C5 Problems/Reliability
Are there any common Problems with C5 Corvettes, or even specific years of them? I've been looking at some and most seem to be in good shape, but I was wondering if there was anything special to really look out for with them. Or if anything in particular generally goes out once they're above 100k, or if it's just hit and miss... Thanks for any input on the subject.

black 2000 coupe here w 85,000mi on it and ZERO real issues so far w it.. knock on wood..
|
2002 coupe - 72,000 miles just ABS ($150 absfixer) dim/dark HVAC display and Techron for my gas gauge; other than that just regular maintenance (Money spent on mods doesn't count. :) ) Oh I forgot, I think the original owner had the leaky diff seal fixed under warranty.

My rear tires wear too fast !!:rofl::eek:
|
My 04 had its water pump replaced before I bought it at 28k.
Recently it had lifter problems and they were fixed. I'm at nearly 60k now. aside from that... tie rod end... headlight gear. eh. |
Sticky, Sticky, Sticky........top of the page (weights, measurements, etc.) Take a look.

As a Corvette breed the C5 is much improved over the previous generations. However, they are still (as a breed) riddled with problems. Don't get me wrong, it is completely worth it to drive these cars everyday. Here are some things you may eventually "learn" about the C5:
1. Electrical grounding issues wreak havoc with ...fill in the blank. 2. Sensors/modules that go bad; Steering wheel position sensor, Oil pressure switch, hazzard light switch, turn signal stalk, ignition switch, ABS/AH/TC module to name a few 3. Mechanical failures include headlight gears, valve springs, leaky butt, rocking seats 4. Driving carefully to be sure not to scrape the nose or rockers on speedbumps or driveways etc These are all common but may not happen to every car. The good news is that there are already inexpensive fixes for most things like this that you can do yourself if you are comfortable around tools and cars. I wouldn't let any of this stuff deter you from a purchase unless you can't do any work yourself. In that case you'll need some deep pockets every now and then to keep her on the road. |
There are lots of things that could go wrong. :lol:

Owning a C5 is fantastic. I"ve had 8 Vettes before this and this is really the best (2004 Vert.)
The major prolem which occurs everyday during the Spring and summer to every Vette owner, is the addiction to buying mods!!! Take care of it...it will take care of you! Jeff |
2002 EB Coupe, purchased at 11k miles now at 16k.
Passenger headlight gear Headlight switch wouldn't enable running/gauge lights Bad ignition coil cylinder 7 Low oil level sensor Ripped driver side door actuator will lock but not unlock vehicle RDCM flakey, doesn't always do what I tell it to do EBCM fixed at ABSfixers (usual symptoms, no tcs/abs/ah) Yup, that's about it for now. |

I just bought a 98 Vette with 100,000. One of the things that bothers me is that I can't check the trans fluid. I don't know whether I should change it, or leave it. I've heard if the fluid has been changed on a regular basis, that it is good to keep changing it. However, if it hasn't been changed, and then you do change it, the new fluid can "clean" the trans and create problems. Thoughts?

common problems discussed often here
leaky butt-differential seals going and leaking fluid headlight motors Column lock EBCM bushing in seats going out causing the seat to rock window seals synchros bending oem batteries dripping acid onto the wiring underneath window controls stop working complete PITA clutch install. |
The C5 was designed to go 300,000. Your mileage may vary
|
None of the above mentioned problems are not what we see every day of the week across five car lines.Nothing unusual here at all.

Many comments above summarize the common issues well. Here is my list
(My car is a 2002 with 60K on the clock) 1) Fuel sending unit assemblies going out resulting in busted gas gauge 2) Leaky butt - and 4 years after fix, problem has resurfaced 3) Headlight gear gone out 4) Door control module problem resulting in inability to lock door 5) HVAC actuator going out resulting in blasting heat on driver side and ice cold blowing on passenger side 6) Bent Synchros -- this one is the worst because I am not looking getting a rebuilt transmission 7) But of course, we must not forget the dreaded column lock! Comments: 1) Many will tell you on the forum that Seafoam or Techron concentrate resolves the gas gauge problem. Not true in my case, I had dealer replace my fuel sending units and gas gauges work great now (and ONLY Chevron gas put in the tank ever since). 2) Most items above were small and thanks to this AWESOME forum, I fixed the issues myself 3) The synchro problem does suck... I am looking to have my tranny rebuilt. I do have a FI car so that probably accelerated the loss of life 4) I found out from the Forum, that C6 shaft seals are better than C5 shaft seals. I will try them on the next go around for the leaky butt problem. Despite all these issues, do I still love my C5Z? Absolutely :rock: |

The link Jackalope provided is a good one.
I also think the harmonic balancer should be mentioned. It frequently wobbles and/or separates. I didn't see it mentioned in this thread or the one Jackalope provided the link to (although I only looked at the first 6 pages). |
