Engine

3.3L V6

• Engine Knocking/Piston Slap
  • Description/Symptoms: A knocking or slapping sound emanating from the engine, especially during cold starts or acceleration. This can be indicative of excessive piston-to-cylinder wall clearance (piston slap). In more severe cases, it could indicate connecting rod knock, which is a sign of bearing failure.
  • Solution: A mechanic should diagnose the source of the sound with an engine stethoscope. In cases of piston slap, a heavier weight oil might mask the noise but isn’t a permanent fix. If connecting rod knock is the issue, engine repair or replacement is necessary.
  • Estimated Cost to Fix: $3,000 - $7,000+ for engine replacement/rebuild
  • Recalls: None Found
• Oil Leaks
  • Description/Symptoms: Visible oil leaks under the vehicle, a burning oil smell, and/or low oil levels. Common leak points include valve cover gaskets, timing cover gaskets, and the oil pan gasket.
  • Solution: Identify the source of the leak and replace the affected gasket or seal.
  • Estimated Cost to Fix: $150 - $500+ depending on the location and complexity of the repair.
  • Recalls: None Found
• Catalytic Converter Failure
  • Description/Symptoms: Check engine light with codes P0420 or P0430 (catalytic converter efficiency below threshold), decreased engine performance, and/or a rattling noise from the exhaust.
  • Solution: Replace the catalytic converter. Ensure the upstream issues causing the failure (e.g., excessive oil consumption) are addressed to prevent premature failure of the new converter.
  • Estimated Cost to Fix: $800 - $1500+
  • Recalls: None Found

Transmission

6-Speed Automatic

• Harsh Shifting/Hesitation
  • Description/Symptoms: Rough or jerky shifts, particularly between certain gears. Hesitation when accelerating from a stop or when shifting gears.
  • Solution: Start with a transmission fluid flush and filter change. If the problem persists, a software update (if available) may help. In more severe cases, valve body repair or replacement, or transmission rebuild/replacement might be necessary.
  • Estimated Cost to Fix: $150 - $300 for fluid flush, $500 - $1500+ for valve body work, $3000 - $5000+ for transmission replacement.
  • Recalls: None Found
• Transmission Slipping
  • Description/Symptoms: Engine RPMs increase without a corresponding increase in vehicle speed. The transmission may also make whining or other unusual noises.
  • Solution: Check the transmission fluid level and condition. If the fluid is low or contaminated, address the underlying leak or contamination issue. A transmission rebuild or replacement is often required for slipping.
  • Estimated Cost to Fix: $3000 - $5000+ for transmission replacement.
  • Recalls: None Found

Suspension

• Worn Struts/Shocks
  • Description/Symptoms: Bouncy ride, excessive body roll when cornering, nose dive during braking, and/or fluid leaking from the struts/shocks.
  • Solution: Replace the worn struts and/or shocks. It is generally recommended to replace them in pairs (both front or both rear).
  • Estimated Cost to Fix: $300 - $800+ per pair, depending on the brand and labor rates.
  • Recalls: None Found
• Broken/Worn Coil Springs
  • Description/Symptoms: Sagging suspension, uneven tire wear, clunking noises when driving over bumps, and/or visible cracks or breaks in the coil springs.
  • Solution: Replace the broken or worn coil springs. As with struts/shocks, it’s best to replace them in pairs.
  • Estimated Cost to Fix: $300 - $700+ per pair, depending on the brand and labor rates.
  • Recalls: None Found

Electrical

• Battery Drain
  • Description/Symptoms: The battery drains quickly, especially when the vehicle is not in use. Difficulty starting the vehicle, even with a relatively new battery.
  • Solution: Perform a parasitic draw test to identify the source of the drain. Common culprits include faulty relays, aftermarket accessories, and malfunctioning electronic modules.
  • Estimated Cost to Fix: $100 - $500+, depending on the source of the draw.
  • Recalls: None Found
• Malfunctioning Sensors (ABS, TPMS, etc.)
  • Description/Symptoms: Warning lights on the dashboard (ABS, TPMS, etc.), inaccurate readings from the sensors, and/or system malfunctions.
  • Solution: Diagnose the specific sensor fault using a scan tool and replace the faulty sensor.
  • Estimated Cost to Fix: $100 - $300+ per sensor, depending on the sensor type and location.
  • Recalls: None Found
• Faulty Power Liftgate
  • Description/Symptoms: Power liftgate fails to open or close automatically, makes unusual noises, or operates erratically.
  • Solution: Check the liftgate struts, motor, and latch mechanism. A scan tool may be needed to check for codes related to the liftgate system. Replace faulty components as needed.
  • Estimated Cost to Fix: $200-$800+, depending on the parts needed and labor.
  • Recalls: None Found

Exterior

• Rust
  • Description/Symptoms: Rust forming around wheel wells, door panels, and undercarriage.
  • Solution: Treat the rust to prevent spreading. Sand affected areas, treat, prime, and paint. If there is structural damage, cut out rusted areas and weld in new sheet metal.
  • Estimated Cost to Fix: $100-$1000+

Interior

• Air Conditioning Issues
  • Description/Symptoms: A/C blows warm air, inconsistent air temperature, or unusual noises from the A/C compressor.
  • Solution: Check the refrigerant level and inspect for leaks. If there is a leak, repair it and recharge the system. If the compressor is faulty, replace it.
  • Estimated Cost to Fix: $150 - $300 for refrigerant recharge, $500 - $1200+ for compressor replacement.
  • Recalls: None Found
