I have a chance to pick up my sisters 2014 and join my 2008 l322 because of the issues she Is having. The car is in CA and if the outside temperature is 95 + the car on occasion will just go completely dead. This usually occurs after a short stop. Nothing works and the dash goes blank. So, you our stuck outside or just sitting there in 100 degree weather. The dealer found nothing on the 2 times she went in. After awhile the car will go back on and it runs like nothing happened. She is bringing it back in as it just happened again and rather than get screwed on a trade in has offered it to me at a discounted price. The catcher... I live in southwest Florida and it gets mighty hot. If it's a fix or problem I can't find issues like she is having. Am I missing something, is there a known problem?
