The 2021 Chevy Tahoe, Suburban, and Silverado have a ‘Service Engine Soon’ light appearing on the dashboard. Sometimes it blinks on and off, and other times it stays on. But General Motors may have a solution for new Chevy Tahoe, Silverado, and Suburban models with this issue.
Why does the 2021 Chevy Tahoe need engine service?
According to Torque News, some owners of new General Motors trucks and SUVs have been plagued by a ‘Service Engine’ light on their dashboards. Models with this issue include the 2021 Chevrolet Tahoe, Suburban, and Silverado. The GMC Yukon, Sierra, and Cadillac models may be affected as well.
Nothing puts confidence in a brand new ride like having a service engine light pop up, right? Some owners noticed that the light pops up and turns off intermittently, while others can’t get it to turn off.
But GM figured out what’s causing the service engine light to illuminate. A bad engine manifold pressure sensor could be to blame. Now GM has issued a service bulletin for dealerships to replace the sensor in vehicles with the problem.
Why isn’t this a Chevy Tahoe recall?
There isn’t a recall for the 2021 Chevy Tahoe and other Cadillac, Chevrolet, and GMC vehicles yet because this problem doesn’t appear to be dangerous. But it is a nuisance as the light could indicate a significant problem. Also, Torque News noted that more severe problems could occur if drivers ignore the light for an extended period.
General Motors hasn’t released how many vehicles are experiencing sensor problems, and replacing the bad engine manifold pressure sensor can only be done at dealerships. You may be contacted to bring your 2021 GM vehicle in to have the sensor replaced.
If your ‘Service Engine Soon’ light flashes on your dashboard, don’t hesitate to contact a local dealership. Call ahead to see if the sensors are in stock and schedule a maintenance appointment. The sensors will be replaced at no cost to vehicle owners.
How reliable is the Chevy Tahoe?
This engine sensor issue for the 2021 Chevy Tahoe made us wonder how reliable this massive SUV is. According to Consumer Reports, the 2021 Tahoe has a predicted reliability rating of two out of five, which is below average.
The predicted reliability rating is based on surveys that Consumer Reports sends out to thousands of vehicle owners, allowing them to report issues they faced with previous models. The data suggests that the main problems occurred with the 2013 – 2017 models.
A few of the issues include brake problems, suspension issues, climate system trouble, electrical system problems, drive system problems, transmission issues, and engine problems.
However, on a positive note, fewer issues have been reported on 2018, 2019, and 2020 Chevy Tahoe models. This may indicate that previous problems have been resolved for newer models.
So far, the National Highway Traffic Safety Administration has issued six recalls for the 2021 Tahoe. The front passenger seat had loose bolts, the seat belt bracket wasn’t adequately secured, the seat belt assembly wasn’t properly attached, there was a fuel leak, the seat belt in the second-row center seat failed, and damaged seat belts had a risk of breaking during a crash.
But these recalls caught issues early, and newer models should have been repaired. The Chevy Tahoe is still a safe bet, especially with the corrected seat belt and fuel leak issues. Remember, the service engine light doesn’t indicate a dangerous problem.
