Buick La Crosse Stalling/Starting Problems



  • My 2011 Lacrosse is at the Dealer. They are a wonderful dealership (Ingersoll in Danbury ct) Car kept stalling and running very rough. Right before I brought it in my change oil light came on. I told them to change oil while there. My car has 30,000 miles on it. I had it changed last at 25,600. The dealer called today and said it was stalling and running rough because the oil was down 2.5 quarts and that is why it was stalling and running rough. If the oil was so low and causing these problems then why didn't the check engine light come on? Makes no sense to me or my husband and a friend that is a mechanic. There is no leak. I get my oil changed every 5,000 miles. Not happy with the outcome. I don't believe that i s the problem but if it is and the oil was that low, then why didn't check engine light come on?

    2006 Buick LaCrosse CXL with random stalling issue - this started around 67K miles, now just over 70K. The engine just quits - totally randomly. When this happens the interior - including all guages - behaves as if the key is turned to the off position. While coasting I am consistently able to shift into neutral and re-start, continue on as if nothing happened. Dealer could not re-produce problem and only charged $60 for the "diagnosis". After much research I have replaced several parts commonly known among mechanics to cause this problem. I have switched out fuses, replaced the crank shaft sensor and ignition control module, examined and tightened every connection I could find, grounded engine block directly to battery negative terminal. Thought I had the problem fixed with the direct ground as I had no stall for almost 2 weeks of regular driving. Then last night it happened again. We can't be repeat GM customers if GM kills us on the highway! Will try replacing the ignition switch (my original suspect) next.
