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 Mazda CX-5 include infotainment malfunctions, battery drain, warning lights, power window failures, and intermittent starting problems. 22 NHTSA complaints have been filed for this category. Owner reports include: “I purchased this vehicle as a used car from a dealership. On my way home, the infotainment panel began to shout at top volume that this is the volume that navigation would be set at. The volume was so loud that it was startling, and it continued on until I had to pull over. I contacted the dealer, but they offered no assistance. The car continues to control itself at the panel ferning with the use of android auto so that you can’t use your phone GPS for directions. The radio will control itself, changing stations, making loud beeps, and turning the volume up. There is no way to stop this feature because you can’t turn the system completely off while the car is on. I can find no way to fix this on my own. I have tried resets, but have seen ample information about other people having this problem online. This does not seem to be an unknown problem and I don’t know why there has not been issued a recall because it’s very dangerous.” (NHTSA Complaint #11690851)
Engine and cooling problems are among the most serious defects under California’s Song-Beverly Act.

Powertrain and transmission defects directly impair the vehicle’s core function and are generally considered substantial defects under California lemon law.

Owner reports include: “Started smelling burning oil in 2020 Mazda CX-5 non turbo with 34,000 miles. Auto shop states it is a cracked cylinder that will cost over $7,000 to repair.

I went to the drivers side door, which was open and reached in to turn the car off using the start/stop button. Before I could turn the car off, it started backing up and the door ran over me. The car was definitely in Park and the Brake was on. There was no reason for the parking brake to disengage.” (NHTSA Complaint #11546572)
As of the date of this review, no active recalls have been issued specifically for the 2020 Mazda CX-5. Recall status can change at any time. Check your VIN at NHTSA.gov/recalls for the most current information. The absence of a recall does not mean your vehicle is defect-free — many lemon law claims proceed without a recall on file.
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 Mazda CX-5:
Once the presumption is triggered, the burden shifts to Mazda to prove the vehicle is not a lemon. Under Cal. Civ. Code § 1794(d), Mazda must pay your attorney’s fees if you prevail — meaning qualified representation costs you nothing out of pocket.
If your 2020 Mazda CX-5 qualifies as a lemon under California law, Mazda 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 Mazda a reasonable opportunity to fix the defect. Visit different authorized Mazda 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), Mazda pays your fees if you win.
Step 4: Send a demand letter. Your attorney will send Mazda 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), Mazda 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.
