2001 Nissan Sentra 176,000 mi,
Battery when dead a few days later. I replaced the battery and no more problem, tho I didn't know it would correct the power problem.
2000 Nissan Sentra 95,000 mi,
Just after I purchased this car used I found that sometime it would stay in third gear. I replaced the battery and the problem was completely resolved.
My car started sticking in 3rd gear when I would start it cold or hot and the O/D light would flash, I also noticed that it was sluggish to turn over when starting which indicated a bad battery. Fortunately I read on this site that others had a similar problem and fixed it when the battery was replaced, I replaced my battery and the problem stopped. Thank you for posting this information and saving me time and money.
