Once again, it was the FIRST MODEL YEAR for a new design = problems & bugs
A popular listing but remember that electrical issues, roof separation issues, and other problems have cropped up just as much if not more in subsequent years. Especially the dreaded DBS.

The 4 speed auto is well thought of especially compared to the 4 speed auto in the C5's. I've never heard that the A4 was "weaker" than the A6.

Crank pulley was a simple fix and the vast majority of 05 owners have never had any issue with the rear differential being weak.

There have been issues with every year of Corvette and any used Vette you look at should be researched including a service history printout (need the VIN) from a good GM dealership.

The 4 speed Auto in 2005's is basically the anemic 700R4. It was slightly modified but GM had it its peak power input listed at 380 Lb.Ft. of torque.

The A6 or the 6L80E is rated at 440 Lb.Ft. of torque. Quite the difference. And that rating is for a 8,000 pound truck/vehicle.

My A4 grenanded on me and my car had to be towed to the dealer. I was just driving down the highway and some internal shaft/spline just snapped. The car only had 8k miles on it.

If you put an LS3 motor in front of the A4, the A4 would die very quickly.

That's one of the reasons why the 2006 have the best record for reliability. Chevy worked HARD to debug the 2005's and the quality control on the 2006s is apparent to anyone who has driven both.

Not to hurt anyone's feelings but the 2005 4-speed automatic is a big letdown compared to the 2006 and later 6 speed automatics. And IMO the steering wheel is butt-ugly.

I've had my 2005 for five years now, brought it brand new in May 05. My only problem had been DBS. I bought an Optima Yellow and battery tender to help alleviate the problem.

Our early `05 (sept 2004) has been problem free to 28k miles . . 1 set of tires, 1 set of brakes, recall on the roof and active handling sensors.

`05's are a good value by comparison - - but each year C6 thereafter gets better and better . . .conventional wisdom suggests you should do your homework on a specific car, but buy as new as you can afford.

And here's a link to yesterday's discussion on the same topic:
http://forums.corvetteforum.com/c6-c...of-2005-a.html

Good luck-

Default My .02 cents

If you haven't already, please consider test driving a used 2008 LS3 NPP and/or a used 2006/2007 Z06.

I think you will find them to be more fun - nothing against the 2005 to be PC.

Wait, until a great deal comes along, and you will be much happier.

Not a bad rap, just first year of C6. Gives them few more problems initially. Most have all the bugs worked out of them by now.
I love mine, no issues, and won't be getting rid of it till i have to

and well put!

Just from reading the forum it's evident problems can and do happen with any model year car. My (modified) 2005 is run hard and has been ridiculously reliable and trouble free. It's been a great car in all respects.

2005 - http://www.jdpower.com/autos/Chevrol...rtible/ratings
2006 - http://www.jdpower.com/autos/Chevrol...rtible/ratings
2007 - http://www.jdpower.com/autos/Chevrol...rtible/ratings

Looks like the numbers bear this out. 2005 scored 4, 3.5, 4, and 4.5 on long-term dependability, while 2006 scored 3, 3, 2, 4. 2007 was 4, 3.5, 3.5, 5
2006's were less troublesome than '05's.
At least here on the forum where we have hundreds of owners discussing their cars at any time.

Biggest is of course that the '06's didn't have a column lock and DBS. And this issue hit many, up to 1/3 of MN6's, and with many cars more than just a few times. Not even to mention all the numbers of dead batteries of ignorance, from not leaving the tranny parked in reverse. Especially common due to a non-owner driver or technician.

Second was/is the harmonic balancer coming loose. In 2% or more of '05's up to VIN 111039.

But a few other more minor problems were just in '05's:

A/C factory freon overfill.
Squealing brake pads were much more common.
Mal-aligned doors causing rear quarter panel damage and shifter rattling in cold temps I believe are a few others.

DBS is only an '05 MN6 issue. Included in the factory BCM reflash fix was another electrical gremlin repair affecting just a few early '06's. But true DBS as originally defined here on the forum can only happen in cars with a column lock.

The crank pulley is a simple fix? The TSB is a mile long and it costs over $800 to redo properly!

Why should he test an LS3 or LS7 as he clearly stated he has an LS7 motor in his car.

I haven't had any of these issues come up at 35,500+ miles. The roof separation was a straight out recall on all 2005 but didn't have any problems with that.

2006 was the first year of the A-6 in Corvette. Were there any issues in that first year with that tranmission?

I got mine at MSRP and at the time they were asking thousands over MSRP and not budging.
Yet I sit in my 2005 and then sit in a 2009 and it does not feel any difference though we know each year there are small refinements and the change to the LS-3 in 2008. But If I were to change I would just wait for the next generation so that it isn't like the same car from the base coupe, Z-06, GS and ZR-1. Just by sitting in them they all feel the same.

I agree.It is not the fact that it is an 05 that I would be concerned with.I would be much more concerned that the car has had the crap run out of it and then put for sale.Sounds like a cobbled up POS to stay away from.
There are too many NICE cars out there to gamble on what may be someone elses problem car.
Just because it may be cheap,does not always make it a good deal.

Not according to actual owner surveys.

Never heard they had a bad rep. No problems on my 3LT at 40k. Roof replaced on recall, hardly a problem.
