On the 2006-2007 Chevrolet Monte Carlo, only the last two years of the Monte Carlo, 2006 and 2007, fall inside GM recall 14V355000. On the affected cars the ignition switch can be jarred out of the run position by the weight loaded onto the key ring - a heavy set of keys plus a fob, plus a pothole or a hard bump, is all it takes. NHTSA lists the consequence as two-sided: with the key out of run the air bags may not deploy in a crash, and the driver simultaneously loses engine power, power steering and power braking. The campaign as a whole covers 3,141,731 GM vehicles; the Monte Carlo is one of six models named in it.

Common Symptoms

  • Engine cuts out while driving
  • Ignition key knocked out of the run position by a bump
  • Sudden loss of power steering
  • Sudden loss of power brake assist

How to Fix

Chevrolet dealers do the work at no charge. The repair is not a new switch - the dealer installs two key rings and either an insert in the key slot or a cover over the key head on all ignition keys, so the keys can no longer pull the switch out of run. Until it is done, carry the ignition key with nothing else on the ring and the fob removed. Notification started September 23, 2014; check your VIN at nhtsa.gov/recalls or call Chevrolet at 1-800-222-1020 (GM recall 14299).

On the 2000-2007 Chevrolet Monte Carlo, the cable-style window regulators in 2000-2007 Monte Carlos fail when the cable stretches, frays, or binds on the reel. The window can drop into the door or become stuck partway. Both front windows are commonly affected. Replacement regulators with added cable guides are an improvement over the original design.

Common Symptoms

  • Window drops into door panel suddenly
  • Window moves unevenly or at an angle
  • Grinding or popping noise when operating window
  • Window stuck in down position
  • Motor runs but window does not move

On the 2000-2007 Chevrolet Monte Carlo, the Electronic Brake Control Module (EBCM) mounted on the ABS hydraulic unit is prone to failure due to internal solder joint cracking from vibration and thermal cycling. When it fails, ABS, traction control, and stability control all stop functioning. The brake warning light, ABS light, and traction control light all illuminate.

This issue also affects: Chevrolet Equinox, GMC Sierra 1500, Cadillac Eldorado

Common Symptoms

  • ABS light on
  • Traction control light on
  • Service stability system message
  • Loss of ABS function
  • Brake pedal pulsation during normal braking

How to Fix

The EBCM can be sent to a rebuilder for solder repair and reprogramming, which is more affordable than dealer replacement. Alternatively, replace the ABS modulator assembly. After replacement, the module must be programmed to the vehicle VIN. Bleeding the ABS system requires a scan tool to cycle the pump and valves.

Typical repair cost:$300 - $900

This issue also affects: Buick LeSabre, Buick Park Avenue, Cadillac Allante

Common Symptoms

  • Coolant leak
  • Low coolant

On the 2000-2007 Chevrolet Monte Carlo L67, the Monte Carlo SS uses the 3800 Series II Supercharged (L67) engine. The plastic coupler connecting the supercharger snout to the rotor assembly wears out, creating a loud rattling noise at idle that sounds like a broken component. Despite the alarming noise, this is a minor maintenance item unique to the supercharged models. The supercharger oil also needs periodic replacement.

Common Symptoms

  • Rattling or rock-crusher noise from supercharger at idle
  • Noise disappears under boost/acceleration
  • Reduced supercharger whine indicating worn coupler
  • Slight boost loss in advanced cases

How to Fix

Typical repair cost:$30 - $250
