Quiet, Comfortable, Sooth & Well Designed
By Vivo | on Monday, January 01, 2018
I love the 2017 Chevy Malibu. This is the quietest car I have ever driven. Its so smooth on the highway. The car seems to naturally stay in its lane. The brakes are great. The car is very fuel efficient and will delivery about 45-mpg at 60-mph. The 1.5 liter Lt is not a race car, but has plenty of power and can easily execute quick maneuvers in traffic. Its really the best car in its class.… - 5.0
best economy class American on the market
By jay | on Monday, September 21, 2020
I got this car used at a very good low price for 20,000 miles. I got it to get off a bad lease and I was set to replace it later on. 3 years later this car has just been amazing and very reliable. It's not a fully equipped luxury ride but it's got all I need. The engine performs great. I only had one mechanical issue but GM issued a recall service notice and refunded me dollar for dollar. I have put over 65k on it and I see no reason to replace it… - 4.0
Like the car but to much technology and software
By Fred | on Monday, July 01, 2019
The car does perform well with power and the gas mileage is amazing. But setting that aside the car did require a repair after the first 300 miles. Wire harness was the claim. Second failure for the same thing at 12,000 miles. Second failure made the gauges read as if the alternator quit but again wire harness. At 22,000 the shifter failed. Computer thougt car was in gear. Due to software was not able to lock the car with a shifter failure computer thinks car is in neutral. 3 failures in a brand new vehicle under 25,000 miles seems poor quality to me. The technology amplifies the failures making the car not drivable.…
