QUESTION: I currently own a 2009 Jeep Wrangler Rubicon. The Jeep has been trouble free. I am interested in a 2012 and have been told the all-new engine is better than the engine I have in Jeep.


ANSWER: There is no question that the new 2012 Rubicon is much improved over the predecessor. Start with the new V6; it is quiet, smooth and has plenty of power, all with increased gas mileage. Our test Rubicon had a lot of options, including navigation, heated seats and more. If I were to buy a Rubicon, I would need a second set of tires and wheels for everyday road use. The factory-supplied tires are for off-road, mud, etc., but these tires are not made for daily highway driving. No matter which Wrangler you buy, you will be happy.


 


QUESTION: I own a 2003 Saturn Ion with 182,000 miles on it. Starting last year, my car will not start on cold mornings. I have no problems in the summer. When I first try to start the car, it sounds like a dead battery (battery is only 1 year old). I wait a couple of minutes, and it will almost start. I have to do this several times before the car will start. What’s going on and what can I do about it?


ANSWER: The first step is to check the battery with a tester and then the actual battery voltage in the morning before trying to start the engine. Second is a look at the coolant temp sensor before trying to start the engine. Make sure you are using 87 octane, not the 92 or higher. A higher octane fuel can cause long cranking in cold temperatures. In some rare cases carbon buildup on the back side of the valves can also cause hard starting on cold mornings.


 


QUESTION: I own a 2010 Toyota Camry. Last week the low-tire pressure light came on the dash. A couple of days later it went out. What is the problem?


ANSWER: When the temperature drops down so does the tire pressure. I see a lot of vehicles every day, a lot with the low tire pressure lights illuminated. The most common problem is just a low tire. Most vehicles equipped with a full-size spare tire also need to have the spare checked because the computer also monitors the spare tire pressure.
