2006 Chevrolet Colorado Owner Comments

problem #9

Aug 182011


  • 20,000 miles


GM passlock system in my 2006 Chevy Colorado fails daily leaving me stranded for 10-15 minutes until it resets itself. If engine stalls in a turn lane, it creates a hazardous situation.

Colorado 4-cyl

  • 67,000 miles
2006 Chevy Colorado 4 cyl. 2.3L camshaft position actuator went bad at 68,000 miles causing rough idle, some stalling, and loss of power. Originally changed camshaft solenoid due to missing screen. Problem came back immediately, dealer tore apart engine and said the actual camshaft actuator needed replaced. Cost $1200. Truck was bought brand new, and serviced on schedule. Have been told this is a common problem for the Colorados, and must be because there is even a technical service bulletin about it. GM refuses to pay for it unless still under bumper to bumper warranty, which for my year expires at 36,000 miles or 3 years. At 67,000 miles, parts in the engine should not be tearing up. It is poor quality and dangerous to be driving.

Check engine light has come on due to several misfires. Got this checked out at the dealership and they said this was a common issue with this model vehicle and that I needed to replace the cylinder head as the manufacturer created a faulty seal for these engines and they tend to leak at idle. This fix was quoted at 3000 dollars. I checked around and found a bulletin released by Chevrolet stating how they knew about the issue and basically saying how to fix it. Basically Chevrolet owns up to this being their mistake but is unwilling to help out the vehicle owners. They want us to pay 3000 to fix a vehicle that is suffering from their mistake. Chevrolet should be willing to count their losses and help out owners with this issue.

A 2006 Chevy Colorado was having misfires prior to September 2010. This caused the check engine light to come on and so I took it to a Chevy dealership for a diagnosis. The diagnosis is the same for thousands of Chevy Colorado engines as they need new seals, bolts, and a new head. My service manager said this has been a major issue with this engine since the introduction of this vehicle and it is due to a mechanical flaw and not wear and tear. These engines have put a major burden on General Motors/Chevrolet customers as they have to spend large amounts of money to correct a mechanical flaw noticed by many certified mechanics. Please take this information into consideration as I have done extensive research in finding that this is not an isolated problem and numerous customers have been failed by this such company.

Check engine light came on intermittently. Engine heated up and transmission would not shift into overdrive on freeway. Transmission shifts hard now and then. Checked website for any recalls on engine, took to dealership, still under warranty. They keep the truck for 2 weeks, did machine work on cylinder head, computer said all cylinders mis-firing. Print out from Chevrolet said 'head replacement', which was not done. Notified GMC customer service and opened file. Back to dealership second time for drop in idle and misfire during driving. Could not find anything wrong. Dealership said to bring back if said condition gets worse.

Colorado 4WD 5-cyl

  • Automatic transmission
  • 45,000 miles
Vehicle experiences engine miss fire code that causes check engine light to come on. Symptoms started at 45,000 miles. Dealer reset computer first time with no repairs needed. Computer showed multiple miss fires the second time. Dealer stated this is common with high mileage Colorados due to carbon build up on valves. Dealer did check to ensure there was not a bad coil. Suggested using lucas fuel treatment. Did help rough idle and power. I was told next step will be to replace the head.

Colorado 4WD 5-cyl

  • Manual transmission
  • 30,000 miles


Engine loses power over 55mph and misfires on cylinder one. Engine light comes on. Dealer refuses to fix after looking at it and saying nothing has completely failed yet. They are waiting for me to be stranded on the side of the road I guess.

: the contact stated while driving the engine revs at all speeds. The vehicle has been to the dealership twice for repairs to the engine. They replaced the accelerator pedal and throttle body, but the problem still exists. Additionally, the passenger side airbag light illuminated. Although the dealer was alerted no appointment for inspection was made.

I have a 2006 Colorado 2006 crew cab L-5 engine. I have owned it for 2 1/2 months. It has been to the dealer for 1. rear main bearing seal leak three times. 2. two wheel alignments. 3. auto- transmission cable fell off. This was when I was bringing it in to the dealer for one of the many repairs. 4. it still has to go back for replacing the rear window (on order). This vehicle has been in the shop for 25% of the time I have owned it.
