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.

NHTSA — Power Train 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

This car has had multiple issues with the SRS system, which has rendered it inoperable. Apparently, there are design issues with the seat buckle and seat sensor that have been there all along. There are multiple owner complaints here and on the internet about this. This apparently makes the entire SRS system inoperable, including the driver airbag. This along with the well documented transmission issues make this a "rolling coffin"-- I am not sure why Honda is not concerned about the safety of its owners. I guess it would take major injuries and lawsuits and publicity to get some action.

Contacted duncan Acura in roanoke, va. Transmission drops speed from 70mph to 10 mph without warning on highway. Was told transmission was repaired when recall came out but car had too many miles on it now 223,000. The service manager at duncan would not return my calls or schedule to get transmission inspected after I understood that I would need to pay for the inspection. Contacted Acura headquarters and they issued a claim & claim rep to help out. Never will trust duncan Acura with a safety issue. Just wanted to know if this issue was the same as the earlier recall was for on these cars. Not safe to drive and Acura dealer would not take the time to inspect it. Still waiting on response from Acura been 4 days.

Transmission lockup at highway speeds. Vehicle would drop speed from 70 mps to 10 mps without warning in a matter of seconds almost causing loss of control & crash with cars following on highway. As described in Acura service bulletin 04-020. Car was fitted with repair part but did not prevent it from occurring again over time & miles from driving.

Transmission failure. This is a safety hazard as the transmission stalls and then slams into gear. I no longer feel safe to drive this car. I had to pay a great amount of money to fix my defective transmission.

CL 6-cyl

  • 32,437 miles
Summary: I own a 2001 Acura Cl with 32,437 miles on it. The car has been perfectly maintained. While driving approximately 20-30 mph, the transmission slipped hard between first and second gear jerkily, and the rpms increased. The vehicle was taken immediately to a dealer where it was diagnosed that the transmission needed to be replaced. I inquired about any recalls regarding transmission and the dealer stated that the vehicle was previously repaired under NHTSA campaign id number: 04V176000 (power train: Automatic transmission). I didnt remember. I feel strongly that the failure was either not corrected properly, or that Acura corporation failed to properly identify this serious and recurring issue. My car has been driven about once a week since purchase and a few times for vacation. Given the low mileage and regular maintainence I feel this $4,511.39 repair issue is one I cannot afford to ignore. It should have at least included a lifetime warranty, instead of 3 years or 36,000 miles. Do I have any recourse or is this a forum simply for complaints?

I took my car to nalley Acura 1355 cobb pkwy. South marietta Georgia 30060 I was told that 2 jetters was put into my transmission and they took a picture and sent it too the manufacturer. I asked for a record of the maintenance I never got one [xxx] the service tech. Said that I would be mailed one. I do not believe the picture that was sent to me was of my transmission, cause it took days for them to come up with this picture and I did not see my name by it or my VIN number. The info the company sent me was out of a book that was showing me a diagram of a transmission. I stood there for 4 hours and all that was done was my hood was raised an no one hardly touch my car. It was never put upon a jack or raised to a level where you could get a good look a the transmission. Information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

Parked car. Moved transmission lever to what I thought was park (push straight up). Started to swing out of car putting weight on outside foot. The transmission was actually in neutral and the key was removed - it can be removed in any gear position just like the 2001 Honda Accord recall says. The Acura of the same year never had the recall even though it is using the same defective part numbers. Car started to roll backwards and I was forced to stop car using foot and hand pressure resulting in slight sprain to wrist requiring no additional care. This is a troubling safety issue that was actually recalled for Honda brand vehicles only ignoring Acura brand defects.

I own a 2001 Acura 3.2 Cl type S. I was driving my car (approx 45 mph) on a busy two-lane road yesterday when my car suddenly stopped responding to the accelerator being pressed. I had cars coming at me at a high speed behind me. I saw an opening in oncoming traffic so that I could turn and get myself and my child out of harm's way. When I turned left, my car (I guess) downshifted and came to an almost complete stop with cars coming behind me and at me!!! I thankfully safely got to the side of the road and have not driven it since. I have been told it sounds like complete transmission failure. Myself and my son could easily have been killed! what do I do" am I responsible for paying to replace transmission"

The vehicle transmission failed at 18700 miles. The consumer received a notice that the manufacturer was extended the warranty on the transmission. A little over a year later the consumer transmission failed and was replaced with a new one. The consumer then received a recall on the transmission and had it replaced a second time. Now the transmission is starting to slip again.

The transmission failed prematurely. The part had been replaced three times, however the problem recurred. The transmission would slip and delay shifts. The downshifts were sometimes harsh. On at least two occasions when downshifting to pass other vehicles on the highway, the vehicle would feel as if the transmission had gone dead and then shift.
