Owner reports
Selected complaints filed with NHTSA by 2005 Pontiac Sunfire owners, lightly cleaned up (personal details are redacted by NHTSA).
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? …
Going down hill, turned my car to the right and the car keep going straight. It did not turn at all. I almost got hit by on coming traffic, but my car hit the curve first stopping an accident from occurring I have replace window motor twice and they have went out again now. And I have also replaced window motor buttons for a second time in the past 3 years
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. …
Speedometer failure- one day, I was driving to work on a residential road about 35 MPH and noticed that my speedometer was registering 80 MPH. This came to a great shock to me. I attempted to shut off the ignition to see if the speedometer would reset and it didn't. Also, the speedometer would not return to 0 MPH- it only dropped to about 65mph. I searched 2005 Pontiac Sunfire speedometer and 2005 Chevrolet cavalier speedometer in google and have found many blog postings on automotive websites about the same issue with an inaccurate speedometer and/or gauge cluster malfunction. This issue also seems to extend beyond the Sunfire/cavalier models to other GM vehicles back to 1993. …
Only routine driving preceded this incident. The tachometer and speedometer on my 2005 Pontiac Sunfire began to act erratic prior to 33,000 miles. At ~34,500 miles the tachometer completely failed in a position which prevented the speedometer from functioning (the speedometer needle was held down by the tachometer needle). This was a tremendous safety concern especially since my teenage daughter was driving the vehicle. This appears to be an all too common problem for several late model GM vehicles and should be considered a safety concern since it prevents the proper operation of the vehicle and can distract the driver. I can't imagine that a speedometer failure would not represent a safety defect and warrant action. I have had the instrument panel replaced at the dealer. I contacted Pontiac customer service and they appear to only log complaints. …
We have a 2005 Pontiac Sunfire with 50000 miles on it. The other day the speedometer started fluctuating erratically. It is now stuck on 50mph. After reading several forums on the internet, it is very apparent that this is a common problem with the Sunfire and cavalier vehicles. The instrument panel cluster is defective on these vehicles and it also affects the other gauges. 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. To me this is a serious safety issue. Not knowing the correct speed of the vehicle at any given time is an issue. There are several instances on car complaints.com where people have been driving causing panic when their speedometer starts jumping around. …
Speedometer was not steady during acceleration or deceleration then it just stopped at 55 to 60 MPH. Next time I drove the vehicle it did not work at all until the car got warm and all of my other gauges started having problems. My fuel gauge and temperature gauge went all the way around and just stopped and my RPM does not work at all. I took the vehicle to the dealership and they put it on the computer and said that it just needs to be reset and that I needed a new battery, after I got that fixed I took it home and 2 days later it started all over again. I took the vehicle back to the dealership and they said that it might be a gauge cluster they were not sure and that it would be $500. I could not afford it at the time so I decided not to get it fixed since they could not guarantee me that was the problem. My speedometer does work as long as it is warm outside. …
I have a 2005 Pontiac Sunfire 4 door, VIN [redacted] . I have been generally happy with the car. Starting in early December of 2010, my entire intrument panel cluster stopped working. It started with the fuel gauge showing out of the range of the gauge and then the temperature gauge started malfunctioning and reading artificially high. I brought it to scherer Chevrolet, Buick, GMC in kitchener, [redacted] where I work. I asked if there were any hidden or secret warranties on this as I didn't feel this was something that should go on a car. They said there wasn't. They did extend me a "goodwill" discount but even with that it cost me $635.55 parts and labour to replace the instrument cluster. I intend to write to GM Canada and include copies of these other reports and try and negotiate a refund as I think this repair should be covered.
All gauges in the vehicle have stopped working (I.e. Speedometer, tachometer, fuel, and temp gauges). Told that this is a known issue with Pontiac Sunfire models from years 2003-2005. Also, with the Chevrolet cavalier 2003-2005, which is basically the same car. GM changed suppliers for the instrument cluster for these years. Instrument failure is caused by the inferior parts used by GM, and it is a safety issue. One can not blame instrument failure on a lack of maintenance of the vehicle on the owner. Especially on a vehicle that travels roughly 5,000 miles a year. Such an issue is the fault of the manufacturer, and their use of sub-par materials. Have checked fuses, and had the electrical system checked (I.e. It's not a short to ground problem). These are not the result of the gauges failing. Told the cost would be over $500 for a new instrument gauge cluster. …
