You need to shut the trunk gently. If you slam it down, the latch does not have enough time to catch. My Nissan has the same problem, and my Honda does too! Push it down don't slam it! :)

I have a Pontiac Sunfire 04 with the same back closing problem. The previous poster is correct - instead of slamming the back trunk down like a BMW or a Minivan - gently set it down with a push.

I have bought a Automatic silver 2004 Sunfire 4door sedan..

I like the looks and the dash lights are easy on the eyes at night.

However there is a bad rattle and a clunk in the undercarriage. When I hit bumps.

Highway driving is nice.. drags a bit in the city.

I am taking it in to a dealer...Hopefully they can help.

Does anyone know what the rattle could be?

Hey dude, the suspension has nothing to do with the transmission, totally different part, totally different purpose! Just thought you should know!

I've had my 04' sunfire for almost a year and a half now, and I absolutley love it! Its great on gas mileage, it's compact, and it's very sharp looking compared to older Sunfires.

The only thing I'm not fond of is the color. Mine is "taupe" or sandalwood if you will. It's a very nice color, especially with the black interior, it's just not my particular taste. There is also a whistling or squeaking in the passenger side front end. Does anyone else have this problem? I have yet to go to the dealership to get it fixed.

I think that just about every Cavalier/Sunfire in production has that same whistling squeal coming out of the front end. Took my Cavalier to the dealer many times, though many of the mechanics claimed they "couldn't" hear the noise. Other than that, no complaints :D.

I have an '04 Sunfire and I just bought it. The manual was not in the car can someone please tell me how to set the clock?

30th May 2007, 20:28

I have an 04 Sunfire... purchased used with 23,000 + on it. I have had it since July of 05...I have 77,000 + on it now and the gas gauge just stopped working. Anyone else with similar problems? Easy fix?

I have the 2004 Pontiac Sunfire with the manual transmission. In all I am pretty satisfied, but does not compare to my celica that I had. I bought the car used last year with 29,000 miles on it, it now has just over 38,000 miles on it. My problem is while driving the other day, the clutch pedal went straight down to the floor board and now I cannot get the key to turn (I assume it is because of the clutch not engaged). It is hard to believe that the clutch would go out with that low of mileage, is this a defect? I bought the car thinking it would be low upkeep and cannot afford to fix it.

I have a 2004 Sunfire that I bought used just 4 months ago. It now has 53,000 kms on it. The clutch pedal went straight to the floor on mine too and we couldn't get the car to start either. What the problem with our's was that the clutch line was rubbing up against the brake line and eventually wore through the line so the fluid leaked out. We had to replace the hose. The mechanic said the clutch line was routed badly. Has anyone else had this problem?

My daughter has a 2005 Pontiac Sunfire we have had the truck in 3 times for repair.

Does anyone else have this problem???

I have a 2004 with a manual transmission and tonight the clutch pedal went straight to the floor just as 2 previous posters noted.

This review came up on a google search for clutch problems so I don't know what went wrong yet since no mechanics are open at this hour.

10th Jul 2008, 10:17

I also have a manual 2004 Sunfire and I have had trunk problems from the get go, along with the passenger seat always sticking. Just the other day my clutch pedal went straight to the floor (I have 100000km on mine). I was also told it was because the hose was badly positioned and it was rubbing until it worn a hole in it. Now I am faced with trying to find a hose that doesn't cost a fortune (only from the dealer and $280 Cdn.) Any suggestions?

Here's the solution to all your 2004 trunk closing problems:

Spray generously some WD-40 or similar lubricant on all moving parts in the trunk latch mechanism. Then, with a crowbar or similar strong piece of metal, gently pry the metal hook that the latch closes around up and back (towards you). The latch is getting stuck and when you close the trunk it's pushing the hook that it latches to down. The harder and more often you close it, the more you're bending the hook so that it eventually will never catch. An easy fix for under $10 that literally ANYONE can do them self. My mechanic did it for me for free and explained the whole problem. Good luck.

Own a 2004 Sunfire Si 2 door coupe. Just developed a beep on my passenger side rear tail light. Some one explain to me, if this bulb is about to burn out, or do I have a bigger problem? The beeping happens when I lay on the brake and signal right. Someone help me out here.

27th Oct 2008, 23:21

I bought my 2004 Pontiac Sunfire SE used in July 2006 with only 31,000 miles. Only problem I had out of mine until recently was sometimes it acted as though it didn't want to start. Otherwise over the course of the past few months, when going into OD, the transmission shifts very rough. Any suggestions? Maybe someone with the same problem?

3rd Nov 2008, 01:46

I have a 2004 Sunfire CP, and sometimes I'm driving and stop, and sometimes don't stop - I push the gas and it seems like it won't go ,but then I notice the car shuts off... I think it does it more when I have my air conditioner on... Does anyone have this problem?

24th Mar 2010, 16:13

I purchased a 2004 Sunfire with 80, now has 135, driving a lot of highway miles. Very stable car, good gas mileage sporty look.

Just got my first problem. Squeaking in the front end when you turn slowly? Plenty of fluid? Besides that good car. I'm going to get my brakes replaced this Thursday and have the mechanic hear the noise???

18th Jun 2010, 11:54

I also had the same clutch problem. I replaced the whole clutch when that went, and then I had to replace the hose. Now I have to replace the engine, because it sounds like a lawnmower engine. This problem happened after I had gotten an oil change. Apparently, this is also a common problem with the Sunfire engine.

23rd Feb 2011, 21:02

To the previous poster; that is not a common occurrence to have the Sunfire engine sound like a lawn mower. I have not ever heard of this before, and I'm a certified GM mechanic with 12 certifications and one ASE master degree.

The only reason it would sound like a lawnmower after a oil change, is due to the mechanic you had change the oil, didn't put oil back in the engine, did not put enough oil in the engine, or put in the wrong viscosity of oil. All Sunfires are recommended by GM to use 5w30 motor oil. The 02-05 is recommended to use 5w30 part or full synthetic, and 2001 and pre models are recommended to use 5w30 conventional (original type) motor oil (non synthetic).

24th Feb 2011, 17:57

Just want to clear one thing up. I posted on Feb.23 at 21:02 and I have 7 NOT 12 certification's. I have 7 GM certified certifications and one ASE master's in automotive technology. I'm not sure how it is showing I have 12 certificates on my previous post. I thought I should make it clear I have 7 not 12 certificates, and one ASE masters in automotive technology.

25th Jun 2011, 19:33

I had the same problem with mine; it quit working at about 100,000 miles. The most likely cause when these go out is the sending unit in your fuel tank. Have had this problem in a few of my rigs, and the majority of the time it's that, but sometimes it's faulty wiring and even a bad gauge cluster. Cars have problems, and people have issues.

19th May 2012, 23:18

My 2004 Sunfire clutch has no pressure. There was no fluid in the master cylinder. Filled it up and pushed the clutch down several times till the pressure started, then it was OK for a while. Started a few hours later, and no pressure and fluid was still in the master cylinder. Would there be air in the line, or a leak? Need to bleed the line, and where do I find the bleeder valve? Is there a sensor that should be changed, wherever that is?

Thank you.

Best solution ever, thank you so much!
