My Mom has a 2000 Accent she bought in 1999, 20,000 miles (barely driven). A few months ago she noticed that her lights were brightening and dimming when she went over bumps. Then, this week, her air bag light came on and stayed on. Her 5 yr warranty is over. She took it to the Hyundai dealer...they said her alternator had spiked and caused air bag system damage. She was quoted $950 for alternator replacement and repairs/labor. Seems high...I saw a few posts about similar problems. My questions: how confident can we be in dealer's assessment of problem? Is repair cost out of line? Should she get it checked independently? Thanks so very much in advance for any guidance! Cathy
