Have 07 HHR LT2 with 2.4l engine and check engine light keeps coming on. Dealer says must use 91+ gas and will harm engine if I don't, but manual says will run on 87 octane with reduced performance but doesn't indicate problems. Anyone else having problems with 2.4L engine and 87 octane?

Have 07 HHR and have used 87 octane gas since I bought it in 07. But I recently have had a problem with the check engine light coming on.....I swear the car knows when it is going to the mechanic because the light always goes off when I am on my way to the dealership. Have had 2 recalls so far on this vehicle and haven't been in to have either fixed.....one is replacement of the entire head area and will take an entire day and the other is something to do with the dash storage compartment. Neither have anything to do with running the vehicle so it can wait. Has anyone else had the same problems with the check engine light or a drip from the passenger dash when it rains?????

I have 2006 HHR, we purchased last August. Recently the check engine light came on, I've had it checked by 3 places, the only thing they could find wrong was the Cam Shaft sensor, I ordered the part, the light went out, 2 weeks later it came on again, had the part put on, now I've driven it about 50 miles, and the light is on again?..... When the light comes on: it shifts rough, gas mileage goes from 27 to 24, HELP, I love the car...I just want to fix it?

I am having the same on/off problem with the check engine light with a 2008 HHR. I have read it may have something to do with the emissions system and a worn or loose gas cap. I have not taken it in to be checked. No other problems.

Light comes on in the morning at about the same place every other day, about 3 1/2 miles from the house. Computer says "random misfire" but no solution is offered other than start changing out the computer components. After 7 or 8 starts it goes away and doesn't come on until the next morning at about the same place down the road. Frustrating to say the least.

Just bought a 2006 HHR...love it. Today, the 'little engine' light came on. Checked the gas cap. It runs great! Checked the manual and it mentions wet electrical from a puddle. Well, it is raining and I did drive on a highway through a puddle.
Anyone else?
Thanks

I own a 2006 HHR and last night the little engine light came on for the 1st time. I checked the gas cap and it seemed like it wasn't on right (I had just gotten gas the night before) so I fixed it but the light is still on today and I drove 35 miles to work. I have noticed that it does shift a little harder and I am using more gas just like Paula from Louisiana. Were there any fixes to any of the cars above or is everyone just dealing with it?

Did you find out what the problem was or did they fix it? I am having the same problem.

I have a 2006 chev hhr. Our check engine light
came on & auto zone ran a test & it said #3 cylinder
was misfiring. After driving the car for about
200 miles, the check engine light went off.
As long as the light is off, I am not taking it to the dealership. Any comments or suggestions.
p.s. We love our HHR! It's our baby!

Wondering if you got this figured out. We have 2008 HHR and noticed this evening the engine light is on. Checked the gas cap. Put gas in it and added dry gas. It has been damp/wet out. But we don't drive it much...have had it since Nov 2009 bought used from a dealership / it had one previous owner.

I purchased my 2006 HHR in Jan of this year. My check engine light comes on and when I took it to get it looked at the cose was that I needed a new Camshaft censor. I really think there should have been a recall regarding this issue what do you think.

Have a 2007 HHR and have taken in back to the dealer twice for the check engine light. They had said it was the purge valve, spent the money and had it replaced. Now, the engine light is back on 5 months after being fixed. Had my mechanic airblast the purge valve, he said that it was dusty, but the light hasnt gone out. Love the car, but the issues with it, and the recalls (2) are getting to be a bit much for a car!! They should recall for this light issue, seems to be common.

TRY CHEVERON TETRON FUEL CLEANER IT WORKS, ALSO THE WIRES TO THE PLUG USE DIELECTRIC GREASE AT THE PLUG - IT WILL STOP MOISTURE. I COATED THE WIRES WITHN WIRE DRY IT STOPPED THE PROBLEMS. THE ONLY PROBLEM I HAVE IS THE KEY OUT ISSUE.

I have been having the same problem with my 2006 HHR, "Check engine Light", had the car checked and was told it was the emissions misfire. Mechanic cleared the light but after a few days it came back on. My sister has the same vehicle, 2006 HHR, that she purchased in November 2005 and her light has been on since 2007 and has had it checked out several times and given different information every time. My question to you all; Does the light ever stay off? Does anyone have a solution?

I also have a 2006 chevy hhr that I bought in nov. 2005 and i just put 113000 miles and my check engine light just came on . I had 2 burned out fuses. light went out and came back on the next day so I had a code check ran and they said it was catalytic converter and spark plug wires but my mechanic swears it is neither. catalytic converter is 401.99 and they said i also needed ignition coil for 117.09 and the wires are 6.99 each plug. The only problem over time I have ever had was gear shift lever locking up and that cost 300.00 at dealership.

How come there hasn't been a class action lawsuit (TOYOTA) for this vehicle. Just aquired an 06 HHr, check engine light came on, serviced and replaced plugs. You guessed it, check engine light came back on. Found several other post that state that CHECY does not know what is causing problem. Bringing back to shop tomorrow, this time I will tell them what needs to be done.

Getting ready to drop our 2007 HHR off at the stealership this morning. The light randomly keeps going on and off...I pulled the code and you guessed it....misfire.

Kinda pisses me off because we bought the car new and it only has 50,000 miles now. We also had to have the drivers front rotor assembly replaced under warranty about a month ago...about the time the light started coming on.

I also forgot to mention that when we first bought the car we took it to the dealership for the free oil change after the break in period and they forgot to put the oil back in it! Wife started to leave the parking lot and the car started dinging so she drove it back up.

Sure enough the oil was still sitting on the table next to the lift where the car was...caps still sealed tight. All they did was a "oil drain" and not a oil change...we were pissed about that.

I hope whatever is wrong is covered under the 100,000 warranty...there is no reason why we should be out of pocket for a car with only 50,000 miles.

I don't trust dealerships...but what can ya do?
