Back in '95, I had a '90 GMC Sierra in Michigan. The beast had a temper, especially with the fuel pump acting up - felt like an adventure every time! Rust was a real pain on the older models, rust more than a myth up north. The suspension took a beating on pothole-ridden roads, too! Love that truck, but boy, it was a handful! Anybody else had the same issue? My bulb just flickered the night before!
In Ottawa, I’ve had my fair share of battles with my '90 GMC Sierra. The rear suspension always sounds like a symphony of rattles, especially when hauling heavy stuff. Also, the electrical system is a nightmare sometimes—lights flickering on a dare! Plus, folks never tire of telling me about the famous fuel pump failure. But hey, nothing beats tearing around with a '90 truck in this weather, right? It’s a classic, just needs love!
I’ve got a ‘90 GMC Sierra in Toronto and I’ve had my fair share of issues. The electrical stuff always gives me grief—lights flickerin’ off or the radio actin’ up. Rust’s a nightmare too! And folks, don’t get me started on those old Oxy sensors, nearly gave me a heart attack tryin’ to fix one last summer. Just a classic case of age showin’ itself, ya know?
Living in Ohio, I’ve seen a bunch of '90 GMC Sierras around. The 4x4 system is a real pain, folks – we were always messing with it. And don’t get me started on those engines; they love oil leaks. Mine was a goner after a few winters! Electrical issues were common too. But for the ride, they’re tough little trucks, just need a lot of TLC. Happy truckin’ to all Sierra owners! 
I’ve owned a few '90 GMC Sierra, n west Tex, and let me tell ya, they’re solid trucks, but they’ve had their quirks. Common issues include the shifter acting like it’s possessed, sometimes it’s real hard to shift into low or reverse. Also, that infamous crank-cambelt vibe that can really haunt ya if ya ain’t keepin’ an eye on it. But overall, they’re tough ol’ beasts!
I’ve got a '90 GMC Sierra and man, the head gaskets are notorious! Had to replace mine thrice already. I heard the cooling system just gives up back east in Canada during those crazy winters. And don’t get me started on the tailgates; mine fell off twice, once in the parking lot, and everyone at work laughed. It’s a fun ride, but gotta stay on top of it. Boom.
