Tl*- the contact owns a 2004 gmc sierra pick up with a current and failure mileage of 40,000 miles. the contact stated that the speedometer was working improperly. when the vehicle was at a stop the speedometer read that the vehicle was traveling at 120 mph. while driving the speedometer was not registering the speed correctly. the contact would keep up with the flow of traffic to try to gage the vehicles speed. the contact has been to the dealer, and was told that they had to replace the speedometer motor. ak updated 05/23/07. *jb

I have a 2004 gmc sierra. for the last 3 months the speedometer has been acting funny. at times it will say i am driving a lot slower than i actually was. for example, this morning, it said i was going 10 mph and i was probably going about 30-35 mph. i turned off the vehicle and it reset. yesterday while driving on a trip, the speedometer stuck on 75 mph. i did not realize it until cars started passing me on the interstate and when i checked my gps system, it said i was going around 60 mph. the speedometer is just all over the board. sometimes the speed is correct, sometimes its slower and sometimes its faster. i believe this is a real safety concern since the driver does not know how fast they maybe really going. i have checked on the internet and it looks like this is a common problem. *jb

I have a 2004 gmc sierra z71, and the speedometer has begun to perform erratically. it no longer returns to 0 while stopped, and never goes below 35 mph. this has just begun, and apparently judging by the number of similar complaints (over 350 in one forum alone) i have found on web forums this is a very well known problem to gm. *jb

I have a 2004 gmc sierra that the speedometer is sticking. i have found on numerous web sites that lots of people are having the same trouble. apparently the 2004 gmc instrument cluster is having all kinds of problems with faulty gauges. *nm

2004 gmc sierra speedometer gives erroneous readings at highway speed. caused inadvertent and braking, unsafe speed and loss of situational awareness. *nm

I have a 2004 gmc sierra ext. cab truck with about 70k miles on it. in the past week, the speedometer started reading higher than 120 mph while driving. i was only doing around 50 mph. when stopped it reads around 60 mph. i can start and turn off the engine several times and the speedometer needle will drop around 10 mph each time it starts. when it gets to 0, it will read fine for a little while and then gradually start climbing up past 120 mph again. 2nd complaint. around every 20k to 25k miles, i have to take the truck to the dealer and have a new steering column grease packing kit installed because the steering column starts knocking in the engine compartment. the first 2 times it was done was under warranty, now the warranty is up and it needs another packing done. the dealer wants me to pay for this one. this has been an ongoing problem since i bought the truck brand new. *jb

My 2004 gmc sierra 1500 has erratic speedometer malfunctions. i first noticed this on a trip with my speedometer reading 65 mph and all the traffic of a 4 lane expressway was passing me. i then realized my portable gps unit was reading a much slower speed. speeding up to the gaps reading my truck speedometer registered 110 mph. at times the readings are reversed. and at other times the speedometer doesn't work at all. after research on the internet i?ve discovered gm has used faulty ?cluster stepper motors? and many customers are having this same problem and gm knows about the problem. fortunately there haven?t been any reported deaths yet due to the problem one would hope that a recall would result before there are fatalities. *jb

2004 gmc sierra pickup speedometer is very erratic. indicated speeds are not accurate. sometimes speedometer indicates 40-60 mph when truck is not moving. *nm

Speedometer gauge is showing wrong speed went to local dealership and they said they have had many complaints but it is not a recall and price to fix is $450-$550. *jb

2004 gmc k1500 z71 - speedometer reads incorrectly 0-100 mph off of actual speed. *nm

The speedometer is not working correctly. the speeds shown on the speedometer have nothing to do with the actual speed of the vehicle. *jb

Speedometer fails to reset to zero. when vehicle comes to a stop, the speedometer indicator stops at a speed above zero (i.e., 30, 40, 50 mph). when the vehicle resumes traveling, the speedometer indicator starts incrementing at the speed at which it stopped (i.e., 30, 40, 50 mph). therefore, the indicated speed is much higher than the actual speed. this is not one incident, but an ongoing continuous problem, and very dangerous. *nm

I have a 2004 gmc sierra that has a malfunctioning speedometer. it shows reading anywhere from 0-100 mph over what you are traveling at. with the truck turened off - the speedometer will show it at speeds of up to 100 mph. this all started at about the 40,000 mile mark. we previously had a 2004 chevy 5500 truck that too began w/ speedometer trouble at the 40,000 mile range. we know several other people with a 2004 chevy/gmc all of whom have this same problem. checking around the internet and it appears that this is a huge problem that should warrant a recall before something tragic could happen.

2004 gmc sierra at 50,000 miles developed a speedometer short in the instrument cluster which caused wild swings in mph readings. after mentioning it to a friend with a chevy silverado, same year and mileage , i found he had the identical problem . i had the cluster replaced at my cost.*jb

My speedometer on my 2004 gmc sierra has become erratic. sometimes it is zero even if the vehicle is moving. sometimes it registers 120 mph sitting still. it is very difficult to judge speed in school zones. no know events led to the failure. the repair bill will be about $500 i am told. *nm

Speedometer acting erratic, speedometer may register 120 mph when i'm going 60 mph. then it finally quits. it costs a lot of money to get replaced. i do not know how fast or slow i'm going which endangers me and everybody around me. *jb

My speedometer on my 2004 gmc z71 works erratically. sometimes it will peg out at 120 or it sticks at 70 mph. when i see the speedometer, it seems like it is working like a clock. it sticks and releases. *nm

Speedometer is erratic in function i have 44,000 miles on my 2004 gmc sierra and the speedometer is in need of repair or replacement. *nm

Dt*: the contact stated while driving various speeds, the engine stalled without warning and would not restart. the vehicle was towed to a dealer who determined the ignition harness needed replaced. after the ignition harness replacement, the problem persisted. the vehicle is currently awaiting further inspection by the dealer. the manufacturer was alerted.

My gmc sierra crew cab k1500 z-71 speedometer began malfunctioning around 37,000 miles. it will stick at 0, or sometimes at 20 or 50. the problem is intermittent and gets better sometimes if i stop and turn off the engine. now volt meter is not working properly. this is a safety hazard, since i can't tell the mph that i am driving. i regularly carry my 2 small sons and this is quite scary. i have noticed that this is a recurring problem with many gm products this age. general motors has a major problem here ! *nm

Speedometer not working properly. *nm

Speedometer does not work. *tr

Tl* the contact owns a 2004 gmc sierra 1500. while driving approximately 35 mph, the instrument panel failed without warning. the failure recurred on numerous occasions. the vehicle was taken to a dealer and independent mechanic. the vehicle was not diagnosed or repaired. the manufacturer was not made aware of the failure. the approximate failure mileage was 30,000.

Tl*the contact owns a 2004 gmc sierra 1500. the speedometer worked intermittently and displayed inaccurate speeds before completely failing. the vehicle was under warranty, but the dealer stated that the failure was not a warranty item. the vehicle was not repaired at that time and has since worsened. general motors has a letter of intent on the instrument panel, but because the vehicle has exceeded the 70,000 miles specified in the letter, the contact was denied the repair. the current mileage was 98,000 and failure mileage was 60,000.

I have a 2004 z71 sierra truck with a 5.3 engine that has a speedometer problem. it reads 120mph all of the time and they have quoted me around $550 to fix. i also have a clunk in the steering wheel when turning. i have had this problem fixed once by warranty but it has returned again. *tr

Speedometer displays erroneous readings, never correct. *nm

Upon entering the vehicle there was no power. aaa was called, and it would not take a jump. the dealer repaired the battery cable bolt that became defective from acid. the battery cable prong and wires were replaced at consumer's expense. *ak *sc *jb
