2003 Buick LaSabre with only 22,000 miles Highway problems
My late mom passed away and I inherited her car (see subject line above,
Buick LaSabre with only 22,000 miles on it and NO reported prior problems). It
has sat in a garage for a few weeks but started right up this week. I used it to
drive between San Diego and LA and it broke down 44 miles into the trip. It
decelerates from 70, 60, 50......to a complete stop. When it stops the battery
VOLT red light comes on and the interior lights come on. When you pull out the
key all lights go out and nothing comes on (including lights). If you wait for 20-
30 minutes it starts right up as if nothing is wrong. This happens over and over
again without warning. It is very dangerous and unpredictable, since when it
loses power, you have to coast to a stop wherever you are. We have had it into
2 advance mechanic shops that spent hours trying to diagnose the problem
and can't figure out what is wrong with it because they can't seem to get it to
break down like it does on the highway during their diagnostics. One replaced
a main sensor but ended up refunding that, because the same problem
happened again an hour later after they replaced that part. I desperately need
help repairing this, since I am in dire need of this car and operating on very
limited funds. It's also very dangerous to drive because it initially seems
absolutely fine. Does anyone know what might be wrong with it or where I
might take it to be properly diagnosed and repaired in the San Diego area? I
have only a few days to remedy the problem. Thank you in advance for your
help.
