What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
My 1998 acura slx, with 122,000 miles, requires a new engine. The car developed a loud slapping noise and was diagnosed by 2 mechanics as a broken piston skirt. I was told that this is a common issue with these cars - a result of a mismatch between the isuzu engine and the acura transmission.
In june of 2003, we took our 1998 acura slx w/45k miles on it into stevens creek isuzu dealership for a major service and to check out the "pinging/grinding" noise that we had been hearing for a long time. We were told they couldn't duplicate the noise.
Consumer stated she heard knocking and a loud pinging noise coming from the engine. She then pulled over and her husband checked the vehicle and saw that the oil was empty although she had an oil change before the trip. All of the oil spilled from the engine. Engine had blown.
Throttle sucked to the ground and would not release when brakes applied, when emergency brake was extended.
Unable to steer straight line at 70 mph 95 degrees, wanders over road, okay when tires cold. ( dot number: cll417 tire size: p245/70r16 )
The quick disconnect gas tank connection came loose on the highway. Driver is unaware of leak until made aware of it by someone else.
