Although the SN95 generation of Mustang was generally good, like all vehicles there are some problems.

This thread will cover some of the common problems with 1994 -2004 Mustangs (SN95). The information in this thread was provided by members of our community, thank you all that helped.


If you are looking for problems with particular engines, there is a link to each below:
4.6L V8 4V Problems
4.6L V8 2V Problems
5.0L V8 Problems
3.8L V6 Problems


When looking for a SN95 Mustang look for signs that may be the source of problems down the road. Like all vehicles the main factors of problems are from abuse, age or high miles/kilometers and lack of or improper maintenance. The SN95 generation is starting to roll into 20 years, so many of these common issues are from age or high miles/kilometers.

Lastly, if you have any corrections or addition information please make a post below. I will update this post with addition information.




1. Crystal White paint peeling, highly likely to happen.
Solution: Extreme care, but likely repainting.
Cpotts13, MustangChris

2.Quad Shocks rubbing. Caused by changes to suspension such as lowering (more than 1.75”?) or large rear tires.
Solution: Flipping or removing quad shocks
Ferocious

3. E- Brake cable rubbing driveshaft and like to rust
Can be caused from worn rear control arm bushing
Cpotts13, greenscobie86

4. Inside fan only blows out defroster vents
Usually caused from broken vacuum line along firewall.
Cpotts13, Twista

5. Throw Out Bearing (TOB).
Solution: Replace, preferably with an upgraded one.
Orange94, Slykin

6. Aftermarket short throw shifter stoppers pushing out of gear.
Solution: Adjust stoppers to correct position and tighten.

7. Lose ground or blown rear amp on radio, specifically the Mach 460 system

8. Odometer gear breaking
Solution: can try a upgraded aftermarket one, but its commonly just replaced.
lutter94, Orange94

9. Clutch Cable
Solution: Replace with a stock cable (maximum motorsports offers a good stock one). DO NOT GET AN AFTERMARKET CABLE! The majority of them are garbage and will cause problems. Can use an aftermarket adjuster with stock cable with no problems.

10. Door seals, will need to be replaced eventually

11. Power seats, motor and shaft like to break.
Solution: Fix or replace. Or switch to manual rack.

12. Trunk lock

13. Bad Window Motors

14. Gas tank filler tube grommet

15. Third brake light haze

16. Leaky coolant expansion tanks
MustangChris

17. Door handles pulling off
MustangChris

18. Interior door cups get pulled off
MustangChris

19. Radiator change in 1996, different than 94/95 and 97/98
MustangChris

20. Hood recall
MustangChris

21. A/C condenser recall
MustangChris

22. Heater or A/C only works on 1 setting
Solution: Replace blower resistor
Twista

23. Gauges not very accurate. The gauges are only able to give an “okay” or “bad” reading.
So don’t be alarmed if temperature is high on the “NORMAL”, anywhere in the normal range is okay. Use your own judgement if car is overheating or not.

24. Front ball joints/inner/outer tie rods will need replacing
justinschmidt1

25. Starter solenoid corrodes

26. Alternators go bad
justinschmidt1

27. AC switch fails
justinschmidt1

28. Auto Trans, good idea to change fluid 30-40k and add trans cooler
justinschmidt1

29. Rubber Bushings, will need to be replaced eventually.

28. Replace air blower unit when the unit starts to squeak.

29. The Stalk on the steering wheel eventually fails

30. Keep a close eye on your OEM steel brake lines

31. Rear Main Seal will likely need to be replaced

32. High pressure line on power steering pump leaks, O ring goes bad.

Definitely glad mine didn't have any of those issues when I bought it, not a single one. But we won't talk about my current issues....

I'll definitely vouch for the clutch cable btw. I had an SR after my stock one wore out (old age). It snapped within a week, literally. Bought an MM to replace it and got a lighter clutch pedal and has lasted ever since. So I totally agree do NOT buy anything other than MM for clutch cable, MM is an OEM replacement

MC I'd like to know about that A/C recall.....

Great info in this thread, good job Richard!

Headlights are usually fogged over on these cars, and will either need sanding or replaced

Reverse grinds going in (manual only), usually helps going into 1st then reverse or 5th then reverse

Common for spark plugs to back out of the heads, you'll hear what sounds like an exhaust leak coming from under the hood, re tighten all spark plugs

Blower motor resistor takes all of 5 mins to replace. $20-30 part. Held in by 2 (if I remember) 7mm bolts and hooked up to a small wiring harness. Look under the glove box and to the right, it's really obvious where it is. I recommend a 1/4" ratchet with a 3" extension to make life easy. Don't go nuts torquing it down, either, it's plastic on plastic.

I added more detail about the self-changing 4.6 plugs in the 4.6 thread. (96-04, all versions of 4.6, 2V and 4V)

Power seats be sure to check fuse first. Sounds silly but always start simple. My '97 was inop until I changed the fuse, never another problem.

Hazy CHMSL an issue on 99-04 cars. 94-98 I've never known it to be a big deal.

Rear main, I think is more of a 5.0 issue. Rare to hear about it with a 4.6.

Also for the 4R70W guys, some things you really should know about (Most of this info from the guy who designed the trans originally)

Can I suggest that problems specific to certain years be labeled as such?

For example broken odometer gear = 94-98 only, 99+ have electronic odometer.

Just to help people who may stumble here on a google search. Valuable stuff for them, more traffic for us, new members and new knowledge.

One to maybe add. Stock flexible lines from hard lines to fuel rail. I read a pretty big write up on another forum about a lot of 94-5 owners having the inner liner go bad after being so old. They had solutions anywhere from stai less steel braided and AN connectors to making new rubber lines with a liner in them. It was on corral I saw it. But there were quite a few who had actually burnt..

Most of this is straight up maintenance or stuff you'll see broken when you go to buy the car.
