Suzuki X90 Problems

The Suzuki X90, a quirky and undeniably unique two-seater SUV produced from 1995 to 1997, holds a special place in automotive history. While its distinctive t-top design and surprisingly capable 4x4 system have garnered a cult following, owning an X90 isn't always smooth sailing. These little SUVs, now decades old, come with their fair share of common problems, and understanding them is crucial before you even think about buying one.

So, What's the Deal with the X90's Reliability?

Let's be honest: the Suzuki X90 isn't exactly known for bulletproof reliability. It shares many mechanical components with the Suzuki Sidekick/Vitara, which helps with parts availability, but age and the inherent design quirks of the X90 contribute to a number of recurring issues. While many owners lovingly maintain their X90s, keeping them running strong, potential buyers should be aware of the challenges they might face.

Rust: The X90's Arch-Nemesis

Rust is arguably the biggest enemy of the Suzuki X90. Like many vehicles of its era, the X90 is susceptible to corrosion, especially in areas prone to road salt or humid climates.

Frame Rust: This is the most critical area to inspect. Severe frame rust can compromise the vehicle's structural integrity, making it unsafe to drive. Pay close attention to the frame rails, particularly around the rear suspension mounts and the areas near the body mounts.
Body Panel Rust: Common rust spots include the rocker panels, wheel arches, door bottoms, and around the t-top seals. While body panel rust is less critical than frame rust, it can still be costly to repair and detracts from the vehicle's appearance.
Underbody Rust: Check the floor pans, fuel tank, and exhaust system for signs of rust. A thorough inspection with a flashlight is recommended.

What to do about it: Prevention is key. Regular washing, especially during winter months, and undercoating can help slow down the rust process. For existing rust, proper treatment involves removing the rust, applying a rust converter, and then painting. In severe cases, welding may be necessary to repair or replace corroded metal.

The Infamous T-Tops: Leaks and More

The X90's signature t-tops are a defining feature, but they can also be a source of frustration.

Leaks: Leaking t-tops are a common complaint. The seals can dry out, crack, or become deformed over time, allowing water to enter the cabin during rain or car washes.
Fitment Issues: The t-tops may not always fit perfectly, leading to wind noise at higher speeds.
Latch Problems: The latches that secure the t-tops can become worn or broken, making it difficult to properly secure the tops.

What to do about it: Inspect the t-top seals carefully for any signs of damage. Replacements are available, but installation can be tricky. Applying silicone grease to the seals can help keep them pliable and prevent leaks. For latch problems, replacement latches can be sourced, but finding original parts may require some searching. Proper alignment of the t-tops is crucial for a good seal.

Engine Issues: Small but Mighty (Sometimes)

The X90 is powered by a 1.6-liter four-cylinder engine, which is generally reliable but can experience certain issues as it ages.

Oil Leaks: Oil leaks are common, particularly from the valve cover gasket, oil pan gasket, and rear main seal.
Overheating: Overheating can occur due to a clogged radiator, faulty thermostat, or worn water pump.
Sensor Problems: Sensors like the oxygen sensor, mass airflow sensor, and crankshaft position sensor can fail, leading to poor engine performance or a check engine light.

What to do about it: Regular maintenance, including oil changes and coolant flushes, is essential for keeping the engine running smoothly. Address any oil leaks promptly to prevent further damage. If the engine overheats, diagnose the cause and replace any faulty components. When sensor problems arise, use a diagnostic scanner to identify the affected sensor and replace it.

Transmission Troubles: Manual or Automatic Woes

The X90 was available with either a five-speed manual or a three-speed automatic transmission. Both can experience problems over time.

Manual Transmission: Common issues include worn synchros, leading to difficulty shifting gears, and clutch problems, such as a slipping clutch or a stiff clutch pedal.
Automatic Transmission: The three-speed automatic is known for being somewhat sluggish. Problems can include slipping gears, harsh shifting, and complete transmission failure.

What to do about it: For manual transmissions, replacing worn synchros or the clutch may be necessary. Automatic transmissions require regular fluid changes to prevent problems. If the transmission is slipping or shifting poorly, a rebuild or replacement may be required.

Suspension and Steering: Feeling a Little Loose?

The X90's suspension and steering components can wear out over time, affecting handling and ride quality.

Worn Suspension Bushings: Worn bushings can cause excessive play in the suspension, leading to a bumpy ride and poor handling.
Ball Joint Problems: Ball joints can wear out, causing clunking noises and affecting steering.
Steering Play: Excessive play in the steering wheel can be a sign of worn steering components, such as tie rod ends or the steering gear box.

What to do about it: Inspect the suspension and steering components regularly for signs of wear. Replace worn bushings, ball joints, and tie rod ends as needed. A steering gear box adjustment or replacement may be necessary to address steering play.

Electrical Gremlins: The Fun Never Ends

Like many older vehicles, the X90 can be prone to electrical problems.

Wiring Issues: Wires can become brittle or corroded over time, leading to shorts or open circuits.
Grounding Problems: Poor grounding can cause a variety of electrical issues, such as dim lights or malfunctioning accessories.
Instrument Cluster Problems: The instrument cluster can experience problems, such as faulty gauges or a dim display.

What to do about it: Inspect the wiring harness for any signs of damage. Clean and tighten any corroded connections. Ensure that all ground connections are clean and secure. If the instrument cluster is malfunctioning, it may need to be repaired or replaced.

Parts Availability: The Hunt for the Rare

While the X90 shares many parts with the Suzuki Sidekick/Vitara, some parts are unique to the X90 and can be difficult to find.

Body Panels: Body panels, such as fenders and doors, can be hard to find, especially in good condition.
T-Top Seals: While replacement t-top seals are available, they may not always be a perfect fit.
Interior Trim: Interior trim pieces, such as door panels and dashboard components, can also be difficult to source.

What to do about it: Online forums and enthusiast groups are a great resource for finding rare parts. Junkyards can also be a good source for used parts. Be prepared to be patient and persistent in your search.

Interior Issues: Age Takes Its Toll

The X90's interior can show its age, with common problems including:

Cracked Dashboard: The dashboard is prone to cracking, especially in areas exposed to sunlight.
Torn Seats: The seat upholstery can become torn or worn over time.
Faded or Broken Interior Trim: Interior trim pieces can fade, crack, or break.

What to do about it: Dashboard covers can help protect the dashboard from further cracking. Seat covers can be used to conceal torn upholstery. Replacement interior trim pieces can be sourced from junkyards or online.
