None of the gauges work properly Gm has not issued a recall despite the numerous complaints and it is a 500 to 800 dollar repair bill to replace the instrument cluster. 2005 Sunfire and the instrument cluster is malfunctioning. The gas gauge has stopped working altogether and the temp and rpm gauge work erratically. This is definitely a recall issue and has nothing to do with the maintenance of the vehicle. Gm wants me to have a dealer check the vehicle when they are well aware of this issue as there are multiple posting from owners of this issue online.
Instrument gauge (speedometer) went first then slowly progressed into all of them. They are sporadically accurate, but most of the time rest at the low or high end and often off into the next gauge. I paid Firestone a few years back to do a diagnostic hoping one gauge was faulty causing the rest to fail, but its the cluster. Cost for replacement ~ $800. (for me about 3 weeks pay) so recently I decided I cant take it anymore and went searching for alternative prices and look what I find, a billion Sunfire owners with the same problem. (okay but a lot) and these are just the people that have bothered to complain. Been dealing with this for years, its now at the point I described above. I have emissions at the end of March. So looks like I'm out 1 weeks pay (earning a bit more, but not much) because GM wont own up to their cheaply manufactured parts. Buy American? …
Engine & cooling
Date: 5/2/07 Sunfire 2005 was purchased brand new in 9/05 investment purpose in a new car for safety, reliability, gas mileage, non-repair and price of vehicle. At 26,000 miles, $900 of repairs were placed on the car in upgrades to keep the vehicle running, to-date, counting 10 failures, first date of failure requiring car repair 12/27/06. (not including vehicle maintenance) repairs demand at a minimum 3hrs of time at each repair visit. Repairs on vehicle demand just a few more hundred dollars in cash payments and cost of a car rental while vehicle is down. Incidences of failure on vehicle remain unresolved due to Pontiac's denial and refusal to fix the vehicle. Supportive documents will show price gouging, harassment and a defective vehicle. …
The electrical system goes out and the car will not start, the horn will not work the care claim to run hot when that isn't the case. The window stop working, the engine say that it need checking however when I take it to be service they always says this model has a lot of electrical problems. I have had wires replaced, new starter, new alternator, new motor in the left window. And I have had all this done to fine out that there is electrical issue with this model. I have wasted hundreds when all you had to do is admit there was an issue and submit a recall.

I purchased my 2005 Pontiac Sunfire in September of 2005. I bought an extended warranty which expired at 75000 miles. My speedometer goes down to zero when driving. The speedometer will start working again after the car sits for a few hours; however, now the speedometer will not work at all if the car has been sitting outside in the heat. It is very dangerous to be driving and not know what speed you are going. For the last three days after working all day, I go out and start my car and the speedometer is stuck below zero so I have to drive home on the freeway not knowing what speed I am driving. This is a huge safety concern and GM should be made to fix this problem. After researching on the internet I have found out that this problem has been going on for several years. I traded in a foreign car to buy my Sunfire and now I am regretting that decision. …
