So My 2019 Chevy Colorado Z71 Stood at The Dealership Nearly 3 Weeks for a One-Day Job, on The Way Back Gets Check Engine Light and The Dealer Wants $1,300 To Fix It

After waiting nearly 3 weeks for what should have been a one-day repair, Steve picked up his 2019 Chevy Colorado, only for it to throw a check engine light on the way home. Now the dealer is demanding another $1,300 to repair it.

Buying a new vehicle comes with an expectation of reliability, especially when you take extra steps to maintain it properly. But what happens when, despite your best efforts, your truck still runs into issues, and the dealership you rely on makes the experience even worse? This experience is similar to what happened to Steve S., a Chevy Colorado Z71 owner, who shared his frustrating ordeal after taking his well-maintained truck to the dealership for repairs.

Two days ago Torque News senior reporter Denis Flierl published an interesting article about a Toyota owner taking a chance on a Silverado and experiencing some problems at 5,000 miles. Steve was one of the many readers who shared his experience and wrote the following comment.

"I have a Chevy Colorado Z71 (2019), bought new with a couple thousand miles on it. I always serviced this truck at the dealer. I have done all maintenance, including oil changes, ahead of recommendations. So you know, I also changed the transmission fluid at about 49,000 miles. Then at 55,422 miles the transmission control mod code came out, 75 days outa warranty by time, not miles. The dealer replaced the valve body in transmission. It was supposed to be a one-day job, but took nearly 3 weeks, and more than $2500. On the way home from picking it up, the truck gets check engine light (code for coolant temperature sensor). And now the dealer wants another $1300 to replace it. Long story short, I traded that thing in for different vehicle, and just took the loss."

Steve’s story highlights a crucial issue that many vehicle owners face—not just the mechanical problems that arise but also how dealerships handle repairs. In this case, while it’s easy to blame the truck itself, the real problem might be the dealership’s service quality. The three-week delay for a one-day repair raises serious questions about the competence or efficiency of the service center. And then, having another problem immediately after picking up the truck, followed by a costly repair quote, makes one wonder if Steve was dealing with an inept dealer rather than an inherently unreliable vehicle.

Common Issues With the 2019 Chevy Colorado Z71

Steve’s transmission control module failure is not an isolated case. Some 2019 Chevy Colorado owners have reported similar issues, particularly with the 8-speed automatic transmission, which has been known to suffer from hard shifting, torque converter shudder, and occasional electronic faults. However, GM has issued service bulletins to address these problems, and many owners have had positive experiences after following recommended maintenance procedures, like early transmission fluid changes.

Another issue, as Steve encountered, is the coolant temperature sensor failure. This sensor plays a critical role in regulating engine performance, and its failure can lead to erratic temperature readings, reduced fuel efficiency, or even limp mode activation. While $1,300 for a replacement might seem high, some owners have opted for independent mechanics or DIY fixes to lower the cost significantly.

Still, it’s worth noting that Chevrolet has been making strides in improving the Colorado. The latest model, the 2023 Chevrolet Colorado has already racked up awards, proving that GM continues refining and improving the midsize truck lineup.

Why the Chevy Colorado Still Holds an Edge Over Its Competitors

Despite Steve’s frustrating experience, the Chevy Colorado Z71 remains a strong contender in the midsize truck segment. It offers a more comfortable ride than many of its rivals, thanks to its well-tuned suspension. The Z71 off-road package adds capabilities that trucks like the Toyota Tacoma TRD Off-Road and Ford Ranger Tremor struggle to match in terms of ride smoothness.

Additionally, the Colorado's available diesel engine option provides excellent fuel economy and torque, making it an attractive option for those who need a midsize truck for towing. Compared to the Tacoma, which often receives criticism for its outdated transmission and interior, the Colorado provides a more refined driving experience. The Ford Ranger, while powerful, has been noted for its stiff ride and less engaging handling. So, while the Chevy Colorado has its fair share of issues, it also brings a lot to the table that makes it worth considering.

For off-road enthusiasts, the 2024 Chevy Colorado ZR2 Bison is another exciting upgrade that offers some of the best-in-class features, making it a top choice for rugged terrain.

