1999 Acura Slx problems

Common 1999 Acura Slx problems

Based on complaints from owners of the 1999 Acura SLX, several common problems have been reported. Here is a detailed list of these issues:

1. Transmission Shudder and Vibrations:
   • One common problem affecting many Acura vehicles, including the SLX, is transmission shudder and vibrations while driving, especially noticeable at highway speeds. This issue can often be corrected by updating the automatic transmission software, which typically needs to be done by a dealer. If a software update does not resolve the shudder, it may indicate a faulty torque converter that requires replacement, a repair that can be costly and complex.
2. Delayed Shifting Between Gears:
   • Some owners have reported issues with the transmission delaying shifting between gears, both during upshifting and downshifting. This problem can manifest with symptoms like a flashing check engine light, D4 or D5 indicator lights on the dashboard, and audible noises from the transmission. In many cases, resolving this issue may involve replacing the torque converter, especially if the vehicle is no longer under warranty.
3. Premature Wear of 3rd Gear Clutch Pack:
   • Another common problem in the 1999 Acura SLX is the premature wear of the 3rd gear clutch pack. This issue can lead to difficulties upshifting or downshifting in 3rd gear, causing symptoms like flaring, slipping, or issues specifically when shifting into third gear. Resolving this problem typically requires overhauling the transmission and replacing the 3rd gear clutch.
4. Idle Air Control Valve Malfunction:
   • The idle air control valve in the 1999 Acura SLX can malfunction, leading to high idling, revving up and down, or other irregular idling behaviors. Replacing the idle air control valve can often resolve these issues, restoring normal idling patterns in the vehicle.

These common problems with the 1999 Acura SLX can impact the driving experience and overall performance of the vehicle. It is essential for owners experiencing these issues to have their vehicles inspected by certified mechanics to diagnose and address the root cause of the problems promptly. Regular maintenance and timely repairs can help prevent further damage and ensure the longevity of the Acura SLX.

Why was the Acura SLX discontinued?

The SLX received a restyled front end for the 1998 model year, but continued to sell poorly and was ultimately discontinued after 1999. It is said that sales were affected by bad press when the 1996-1997 models were rated "Not Acceptable" by Consumer Reports for their tendency to roll over during testing.
