2003 Saturn L300 Reviews
bought 2003 saturn l300 with 56,000 miles replaced thermostat and 2 oygen sensors.this car runs awesome and the car now has 96k and i will be replacing the timing belt before 100k.I chnage oil every 3k miles
Bought the L300 6 cylinder new and fully loaded. Never had a
new car with this much trouble. Car was nothing but problems from the first week. Dash/speedometer/odometer went out the first week. Steering column had to be repaired three times. 6 oxygen sensors replaced. A/C condensation draining into passenger floor area. Mirrors fell out of side view holders. A/C-heating
temperature control knob had two settings - hot and cold.
Last repair was EMI. Was told then that transmission codes
were troubling to mechanic. I said no way and traded it in
on a new Subaru Legacy. My Saturn had just broken 40,000 miles.
I'm sure someone bought it and felt they got a great deal.
I couldn't sell it to anyone I know so I hope, but doubt, the
new owner got that great deal.
My cousin has a 2004 L300 and it spends more time in the shop
than out. She hasn't broken 40,000 miles. On the other hand,
my sister owns a 2003 L200 and hasn't had any problems.
2003 Saturn L300
I purchased my car in 2005, After purchase My car started smelling like gasoline, after numerous arguments with saturn they finally fixed my car. Here I am today car smells like gasoline again. I am checking to see if there is a recall I will never buy another Saturn ever.
Still love my 2003 Saturn LS300. Have a check engine light, was told it needs to have the thermostat replaced. Dash lights dim regularly. A/C had a problem with the wiring getting crimped causing a malfunction. Not the best of gas mileage right now getting 22-25 in town. Just under 90,000 miles on it right now.
Heard it was going to take 4+ hours to replace thermostat. Anyone have instructions on how to accomplish this?
Also, when bought the car came with no owners manual, any ideas on how to acquire one?
I bough a Saturn 2004 L300 in 2006 with 32000 mi. I have had to do nothing to it except oil change each 3000 mi. and a complete break job at 98000 mi. and tires every year. It is excellent running , suspention is still great, gas milage is still great. My only issue is with the cloth seats, but I am a big man 6' 3' 275#. The left edge of the back wore down from sliding in and out and the padding on the butt broke down. I purchased used Like New Leather seats on the internet and love them. A deer ran into the side my car on the highway killed the deer , No Damage to plastic sides but knocked off the mirror. 250.00 fix. I LOVE THIS CAR!!!