Another area where the Colorado shines is mountain driving. The 2024 Chevrolet Colorado has proven itself as one of the best midsize trucks for handling steep grades and rough terrain, something that adventurers and outdoor enthusiasts will appreciate.

Even in GM’s own lineup, the battle between the Chevrolet Colorado and other models like the Silverado EV is heating up. If you’re wondering how the Colorado compares in the broader Chevrolet lineup, check out this in-depth look at the 2024 Chevrolet Colorado vs. 2024 Chevrolet Silverado EV to see how these models stack up against each other.

Stories of unexpected costs at dealerships are all too common, but sometimes, surprises in the automotive world aren’t just about repairs - they come in the form of unexpected deals. Just ask one driver who stumbled upon an offer that seemed too good to be true: 200 kWh of charging for just $4.99 a month with his Mustang Mach-E, right in front of his LA Fitness. While Steve S. was hit with a hefty repair bill, others are scoring unbelievable savings in the EV world—proving that sometimes, the automotive industry delivers the unexpected in ways you’d never imagine.

What’s Your Experience With Dealership Repairs?

Steve S.'s story raises an important question: was the real problem his truck or the dealership's poor service? Have you had a similar experience with long repair times or expensive post-repair issues? Also, if you own a Chevy Colorado, how has it performed for you compared to other midsize trucks?

Temp sensor is less than a 2 hour job. Thermostat at the same time with new coolant is just over $100 if you do it yourself.

I’m not sure if you were replying to someone or not but it is absolutely uncanny that this comment is on here. My 18 z71 threw a code a couple weeks ago for coolant temp too low to be regulated by thermostat. Common fix recommended was a thermostat but I ordered that and a temp sensor. Took me about an hour. I did check with a local shop and they quoted me $600 because they said the book time was like 11 hours but they were confident they could beat that. In the end I paid $75 for parts, $20 for a jug of coolant. I just hit a deer in November so I was pretty confident the rest of it was fresh from the repair. Wish all repairs went together that easy

I would say opt for independent shops. Dealerships are known to be more expensive as they specialize in warranty service primarily. Try an independent shop.

I drive a 2016 Colorado Z71. It's been a pretty solid truck compared to the other model years previous and after it. Thank goodness. However, I too have experienced 1 day repairs that have stretched into days, fortunately not weeks. I've also had repairs that ballooned in cost as other issues were discovered - just a normal part of owning a 9yo truck in the salty northeast. Waiting for parts delivery plays a role, but I think workforce availability also plays a role. There aren't many trade jobs these days where employers will say they are fully staffed. A key note in this story would be what reason was given by the dealer as to the long wait for completion.

Don't go back to the dealership. You can have all warranty repairs completed at any shop you want.
I never use the dealer.

Maybe I missed it but why did it take 3 weeks? That's important information.
Also the check engine light came on after it left for a different reason so yah it's not free to repair. "Ever since you changed my oil my wiper blades chatter" is what that sounds like.

I have a 2019 Colorado and a 2018 camaro and they both have the 8 speed automatic transmission.(8L45 and 8L90) Both experienced road shutter "feels like driving on a rumble strip on the side of an interstate" Both had the transmission service and got better, but the truck still bucks when coming to a stop and then accelerating the shift is clunky. The camaro has 54,000miles and is currently getting the rear differential completely replaced. The dealer wanted $3200 for the repair.

My son had a 2019 Colorado key word is had. Dealership had my son truck from august 2 to March 4 to put in new transmission 7 months GM kept saying no eta for 6 months no truck to use my son was fortunate enough to be able to buy a new truck. Let’s just say was not a GM truck. GM lost a 26 year old for life on terrible service.

I will never buy a new GM product after that 1995 new S10 blazer me and my wife purchased in 95. The dealership new the cross fuel injection system was good for only 90k miles. All the companies are only out to make profits and not reliability. I'm keeping my old 1978 K5 and put a new moter when need it.

I never take my truck back to the dealer. I take mine to independent auto repair facilities. In the past I have had trouble with auto dealers who are pressuring their mechanics to make money. Higher prices and repairs that do not need to be done.
I look for some one who I can talk to and will be honest with me.
