ENGINE AND ENGINE COOLING
01/15/200758980109/20/2005
 I have a 2003 chevy avalanche z71 with 59000 miles. i noticed my vehicle being very sluggish the day before. when i left for work, i could barely get up to 50 mph, in order for me to stay at 50 mph i would have to reach 3000 rpm. after i turned down a side road, i could only get up to 20 mph at 3000 rpm. i pulled over and called for help. i took it to a chevy dealership. they found the intake gasket was bad which caused the converters to fail and clog up the y pipe. it's hard to believe this happened with only 59000 miles. i take great care of my avalanche. i've read on forums where there is a lot of people that is having the same problem with the same type of truck and year. the dealership replaced the gasket, both converters, y-pipe and the o2 sensors. *jb

 Engine uses 1 qt per 2k miles of engine oil, according to dealer this is acceptable, but if not noticed or checked it could lead to engine failure. i would have not bought the truck if it said engine burns oil. *nm

 Pick a problem. pin from transmission gears were too short from the manufacturer, causing the transmission to not shift properly. this repair was done at 8000 miles. 4 quarts. low on oil within month of changing. no leaks and no explanation from the dealer as to where the oil went. a/c functioned improperly after truck surged at traffic light. still no explanation. remote entry works when it wants to. interior lights pulse when truck idiling. heater motor functions according to speed of vehicle, slow when braking and speeds up when accelerating. drivers power window stopped functioning and started working the evening before taking it to the dealership for repair. popping noise from exhaust just after starting and shutting off. from inside the vehicle while running i continuously hear cooling fluids flowing. sometimes the horn does not function while the vehicle is turned off. braking has always been a problem from day one. always feels as there isn't enough brake pressure to stop in a normal distance. along with the remote entry not working the personal presets for driver 1 most of the time do not operate with the remote entry. i have to select driver 1 from the interior to engage settings. bed plastics are fading. buttons for radio on the steering wheel and radio are flaking. *ak
