‘21 GMC Sierra with 2.7 turbo is done…..

Wife’s truck with 76k miles
4-5k mile oil changes
Highway miles
Misfire on cylinder 4
Changed plugs - didn’t help
Changed coil - no help
Had injector changed - no help
Now I’m in for over $1k and didn’t fix problem
Next step is pull engine apart to check lifters or cam minimum 20 hours work with no guarantee to find/fix problem…
I traded truck in and took $1k hit for misfire and check engine light…..
Hoped to get another three years out of it..
Happy new year!
My ‘18 tundra still running strong at 120k miles with only brakes, oil, filters and tires changed….
That 2.7 engine has a great reputation so far, you just never know….
Just thought I’d post to vent.

 

Bummer :/

Car trouble sucks. New car trouble really sucks. At least your tundra is still running strong.

 

Bummer to hear. Good luck with repairs or something new.

 

Sorry to hear that. Glad you were able to dump it. Hang on to that Tundra.

 

This sucks, I'm glad you were able to get out of it. I personally haven't heard anything good about the turbomax. They have a reputation for having leaky fuel injectors, that could've been the cause of your misfire.

Just one more ten billion dollar, taxpayer funded bailout and GM will be "PERFECT"; you watch!

 

Those are inherent risks of deviating from UR/UZ.
