2019 Tesla Model 3 Problems

Half of the owners who gave a mileage had the problem by about 28,000 miles. Parts named most: Adaptive cruise control (126), Automatic emergency braking (78), Assist (61).

What to check before you buy

• Where it is safe, try the adaptive cruise and lane keeping on the test drive and watch for sudden braking or warnings with nothing there.
• Check the windshield in front of the camera and the bumper sensors for cracks, chips or poor repairs.
• Ask whether the windshield has been replaced. The camera has to be recalibrated afterward, and many shops skip it.

I was using Full self driving (FSD), but I notice the autopilot gets "impatient" when (correctly) stopped for a "long" period of time (~2 minutes), but will then try to proceed in dangerous conditions. 1. I had FSD engaged while waiting to make an uncontrolled left turn. The street I'm turning onto is busy, so both lanes are going at a…Owner complaint, filed 2026

Tesla FSD on HW3 vehicles has become very unstable. Users complain the car ping pongs within the lane and occasionally will steer onto the left or opposite lane. This seems to have happened after a recent update between Feb/March 2026. Growing reports of the same issue reported on Reddit. Ping pong tesla fsd Sources: r/TeslaFSD…Owner complaint, filed 2026

Half of the owners who gave a mileage had the problem by about 14,000 miles.

What to check before you buy

• Test every switch: windows, locks, mirrors, seat heaters, the screen, the backup camera, Bluetooth and every USB port.
• Watch the dash at startup. Every warning light should come on briefly and then go out.
• Have the battery and charging system tested. A weak alternator or battery drain shows up here.

Half of the owners who gave a mileage had the problem by about 9,000 miles.

What to check before you buy

• The air bag (SRS) light should come on at startup and go out within a few seconds. If it stays on, the system may not work in a crash.
• Air bag recalls are some of the most serious. Check this exact VIN for open recalls and get proof any recall work was done.

My 2019 Tesla Model 3 (approx. 95,000 miles) displays a persistent 'Front passenger safety restraint system' alert. The car drives normally and there has been no crash, fire, or injury. Tesla Service's estimate lists $631.60 for the alert diagnosis, $458.50 to replace the front passenger seat Occupant Classification System (OCS), and…Owner complaint, filed 2026

Front passenger Occupant Classification System (OCS) failed on its own, without accident, misuse, or modification, at low mileage. The fault disables proper airbag deployment logic for the front passenger seat. Tesla has issued multiple service bulletins acknowledging this as a known condition. **Vehicle Identification Number (VIN):**…Owner complaint, filed 2026

Half of the owners who gave a mileage had the problem by about 10,000 miles.

What to check before you buy

• Check the tires for uneven wear on the inside or outside edges, a sign of alignment or suspension trouble.
• Look behind the wheels for oily, wet shocks or struts.

Over a period of several weeks, the front suspension increasingly made noise (squeaking and groaning) and felt loose when turning and going over bumps. The front control arms were replaced 10/31/24. The problem has begun recurring over the last few months, with the same noise occurring and progressively worsening.Owner complaint, filed 2026

Noise came from front left wheel while driving around a turn. Later the same day another noise when turning the wheel when leaving a parking spot. Steering felt strange. It was late at night, so left the vehicle until the morning. In the morning, discovered a large bolt in front of the vehicle. The front left wheel was turned differently…Owner complaint, filed 2026

What to check before you buy

• Pull out and latch every seat belt, and let each one retract on its own.

Half of the owners who gave a mileage had the problem by about 5,000 miles.

It certainly looks like this is a result of the accident avoidance…Owner complaint, filed 2023

Half of the owners who gave a mileage had the problem by about 7,000 miles.

What to check before you buy

• The pedal should feel firm and the car should stop straight without pulling, grinding or a pulsing pedal.
• The ABS and stability control lights should go out after startup and stay out.
• Look through the wheels at the rotors. A deep lip on the edge means brakes are due soon, which is a fair thing to negotiate on.

What to check before you buy

• Turn the wheel lock to lock while parked and listen for groaning, clicking or binding.

Half of the owners who gave a mileage had the problem by about 4,000 miles. Parts named most: Body (23).

What to check before you buy

• Look underneath with a flashlight. Utah road salt is hard on frames, brake lines and the bottoms of doors.
• Open and close every door, the hood and the liftgate, and lock and unlock each one.
• Use a paint thickness gauge and compare panels. A panel that reads very differently from the rest has likely been repaired.

Component: Exterior Door Handle (Front Passenger) Incident Description: A latent manufacturing defect resulted in the structural delamination of the interior chrome plating on the front passenger door handle. This failure occurred after the last use of the handle, creating a razor-sharp metallic edge that was not visible during a normal…Owner complaint, filed 2026

The chrome lamination/sticker is peeling from the underside of the door handles. This peeling causes an extremely sharp edge that cut my finger. This issue is noted rather constantly over the internet. The sharp edge is hidden by the retracting mechanism of the door handles, and so you don’t see it until you grab it and cut yourself.Owner complaint, filed 2026

Half of the owners who gave a mileage had the problem by about 6,000 miles.

What to check before you buy

• Drive it from cold if you can. Shifts should be smooth in every gear, including reverse.
• Feel for slipping (revs rise without the car speeding up), shudder at low speed and a delay when you put it in gear.
• Listen for whining, which is a common CVT complaint, and clunks when you go from drive to reverse.
• If it has 4WD or AWD, engage it on the test drive and ask when the transmission and differential fluids were last changed.

What to check before you buy

• Read the four-digit DOT date on each tire. Tires older than about six years should be replaced, whatever the tread looks like.
• Check tread depth on all four. On AWD vehicles all four tires should match.
• The tire pressure light should go out after startup.

What to check before you buy

• Smell around the engine bay and under the rear of the car for raw fuel.
• On the test drive, accelerate firmly from a stop and up a grade. Stumbling, surging or a flashing check engine light are red flags.
• Fuel pump recalls are common. Check this exact VIN for open recalls before you buy.

Charging behavior is irregular, and the vehicle’s energy regeneration is inconsistent. There was no crash, fire, or…Owner complaint, filed 2025

What to check before you buy

• Ask the seller not to warm the car up, and start it cold. Listen for ticking, knocking or a rough idle in the first minute.
• Pull the oil dipstick and the oil cap. Low oil, a gasoline smell or a milky film on the cap are reasons to walk away or get an inspection.
• Plug in an OBD2 scanner. Stored or pending codes matter, and so do readiness monitors that show "not ready", which usually means the codes were cleared right before the sale.
• Ask for oil change records. A gap in the records on a model known for engine complaints is a negotiating point at minimum.
