“Have a 2004 Monte Carlo. Sporadically when driving the speedometer continues to climb. I was following my husband who was doing 45mph and and I was doing 105 then 114 then 120 then 140 then it dropped straight down. It sometimes resets it self and other times it stays like that for days. The car has 42,234 miles on it.”
NHTSA complaint #10410584, filed 2011-07, 42,234 miles“Instrument cluster gauges are not reading correctly. It started with the gas gauge and has now progressed to all gauges in error. Have talked to others and looked on the internet and discovered that this is a very common failure. I consider this a hazard since speed and engine condition cannot be determined. I have not taken it to the dealer yet.”
NHTSA complaint #10249599, filed 2008-11, 41,759 miles“As I was driving my 2004 Chevrolet Monte Carlo ss , last night, I operated the steering column mounted headlight dimmer control. The headlights went out. After wiggling the lever they came back on but I was unable to switch them from high beam to low beam. I've searched the internet and find numerous instances of this occurring. Thankfully there was not an accident related to my incident.”
NHTSA complaint #10370367, filed 2010-12, 54,000 miles“My speedometer and gas gage on my 2004 Chevrolet Monte Carlo are erratic in their readings. Sometimes it will read 100mph while I am not moving, and sometimes it will read 0mph when I am going at least 65mph. I have not had any consequences (speeding tickets or accidents)due to this failure, but it is inconvenient and surely will cause problems in the future.”
NHTSA complaint #10220057, filed 2008-03, 20,000 miles“To the best of my knowledge, any time the wipers, lights, rear-defrost, or when its just cold out, the instrument cluster stops functioning. Notably the speedometer will go up with speed, but not go back down. This also applies to the oil pressure, temperature, fuel and RPM gauges. This defect makes it so I have no idea what speed I am traveling and can be a risk to hazardous road conditions.”
