GENERAL MOTORS Battery

Across four EVs (all GM - Equinox EV, Prologue, Bolt, Volt) I've had not a single issue with the 12V battery. On my 2015 Volt I traded it in with the original battery... in 2023. That's almost 10 years old!

Pros: no issues, long lasting

GENERAL MOTORS Oil filter

I use an extension and swivel. I put the new O ring on the oil filter cap. Fifth, I install the new filter onto the cap. I'm not sure about your model with some Encore years, GM used two different oil filters. Your cap will tell you which one to use (UFI v. Hengst). Make sure you get the right one.

Pros: new filter onto cap
Cons: GM used two filters

GENERAL MOTORS Alternator

The OEM alternator is only 55 amps and costs nearly $400, which is stupid expensive and wholly inadequate for off-road lighting, audio amplifiers, and other additional accessories so I decided to go with the CS130D GM alternator, purchased for under $100 new (no core charge) and has a 130 amp capacity.

I'm getting 14.8v from the upgraded alternator at 700rpm and maintaining 14.2v when every possible accessory and light is turned on at idle.

Pros: 130 amp capacity, under $100
Cons: OEM is expensive, inadequate

GENERAL MOTORS Brake pads

GM uses a harder wearing pad material so that they can claim that brakes are "essentially maintenance free" because it will take forever and a day to burn thru them under normal use, but at the expense of louder brakes.

Pros: long lasting
Cons: louder brakes

GENERAL MOTORS Automatic transmission

A former GM engineer talked in detail about how he was pressured to cheapen the transmissions of existing cars every single model year. GM's relentless cheapening made it worse year after year. That's the culture you're betting on when you buy a GM product.

Cons: cheapened design, declining quality

GENERAL MOTORS Engine oil
ShotaInvestor
  • Warning light:
Rating 1.0

E terceiro, tu tá condenando teu motor com esse óleo, anulando qualquer possibilidade de reclamar com a GM quando essa correia esfarelar e arrebentar, por permitir que terceiros coloquem um óleo completamente fora da especificação exigida pela montadora.

Cons: óleo fora da especificação
Vehicle: Chevrolet
