2007 Highlander Hybrid auxillary battery failures

Created September 5, 2010, at 1:13 pm by HoHumHybrid

My car is on its fourth auxillary battery at 13,000 miles. The dealer says my batteries keep failing because I don't drive my car enough to keep it charged (10 to 15 miles every two days). I find this excuse to be ridiculous. If we have to drive our cars every day to keep the battery from dying, then how do we go on a two-week business trip or vacation? If the dealer is correct, wouldn't that mean the dealer has to drive every single hybrid car on his lot every single day before he sells it? And that would mean that every single hybrid car would already have several miles on the odometer at the time its sold as new? I suspect my car is a lemon and my dealer is acting like a used-car salesman. What do you think? Please contact me and let me know about your experiences with your auxillary battery and what you think about my dealer's reasoning. Thanks.

I have a 2007 Highlander Hybrid with 51,000 miles. Clearly, I drive mine a LOT more ..... BUT I also leave it parked for one or more weeks at a time .... and I've NEVER had an aux battery failure. My guess is there's something amiss with the charging mechanism.

My father has an 07 Prius with less than 4,000 miles on it and has had no trouble at all. He drives it far less often than you and only very short trips.

From other forums I have read... Replace the battery with another brand. Do not buy the Toyota brand.
