Engine and cooling problems are among the most serious defects under California’s Song-Beverly Act. Owners of the 2020 Chevrolet Tahoe have reported issues including stalling, overheating, loss of power, rough idling, excessive oil consumption, and check engine lights that return after dealer repairs. With 16 NHTSA complaints on record, this defect pattern is well-documented. Owner reports include: “I sent this to GM Corporate on 2/12/2025: I’m writing regarding the recall on certain 2020 Chevy Tahoe transmissions. My husband is meticulous with his vehicles including all regular service updates and recommended appointments. It literally looks like it came off the showroom floor 5 years after buying it. Unfortunately, when returning on a trip our vehicle suddenly increased rpm’s and wouldn’t respond while going 65 miles per hour. Thankfully, it reengaged, and we were okay but imagine what could have happened! We managed to get it home, but while attempting to back up it wouldn’t shift. We had to have it towed and have been told our transmission is SHOT! It will cost us over $7000 to replace?!! We attempted to call the GM customer service number to Complain and see if they could provide some help. They put us in touch with a service manager in our area whose voicemail was full and took a week to connect with. She basically said there is nothing she can do as it is within the 5 years but over on miles. So, here we sit with a vehicle we have babied for 4.9 years that needs a new transmission. I am asking for you to listen. Asking for you to expand the investigation/recall to include ALL 2020 (or related) vehicles. Something isn’t adding up, and you are leaving customers who have paid off their $60,000 vehicle stuck with more $ to pay because of an about defect. This could have killed us. It literally froze while we were driving, and now we are without a vehicle waiting for a new transmission. We have never had issues with the transmission before. How does a transmission just go? Definite defect!” (NHTSA Complaint #11711865)
Electrical system failures are notoriously difficult to diagnose and repair, which often results in multiple unsuccessful repair attempts — a key element of a lemon law claim. Reported issues for the 2020 Chevrolet Tahoe include infotainment malfunctions, battery drain, warning lights, power window failures, and intermittent starting problems. 14 NHTSA complaints have been filed for this category. Owner reports include: “On multiple occasions, my car has locked my keys on the INSIDE of the vehicle. I have put things inside my vehicle before leaving and closed all the doors, upon returning, even just a few minutes later, my doors are locked and I am locked out of my vehicle. Additionally, my car is not detecting my remote. I cannot unlock my car with the buttons on the door and need to have my keys in hand for my car to detect the fob. Additionally, if someone opens the door while the car is running but in park, and then closes the door, the Car will beep as if there is no longer a remote detected. This has happened on multiple occasions. I have changed the batteries in the fobs multiple times, switched out my fobs so I was using a different fob and it has happened with both of my fobs.” (NHTSA Complaint #11709665)
Powertrain and transmission defects directly impair the vehicle’s core function and are generally considered substantial defects under California lemon law. Owners of the 2020 Chevrolet Tahoe have reported harsh shifting, shuddering, slipping, and transmission warning lights. 12 NHTSA complaints have been submitted for this defect category. Owner reports include: “Lifter failed on my Chevy Tahoe 6.2L engine at ~75K miles in September 2025. One lifter bank was replaced. No reason for lifter failure was given. Less than 5 months later the other lifter bank has failed and damaged the cam shaft. Again, no reason for failure was provided. Failed lifters can cause catastrophic engine failure, which is incredibly dangerous when the vehicle is in motion. No check engine lights or and warnings occur with the lifter failure, it is only identified by the driver through the tapping noise from the engine. Even a cursory review of forums and complaints reveals that lifter failure is widespread on this engine and that manufacturing defects have caused issues with this power train dating back to 2019, not just the recalled 2021-2024 models.” (NHTSA Complaint #11718762)
Airbag defects are safety-critical and may trigger California’s two-repair threshold under Cal. Civ. Code § 1793.22.

Owner reports include: “The contact's brother owned a 2020 Chevrolet Tahoe. The contact stated that while his brother was driving at an undisclosed speed, the vehicle crashed…”
Brake defects affecting safety may qualify for California’s two-repair threshold under Cal. Civ. Code § 1793.22, which applies to defects likely to cause death or serious bodily injury. The 2020 Chevrolet Tahoe has generated 6 NHTSA complaints related to braking, including ABS failures, grinding, reduced stopping power, and warning lights. Owner reports include: “While driving toward intersection, light changed to red. Applied pressure to brake pedal and pedal became extremely difficult to press. Vehicle was not slowing as expected with pedal pressure becoming very hard to press to slow vehicle. Warning on dash “Brake Assist” and Chevrolet app displays “Antilock Braking System” and text that states Schedule service now. If my wife would have been driving, this would have caused an accident. This is extremely dangerous condition that must be addressed with a corrective action taken by the manufacturer.” (NHTSA Complaint #11691929)

California’s Song-Beverly Consumer Warranty Act (Cal. Civ. Code §§ 1790–1795.8) is one of the strongest lemon laws in the United States. It protects buyers and lessees of new and certified pre-owned vehicles that develop substantial defects the manufacturer cannot repair after a reasonable number of attempts.
Under Cal. Civ. Code § 1793.22, a lemon law presumption is triggered when any of the following apply to your 2020 Chevrolet Tahoe:
Once the presumption is triggered, the burden shifts to Chevrolet to prove the vehicle is not a lemon. Under Cal. Civ. Code § 1794(d), Chevrolet must pay your attorney’s fees if you prevail — meaning qualified representation costs you nothing out of pocket.
If your 2020 Chevrolet Tahoe qualifies as a lemon under California law, Chevrolet may be legally required to:
Step 1: Document every repair visit. Keep all repair orders, work orders, and dealer invoices. Each visit counts as a repair attempt, even if the dealer says nothing is wrong.
Step 2: Keep returning for repairs. You must give Chevrolet a reasonable opportunity to fix the defect. Visit different authorized Chevrolet dealers if needed and ask for written documentation of each visit.
Step 3: Contact a California lemon law attorney. Once you believe the threshold has been met — 4 attempts for non-safety defects, 2 for safety defects, or 30 days out of service — contact an attorney for a free case evaluation. Under § 1794(d), Chevrolet pays your fees if you win.
Step 4: Send a demand letter. Your attorney will send Chevrolet a formal demand letter. Most California lemon law cases resolve through negotiation without going to trial.
Under Cal. Civ. Code § 1793.22, four or more repair attempts for the same non-safety defect, or two attempts for a safety-related defect, triggers the lemon law presumption. Additionally, 30 or more cumulative days out of service qualifies regardless of the number of repair attempts.
Yes. Under Cal. Civ. Code § 1794(d), Chevrolet is required to pay your reasonable attorney’s fees and court costs if you prevail in a lemon law claim. This means qualified lemon law representation is free to you if your case succeeds.
Yes. A recall is not required to file a lemon law claim. The Song-Beverly Act covers any substantial defect that impairs the use, value, or safety of the vehicle that the manufacturer cannot repair after a reasonable number of attempts. NHTSA complaints support the claim by establishing a pattern, but are not a prerequisite.
California lemon law claims are generally subject to a four-year statute of limitations from the date you discovered or should have discovered the defect. However, you must still be within the manufacturer’s original warranty period when the defect first appears. Contact an attorney promptly to preserve your rights.
