My initial thought is Yes... but let me give you the details and hopefully some of you can give me advice...
I have a 1999 Toyota Corolla and for the last 3 mornings, it's been a little slow to crank. 2 days ago and yesterday I had to turn the key twice, both times the engined 'nudged' the first time and then started strong the second. This morning it took 3 attempts... the first time I could hear the car attempt, but the engine didn't budge, the second time it 'nudged' and then the 3rd time it cranked strong and started. It is very early spring here and this morning was indeed chilly... but we just got over much colder temps that had no effect like the last 3 days.
The battery is about 6 months old - is one of those '72 month' or so batteries... supposed to last a long time and I have the receipt in my files at home. When I have left might lights on or when the old battery was having problems, I noticed the 'door is open' indicator would be dim... but when the battery is strong, it lights up brighter. I made sure to actually look at it yesterday and this morning before cranking the engine - very bright so it doesn't look like it's a battery problem - especially after 2 failed attempts that it did crank the engine strong.
The oil was changed about a month (and approx 1000 miles) ago and the engine isn't getting hot when I run it... everything appears normal other then the required multiple attempts to start it.
I appreciate any thoughts on this... I am admittedly not a 'car smart' guy... I'm an IT tech... lol
