C5 reliability
"Hi everyone, I got a black 93 6spd coupe. 140000 on the clock. 4 problems. 1. The AC was just converted to the new freon (R-something) and recharged. I am able to adjust the climate and the fan speed. A dye was used in the system when I had it recharged a few months back, and after 2000 miles, I took it back and it showed no signs of leaking. The problem is that it doesn't seem to get as cold as the setting shows (60 degrees), and when I turn the fan speed down, the air blowing from the vents seems to get warmer as well. I have an 03 ford ranger, and when I have it set to 60, I can turn the fan speed up and down, and the air is always cold, just doesn't blow as hard on lower fan setting (as expected). Any ideas? Problem 2: idle is erratic upon first start. If i start the car and drive it, it idles at 1100-1500 at stop signs. However, if I shut the car off and restart, it idles perfectly at 700rpms at stop lights. Weird huh? Problem 3: this just happened a few days ago... I noticed a puddle of coolant under the front passenger bumper after a long drive (car never overheated though). The car normally runs between 210 and 220 degrees, I can let it idle for hours and it never goes past 220 with the ac running. It appears that the coolant spilled out of the plastic overflow tank at the cap. Any ideas?
Problem 4
The led display on the dash is very dim. I can barely read it at night when the headlights are on. I do have an aftermarket stereo, and I'm sure that's the cause of the dimness and the sys warning light. U guys helped me a bunch in the past, and I really appreciate it. Anymore ideas on these probs are greatly appreciated. Ryan "
And this -
"Here's a little history. Car sat for yrs... Started it one day and it ran for abt a week...."
And how about this -
"I recently installed a new stereo system, will run the codes again. But I never got 72 before. Is there anyway to clear the light with this new stereo? I just noticed that the dash seems a little dim, would that set the sys light off too? Thanks again for all your help. "
So Ryan bought a '93 that sat for number of years with 140k on the clock, a crappy AC freon conversion, problems with the anti-theft system and he installed a stereo system himself after which he notices the dash lighting is dimmed. From this he expected immediate reliability and no repair costs? MavSAk, "retarded" is not a strong enough word for this baloney. "Moronic" comes to mind.

And then he starts posting about about C4s having crappy reliability arguing initially that they are all unreliable. When that fizzles out because he has no takers, he changes his tune. Now he moves on to shoddy build, comparisons to Mercedes and Lexus, etc. Find a '93 Mercedes or Lexus that has sat for years with 140K on the odometer and crappy maintenance - see how reliable that is for 'ya Ryan.

I also looked - where's your C5 thread you were supposed to have posted? I see you live in Hawaii. Maybe it's time to give up and just go to the beach.
BTW of all the OLD cars I have ever owned My C4s have been the more reliable. First place goes to my 81 Chevy C10.
My current C4, an '87 coupe, is my dedicated autocross and HPDE car. The car has been beaten on now for 6 years and again, never once have I had a mechanical problem with this car. I go thru brakes parts, tires, and I'm always looking for ways to improve it, but the car starts every time, it goes, it stops, it turns and is fun to drive.
Sure, you read in in the C4 sections of the Forum about people having problems. Happens in Mustang forums (probably more frequently...
) Dodge forums, Yugo forums, and just about any car forum. But the percentage of people reporting problems with their cars is extremely small compared to those owners that don't have problems.It could be that you maybe didn't check out the mechanical condition of your C4's carefully before you bought them. Maybe a prior owner used cheap replacement parts. And maybe it was just time for something to cause a problem. There are C4 owners here with 200K + miles on their cars and they run fine. It really isn't fair (or right) to blame the car and the engineering behind it for a few bad ones.

Consumer Reports is my go-to source on car reliability. This aggregated data is much more meaningful than message board anecdotes (as entertaining as they may be).
I haven't seen their data on the C4, but they show the C5s as being generally of average reliability. The '04 for some reason they report as being much better than average.
. Every now and then there is a poster that starts an account, gets involved in a few threads and discussions and seems to really own a 'vette. Then he starts a thread that puts down 'vettes in some way and it quickly goes down from there. He had gone by many names. Last time he went by the screen name "12inches" now "Ryan40". He has been around for a while and seems to enjoy it. He makes little mistakes that trip him up - one thread the '93 has 140k and this thread around 100k. One thread it sat for years, this thread no mention of that. One thread he installed a stereo that he admits may have damaged his digital display and no mention of his mess-up here.

The internal combustion engine in and of itself is an engineering marvel. The fact that one of these, any of these runs for five minutes is purely amazing when you think about what actually happens in the motor and the precision necessary for this to happen. Every rotation of the crank is flirtatious dance with disaster.
Now, let's throw in the computerized management systems, and let all of these components age for twenty years. Yeah, there might be a few issues that pop up here and there. lol
But anyway, good luck with the Accord. I think a car with a warranty was a good call on your part.
At least we have plenty of vendors supporting the car and it's a hobby for me so I don't mind. It's always going to need some sort of attention just because of the age. Major systems are good on mine so nothing I can't handle.
