I have had numerous lights, noise, continuously for the last 7 years have replaced numerous parts, only to last awhile then the lights, noise return. Seems there is no cure for this malfunctioning problem, have heard GM is aware of these problems but have never received a letter regarding them, the anti-lock traction control braking system on these cars are headaches and troublesome, and expensive with no cure in sight, have spent tons of money on these problems, still keep having them.

Specific symptoms reported on the 2005 Chevrolet Monte Carlo
Recalls 1
Electrical system: ignition
- What is wrong
- This defect can affect the safe operation of the airbag system. Until this recall is performed, customers should remove all items from their key rings, leaving only the ignition key. The key fob (if applicable), should also be removed from the key ring. General Motors LLC (GM) notified the agency on July 3, 2014, that they are recalling 5,877,718 model year 2000-2005 Chevrolet Impala and Monte Carlo, 1997-2003 Chevrolet Malibu, 2004-2005 Malibu Classic, 1999-2004 Oldsmobile Alero, 1998-2002 Oldsmobile Intrigue, 1999-2005 Pontiac Grand Am and 2004-2008 Pontiac Grand Prix vehicles. In these models, the weight on the key ring and/or road conditions or some other jarring event may cause the ignition switch to move out of the run position, turning off the engine.
- Risk
- If the key is not in the run position, the air bags may not deploy if the vehicle is involved in a crash, increasing the risk of injury.
- Remedy
- GM will notify owners, and dealers will install two key rings and an insert in the key slot or a cover over the key head on all ignition keys, free of charge. The recall began on September 9, 2014. GM's number for this recall is 14350.

What 2005 Chevrolet Monte Carlo owners say
Most recent owner complaints, unedited.
The PCM for the transmission is out or defective and from what I've researched this is a very common problem with the monte carlo. Chevrolet should be responsible for selling a known defective computer!
Takatarecall stil till I have that problems
When I first bought this car the boost gage was not working. A few days later the gas oil pressure and temperature gauges started going crazy. The temperature gauge needs to work to show overheating of engine to avoid damage. Internet forums say this issue a very common issue. Picture shows gauges on left after car running 10 min with approx half tank of gas
The multi function switch is faulty. My blinkers never work right. Sometimes I have right and no left turn signal and many times the hazard lights turn on when I use turn signal. The turn signal sound of clicking never stops, constant clicking that often starts buzzing. Quite often my turn signals do not function properly and I have no way to alert other drivers that I am switching lanes. It seems to be a common problem with chevrolet and gmc and expensive to correct.
Feul pressure regulator recall #07e021000 for 2005 impala, but not for my monie carlo , gas smell while driving/fuel pressure regulator leaking.
Tl* the contact owns a 2005 chevrolet monte carlo. The contact stated that the key failed to turn over in the ignition so the contact was unable to start the vehicle. The VIN was included in the federal safety agency campaign number: 14v400000 (electrical system). The manufacturer was notified of the failure. The contact was waiting to be referred to an authorized dealer to diagnose the failure and provide the recall remedy. The failure mileage was not available. Parts distribution disconnect.
My car has a strong gas odor particularly in colder weather. I noticed it last winter and it went away during the summer. Now that the temps are getting cooler, it has started again. I turn on the heat and have to drive with the windows down for ventilation. I've had three different mechanic shops check it out. None have been able to find the cause. It is embarrassing in the school car rider line or in a drive through. Someone always comments on it. I am worried it may catch fire.
My engine (v6 3.8l 3800 series) is leaking oil on the engine. My mechanic told me this yesterday (11/2/16) when he replaced the plastic elbows as I had antifreeze leaking from them. He said the 3.8 l engine has a recall for this, oil leaking from the valve cover gaskets and said chevrolet has a recall to replace them. I do remember seeing this recall online somewhere, but have not seen it while searching the last two days. My mechanic old me it will cause a fire. I have 87771 miles on my car. I have to add a quart of oil in between oil changes. I have had to do this since I purchased the car 6/2008. The car has been leaking oil for awhile now.
Key fob quit working. I use the key to manually unlock car. However, after car is parked and off, the doors lock and unlock themselves. The front and rear lights flash while doors locking and unlocking. The other night, it was flashing morse code for over 24hours. I do not have on star connected. Horn quit working 4 months right before key fob quit. I can't use my bright lights, because I lose dash lights, head lights. My son and I share this car to drive to work. Since the lights started flashing all day and night, I felt it is unsafe for him to drive to work which is 40 miles one way. Why so many issues that are not being taken serious? I drive my car during day time. I pray I make it to work. I have to drive 9 miles one way to work. However, I drive highway 75 with semi trucks going 70 miles an hour. If this car loses power on that highway, I will probably not survive. Unsafe and not reliable vehicle. Chevy should help us monte carlo owners get them fixed. Thanks for your time.
