• Shift solenoid failure: The shift solenoid can fail, preventing the transmission from shifting correctly. Symptoms include delayed or harsh shifts, lack of acceleration, and check engine light illumination. The solution is to replace the shift solenoid, which can cost between $300 - $800+.

6-Speed Automatic

• Transmission fluid leaks: The transmission can develop fluid leaks, causing a loss of fluid and potential damage to the transmission. Symptoms include visible leaks, low transmission fluid levels on the dipstick, and check engine light illumination. The solution is to replace the leaking component, such as a seal or gasket, which can cost between $200 - $600+.
• Shift quality issues: The transmission can experience shift quality issues, such as rough or delayed shifts. Symptoms include difficulty shifting, a lack of acceleration, and check engine light illumination. The solution is to have the transmission serviced or reprogrammed, which can cost between $200 - $500+.
• Valve body failure: The valve body can fail, preventing the transmission from shifting correctly. Symptoms include difficulty shifting, lack of acceleration, and check engine light illumination. The solution is to replace the valve body, which can cost between $1,000 - $2,000+.

Suspension

• Front upper control arm failure: The front upper control arms can fail, causing a loss of control and potential accident. Symptoms include excessive tire wear, a clunking or rattling noise from the front end, and difficulty steering. The solution is to replace the control arms, which can cost between $500 - $1,000+ per side.
• Rear leaf spring failure: The rear leaf springs can fail, causing the vehicle to sag and lose stability. Symptoms include a rough ride, a sagging rear end, and difficulty handling. The solution is to replace the leaf springs, which can cost between $500 - $1,000+.
• Shock absorber wear: The shock absorbers can wear out over time, causing a loss of stability and ride comfort.
