| The speedometer needle sticks after several hours of driving (long trips). the needle has stayed stuck at 70 mph when comming off of the expressway until almost at a complete stop. it has also stayed at 20 - 30 mph when the vehicle was going about 50 mph. dealer and chevy will not authorize repairs until condition can be replicated by the service dept. given the intermittent nature of this important safety device failure, it is no longer safe to drive the vehicle for long periods. unrelated problem, both outside rear view mirrors vibrate in the wind making it difficult to see objects in them. *ak | |||

| After traveling for long periods of time on a highway and then slowing to a stop on the exit, the vehicle hard shifts in gears 1-2. if you shut off the engine, it appears ok until the next time. transmission fluid is ok. vehicle only has 47500 miles. had mechanic check and gets computer code 1870, with engine check light on. numerous posts on the web have similar complaints on chevy/gm vehicles with 4l60e transmission, but no recall to date. may now have to replace transmission. | |||

| I took my van in under warranty because my abs doesn't work. my rear axle clanks and winds. two weeks after i bought it these problems started to occured. i took my van into the dealer ship right away and they replaced my rear axle. the problem with the axle still exists but was worse after the replacement of the axle. the problem is progressing and i will be in need of a new axle soon and have never had abs since i have owned the van and the dealership wouldn't repair the problems. they tell us there is nothing wrong with the abs or the rear axle. they tested my brakes by driving my van around the parking lot. my front brakes are spongy and they lock up on wet roads when braking hard. this is a 1999 chevy express van. we also purchased a 1999 chevy monte carlo sight unseen at the same time we purchased our express van. we had problems with the front end alignment of the monte carlo and it was the tread off of the left front tire after two thousand miles. they kept telling us there was nothing wrong with the alignment after taking the car to the dealership numerous times. jim cox tried to tell us that my wife made too many left hand turns and insulted my wife about her weight neither vehicles were ever titled before we purchased them. problems on both vehicles started to occur immediatly and we have had nothing but trouble with trying to get the warranty work done on them. now the warranty has expired and the problems i have had with my van still exists and is becoming increasingly worse. jim cox was the area service represenative for all of central florida chevy dealerships and told the service manager if it's not broke don't fix it and he had no problem stating that right in front of my wife and myself. called head office thay did not whont to nkow, never ever buy cheve ever ever again. *ak | |||
