I traded in the Sonic. I didn't expect to, but the dealership (NOT Chevy) "made me an offer I can't refuse". I love my new car dearly. I'm not here to promote other brands, so I'm not interested in discussing what kind of car I got. I simply want to express my disappointment. Until it started having so many problems, I really liked my Sonic. It offered a surprising amount of performance (tuned), and I always liked the look of it. In the 15000 miles that I had it, it went to the dealership for numerous recalls and service issues including warped rotors and chipping paint (after only 500 miles!). Then it developed the second gear grind. I lived with it. Then it developed the whining transmission. In investigating these issues on here it became apparent that there is no effective solution; there are inherent design flaws with the Sonic transmission (at least the 6 speed manual version that I had). I tried different fluid, additives, etc, and nothing helped. I'm completely disgusted with the garbage transmission that GM used. I'm completely disgusted by their inability to find an effective solution (other than replacing with another garbage transmission). I'm completed disgusted with all the problems that I experienced in 15000 miles. It's a shame that what should have been a positive experience turned into a terrible one. The Sonic was the most unreliable car that I ever owned. Despite the warranty, I got tired of having to make time to get the car to the dealership, again, and again. GM, if you're listening, shame on you. To all of you satisfied customers, keep up the good work, and good luck in finding 300HP.
