2005 Chevrolet Monte Carlo: adaptive cruise control problems

Filed Apr 18, 2016 · Electrical, Fuel system · 65,000 miles · CO

I began having trouble with this car a few months after I purchased it. I can't drive the car at night with the lights on bright, because when I do the lights shut completely off and the only way to get them to come back on is to flip the dimmer switch. I have been on the interstate and highway both, driving the posted speed limit when this has happened. This problem, in my opinion is a big hazard and very unsafe. I had to have the cruise control switch replaced, the instrument panel replaced, because it failed completely while I was going on vacation, I had no idea how much gas was in my car or what speed I was going all gauges were out of whack. The car smells like gasoline, I've taken this to the dealer auto repair shop, they claim they can't find the problem, even though they could smell the gas both on the outside and inside of car. There was a recall on the key, I took into dealer and they put a cover over the old key, I personally don't understand how that was supposed to take care of whatever the problem was. I have noticed that others on here have listed similar complaints about this car. What I'd like to know is, if there are so many people having the exact same problems with these cars, why hasn't there been a recall issued? I can't speak for anyone else, but I paid hard earned money for this car and I'm sick and tired of having to constantly repair stuff, which seems to be a big problem on this make and model. I think something needs to be done before someone gets seriously injured or worse. And it shouldn't take someone's life before something is done about this.

A yr. Aft. I bought my 2005 monte carlo, things began going wrong with it. First 2 things to go:the cruise control & re-window defroster. The next yr, while driving at night on the interstate, I switched my lights to brights & within seconds I had no lights at all! This could of caused a very bad accident, I was able to quickly switch the lights back to dim & luckily they came back on. Since then, I no longer use the bright lights, for fear of my lights not coming back on. Then it seemed like everything went haywire after that, odometer showed that I was going 110, gas gauge quit & temp gauge registered past 260. Not a fun night to be driving, not knowing my correct speed, how much gas I had, if my car was going to overheat or have no lights! Since 6/15/2012 the tach now registers between 6000-7000 rpms & none of the gauges are working properly. My car also smells like it has an exhaust or fuel leak which comes thru the vents, it makes me sick & gives me headaches. I took it to a dealer a yr. Ago, paid $98.00 for them to tell me they couldn't find a problem. To this day, my car still smells like gasoline, I pray it doesn't catch on fire. Tonight I've been researching these problems & found that the faulty gauges is a very common problem with these cars & quite expensive to fix. I feel chevy should be held responsible for repairing this problem & all the others, after all they're the ones who built a car with many serious problems. This is very unfair for the many consumers out there who have spent their hard earned money to buy this car. Not everyone can afford to get this fixed along with paying the car payment. I don't understand why they can't be made to take care of this. What would have to happen in order to make them pay? What's listed above? A crash, fire, injury or death? Shouldn't have to be that way, something needs to be done before any of that happens!

The speedometer and tachometer in my wife's 2005 chevrolet monte carlo started showing the wrong speed when we were driving on the highway. I set the cruise control at 75, yet the speedometer said I was going over 100. At first the problem was sporadic, then became continuous. I took the car to a local dealership and had the instrument cluster replaced for about $460. When I bought the car, I also purchased an extended warranty, so I had to pay $200 of the original bill, however this seems to be a well-known problem over several years of gm products. There had not been any accidents while this was out, but my daughter received a speeding ticket and I received 2 warnings for speed, all while driving in town.

I was driving on the highway, and slowed down as I entered a town. Once I got back onto the highway, and reset my cruise control, my speedometer read at 90mph. I was not going that fast. Once I got stopped, I could see that my speedometer was reading at 30mph while in park. The problem has continued. At times, the speedometer reading will never go past 0mph and at others, it will read at 120mph when I first start my car. It will show that I'm accelerating and decelerating, but will fail to return to 0. I can also hear a clicking noise when it decelerates. At this point, I'm estimating how fast I'm going based on where my RPM gauge reads at. The only component to fail is the speedometer.

October 27, 2009 was the 3rd time in 4 days that the speedometer and tachometer have stopped working while driving or failed to work period. I don't know what LED up to the failure it just started when I was driving home from work on friday october 23, 2009 and my cruise control was set at 65 MPH and I noticed my car started slowing down and I was almost rearended I gave the car some gas and I noticed that my speedometer wasn't working nor was my tachometer. I haven't had anything done to correct the problem. I searched the internet and I have noticed that many many people have had this issue with 2002 through 2005 monte carlo's. This is a very dangerous problem that needs to be addressed. This will eventually take a life if not addressed and fixed by chevrolet. There is clearly a huge problem that must be recalled. I had a 1999 chevy silverado that was recalled for faulty tailgate support cables. This problem is much more serious than that was and it was recalled so why not this? The instrument panel in a car is the drivers information center and a huge safety concern if it is proven to be faulty. Speed control is required by all states and if a car manufacturer has an issue this big with one of its products then it needs to be addressed and not hidden. This problem is also present in many other gm vehicles as well. Research it I did and I know there is a huge problem. I am sure you can reach the same conclusion. Took me only 2 hours of research for me to react. How long will it take the government? Maybe never since they now have a vested interest in gm or maybe a few huge lawsuits against government motors will change its mind.

Tl*the contact owns a 2005 chevrolet monte carlo. While driving approximately 70 MPH on normal road conditions, the cruise control mechanism was activated. Unexpectedly, the speedometer and RPM gauges failed without warning. The vehicle was taken to an authorized dealer for diagnostic testing and they stated that the instrument panel failed. The instrument panel was replaced. The VIN was unknown. The failure mileage was 51,000 and current mileage was 52,000.
