Exclamation 2014 Equinox - Dealer says I have a "Fuel Rich" code.

We have been dealing with our 2014 Equinox throwing a "Stabilitrack/Engine Power Reduced" error and then losing power. We've had it at the dealer and they have said it's a peddle sensor issue and replaced it. It's been running fine and then out of the blue it did it again. This time the dealer is saying it's the peddle sensor AND says it now has a "Fuel Rich" error...saying that we have fuel in the oil... Where the **** did this come from? Does anyone know if this is a common issue...and what would cause it ?

I have never heard of a peddle sensor. Perhaps a pedal sensor?

If you have the 2.4L 4-cylinder, the high pressure fuel pump is probably failing and causing fuel to enter the engine crankcase. This will destroy the engine rather quickly. Check the engine oil via the dipstick. The fuel dilutes the oil, raising the oil level, and it will smell like gasoline.

A family member had a 2013 Equinox 2LT with the 2.4L engine. The high pressure fuel pump failed at 38 months, but with only 33,xxx miles on it. GM did not consider the high pressure fuel pump part of the power train warranty, so they had to pay over $500 for the repair (GM paid for the tow to the dealership). I dealt with the dealership, as I waited for the tow for them.

GM extended the warranty on the high pressure fuel pump on the 2.4L engines prior to the 2013 models (back to 2010). The dealer told me that the pump design had changed for 2013. I later checked the GM part numbers, and they were the same for the 2013 and prior year engines.

My family members were so upset with the poor quality of the Equionox (purchased new and never damaged or wrecked), they traded it for a 2017 Dodge Grand Caravan SXT and love it. They said they will NEVER buy another Equinox due to GM’s poor quality.

Thank you!

...and sorry...peddle / pedal...that's what happens when your wife calls saying the dealer now has a new issue after 1500.00 in repairs...a whole new level of frustration.

Buys a Chrysler vehicle and complains about GM quality......

Somebody is going to be in for a very rude awakening.

They bought a Caravan not an Odyssey or Sienna. Literally the only vehicle I've ever seen come into the shop with 3 bad wheel bearings at the same time.

Now - 2018 Equinox 2LT 2.0T AWD
Was - 2015 Equinox 1LT 3.6 AWD

I have owned GM vehicles for more than 40 years - and still own them. My family currently has three GM vehicles. Ironically, my family members have owned the 2017 Grand Caravan for 15 months now and have had ZERO problems.

The engine problems with the 2.4L 4-cylinder engine, including the high-pressure fuel pump, used in the 2010 - 2017 Equinox / Terrain models are WELL documented and discussed on this forum often. GM has issued several “satisfaction campaigns” for the engine and fuel pump due it their poor quality.

In all my years, I have never seen a GM engine with more problems and defects that the 2.4L in this vehicle line. Ask the OP what he thinks of the engine and high pressure fuel pump.

Huh? I thought a “Fuel Rich” code was about the ECM dumping too much fuel into the combustion chamber because it was responding to its input(s) telling it there was increased air input? And so your Fuel Trim goes to a high positive number. Is that what’s happening?

Are you saying the dealer is telling you “Fuel Rich” means fuel in your oil?

Maybe there is some confusion here with the terminology? I’ve never heard of the ECM being able to detect fuel in oil, but it certainly would be a nice feature to have.

Easy there big guy, wasn't meant as a personal comment nor was it a defense of GM.

And yes, I'm quite aware of the problems with the 2.4 engine. All of my customers with the 2.4 have had the oil consumption issue.

I just find it ironic that your family members deem something unreliable and then buy something just as unreliable. 15 months and they have zero problems really is not surprising nor impressive. Once it's out of warranty and the repairs start adding up, they'll find out. All Caravan owners do.

I apologize if I offended you, it was not my intent.

You didn’t offend me - no offense taken or implied.

After the dealer replaced the high pressure fuel pump on my family member’s 2013 Equinox 2.4L, it began making an odd noise at start-up and began using oil. The dealer assured us that the fuel in the oil did no damage, but we weren’t convinced. We caught the fuel pump leak early, as we checked the oil level often and saw the high oil level (and smelled fuel). We didn’t start or drive it then, but had it towed to the dealer. Trading the vehicle was one way to never have to worry about GM fixing the engine (which would probably wear-out again prematurely).

My family member bought an extended warranty on the Grand Caravan for piece-of mind.

It has been my experience in many decades of owning and servicing GM vehicles, that their engines are very dependable as long as the oil and filter is changed regularly, and other basic maintenance done. The 2.4L is the exception and I have been surprised at the engines miserable quality and how the dealer’s give so many people the “runaround” to have it fixed. In our case, the vehicle was serviced at the selling dealer (where our family bought numerous new Chevrolet models).
