I have a good & positive story about these GM cars.
Back in the early 90's, a lady that I worked with drove these types of GM cars, mostly BUICK's all her life and never a 4 cyl. She had been hearing a great deal about HONDAs and how good of a car they were. Lots of folks we worked with were switching to HONDAs(and Toyotas too) mainly due to having many issues with their domestic vehicles however, this lady wasn't one of them. She never really had any serious issues with her BUICKs.
For her next car, she went out and bought a new HONDA Accord LX(1990-'91) and absolutely hated the car after the first year. She complained about so many things with her HONDA that all of our co-workers were astonished, especially since they were having such great success with theirs.
This lady wasn't a complainer. As the matter of fact, you'd have a hard time finding a more positive person to work with. Just some of the things that I can remember about her complaints with her Accord:
She hated the hard seats, the firm/harsh ride and noisy cabin and loud interior on the highway. The buzz of the 4 cyl engine And the OE tires needed replacing shortly after the first year and the factory radio was just terrible.
Oh, and there's more but, I can't remember all of the complaints she had but couldn't wait to get rid of the HONDA. IDK that she had any serious issues with the Accord but she said it was just a terrible car to drive! And also, IDK what she got for her trade-in(since Honda's carry a high resale value) but, she went back to BUICK.
