I live in the desert. Have had full regen since spring. Went camping last weekend. 38 degrees at night. Woke up to the sun. Full regen. -- Tonight I went to get my car from SC. Had some rattles fixed. 71 degrees. Got in. NO regen - the kind I only saw in the snow last winter. Drove home in traffic, 69 degrees. Didn't get regen back. Drove around at night in 68 degrees. Still wont come back. Anyone seen this? What did they do to my car? Does it have to do with charge being in the 90%s?
