course this almost always happens on the weekends when dealerships are closed and I am out of town.
Unlike some of the posts on here, my dealership has been nothing but kind, helpful and understanding. I have not had to pay for them to try to figure out what is wrong, and they have provided me with a rental car each time they needed to keep it longer than a day.
My car has been in the shop since Tuesday and it is now Friday. They have not been able to get it to act up for them (of course). It seems to only want to break down on me. I will be getting it back today to go on another trip. I have already found other dealerships close to my destination, so that if it does stall on me again I can get it somewhere before the codes disappear.
