Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

NHTSA — Service Brakes, Hydraulic: Foundation Components: Disc: Rotor Problems Notes: The automatic transmission on the 2nd generation CL (2001-2003) is a downshifting mess. According to reports it slips, flares, and eventually fails --- sometimes around 40,000 miles.

The troubled transmission got an extended warranty for some CL owners that was later extended even further thanks to a class-action lawsuit in the United States. But even with the extended warranty, the transmission in this car is well known for overheating and locking up suddenly and without warning.

2001 Acura CL Owner Comments

problem #3

Dec 092004

CL 6-cyl

  • Automatic transmission
  • 64,000 miles


2001 Acura Cl type S, front brake rotors warping: At 34000 miles, the brake discs had warped. I took the car to the dealership, and after I showed them the Acura technical service bulletin 01-017 about warped brakes, they agreed to resurface the brakes under warranty. At this time the two service writers acknowleged that the brake rotors were a weakness on the Acura TL and Cl, that they serviced about ten cars per week for this, and that they had put new brake rotors on their personal vehicles. 14000 miles later, at 48000 miles, the rotors were warped again, and I persuaded them to replace the rotors with new ones under warranty. (I paid for new pads.) now, 16000 miles later, at 64000 miles, the new rotors have warped. I am a mechanical engineer, and I know how to drive to cause the least amount of heat build up in the rotors, so this is a case of underdesigned rotors.

Brake rotors were severly warped. This is normally a wear and tear item and is expected to require replacement; however, Acura knows of a manufacturing defect with the brakes on at least the 2001 3.2 Cl and 1999-2001 TL vehicles as evidenced by tsb 01-017. This is the second time I've required the rotors to be replaced (not just resurfaced) in 45,000 miles. First time at around 25,000, second now at 45,000. There is no reason the rotors should have warped a second time since the tsb was addressed and the new pads and rotors should have prevented the heat issue that leads to warping. This was obviously not the case. The tsb does not fully correct the issue and can lead to a dangerous situation as the brakes are not taken in for service.

While braking at high speeds steering wheel vibrated. Dealership was notified, but did not resolve the problem.
