Two things I noticed starting with the first issue was the tires exhibited symptoms of flat-spotting. This was one thing I was looking for considering the car sat on the lot for such a long period of time. Long periods between test drives were the likely culprit. The second issue was when I came back to test drive again and ultimately purchase the vehicle, it was discovered that the battery was dead. They had to jump start but I requested a new battery, which they happily did. They weren't going to lose a sale due to a battery situation. Flat spots on tires can be a common things for cars that sit for long periods and I made sure before signing the contract that if the tires didn't even out that they would be replaced. I had this written into the contract. Again, I wasn't concerned but they wanted me to feel confident in the purchase. As for the battery, I chalked it up to it having sat for so long or any number of things.

HOW LONG DO LEXUS BATTERIES LAST?

Lexus batteries usually last between 3-5 years, but this is variable depending on the type of battery, driving habits, weather conditions, and more. You can prolong the life of your battery by:

• Proactively testing your battery
• Keeping your vehicle stored indoors away from extreme swings in temperature or climate
• Keeping the battery tightly fastened - did you know the vibrations of your car can loosen the connections and rattle your battery's components?
• Cleaning the terminals and posts of corrosion with the contractual cleaning interpretation & a wire brush.
• Starting your Lexus mostly is essential. Don't let your battery go unused for long periods of time.

HOW OFTEN SHOULD YOU REPLACE YOUR LEXUS BATTERY?

Every 3 to 5 years, but you should have your battery tested frequently for drops in voltage to make sure it's operating at a high level. Car batteries typically carry 12 to 13 volts unless you have a high-performance battery. Anything higher than 13 volts may indicate a faulty battery.
