2003 Chevrolet Impala Reviews
not impressed replaced trans cooler at 46000,
transmission at 74000,ABS problems at 88000.
Our 03 is the second of three that we have owned new. The first was a 2000 and the third is a 2007. We love these cars. The ride is better than our sons Honda and the gas millage is 31 to 33 mpg on the highway. The roomy trunk was a factor in purchasing the first one. No major problems with them, except that the 03 needs the AC looked at, almost 84,000 miles on it.
2003 3rd brake job at 50,000 miles.also needs front wheel bearings.
It is an okay car, have had a lot of brake problems with it. Next up is a wheel bearing replacement on the front, can hardly wait to pay for that repair.
We bought this car with 10,000 miles on it in 2004. We now have 62000 miles. The only problem we have had was in 2007,took her to a franchised service center,never again,anyway,Took them three hours to change the plugs(actual work) and they cross-threaded one plug. I didn't know it until a year later when the Chev dealer showed it to me
.. She was running on 5 and 1/2 cylinders all that time,like one cylinder wasn't up to speed..and we thought she was in tiptop condition. We are going to keep her untill,well ever
