Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“My 2004 Acura TL is my first car owned. When I put the car in drive I can only accelerate to 20-30mph on the highway. Because, the car would not accelerate on a straight way or up hills. This is a dangerous manufacture malfunction with Acura transmissions for the consumers financially and physcially. I would appreciate a recall being done on my 2004 Acura TL because I love this car and would love to keep it. I am a college student and do not have the money to install another transmission and the same thing happens again. …”
