The 1991 Mitsubishi 3000GT has no open NHTSA recalls. Owners report 4 recurring issue clusters, led by “Transfer case leakage and wheel lock-up.” Mitsubishi publishes short, conservative intervals: oil every 7,500 miles normal / 3,750 severe, and — unlike many rivals — an explicit CVT fluid replacement schedule rather than a 'lifetime fill' claim. Read the severe-service column honestly: stop-and-go city trips, short hops, and hot climates all qualify, and they describe how most Mirages actually live. The 10-year/100,000-mile powertrain warranty stays intact only with documented on-schedule service.
No open recalls on file. NHTSA lists no unrepaired safety recalls for this year, make and model. A recall can be issued at any time, and a specific car can still have one open — check yours by VIN at nhtsa.gov/recalls.

Critical for safety and preventing major damage
Replace every 7,500 miles normal / 3,750 severe. Mirage's 1.2L three-cylinder holds barely over 3 quarts — small sumps punish stretched intervals. 0W-20 on most recent models.
Estimated cost — typical U.S. ranges
Dealer
~$120–$160
Shop
~$85–$115
DIY
~$25–$55
Full synthetic costs more than conventional. 5-quart 0W-20 + filter is the typical bill.
Mitsubishi schedules CVT fluid replacement — commonly every 60,000 miles normal / 30,000 severe (check your year's table). Use only the specified CVT fluid (J4/CVTF-J4 family); generic ATF destroys the belt-and-pulley unit.
Estimated cost — typical U.S. ranges
Dealer
~$360–$500
Shop
~$255–$355
DIY
~$80–$180
CVT fluid is manufacturer-specific and pricey — do NOT substitute conventional ATF.
Rotate with every oil change. Light Mirages are easy on tires but the economy-focused OEM rubber wears fast when neglected.
Estimated cost — typical U.S. ranges
Dealer
~$85
Shop
~$60
DIY
Free
Often free at the shop where you bought the tires — worth asking before paying.
Inspect pads, rotors/drums, and lines at each service — Mirage G4 retains rear drums, which need periodic adjustment checks.
Estimated cost — typical U.S. ranges
Dealer
~$85
Shop
~$60
DIY
Free
Most shops do this free as a courtesy with any service. Don't pay separately if you can avoid it.
Replace every 2-3 years per the schedule. Cheap job, big ABS-unit insurance.
Estimated cost — typical U.S. ranges
Dealer
~$180–$200
Shop
~$125–$140
DIY
~$10–$25
DOT 3 or 4 — match the cap. Vacuum bleeders make this a one-person DIY.
Keeps your vehicle running smoothly and efficiently
Iridium plugs commonly every 60,000 miles on the Mirage's 3A92 and Lancer's 4B11 — verify your year's table, as some engines list up to 105,000.
Estimated cost — typical U.S. ranges
Dealer
~$285–$390
Shop
~$200–$275
DIY
~$25–$100
Iridium plugs cost more but last 100k+ miles. V6/V8 access varies wildly — some are tough.
Mitsubishi's schedule replaces the engine air filter every 15,000 miles — shorter than most brands, and a 5-minute DIY on the Mirage.
Estimated cost — typical U.S. ranges
Dealer
~$60–$95
Shop
~$45–$70
DIY
~$15–$40
5-minute job on most cars; the airbox lid usually has clips, no tools needed.
Inspect from 60,000 miles and replace on cracking. The Mirage's single serpentine belt also drives the A/C — a failure strands the car's accessories at once.
Estimated cost — typical U.S. ranges
Dealer
~$195–$235
Shop
~$135–$165
DIY
~$20–$50
DIY-friendly if you can reach the tensioner. Inspect for cracks rather than swap on a strict mileage interval.
Extends the life of your vehicle and improves comfort
Replace every 15,000 miles, behind the glovebox. Often skipped at quick-lube visits — worth checking if airflow feels weak.
Estimated cost — typical U.S. ranges
Dealer
~$60–$95
Shop
~$45–$70
DIY
~$15–$40
Usually behind the glovebox. Shops charge labor for a 10-minute job — easy DIY win.
First change around 60,000 miles, then roughly every 30,000-45,000 per the schedule. Mitsubishi long-life coolant or equivalent OAT for your year.
Estimated cost — typical U.S. ranges
Dealer
~$285–$330
Shop
~$200–$235
DIY
~$25–$60
Use the manufacturer-specified coolant — wrong color/chemistry can damage the cooling system.
Test annually after year 3. Small-battery economy cars have little reserve — the first cold snap finds a weak one.
Estimated cost — typical U.S. ranges
Dealer
~$225–$390
Shop
~$160–$280
DIY
~$130–$250
Most auto-parts stores test and install batteries free with purchase. Skip the dealer markup.
Typical U.S. ranges. Actual quotes vary by shop, parts choice, and vehicle condition.
How we estimate: Dealer = OEM parts × 1.4 + labor × $165/hr. Shop = parts + labor × $115/hr. DIY = parts only.
