The 1991 Geo Prizm carries 2 open NHTSA recalls — most recently covering suspension and lugs/nuts/bolts/studs. Owners report 5 recurring issue clusters, led by “Interior door handle breakage.” Geo was GM's badge for imported partner cars, and it disappeared after 1997 when the models moved to the Chevrolet name. The most useful thing an owner can know is which car they actually have. The Metro is a Suzuki Swift, the Tracker is a Suzuki Sidekick, the Storm is an Isuzu Impulse, and the Prizm is a Toyota Corolla built alongside real Corollas at the NUMMI plant in California. Ask a parts counter for the donor vehicle and the price often drops and the availability improves. These are small, simple, lightly stressed cars, and the ones that survive tend to have had their oil changed and not much else. Nothing here has an oil life monitor, so every interval below is fixed.
SUSPENSION
Campaign #10E002000 · Nov 2, 2010
Issue: RIDE CONTROL IS RECALLING CERTAIN FRONT STRUT MOUNTS BRANDED AS GABRIEL RIDE CONTROL OR ARVINMERITOR, P/NOS. 142435, 142193, 142305, 142303, SOLD AS REPLACEMENT EQUIPMENT FOR THE VEHICLES LISTED ABOVE. THE AFFECTED FRONT STRUT MOUNTS DID NOT CONTAIN A WELD JOINT BETWEEN THE BEARING HOUSING AND THE RATE PLATE.
Risk: THE ABSENCE OF THE WELD CAN ALLOW THE STRUT TO COME OUT OF ITS MOUNTING POSITION UNDER CERTAIN EXTREME DRIVING CONDITIONS WHICH COULD CAUSE DAMAGE TO SURROUNDING VEHICLE COMPONENTS INCREASING THE RISK OF A CRASH.
Fix: RIDE CONTROL WILL NOTIFY OWNERS OF RECORD AND REPLACE THE AFFECTED PARTS FREE OF CHARGE. THE SAFETY RECALL BEGAN ON MARCH 15, 2010. OWNERS MAY CONTACT RIDE CONTROL AT 1-248-458-1396.
WHEELS:LUGS/NUTS/BOLTS/STUDS
Campaign #90V191000 · Sep 11, 1990
Issue: LUG NUTS THAT RETAIN WHEELS AND WHEEL COVERS MAY HAVE BEEN TORQUED TO LOWER THAN RECOMMENDED SPECIFICATIONS.
Risk: INSUFFICIENT CLAMPING OF LUG NUTS RETAINING THE WHEELCOVER AND WHEEL COULD RESULT IN A LOOSE WHEEL THAT COULD FALL OFF WITH POTENTIALFOR LOSS OF CONTROL AND AN ACCIDENT.
Fix: REMOVE ORIGINAL WHEEL COVER, TORQUE LUG TO SPECIFICATION, AND INSTALL FULL WHEEL COVERS THAT ARE RETAINED BY SPRING CLIPS.

Critical for safety and preventing major damage
3,000 miles under the severe schedule, which is where a thirty-year-old small engine belongs, and at least once a year no matter the mileage. The Metro's three-cylinder holds barely three quarts, so a small loss is a large percentage of the sump. Check the level often.

~$120–$160
Shop
~$85–$115
DIY
~$25–$55
Full synthetic costs more than conventional. 5-quart 0W-20 + filter is the typical bill.
The Prizm's Toyota engine and the Metro's small Suzuki engines use a rubber timing belt due around every 60,000 miles. The good news is that the Toyota engines in the Prizm are non-interference, so a snapped belt strands you rather than destroying the engine. Replace the water pump and tensioner in the same job either way.

Pro only
On interference engines, a snapped belt destroys valves. Worth doing on schedule. Bundle water pump + tensioner — labor is already there.
Rotate every 7,500 miles and check the sidewall date codes. On cars this light and this old, tires are almost always retired by age rather than tread wear.

Free
Often free at the shop where you bought the tires — worth asking before paying.
Inspect pads, shoes, hoses, and hard lines at every service. Most of the lineup uses rear drums, and the hardware seizes on cars that sit. Rusted steel lines are the real risk on anything that lived where roads get salted.

Free
Most shops do this free as a courtesy with any service. Don't pay separately if you can avoid it.
Replace every 2 years. It costs very little and it is what keeps a small master cylinder and a set of light calipers working on a car this old.

~$180–$200

DOT 3 or 4 — match the cap. Vacuum bleeders make this a one-person DIY.
Keeps your vehicle running smoothly and efficiently
30,000 miles on copper plugs, longer on platinum. Replace the plug wires and distributor cap at the same time on these engines. Ignition parts of this vintage break down before the plugs do, and the symptoms look identical.

~$285–$390

~$25–$100
Iridium plugs cost more but last 100k+ miles. V6/V8 access varies wildly — some are tough.
Drain and fill every 30,000 miles. The automatics take Dexron. The manual gearboxes, which are common on the Metro and Tracker, take gear oil rather than automatic fluid, so confirm which you have.
Estimated cost — typical U.S. ranges
Dealer
~$330–$500
Shop
~$235–$355
DIY
~$60–$180
Some sealed transmissions have no dipstick — fill is precise and best left to a shop. Many drivers can still DIY drain-and-fill.
Replace every 15,000 miles. Small-displacement engines lose noticeable power and fuel economy with a restricted filter, and the part costs almost nothing.
Estimated cost — typical U.S. ranges
Dealer
~$60–$95
Shop
~$45–$70

~$15–$40
5-minute job on most cars; the airbox lid usually has clips, no tools needed.
Applies to four-wheel-drive Trackers. Change every 30,000 miles and after any water crossing. The Tracker uses a real part-time four-wheel-drive system with a transfer case and two differentials, each holding its own fluid.
Estimated cost — typical U.S. ranges

AWD/4WD vehicles only. Easy drain-and-fill on most platforms.
Extends the life of your vehicle and improves comfort
Every 3 years. These use conventional green coolant, not a long-life formula, so modern five-year intervals do not apply. Have the radiator and hoses inspected at the same time.

Use the manufacturer-specified coolant — wrong color/chemistry can damage the cooling system.
Test the battery and alternator once a year and clean the terminals and ground straps. On cars this small a marginal battery causes hard starting long before it fails outright.

~$225–$390

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.
